Avoid Cracks, Bursts, and Burns in PTC Heaters

Posted by Sam Pelonis | Jun 20, 2017 4:47:00 PM | 1 Comment

Under certain airflow conditions, PTC (positive temperature coefficient) heating solutions may fail as a result of cracking, bursting, or even burning.

PTC Heater Burns These issues are commonly caused by poor airflow or poor, incomplete, or improper combustion: Dirty or otherwise obstructed vents can lead to poor airflow, which in turn overworks the furnace and causes premature damage, while subpar combustion causes burners to run longer and hotter in order to achieve the same amount of heating output.


Long periods of use can also cause failures; over time, the stress caused by normal expansion and contraction of a furnace as it turns on and off in its cycles can result in cracks.

Save Money on Industrial Air Heaters

Posted by Sam Pelonis | Oct 26, 2015 1:00:00 PM | 0 Comments

The industrial heating of air and water can be expensive. But you can effectively heat both air and water for industrial applications without breaking the bank. In fact, energy experts at the U.S. Department of Energy (DOE) found that it is possible to save millions of dollars in industrial settings, such as energy-intensive manufacturing plants, simply by improving the energy efficiency of steam or process heating systems. To save money on the industrial heating of air and water, be sure to keep the following in mind.

Use proper furnace insulation techniquesUse proper furnace insulation techniques. Simply by properly insulating furnaces, a major industrial plant can potentially save 1 million MMBtu of natural gas per year, according to energy-efficiency specialists in the DOE Industrial Technologies Program (ITP). That translates into a monetary savings of close to $12 million annually, as well as annual carbon dioxide savings of 124,000 metric tons. Proper insulation of the furnace also prolongs operating life. How can you ensure that your furnace is properly insulated?

• First, make sure to check heat transfer surfaces. Particularly for industrial process heating systems, making sure heat transfer surfaces are free from any kind of soot, scale, or oxide deposits will significantly improve system efficiency. Also, be sure to monitor conditions that could produce deposits on heat transfer surfaces, including low air to fuel ratios, poor fuel preparation, malfunctioning burners, and corrosive gases or constituents in the heating medium. 


• Second, you will want to reduce air infiltration in furnaces. Air leakage into the furnace or leakage of flue gases from the furnace into the ambient air can occur via any kind of cracks or openings around the doors, joints, and hearth seals. Properly insulating your furnace means sealing up these small openings. Even the smallest crack can have an effect on efficiency, driving up your heating costs.

Keep insulating material from becoming wet. When insulating materials become wet, there can be a drop in voltage. Saturated or wet insulation elements lose their electrical insulation and subsequently leak voltage to the ground. As a result, this increases the overall current draw and decreases the efficiency of the furnace.

Reduce watt density. In order to maximize the performance and efficiency of a heater, it is advantageous to reduce watt density. When watt density is too high, it can cause localized overheating. If you are using a high watt density for viscous, poorly conductive, or unusually heavy fluids, you might want to consider using higher temperature protectors or de-rating heaters, as this will allow you to lower the watt density.

Choose an immersion heater. Immersion heaters offer a number of advantages, including energy efficiency. They boast an incredibly high thermal conductivity and, therefore, are significantly more efficient than other metallic and non-metallic heating elements. To save money on the industrial heating of air and water, an immersion heater is an excellent choice.

Ensure the heater guard is properly installed. Heater guards can be easily installed at the inlet or supply of any water heater, and they work to keep dirt, rust, silt, and sediment out of your water heater, ensuring that your water heater operates optimally, which saves and energy and prolongs the lifespan of your device. Proper installation of the heater guard ensures efficient heat transmission as well as improved temperature regulation.

Check the thermal conductivity of the medium being heated. The medium you are heating will significantly affect the efficiency of your heating operations. The higher the thermal conductivity of the medium, the easier it will be to heat it and the more efficient the operation will be. Always check the thermal conductivity of the medium being heated.

Ensure your water tank is properly insulated. Just like you need to properly insulate your furnace, you also need to properly insulate your water tank in order to maximize energy efficiency. Proper insulation can actually reduce standby heat losses by up to 45 percent, which translates into monetary savings of up to 9 percent on your heating bill.

Maintenance Tips for Heating & Cooling Systems

Posted by Sam Pelonis | Jun 29, 2015 7:00:00 AM | 0 Comments

When customers choose to undertake custom heating or cooling projects, they may not always make as many considerations as industry professionals.

There are a lot of questions that need to be addressed before any installation can begin, such as those pertaining to the location and characteristics of the desired system, and the cost and energy concerns of the entire project.

There are also many questions to consider when working on the systems once they are set in place; the slightest issue can increase the chances of component degradation or eventual failure. Depending on whether you are working on either a heating or cooling system, there are different questions that are vital to keep in mind.

PTC_heaterHeating Systems

Q:  Is maintenance the same for all kinds of heating systems?

A:  Since heating systems differ slightly, maintenance on those systems will also differ.

For example: household heating applications rely on the thermal conduction of the building, whereas transportation heating applications utilize energy from the vehicle itself. Some applications rely on thermostats to regulate energy, and others are self-limiting.

In any case, you’ll want to consider the specific energy concerns and individual components of the application before making repairs.           

Q:  My heating system is creating unusually high utility costs—how can I resolve the issue?

A:  Higher energy costs can be indicative of poor energy efficiency. The secondary limiting devices that some heating systems depend on can malfunction, leading to an influx of heat energy—which in turn leads to higher energy costs.

To combat this issue, you should regularly check your system for any signs of overheating and replace any defective parts.

Q:  Do PTC heaters need constant maintenance?

A:  A PTC heater has a much longer service life than a traditional resistance heater. PTC heating limits the amount of energy flowing through a system, making them less prone to overheating or shorting out. Like with any machinery, it is possible for PTC heaters to malfunction—if you notice any problems, check the heater for any faulty circuitry.

HVAC_fanCooling Systems

Q:  Is maintenance the same for fans and blowers?

A:  Maintenance will be slightly different for fans and blowers since each has unique airflow and pressure characteristics, but generally you should watch for signs of fatigue on belts, bearings, sheaves, and other components. DC fans, DC blowers, micro fans and cross flow fans will each have some differences when it comes to maintenace.

Q:  Why are there airflow problems in the system?

A:  Your cooling (and heating) system can accumulate debris or other contaminants, which can lead to poor performance and damaged components over time.

Make sure to keep these components clean. Issues like fan degradation (caused corrosive gases or abrasive particles) can be averted with periodic inspection of the system for any flow irregularities.

Q:  What is another component that needs to be checked regularly?

A:  The condition of the fan’s motor is vital to the proper operation of the system. You can use methods such as vibration analysis—of the motor speed and blade pass frequency—to preemptively detect issues within the motor windings. You can also measure insulation resistance at certain voltages to test the motor windings.

How to Create Specifications for a Heating and Cooling System

Posted by Sam Pelonis | Dec 22, 2014 7:00:00 AM | 0 Comments

Problem-free operation of heating and cooling systems begins well before consumers even switch on their machines.

During the spec phase, designers of these systems must factor in several considerations while asking themselves pertinent questions. Here are three such questions accompanied by some helpful answers. 

1. Is the heating/cooling system properly sized?

Cooling_FanProper sizing is crucial for ideal speccing of these systems. When calculating the heating and cooling requirements for a given facility, it is important to avoid the olden practice of “rule of thumb” sizing, which equates system size with a facility’s total square footage.

Regarding sizing, be sure to consider these factors: cubic footage to be heated and cooled, insulation and rate of air infiltration, and industry standard protocols for product sizing. These design points will help heating and cooling systems avoid serious issues in the future, including short cycling and excessive equipment wear.

2. With all the different temperature control devices on the market, which is the best for the application?

Delivering optimum heating and cooling is one of the expected outcomes when speccing a new system. Thermal controls are an important part of maintaining the correct temperature; there are various thermal control products available on the market, enabling you to maintain a comfortable environment regardless of building size.

A simple electromechanical control may be all that is required for some applications. Other situations may require more elaborate controls and sensors for multiple zones. In addition, predictable schedules may demand newer controls, incorporating artificial intelligence or remote web-based controls for warming and cooling prior to arriving at the facility.

3. What potential electrical problems could affect the performance of the system?

Today’s heating and cooling systems offer many benefits that aren’t available in older systems. However, most of the electronics in modern systems can create issues not found in electromechanical systems, such as a low voltage specification; if the specification isn’t met, motor life will shorten and cause the electronic component to malfunction.

When speccing a system that will use backup power, it’s important to verify that all incoming power sources meet the requirements of the heating/cooling system. Frequently, this means the power supply meets a combined variation in voltage and frequency of 10 percent, provided the frequency variation doesn’t exceed five percent of the rated frequency.

Common Signs of Wear to Check for in Preventative Maintenance

Posted by Sam Pelonis | Sep 29, 2014 3:48:00 PM | 0 Comments

Industrial heating and cooling systems can succumb to various issues during their life cycles. If any complications in your system are left unattended, it could result in higher utility costs, damaged parts and equipment, or exposure to hazardous air quality. In many cases, these issues can be avoided by utilizing preventative maintenance techniques. 

To comply with industry standards, heating and cooling systems must undergo annual preventative maintenance; it is good practice to prepare for upcoming seasons, as different temperatures and moisture levels can adversely affect different systems.

Since operating and energy costs can accumulate as time progresses, it’s in the best interest of you and your customers to keep heating and cooling systems running as efficiently as possible. You should be conducting routine inspection to ensure all components are functioning correctly.

Pay attention to the signs

PH2207-L4When performing preventative maintenance, there are several common signs that you should always be on the lookout for.

  • Listen for any abnormal noises. If you hear sounds emanating from the system that seem out of the ordinary, that could mean fan blades or sheet metal panels are loose, and thus vibrating. Continuing to listen will help identify the noise’s origin; once you find it, thoroughly and carefully inspect the blades and motor. Check if fans and motors are rotating easily—if they aren’t, you need to immediately replace components.  
  • Unusual odors could be a problem. Part of the inspection process involves using your sense of smell. If the air around the system seems musty or moldy, there are a few possible explanations: standing water could be building up in drain pans; drain lines could be clogged or improperly installed; there could be ductwork leaks; or debris could be in or near air ducts. You can test any suspect areas with electronic leak detectors. Any kind of burning smell in the system can be caused by loose electrical connections and overheating parts. This is a potential fire hazard, so you need to act swiftly if you smell burning.
  • Lack of airflow. Lack or airflow may indicate a problem. You’ll need to make sure fans are rotating smoothly; also, check for any type debris that could be obstructing the system. When heating and cooling systems have substantially low airflow, it can dramatically reduce the life cycle of compressors—in fact, this is a major cause of compressor failure.
  • Look for discolorations. One of the more obvious signs of wear in your system is any discoloration; this can signal corrosion on various parts and equipment. If you see any abnormally colored water building up, rust might be inside your system. These issues can also indicate a moisture imbalance within the system.

Always remain vigilant

When you are open to these common signs of wear, you can prevent several issues from afflicting industrial heating and cooling systems. Being attentive and using these guidelines will enable you to lower maintenance costs and prolong the service life of your parts and equipment.

Three Unexpected Types and Uses of Heating Systems

Posted by Sam Pelonis | Sep 2, 2014 10:30:00 AM | 0 Comments

So, you think you know everything there is to know about heating systems? Not so fast. There are plenty of unexpected types and uses of heating systems. Here are some that you might not have thought of.

1. Heated Turf

Several companies specialize in creating heating systems for outdoor sports fields, such as soccer pitches and football playing fields. Heating Solutions International (HSI), a partner of the European Turf Group, recently built four heated turf soccer pitches in Norway that radiate up to 300 kilowatts to enable play on fields that otherwise would be covered in frost or snow.

TurfHeatingIn the U.S., several football and baseball fields are now underpinned with turf heating systems. The Philadelphia Eagles, Washington Redskins, and New England Patriots are just a few of the NFL teams that have taken advantage of the technology.

And it’s not just to keep the sod from freezing over in colder climates. At Seattle’s Safeco Field, the Seattle Mariners use turf heating to get the grass to feel like spring has arrived early, just in time for the start of baseball season. Even the legendary “frozen tundra” of Lambeau Field in Green Bay, Wis.,was long ago fitted with a heating system that keeps the turf warm during the chilly winter months.

2. Custom Radiant Heating for Floors

One of the most efficient ways of heating your home comes by way of radiant floor heating systems. While not well known, these in floor heating systems have been around for many years and are recommended by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) as being able to keep homeowners comfortable at temperatures 6-8°F lower than with convective systems. According to the U.S. Department of Energy, “The systems depend largely on radiant heat transfer -- the delivery of heat directly from the hot surface to the people and objects in the room via infrared radiation.” They can even be used in industrial applications.

3. Infrared Heating

Infrared emitters and modules are often overlooked in the roles they play in a wide variety of industries. These processes cover everything from converting metals, adhesives, plastics, and other materials to browning meats, desserts, chocolates, confections, and more, according to the company.

PTC Heating Technology Benefits

Posted by Sam Pelonis | Aug 18, 2014 11:00:00 AM | 10 Comments

It can be difficult to find the right heating technology for your needs. Most industrial and commercial customers demand an innovative combination of efficiency and safety in their heaters.

At Pelonis, we find that the perfect solution is PTC heating. PTC (Positive Temperature Coefficient) is a unique technology that eschews traditional resistance wire and replaces it with ceramic stones or chips.

This simple switch in materials is what makes PTC electric heaters superior to traditional coil electric heaters. In this blog, we will cover what we believe to be the top three benefits of modern PTC heating technology.

1. Increased Levels of Safety

8689On its own, this is a powerful reason to make the switch to PTC technology. Traditional heaters run at internal temperatures that can exceed 900°F (482°C). Compare this with PTC heaters that usually run at 518°F (270°C). As you might expect, lower running temperatures will always bring an increase in safety. As well, because PTC stones do not generate heat at a constant rate like resistance wires, they will cool down quickly to avoid overheating. PTC heaters are also less susceptible to overheating due to scale buildup or sludge.

Turn up the Heat, Reduce the Cost

2. Longer Lasting

As with any piece of equipment, the longer internal temperatures stay high, the shorter the lifespan. Much like an overheating cellphone or laptop, a heater will not last too long if allowed to operate at extreme temperatures. As mentioned above, PTC heaters only generate the heat necessary to fulfill its preprogramed goal. This limits overheating which means less chance for it to burn out.

3. Lower Operating Costs and Downtime

We have established that PTC heaters are safer and longer lasting. It only makes sense then that these benefits will directly affect your bottom line in a positive way. A self-limiting PTC system means less money spent on special equipment to avoid overheating like trip protectors. As well, the smoother running PTC heater breaks down less and needs less maintenance.

At Pelonis, we are proud to offer our clients the latest in PTC heating technology. Our Honeycomb PTC Heaters offer you proprietary heating discs that are made from a revolutionary ceramic material that has 1,200 round/triangle shaped holes. These unique discs heat 100% of the airflow across their entire surface, which allows them to get 50% hotter than conventional coil heaters. We also carry some innovative Honeycomb PTC holder assemblies and Fin PTC heating elements.

4. Proven Track Record

Back in 2012, PTC changed the industry for the better with our new, revolutionary, Sealed Bearing System (SBS)

As you know, SBS is a cost effective and high performance, environmental DC fan bearing solution.  It increases cooling fan life by actively reducing damaging oil leaks and dust contamination.  In order to understand the real impact of SBS, you first need to take a quick look inside the manufacturing of DC fans.

With thicker, high-additive lubrication, there is less evaporation. This, combined with a lower oil content, means that our lubricant gives the superior ball bearing design the long-lasting edge you’re looking for. 

Pelonis’ customers have found that our SBS is a very practical solution for DC fan application that requires the benefits of both sleeve and ball bearings.
