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.

Solutions for PTC Heater Cracks

Use of Fin PTC Air Heaters provides a simple solution for cracks, bursts, and burns; specifically developed to prevent typical issues encountered with coil or conventional heaters, these heaters are self-regulating, meaning they won’t overheat.

By eliminating the risk of overheating, these heaters offer greater operating efficiency, stable electronic response, and longer life expectancy.

Extremely versatile, Fin PTC Air Heaters can be used in a wide range of applications, including electric automotive vehicles, general dehumidification, and thermal retention, and are frequently found in electronic household appliances such as hand dryers, irons, laminating machines, air conditioners, and adhesive sealing machines.

Temperature Coefficient Heater Applications | Pelonis Tech

Offering simple troubleshooting solutions, low maintenance, and highly efficient heat transfer, Positive Temperature Coefficient (PTC) heaters — specialized resistors that vary resistance in accordance with their temperature — offer versatile, easy-to-use solutions for a range of industries.

Thermistor Technology

PTC heating for different industriesA resistor that changes resistance as a function of its temperature is also referred to as a thermistor.

Thermistors increase their resistance when temperature increases, thus resulting in a Positive Temperature Coefficient.

An NTC thermistor, meanwhile, decreases its resistance when temperature increases, resulting in a Negative Temperature Coefficient.

When crafted with very pure semiconducting ceramic, PTC heating discs, fins, and honeycombs make ideal solutions for specialty applications.

PTC heaters can quickly create enormous heat transfers in small spaces; in fact, these heaters can produce an instantaneous flow of heat that is 50% hotter than the flow created by more conventional oil or ceramic chip heaters.

Industries and Applications

With the ability to perform in extremely small spaces with superior heat transfer and safe, powerful, and energy-efficient operation, PTC heaters offer several benefits across a wide range of industries.

Food and Beverage

Versatile and compact, PTC heaters are especially useful in the food and beverage industry. Used for heating and temperature control in various appliances, including coffee hot plates, food warmers, and temperature-controlled containers, PTC heaters allow for consistency and reliability in a range of applications.


With superior dehumidification and anti-condensation properties, PTC heaters are ideal for food safety, food processing, and other high-moisture manufacturing processes. As moisture problems take on increasing importance in plant environments and USDA and federal requirements grow stricter, processors are looking to PTC heating technology to reduce humidity and resulting bacteria growth on food machinery and equipment.

RoHS Compliance - What Is It?

Posted by Sam Pelonis | Feb 3, 2014 8:50:00 AM | 0 Comments

RoHS (Restriction of Hazardous Substances) is a directive from the European Union (EU) that restricts the use of six hazardous materials commonly found in electrical and electronic products. In particular, it specifies maximum levels for lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers.

All companies that sell electrical or electronic products or components to RoHS countries must adhere to these regulations. The EU will grant a company RoHS certification after reviewing its documentation, completing a thorough audit and performing on-site

Protecting Against the Dangers of Toxic Waste with RoHS

RoHSThe RoHS directive took effect in 2006 and was a response to increased public scrutiny on the impact of electronics on the environment. According to DoSomething.org, a non-profit organization that advocates for social change, electronic waste “represents 2 percent of America’s trash in landfills, but it equals 70 percent of overall toxic waste.” This waste can lead to death, illness and birth defects in all those who are exposed. To protect people against the dangers of toxic waste, a total of 27 countries now require RoHS compliant units.

The dangerous substances that RoHS seeks to control are found in a wide range of consumer electronics. Lead, one of these restricted substances, can be found in cables such as USB charging cables and power cords. Lead is also present in batteries, printed circuit board finishes, and the glass on television screens and cameras.

Cadmium, another restricted substance, is present in certain photocells and batteries. To achieve RoHS certification, companies must keep the amount of lead in their products below 1000 ppm, and cadmium below 100 ppm. They must also keep levels of hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers below 1000 ppm and mercury below 100 ppm.

Benefits of RoHS Compliance

In addition to a cleaner environment, companies that comply with the RoHS directive can expect to gain a number of benefits. Stricter regulations require “tighter process control, overall reduced number of defects and increased production efficiency.”

They also necessitate more communication across the supply chain and skills in the workforce. Finally, RoHS compliance confers a competitive advantage to manufacturers and companies for those markets that have just begun to consider the implementation of environmental standards. 

Companies in the consumer electronics industry can help reduce the danger of toxicity to humans and the environment by pursuing RoHS certification. They will also contribute to the growing momentum of initiatives concerning sustainability and energy efficiency.

Pelonis Technologies is one of those companies. At Pelonis, we are committed to developing fans and motors that are not only high-quality but also environmentally friendly. We’re proud to be a RoHS compliant company.
