The Importance of Selecting the Right Cooling System


In the medical equipment industry, proper component functionality and performance is of utmost importance, as failures can cause dangerous malfunctions and delays that put patients at risk. When selecting a cooling system for your medical equipment application, it’s important to consider your project’s specific temperature and application needs. This will help to ensure longevity and reliability in your medical equipment.

AC blowers — machines that provide air flow to facilitate various machine processes through the use of rotating blades — are often used in medical equipment to provide reliable, efficient air movement. For instance, AC blowers are utilized in medical and surgical beds to pump airflow up through mattresses, providing air circulation that prevents patients from experiencing pressure sores, skin shearing, hot flashes, and night sweats.

AC blowers can also have a great impact on the performance of thermal imaging systems, as many medical devices lose efficacy after critical temperature is reached, causing delays and added costs.

The Problem

Because medical device performance can suffer after reaching critical temperature, equipment such as MRIs, computed tomography (CT) devices, ultrasounds, and radiography (X-ray) machines are susceptible to subpar or slowed functioning. All of these devices rely on enclosure cooling to keep temperatures at optimal levels, as even slight fluctuations can affect performance. The FDA, however, helps maintain near-perfect (≥95%) repeatability and reproducibility of results in such equipment.

Because imaging technology designers generally have a narrow temperature range to work with, usually 50 ºF (10 ºC) between cabinet interior and exterior ambient temperature, cooling systems must be of the highest quality — dependable, quiet, and high performing, while also meeting the hygienic requirements of the medical industry.

The Solution

Typically used for sealed enclosures or devices, heat exchangers circulate hot air inside a device over an extended surface area, like internal fins, and circulate cooler external air over external fins. This keeps the interior temperature consistently warmer than the outside temperature.  If devices or enclosures are not sealed, however, small, silent, high-performing fans for medical equipment manufacturing can be used, which are less expensive and just as effective for non-sealed applications. Because most medical devices require sealing to maintain sanitation, heat exchangers are an ideal option to keep equipment functioning optimally and thereby reduce downtime and additional maintenance costs.

When incorporating a heat exchanger into medical equipment that requires a fan, be sure the power supply can accommodate the additional required power.

Cooling Solutions from Pelonis: The B1793 Blower

As a leading manufacturer of heating and cooling technologies, Pelonis is proud to offer a wide array of cooling options, including axial AC and brushless DC fans, as well as high-technology motors and OEM manufacturing solutions. Our B1793 TITAN AC blower, in particular, is ideal for use in the medical equipment industry.

With a patented engineered aluminum enclosure that acts as a heat sink, the B1793 is extremely heat resistant. This allows for cooler surface temperatures and reduced internal component wear. It also features an isolated open collector tachometer, which monitors running speed and locked rotor protection, ensuring automatic restart if the motor is released from a locked state. The B1793 blower also includes PWM operation that enables it to operate at various speed settings and it is a compact unit, allowing for easy installation and use in smaller medical devices.

Five Cost Saving Factors You May Not Have Considered

Posted by Sam Pelonis | Jun 16, 2014 10:00:00 AM | 0 Comments

If you own a business be it big or small, you know how critical it is to keep costs down.  Everyday is a battle to find new ways to save money all while keeping quality levels high. Often in the electronics industry, there are inventive and even hidden heating and cooling cost saving factors not instantly thought about. In this blog, we will cover the top five ways Pelonis believes can help electronics manufacturers improve their bottom-line.

1.Heat Pipes

HeatPipeThe overheating of electronics is a topic that will run through most of this blog’s theme. It is one of the top “killers” of electronics thus manufacturers are constantly trying to find ways to eliminate or lessen its effects. One handy and simple way to reduce heat-related problems is with a heat pipe. Heat pipes are passive heat transfer systems with high effective thermal conductivity. Typically made with copper or aluminum, these sealed hollow tubes are lightweight and transfer heat away from machinery over long distances without any moving parts. Heat pipes, which use evaporative cooling technology, were first used by NASA but have found their way into modern electronics and computers. They are an easy and cost-effective heat transfer method.

2.Size of the Device

The cost of materials is a major issue for any manufacturer. This is especially the case in the electronics industry. Raw material costs are always in flux and some, like gold and silver, are always on the high end. Perhaps the most obvious ways to reduce your exposure to fluctuating prices is to use fewer materials. The best way to accomplish this task is to focus on miniaturizing your products. While this might come with some greater upfront costs, it will save you over the long haul. Smaller products, means lower overall costs. As well, smaller devices in general have a lower cost for heating and cooling.   

3. PTC Heating Combined with Micro Cooling

Positive Temperature Coefficient (PTC) heaters are specialized heating discs/elements that combine outstanding heat transfer with a reduced need for space. Available as both a Fin element or in a honeycomb form, PTC heating elements replace resistance wires with ceramic chips. PTC heating allows for quick cool downs and do not require overheating protection. Thanks to this higher level of safety, they will reduce downtime, plus their smaller size plays directly into point #2 on our list.

4. Cost of Manufacturing

Finding a manufacturer that can combine competitive pricing and exceptional quality is the goal of every business. At Pelonis, we find that one of the best ways to lower your manufacturing costs is flexibility. It allows you to respond with speed and cost-effectiveness to any type of order.  This flexibility crosses over into basic design as well.  Being flexible about what types of heating and cooling options will work best provides an opportunity to save, rather than being rigid about that decision.

5. Long-Term Maintenance and Cost of Operation

If you are forced to constantly upgrade or repair equipment, it will cause costs to balloon. Much like reducing the size of a device, boosting long-term maintenance and lowering cost of operations with high-quality heating and cooling fans may raise upfront costs, but you will eliminate headaches, downtime, and lost productivity in the long run.

If you want even more cost saving tips, please contact Pelonis today! We are always thinking of new ways to save our customers time and money.
