Inside the panel is a 150 mm diameter fan which is pulling in an air and steam mixture which is causing the temperature inside the cabinet to climb to unacceptable levels. The result is that the motor drives located inside the panel are failing, causing a tremendous cost for replacement and downtime.

Our local distributor worked with the customer to acquire the necessary data for us to calculate heat load within the panel. We determined the customer needed our model HT4880SS-240 Cabinet Cooler System to keep their internal panel temperature at a more reasonable level, year round, even in their worst case scenario with constant steam exhaust in the area.

One key component to success in this application will be removal of the fan and covering of the vent that it once occupied in order to keep the steam from being drawn into the inside of the panel. Historically, fans have been the go to strategy for keeping panels like this cool. However, in this situation, as in many others, the fans pull in un-wanted contamination. There isn’t any filter that can keep steam from getting inside and causing all sorts of problems with condensate forming on internal components, thus promoting corrosion and heat related failures.

The Cabinet Cooler System will provide a filtered, and dry source of cooling airflow which will produce a slight positive purge pressure on the panel to keep such harmful outside atmospheres from entering into the panel. This assures, long life for the panel components and much less hassle and problems associated with heat related failures.

EXAIR Cabinet Cooler Systems Control Humidity While Maintaining Internal Temperature

As the weather in the Northern Hemisphere changes over from winter to spring and temperatures start to climb, it is slowly becoming necessary for customers to utilize the Cabinet Cooler Systems to keep control panels cool.

One such situation involved a customer who was building a panel for his client in Malaysia. Malaysia is about 3 degrees north of the Equator, so it is what I would call a semi-tropical if not tropical environment. And such places are quite high in humidity levels. This customer had a client who was in the palm oil processing industry which is quite big in Malaysia. He needed a Cabinet Cooler System to generate about 1000 Btu/hr. of cooling power in a NEMA 12 type system. So I recommended he go with a 1700 Btu/hr. Cabinet Cooler System so he had plenty of capacity. I also recommended he go with 24 VDC thermostat control so he could easily pull the power out from within his panel and not have to run any new circuits.

As the customer duly noted, the fact that the Cabinet Cooler System purges the cabinet with clean, cool and dry compressed air allows for the humidity levels to hang down at a much lower level around 40 – 50% RH instead of up around 80 – 90%. This is attributed to the processing and drying of the compressed air at the production point before it is sent out to the facility and again at the point of use with the included, 5 micron, compressed air filter/separator that comes with each system.

Previously, the customer was using only the small, DC type fans to pull that hot, humid air through the panel which led to many corrosion issues and did not relieve the heat issue at all. With this new improvement, the end user no longer has to worry about such issues. Also, there is virtually no maintenance for this system which produces much longer up-times for the customer as there are no moving parts to wear out. Overall, it was a good recommendation in this case as the Cabinet Cooler System was handling multiple, previously negative issues. Now the pain has been taken away and the end user can move on to solving other, more pressing problems.

Snow Snow Go Away

Enough already! Enough is enough! I am done with Winter!

 

I’m sure that I am expressing the sentiments of  most the nation.   In my sixty some years I cannot remember a winter this severe. I shouldn’t complain though as I have heat and electricity, unlike those who are caught up in the propane shortage.

When you come to think of it, folks in the extreme northern climates deal with this kind of weather as a normal routine. It just proves that we have become so accustomed to a controlled environment, that we have lost our resilience and the ability to cope  outside our comfort zone. I am going to take this as a wake up call and stop complaining and go take the dog for a walk.

With cold gripping the country, you would not think that we would be getting calls for our Cabinet Cooler Systems. Quite the contrary as many control panels are in very warm environments such as foundries, bakeries, etc. Also Summer will be coming soon. It would be best to get a Cabinet Cooler System sized up and ready rather than wait for a heat related shutdown.

CCSizing

Our application engineers are available to help you size up your cooling requirements. We have an online form to outline  the data we will need to size one up properly. One of our engineers will do the calculations for you and get back to you promptly. Remember last summer when that one panel kept tripping out or alarming every time it got too hot…You may be cold now, but don’t let the heat sneak up on you.
