Benefits of Adding Thermostat Controls to Cabinet Coolers

dsc00493

The image above shows a NEMA 4 Cabinet Cooler after years of use in a food production facility.  The head electrician at the facility which uses this unit, contacted me regarding the possibility of installing thermostat controls on a pre-installed Cabinet Cooler systems.  Apparently there are multiple EXAIR Cabinet Coolers in use around this facility, and as part of an improvement to compressed air efficiency, this facility wanted to explore automated regulation of the temperature in these enclosures (through thermostats). THis customer inquiry was about how to go about implementing such an upgrade.

It was refreshing for the end user to find that we have mechanical thermostat controls, solenoids, and even digital thermostatic solutions available from stock, making the upgrading process easy and pain-free.  After some conversations over the phone and emailing part numbers along with our Cabinet Cooler Installation and Maintenance Guide, which outlines how to install the thermostat for our Cabinet Cooler systems, this customer had everything required to do exactly what they needed in their facility.  (In this case, our model 9016 Solenoid Valve and Thermostat Kit met the voltage and compressed air flow requirements needed for the application.)

Providing efficient, controlled, and reliable solutions for industrial applications is all we do at EXAIR.  If you have an application in need of a complete solution, or just an upgrade, contact an EXAIR Application Engineer.  We’re happy to help.

For the record, EXAIR recommends the use of 316 grade stainless steel Cabinet Coolers in food production facilities

Save Money By Using Your Own Thermostat? Well…

Last week, I wrote about what a great idea it is to use a thermostat with a Cabinet Cooler System. I’ll let another cat out of the bag right now and tell you that there are less expensive thermostats than ours. But just like the savings you might realize on the purchase by foregoing a thermostat, using a poorly specified thermostat can also be the last savings you see.

In a Cabinet Cooler System application, we’re refrigerating air. This makes for a cool, clean, and dry atmosphere for your electrical & electronic components to operate in.

UL Listed & CE Compliant, EXAIR Cabinet Cooler Systems maintain NEMA 4, 4X, or 12 integrity.

Not all thermostats are designed to read air temperature – in fact, a LOT of common, commercially available thermostats are designed for use with liquid. Using these to control air temperature will lead to slow response times. That means one of two things will happen:

When the air inside the enclosure is cooled to the thermostat’s set-point temperature, it won’t shut off the compressed air flow to the Cabinet Cooler unit, resulting in unnecessary compressed air consumption.  And that’s a shame.

OR:

When the air inside the enclosure is heated to the thermostat’s set-point temperature, it won’t start the compressed air flow to the Cabinet Cooler unit, resulting in a potential overheating of those expensive…or critical…or both…electronic components.  And that’s a REAL shame.

We don’t want to see you using any more compressed air than you need to.  And we SERIOUSLY don’t want to see you fry your electronics.  If you’d like to find out more about EXAIR Cabinet Cooler Systems, give me a call.
