Thermoelectric Cooling Frequently Asked Questions

Get answers to common questions regarding our enclosures and cooling products.


What are the advantages of EIC’s TE coolers vs. a compressor based air conditioner?

Thermoelectric air conditioners are extremely reliable, with no moving parts except fans, no filters to change, no Freon or copper tubing, have multiple mounting orientation options and no regular maintenance. For an in depth analysis of the advantages of thermoelectric cooling, see our white paper.

Are EIC’s products designed to withstand harsh environments?

All of our ThermoTEC coolers are designed for outdoor use and are rated for wash-down (NEMA 4X). Our compressor-based enclosure air-conditioners, air-conditioned electronic/electrical enclosures and air-conditioned transit cases are the ideal solution for housing and cooling electronics – both stationary and mobile – in harsh indoor and outdoor environments.

Can EIC’s Thermotec coolers be used in shipboard applications, salt spray, or corrosive factory environments?

All of EIC’s thermoelectric air conditioners are designed to resist corrosion. All standard units are built from either Type 304 stainless steel or powder-coated aluminum. If additional levels of protection are needed, units can be fabricated from type 316 SS and all aluminum parts can be epoxy coated.

Does EIC have CAD & dimension drawings available?

Yes. All of our drawings are available here for download. We have 3D (STEP), 2D Cad (DWG) and 2D (PDF) dimension drawings for our complete product line including air conditioners, heat exchangers, filter fans, air conditioned enclosures, air conditioned transit cases and optional equipment.

Where can I find installation and operation manuals for EIC’s products?

What is the life expectancy of EIC’s Thermotec coolers?

Due to our solid state design and the use of high quality components you can expect 5 years or more of trouble free operation.

Can EIC’s Thermotec coolers heat as well as cool?

Yes. Every series of our thermoelectric air conditioners offer heating and cooling versions as well as cooling only models.

Can I order EIC’s Thermotec coolers in different voltages?

Yes. EIC’s ThermoTEC thermoelectric coolers are available in a wide range of voltages including 120VAC, 240VAC, 24/28VDC, and 48VDC as well as AC and AC/DC auto-ranging models.

Do EIC Thermotec coolers have UL or other certifications?

Yes, some units have been tested and certified to UL/CSA standards and many units carry the CE mark.

Are any of EIC’s Thermotec coolers approved for use in Explosive Environments?

Our Class 1 Div 2 thermoelectric air conditioners are designed and certified to UL and IEC Standards for use Hazardous Areas.

Can EIC’s Thermotec coolers be painted to match my enclosure?

We offer a wide range of standard colors. Custom paint and powder coating as well as color match are not a problem. Please contact us with your specific color and finish needs for a quote.

My application requires precise temperature control. Can EIC’s Thermotec coolers maintain temperatures in a very small range?

EIC’s thermoelectric coolers come with an adjustable thermostat to control the cooling cycle. The heating cooling units come with a secondary fixed-point thermostat that engages the heating function at approx. 45F and shuts it off at approx. 55F. If precise control is required these thermostats can be replaced with a digital temperature controller. Our DTC-R controller is able to maintain the temperature within your enclosure within +/-1F of a set point (note: requires a heating and cooling thermoelectric unit that is appropriately sized for the application).

How much cooling do I need?
