Also known as Peltier coolers, these coolers use electrical current to transfer heat away from your enclosure while sealing out contaminants. They cool the enclosure to below the ambient temperature. The solid-state thermoelectric components require no maintenance and take up less space than an air conditioner or heat exchanger.

Rated IP66 and NEMA 4X, these coolers withstand weather, washdowns, and corrosive environments. They meet American and European safety standards.

Coolers without a thermostat run continuously when powered. Add a thermostat, timer, or switch to turn them on and off.

An optional extension bracket holds the cooler away from the enclosure wall for more space inside the enclosure.

Add a drain kit to remove moisture when condensation is likely, such as in humid environments and enclosures exposed to rapid temperature changes. The included hose directs water away from electrical components.

Cool down enclosures, laser and optical equipment, and other small devices to maintain their ideal temperature. An electrical current transfers heat from one side of these modules—also known as Peltier modules—to the other. This means the side closest to your equipment stays cold.

Unlike fans and other coolers, these modules don’t have moving parts that require maintenance. They also don’t rely on moving air for cooling, so you can use them in sealed areas, like refrigerators. Compact, they fit in crowded enclosures and other tight spaces. Their flat sides mean you can attach an adhesive-mount heat sink to draw excess heat away from them.

To control these modules, connect their wire leads to a power source and thermostat or switch. You can even alter them for use in heating applications—just reverse the polarity of the DC voltage to switch their hot and cold sides.

Qmax describes the maximum thermal energy these modules can transfer. Delta Tmax refers to the maximum temperature difference between the hot and cold sides. Change the input voltage to adjust this difference in temperature.
