Circuit Board Thermal Interface Pads

These heat-dissipating pads pull heat away from electronic components. They’re often used to fill gaps between two surfaces that require thermal contact. All meet UL 94 V-0 for flame retardance.

Thermoelectric Modules

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.

Maximum Power Transferred (Qmax) @ Temperature—Qmax describes the maximum thermal energy these modules can transfer.

Maximum Temperature Drop (ΔTmax) @ Heat Sink Temperature—Delta Tmax refers to the maximum temperature difference between the hot and cold sides. Change the input voltage to adjust this difference in temperature.

Produce twice as much cool air as standard mobile evaporative air coolers. Also known as swamp coolers, use these air coolers wherever air conditioning is impractical. They take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air.

Cooling Hard Hats


	Cooling Thermal Barrier

Ratchet Adjustment

Stay cool and protect your head—a reflective barrier in these hard hats lowers the temperature by 20 degrees. A full brim runs around the hat to shield your head and neck from sun, rain, and glare. It offers 12% more coverage than the brim on a standard full brim hat, providing additional protection from the elements. A built-in sweatband keeps perspiration out of your eyes, even if you sweat.

Type I hard hats protect against blows to the top of the head only. A foam shell absorbs impact, reducing force on the neck and head. To fit the hard hat snugly to your head, turn a knob on the back that tightens the suspension. The reversible suspension lets you turn the hat around without taking it off. For example, spin the hat to move a face shield out of the way or turn the hat to fit in a tight space. You can also add attachments such as face shields or earmuffs to the mounting slots on the hat.

C—Class C hard hats have not been tested for electrical protection.

E—Class E hard hats insulate from electrical shocks and are often used near overhead power lines and high-voltage equipment. They’re tested at 20,000 volts.

Ventilation Holes—Hard hats with ventilation holes add another way to stay cool by letting air circulate.

Mobile Evaporative Air Coolers


	NEMA 5-15

Also known as swamp coolers, use these air coolers wherever air conditioning is impractical. They take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air. These air coolers have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. All have a NEMA 5-15 plug, which is a standard three-prong plug.
