High-Output Mobile Evaporative Air Coolers
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.
Replacement pads are sold separately.

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. 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.

Cooling Bandanas
Soak these bandanas before wearing them—they’ll cool you off as the water evaporates.
Cotton bandanas contain absorbent cooling crystals to hold large amounts of water. Soak in cold water for 20 minutes for all-day cooling.
Run polyester/spandex bandanas under cold water and wring them out for instant cooling that lasts up to three hours. With UPF 50 sun protection, they protect your skin from UV rays when working outside. An odor-resistant finish prevents bacteria growth, eliminating odors caused by sweat. Reflective accents call attention to the wearer in low-light conditions, helping keep them safe. They have a low profile so they’re easily worn under hard hats. The polyester/spandex fabric is durable for long-term use while remaining soft and comfortable. It’s breathable to keep you cool, and easy to breathe through when used as a face covering. These bandanas are moisture wicking when dry, helping keep sweat out of your eyes when worn as a headband. High visibility bandanas come in neon colors, helping prevent accidents by making wearers easy to spot.

Cooling Vests
Chill these vests to keep you cool and comfortable in hot conditions.
Style A are lightweight nylon. Soak in cold water for 5 minutes, and it keeps you cool through evaporation for up to 4 hours. The exterior is water resistant to keep you dry. They have a zipper down the front.
Style B have cooling packs that maintain a consistent cool temperature of 55° F for up to 3 1/2 hours. Soak the packs in ice water for 10-15 minutes, or store in the freezer for at least 20 minutes before wearing. These vests are durable cotton for better abrasion resistance than Style A. They have hook and loop fasteners at the shoulders and around the waist to modify the fit and tear away easily if caught on machinery.

Hot and Cold Packs
Cold and Hot Packs—Squeeze to break the inner bag for instant activation.
Reusable Hot/Cold Pack—For cold, freeze for one hour. For heat, microwave for 50 seconds or place in boiling water for two minutes.
Ice Packs
Durable and reusable, these packs are less messy and keep contents colder longer than ice. Often used with beverages and food, they keep things cold but not frozen. All flex to wrap around objects and fit into tight spaces. The packs consist of smaller cubes that can be cut apart and used individually.
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.
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.
