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.

Send cool water to equipment right from your bench top without compromising precision. These chillers maintain constant, uniform temperatures within 0.2° F where other chillers only keep liquid cool within a few full degrees. This makes them ideal for equipment where small temperature changes could cause an issue, such as microscope cooling plates.

Fill these chillers with water or glycol solutions, and an internal pump moves the liquid through a cooling system and out to your equipment. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, alerts, and other information from the LED display.

Chillers rated for 500 Btu/hr. are also known as Peltier chillers. They cool liquid using electricity—no need for compressors or refrigerants. Because they don’t use a compressor, you’ll hardly hear them when they’re on. To check fluid levels at a glance, their tank inlet is semi-clear.

Save floor space—these chillers mount to standard 19" electronics racks, enclosures, and cabinets. Because they're so compact, you can even fit multiple chillers on the same rack. Where other chillers only keep liquid cool within a few full degrees, these chillers are highly precise, maintaining constant, uniform temperatures within 0.18° F. This makes them ideal for equipment where small temperature changes could cause an issue for your process. Also called Peltier chillers, they cool using only electricity, so there's no compressors or refrigerants. Without a compressor, you'll hardly hear them when they're running.

Fill these chillers with water or glycol solutions, and an internal pump moves the liquid through a cooling system and out to your equipment. There are multiple ways to control these chillers. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, pressure, and flow rate from the digital display. It will also display maintenance reminders and alarms.

A port on the front lets you quickly check fluid levels and fill the chiller with fluid without removing it from the rack or disconnecting it from your system.
