Thermoelectric Enclosure Coolers

Thermoelectric enclosure coolers, also known as thermoelectric air conditioners, are a type of cooling technology that uses the Peltier effect to transfer heat away from an enclosure or a small space. The Peltier effect is a phenomenon in which an electric current is passed through two dissimilar materials, causing a temperature difference between them. When properly configured, this temperature difference can be used to transfer heat from one side of the device to the other.
In thermoelectric coolers, the Peltier device is typically installed inside the enclosure or the small space that needs to be cooled. When an electric current is passed through the Peltier device, one side of the device becomes cooler while the other side becomes warmer. By placing the cooler side of the device inside the enclosure or the small space, heat is transferred away from the space and dissipated to the environment through a heat sink or a fan.
Thermoelectric coolers have several advantages over traditional compressor-based cooling systems. They are generally more energy-efficient, more compact, and quieter. They also have no moving parts, which means they require less maintenance and are less prone to mechanical failure.

More Information about Thermoelectric Coolers
Hoffman Thermoelectric Indoor/Outdoor Coolers have cooling capacities from 204 to 682 BTU/hour and remove heat around critical components within an enclosure. The low-profile, compact coolers use the Peltier effect to cool small indoor and outdoor enclosures and have a small footprint with DC powered operation, which is ideal for telecomm applications. The coolers are a low-maintenance, reliable solution with no compressors, condensers or filters required.
FAQs
What is closed loop cooling?
Closed-loop cooling is a type of cooling system that circulates a liquid coolant through a closed system to absorb heat from a heat source and dissipate it to the environment. The coolant is continuously circulated through the system in a loop, hence the name "closed-loop."
Common modifications or accessories that are used to enhance electrical cabinets.
Lighting kits. Lighting kits are often used in outdoor applications. There are many different styles of lighting kits that can be used, but LEDs have become the preferred lighting solution in the past several years.
Pressure switches. Pressure switches operate on a spring and react to the cabinet door opening and closing. They can be used for lights, intrusions alarms and exhaust fans.
Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.
Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.
Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.
Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.
Locking mechanisms. Locking mechanisms are used to secure cabinets.
Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
