nVent Hoffman Thermoelectric Coolers
The nVent Hoffman thermoelectric coolers deliver solid-state cooling through the use of high efficiency Peltier modules. Designed for electrical and electronic enclosure cooling where reliable, compact performance is required, they are available in a wide range of cooling capacities for smaller and moderate enclosure requirements. Because they utilize solid-state heat pump modules, nVent Hoffman thermoelectric enclosure coolers deliver cooling with no moving parts creating vibrations, no circulating refrigerant, and no air exchange with the enclosure and the external ambient. This makes them ideal for many types of electronics enclosures including industrial automation, controls, analyzers, telecom radio systems, and other types of panels.
Thermoelectric enclosure coolers from nVent Hoffman do not utilize an internal fan to circulate air inside of the enclosure, instead depending on natural convection for heat dissipation. This allows them to be used in harsh or vibration-prone applications where maintaining environmental protection ratings and long term reliability are especially important. They operate on 24V or 48V DC input for compact panel mounting directly on the enclosure wall or door. Hoffman thermoelectric coolers are engineered to properly integrate with Hoffman electrical enclosures, and support typical electrical enclosure protection ratings (NEMA, IP) when installed correctly.
FAQs
What is a thermoelectric cooler used for in enclosures?
A thermoelectric cooler is used to regulate enclosure temperature using solid-state Peltier technology, protecting sensitive electrical and electronic components from heat without compressors or refrigerants.
When should I choose a thermoelectric cooler instead of an enclosure air conditioner?
Thermoelectric coolers are best for smaller enclosures, lower heat loads, and applications requiring quiet operation, low maintenance, and high reliability where traditional air conditioning may be excessive.
Do nVent Hoffman thermoelectric coolers require maintenance?
Minimal maintenance is required because thermoelectric coolers have no moving parts or refrigerants, making them highly reliable and well suited for industrial environments.
Do Hoffman thermoelectric coolers maintain NEMA ratings?
Yes, when installed correctly, nVent Hoffman thermoelectric coolers are designed to help maintain the enclosure’s original NEMA and IP protection ratings.
Are nVent Hoffman thermoelectric coolers suitable for outdoor applications?
Yes, many Hoffman thermoelectric coolers are suitable for outdoor and industrial use, providing dependable cooling in environments exposed to dust, moisture, and temperature fluctuations.
