nVent Hoffman Enclosure Heat Exchangers
nVent Hoffman enclosure heat exchangers are designed to manage heat generated by electrical and electronic equipment while protecting sensitive components from harsh environments. Available in air-to-air and air-to-water configurations, these heat exchangers use closed-loop cooling systems that recirculate internal enclosure air without introducing outside contaminants such as dust, moisture, or corrosive elements. Many models are rated for NEMA Type 4 or Type 12 protection, making them suitable for a wide range of industrial applications.
Air-to-air heat exchangers rely on convection cooling using sealed copper heat pipes surrounded by extruded aluminum fins. Heat generated inside the enclosure causes the liquid within the copper pipes to vaporize and migrate to the cooler external side of the exchanger. There, heat is dissipated into the ambient air, and the vapor condenses back into liquid to repeat the cycle. This continuous process efficiently removes heat while maintaining enclosure integrity.
Air-to-water heat exchangers operate on the same temperature differential principle but transfer heat by forcing enclosure air across water-cooled coils. These systems are ideal for applications where a cooled water supply is available and where precise temperature control is required. nVent Hoffman air-to-water models are engineered for dependable thermal performance and include features such as condensation management systems to support reliable long-term operation.
FAQs
Q: What is the benefit of a closed-loop enclosure heat exchanger?
Closed-loop heat exchangers cool internal enclosure air without allowing external air to enter, helping protect electrical components from dust, moisture, and corrosive environments.
Q: What is the difference between air-to-air and air-to-water heat exchangers?
Air-to-air heat exchangers transfer heat from the enclosure to the surrounding air using heat pipes and fins, while air-to-water models remove heat by passing enclosure air over water-cooled coils.
Q: What NEMA ratings are available for nVent Hoffman heat exchangers?
Many nVent Hoffman enclosure heat exchangers are available with NEMA Type 4 or Type 12 ratings, depending on the model and intended environment.
Q: Are air-to-water heat exchangers suitable for outdoor use?
Air-to-water heat exchangers are typically used in indoor or controlled environments where a reliable cooled water source is available. Model specifications should be reviewed for environmental suitability.
Q: What mounting options are available?
nVent Hoffman heat exchangers can be surface-mounted or recess-mounted, allowing flexibility based on enclosure design and installation requirements.
