Why Choose the nVent HOFFMAN H2OMITTER Thermoelectric Dehumidifier?

The nVent HOFFMAN H2OMITTER Thermoelectric Dehumidifier is a compact condensation management solution designed to remove moisture from the air inside electrical enclosures. Using thermoelectric technology, it helps protect sensitive electronic and electrical components from condensation, corrosion and moisture-related failures in industrial environments.

Part of the nVent HOFFMAN climate control accessories range, the H2OMITTER provides an efficient method of managing enclosure humidity without requiring traditional refrigeration-based cooling systems. Its compact ABS construction and flexible mounting options make it suitable for a wide range of electrical cabinet applications.

Operating from a 24 V DC supply, the H2OMITTER is designed for continuous operation and can remove up to 8 oz of moisture in 24 hours, helping maintain reliable performance of electrical equipment installed in mild steel, aluminium, stainless steel and non-metallic enclosures.
