NVENT HOFFMAN H2OMITTER Thermoelectric Dehumidifier
nVent HOFFMAN H2OMITTER thermoelectric dehumidifier designed to remove moisture from electrical enclosures and protect internal components from condensation.
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.
