Additional information


HUH2 of heat-exchanger unit heaters is designed for rugged industrial applications in steam, hot water, glycol or other fluid circulating heating systems. HUH2 is designed for pressures and temperatures up to 400 psi and 550 °F respectively in single-pass and multi-pass core configurations with multi-pass units greatly improving performance characteristics when used with liquids. An additional benefit is our reversible core connection feature that allows you to reverse the configuration of the inlet and outlet connection locations, by rotating the core, to suit your installation.

HUH2 heaters meet ASME requirements with various CRNs and are suitable for a wide variety of heating fluids and are perfect for steam, hot water, or glycol applications. They are also used with other non-lethal or non-poisonous fluids (as defined by ASME) for both space heating and liquid cooling applications that include but are not limited to hot-oil heaters, lube-oil coolers, product process coolers, pump-seal coolers, etc.  Heaters are available with either General Purpose or Explosion-proof electric motors.
