Models HE1XV and HE1XH are commercial energy recovery ventilators (ERVs). According to the manufacturer, the units have pull-through blowers so MERV-8 rated filters protect both the ERV core and the blowers. The company says the ERVs have easy-access split doors and an upgraded collar design with flex duct retention rib. The HE1X Models now are available with a 277-V, single-phase option, in addition to single- and three-phase multivoltage models. Both unit models can be incorporated into the same circuitry to provide preconditioned temperature and humidity with the same distributed design principles used for a wide variety of terminal units or fancoils, the manufacturer states.
