Specifications

Applications

The HE-Z Series is the flagship Hi-Velocity SDHV air handler — ideal for retrofits, historic homes, custom builds, high-end multi-family and commercial fit-outs where conventional ductwork won't fit or where zoning, dehumidification and superior air filtration are required. Its VFD-driven pressure-controlled fan supports two-stage heating and cooling, constant fan, economizer operation and heat-pump back-up in a single factory-assembled unit.
