Hi-Velocity HE-B-51-H-220v Air Handler
The HE-B-51-H-220v is the 220V HE-B-51 — the Builders Series variant of the HE-Z SDHV fan-coil, engineered for multi-unit residential applications. Same VFD motor, PSB or HEB circuit board and WEG controls as the standard HE-Z line, but with a galvanized cabinet for cost-optimized multi-family jobs. Factory approval required for order acceptance.

Applications
Builders Series HE-B is used exclusively on multi-unit residential builds. It delivers the Hi-Velocity SDHV performance profile — pressurized small-diameter ducts, constant air circulation, superior humidity control — at a lower per-unit cost via the galvanized cabinet. The zoning-capable models (HE-B-50/70/100) accept the WEG zoning kit; the -51/-71/-101/-52 variants ship with the non-zoning HEB board. Factory acceptance required.
