Hi-Velocity VESH-650-15 kW Elec. Str. Htr. Electric Strip Heater

The VESH-650-15 kW Elec. Str. Htr. is a 15 kW electric strip heater from the VESH-650 family — a variable-zoning strip module for use with Hi-Velocity zoning-capable air handlers. Unlike the standard 2-stage ESH, the VESH is SCR-controlled and modulates output to match individual zone calls in a multi-zone system.

Key features

• SCR (Silicon-Controlled-Rectifier) controls for infinite-position modulation across zones
• Designed for use with WEG-zoning-capable HE-Z, LV-Z or HE-P air handlers
• Automatic-reset thermal cut-out safety discs
• Front-panel-accessible high-voltage wiring diagram
• Slides into the BU (blower-unit) air handler on the supply side

Specifications

Applications

The VESH is specified when the design has more than 2 zones or requires modulated output matching to variable zone loads. Standard 2-stage requirements are better served by the lower-cost ESH module of the same size and kW rating.
