Introducción del producto

The four-row half-inch coil doubles the tube depth of the terminal reheat version and accepts half- or full-circuit water arrangements. It provides higher sensible recovery after a deep cooling or dehumidification stage while remaining smaller than the six-row large-tube option. Galvanized or stainless casing allows the core to be matched to dry or moisture-prone AHU sections.

Características clave

Higher sensible recovery

Four tube rows add surface area for central AHU reheat after low-temperature cooling.

Circuit selection

Half- and full-circuit options balance water velocity, pressure loss and control range.

Wet-area casing option

Stainless construction can be selected when the reheat coil sits close to a condensate-producing section.

Applications

For cleanroom AHU reheat after deep cooling, dehumidification or low-dew-point make-up-air treatment.

Solutions for Your Application

Water velocity is too low in a full circuit and air collects in upper tubes.Select half circuit where needed, provide an accessible vent and balance flow at design and minimum load.

The reheat coil remains wet from upstream carryover and corrodes the casing.Control wet-coil velocity, provide separation distance and choose stainless casing for persistent moisture exposure.
