Introducción del producto

This two-row coil uses 3/8 in outside-diameter tubes on a compact pattern with corrugated aluminum fins. It is the shallowest and lowest-water-volume option in this heating-coil group, making it suitable for small terminal or AHU reheat sections. The light core reduces spatial demand, but face size, entering-water temperature and circuit count must still be selected from the actual cleanroom sensible load.

Características clave

Minimal casing depth

Two tube rows reduce the space required in a compact reheat section.

Responsive water circuit

Small tubes and low contained water volume support quick output changes under modulating control.

Standard finned construction

Corrugated aluminum fins increase surface area within a galvanized clean-air casing.

Applications

For small cleanroom reheat terminals, compact AHUs and low-temperature hot-water branches with modest sensible heating loads.

Solutions for Your Application

The shallow coil cannot deliver the required winter output at low water temperature.Rate the actual face size, airflow and entering-water temperature; select more rows when the two-row core lacks surface area.

Small tubes create excessive water pressure drop in a poorly circuited coil.Choose circuit quantity and connection size from the design flow rather than forcing all water through one long path.

Opciones disponibles

Confirm coil face, airflow, water temperatures, circuit count, connection side, fin spacing, casing finish and freeze protection.
