HCH/BCH Series

Lodronic™ High-Efficiency, Low-Temperature Horizontal Delivery Hydronic Unit Heater

The Modine Lodronic™ High-Efficiency, Low-Temperature Horizontal Delivery Hydronic Unit Heater is designed to work seamlessly with high-efficiency boilers, geothermal systems, or air-to-water heat pumps. Unlike traditional oversized hydronic heaters that strain boiler systems and diminish performance, the HCH/BCH Series excels in maintaining system balance, reducing electrical load, and providing exceptional discharge air temperatures.

With side supply and return connections and a compact design, these units are ideal for heating buildings with large open spaces, low ceilings, and limited clearances. They are particularly effective at countering heat loss along exterior walls, especially where windows are present. Suitable for warehouses and garages alike, the Lodronic™ delivers unmatched heating efficiency and performance.
