High-efficiency stainless-steel condensate recovery units


Amarinth’s range of smaller condensate recovery units (CRUs) is optimized for light industrial use to complement its existing range of heavy-duty intelligent CRUs. The smaller CRUs are manufactured from stainless steel instead of the more traditional galvanized steel, but cost the same as the existing products. An effective CRU is a proven way to reduce energy costs, collecting hot condensate from the steam system and returning it back to the boiler plant to be used as boiler feed. Using innovative technology, the smaller, lighter CRUs return condensate back to the system more frequently.

High-efficiency, multistage motors, along with motor design and control system improvements, allow the CRUs to cycle on/off by an increased factor of four over traditional designs. The new motors and control systems have also enabled Amarinth to rationalize the range to just three units, making the CRU selection process easier. The units are available immediately in simplex or duplex stainless steel to suit the application. Amarinth Ltd.
