A Waste Heat Recovery Unit (WHRU - ECONOMIZER) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process increasing efficiency.

The WHRU is a tool often involved in cogeneration. Waste heat may be extracted from sources such as hot flue gases from a diesel generator.

WHRU TYPES:

1.  Steam generators for diesel electric power stations our DISEX patented type;

2.  Steam generators for gas turbines our AK/AS type;

3.  WHRU CHP & MARINE.
