BIH designs are robust and efficient with high rates of availability and reliability operating in critical service at elevated temperatures 24/7. Our equipment is designed for minimum intervention and there are many examples of our units in operation well in excess of their anticipated design life.

BIH WHRUs are providing reliable service around the globe in LNG plants, gas plants, FPSOs, ORC (Organic Rankine Cycle) systems and Offshore Platforms. Our bespoke designs range in size, shape and orientation, and our designers are able to select from a large toolbox of solutions to find the best fit for every application.

We are continually expanding our design portfolio and have a range of patented novel design features which enhance the performance and operability of the units. The BIH compact design is ideal for offshore environments or onshore plants where space is a constraint, such as expanding an existing plant, replacement of an existing unit or retrofit of a WHRU onto a simple-cycle Gas Turbine.
