Gas Cooling Heat Exchangers – HRS G Series

The HRS G Series is a complete stainless steel multitube heat exchanger designed specifically for exhaust gas cooling and thermal recovery applications.

Similar to the HRS K Series, the exhaust gases flow through the interior tubes and the service fluid flows through the surrounding shell. Using our corrugation technology, heat transfer and efficiency are increased over standard smooth tube heat exchangers. In addition, potential fouling is minimized.

Expansion bellows are fitted to absorb the differential expansion between the shell and the inner tubes. Multiple units can be interconnected for larger applications. Options include frame mounting, insulation and stainless steel cladding.

The HRS G Series is suitable for applications such as heat recovery from cogeneration exhaust gases, boiler exhaust gases, industrial exhaust and flue gases.
