High Temperature Insulated Heat Recuperators

The IR heat recuperator achieves top heat transfer efficiency by exposing a maximum surface area to the largest possible amount of hot gas. The unit uses a proprietary counterflow design that produces improved heat transfer between two airstreams. Surface exposure is increased by corrugating heat transfer plates to achieve a sinusoidal wave pattern. The plates are spaced 1/2" apart for maximum air flow and minimum pressure drop. This design creates air flow turbulence as the air passes counterflow through the unit, maximizing heat transfer.

As your process air enters the unit, it is directed over the corrugated plates in a counterflow direction to the heated air. Heat from the waste stream is absorbed by the plates and transferred to the cooler airstream... then exits the unit as recovered heat you can reuse or recycle. Airstream temperature can be as high as 1500°F. The unit is equipped with all welded bellows type internal expansion joints of a high-temperature alloy. This allows for the expected growth when operating at high temperatures. Four inches of high-temperature insulation reduces heat loss through the exterior stainless steel casing.

Get the added effectiveness provided by 4" of high-temperature insulation with Exothermics, Inc. Insulated Recuperator. Designed for applications up to 1500°F, the insulated recuperator is constructed from special high-temperature alloys. The all welded assembly protects from airstream cross contamination. The insulation between the inner and outer casing of the unit greatly diminishes heat loss.
