I am working on an industrial scrubber, which is operated by a three speed 0.97L diesel engine. The scrubber is made of rotomolded parts which are very sensitive to heat. Since the exhaust temperature of the engine is around 1200 deg F it is melting the rotomolded components (chassis) around it. Currently heat wraps are used to insulate the exhaust pipe but they are very expensive( over $600). We cannot use EGR as it is against the regulations. Is there a solution to bring down or safely dissipate the exhaust heat without damaging the plastic around it. Thanks!
