I am, looking for a heat interchanger GAs- to air, most efficient, for 400 btu, 100 centigrades output, with stainless steel, for crossing flow, can any one tell me the best design?
The duty you mention is quite small,and I wonder is it 400 Btu/hr or /s,gas flowrate,gas type ,and are you cooling the gas with ambient air..if this is the case ,then a fan coil type heat exchanger will be sufficient..and without solicitng, check with Xchanger Inc (
