Commercial brochure Fin & Tube Heat Exchangers LEADING IN THE FIN & TUBE HEAT EXCHANGERS INDUSTRY Heat exchangers are devices largely used in the HVAC&R (Heating, Ventilating, Air Conditioning & Refrigeration) sector in which two fluids at different temperatures exchange energy in the form of heat, without production or consumption of mechanical or electrical energy from the outside. Fluid refers to any substance in the liquid or gas state. Heat is transferred by convection, between the fluids and the corresponding solid surfaces these come into contact with, and by conduction through the wall...
