Cain Industries manufactures exhaust heat exchangers and steam generators for gas and diesel engines, gas turbines, microturbine generators and fuel cells. Captured BTU is transferred back into a desired water, glycol, thermal fluid or steam production heat sink. Suitable fuel types for combustion sources include natural gas, propane, biogas, digester gas, landfill gas, diesel fuel and light to heavy fuel oils. Tremendous savings result from overall system efficiency improvements when recovered energy is repurposed within the facility and processes.
