These heat exchangers are designed to remove thermal energy from the exhaust gas of natural gas, diesel and bio-fuel engines and transfer it to the water circuit. The extracted heat can be used for space heating, domestic hot water and industrial process that requires hot water.
Enable waste heat recovery, and can be used on Cogeneration/Combined Heat and Power (CHP) equipment up to 1 MW.
Features and Benefits
Constructed with stainless steel tubes, tube plates and body and cast iron end covers which allows use with Biogas, Diesel Gases and Natural Gases.
Suitable for engines up to 1MW.
Suitable for use with engines powered by conventional and alternative fuels
Fully welded stainless steel construction for reliability and durability
Can also be used to extract energy from gas or air and transfer it to the water circuit
Compact and highly efficient design for ease of installation.
Ideal to reduce the exit temperature of the exhaust gases in hazardous areas
Used in conjunction with jacket water, charge air, fuel and oil coolers, Bowman units can reclaim up to 60% of waste heat from an engine
Bowman units when fitted provide FREE HEATING & HOT WATER
Manufactured to a standard range of sizes, to meet your needs
