The filter preheaters of FW 620 type combine heat exchangers with filtering cartridges and are designed to be used for heating and filtering natural gas. and other non-corrosive gases. The working principle consists of heat transfer from a hot fluid (heat transfer fluid) to the gas to be heatid and gas filtration.
