To produce a new generation of gas-pumping units and to upgrade the existing ones, the producer needs to update their heat exchange equipment. The aim of the update is to decrease its mass and sizes and to reduce its manufacturing and assembly costs. Heat-hydraulic calculations and experiments with models of the gas-turbine plant cassette-tube airheaters demonstrated that application of profiled U-tubes of a small hydraulic diameter to manufacture the matrices of such heat exchangers provides a high compactness and low metal consumption rate typical for plate heat exchangers. Simplicaty, reliability, elasticity and maintainability which are typical characteristics of tube heat exchangers are retaned.
