Technical Examples

A refrigeration-based compressed-gas dryer comprises a group of heat exchangers (10), this group of heat-exchangers including a gas-to-gas heat exchanger (20), an evaporator (30), a condensate separator (50) and at least a refrigerating circuit (40), wherein in said gas-to-gas heat exchanger (20) there is provided a pre-cooling section (22), where heat is exchanged between a mixture of compressed gases to be dried entering said group of heat exchangers (10), and a heating section (24) for a mixture of dried gases exiting a condensate separator (50), wherein in said evaporator (30) there is provided a cooling section (32), where heat is exchanged between said mixture of compressed gases to be dried exiting the gas-to-gas heat exchanger (20), and an evaporating section (34) for a refrigerant medium, where said mixture of compressed gases is cooled down to a desired dew point. According to the present invention, said group of heat exchangers (10) comprises a set of finned or embossed plates (21, 31, 33), which are stacked and joined with each other so as to be adapted to create a number of passages for the counter-current flow and/or cross flow and/or mixed flow of said gases, wherein said group of heat exchangers is provided as a unitary piece.
