thermolinePlus plate heat exchangers are characterized by their outstanding efficiency in high-pressure applications with natural coolants such as CO2 and NH3.

With thermolinePlus, thermowave offers you an superior high pressure machine in semi-welded design with an operating pressure of up to 63 bar on the module side.

The variety of our frame designs and connection types are sure to impress in this area. thermolinePlus apparatuses are made from laser-welded modules and can be used for industrial cooling processes requiring low evaporating temperatures.
