Chem engineers have been designing Steam Jet Thermocompressors since decades and each unit is designed specifically to suit a customer's process and mechanical requirements to ensure maximum operating efficiency.

Thermal Vapour Recompressors, also known as Thermocompressors are used for the suction of low pressure fluids and their compression to an intermediate reusable pressure. Since this recompressed fluid can be used for another process, energy can be saved. Thermocompressors are finding increased applications in Paper, Food, Pharmaceutical, Chemical and other Process Industries in Steam Dryers, Vacuum Dryers, Evaporators, Deodorizers, etc.

A Steam Jet Thermocompressor is an energy saving device that compresses low pressure steam, often waste steam, to a higher usable pressure.

For applications with varying operating conditions, Chem offers a variable nozzle design to ensure efficient performance is maintained over the range of desired operation. To achieve variable performance, a steam regulating spindle is fitted to the nozzle and actuated either manually or automatically.

Construction of Thermocompressors


Chem Thermocompressors are simple and consist of three fundamental components : Motive Steam Nozzle, Suction Body and a Diffuser.

A wide range of materials of construction are available including Stainless Steels, Carbon Steel, Chrome Molybdenum, Titanium, etc.

Steam Jet Thermocompressor designs are available for all National and International Design Codes such as ASME VIII Div.1, PD 5500, Stoomwezen, A.D. Merkblatter, etc. Units can be provided with CE marking where required.
