Application technology cooling of reactor vessels

Cooling of reactor vessels

Efficient temperature control using cryogenic cooling


The cooling of reaction vessels is achieved using the Cryocontrol® process developed by Messer. Liquid nitrogen is the primary coolant for Cryocontrol units. The energy of evaporating liquid nitrogen is transferred with a special intermediate circuit to the chemical reactor. It is possible to establish and maintain a stable temperature of -100 °C or even below within the reaction chamber.

An electrical heater can be supplied to raise the reactor temperature to plus 60 °C or more, if required. The nitrogen which vaporizes during this cooling process can be fed into a nitrogen gas network and be reused for inerting purposes.

Your advantages at a glance:

  • free choice of temperature in a wide range
  • cooling and heating possible
  • no harmful refrigerants
  • can be used in classificated areas
  • low maintenance costs
  • low operating costs when vaporized nitrogen is used for inerting


Cryocontrol® systems are individually designed according to customer requirements and optimally designed for each individual case. For trials, a mobile pilot plant is available which, together with the appropriate nitrogen supply, can easily be installed at the customer's premises (also in hazardous areas).

The operator has the possibility to determine temperatures or cooling and heating capacities required for his process in practical operation without major investment costs. The results obtained then flow directly into the design for the configuration of a tailor-made Cryocontrol system.
