Cryocontrol – Cryogenic Cooling System

Efficient temperature control using cryogenic cooling

Cryogenic cooling - Gas Application

Cryogenic cooling systems are frequently required in reactors for cryogenic cooling to achieve very low process temperatures in the field of state-of-the-art pharmaceuticals and fine chemistry (e.g. in producing active ingredients). They help to steer synthesis steps in the right direction or to increase product output. Temperature requirements as low as -100 °C are not uncommon, with the same process step also usually requiring high process temperatures. The cryogenic cooling system according to the Cryocontrol process from Messer supplies precisely this controlled cooling energy or heat.

This cryo cooling system uses the cooling energy of liquid nitrogen. The principle of the process is simple but efficient: a cryogenic heat exchanger with an intermediate heat transfer medium circuit is interposed between the source of cooling energy, nitrogen, and the reactor. This circuit enables the reactor to be both cooled and heated. In cooling mode the heat transfer circuit is cooled using liquid nitrogen inside the cryogenic heat exchanger. The nitrogen can subsequently be used in gaseous form for other applications, e.g. for inerting. During the cryogenic cooling the low temperature difference between the cooling medium and the product means that the reactor contents are heated and cooled very gently and evenly. This allows the synthesis of temperature-sensitive products.

Your advantages of a cryogenic cooling system at a glance:

  • Free choice of temperature in a wide range
  • Cooling and heating possible
  • No harmful refrigerants
  • Can be used in explosion-hazard areas
  • Low maintenance costs
  • Low operating costs due to double use of nitrogen

How does a cryogenic heat exchanger work?

MESSER-Solution for cryogenic cooling

Cryogenic cooling systems according to the Cryocontrol® process are individually designed 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 cryogenic cooling system.
