Explosion-proof liquid cooler (chiller) type FKS-KWS
The BARTEC BENKE explosion-proof closed-circuit liquid chiller type FKS-KWS consists of a highly efficient air-cooled condenser combined with a hermetically sealed compressor and is suitable for installation in Zone 1 explosive gas environments. The electrical control system is supplied with its own Ex d enclosure. Optionally, with the BARTEC BENKE analyser, the control system can be placed inside the Ex p housing of the analyser itself.
In any enterprise, laboratories that use analysers, laboratory equipment, measuring instruments, sensors.
As a rule, a process cooling water supply is necessary for their correct operation.
In most cases, the parameters of centrally supplied process water have a large differential of values, which negatively affects the accuracy of measurement and stability of equipment operation. Also, do not ignore the possibility of a failure of the general circuit and as a consequence, deviations in the operation of many devices.
The use of localised circulating liquid coolers completely solves all of the above problems.
