5.6 Special equipment: water cooling system
Centrifuges with water cooling are equipped with a special refrigeration unit
with a refrigerant (CFC-free), modified electronic system, and a special
software version. The housing of the GMP version is completely closed. All
of the other units have vent slots for the motor and electronic power
system.
Operating conditions
• The centrifuge must only be operated with media-neutral water of
drinking water quality (hardness <8) or with another suitable refrigerant.
We recommend using a filter (to be provided by the customer).
• The operating pressure of the water must be between 1.5 and 5 bar.
We recommend using a pressure reducer (to be provided by the
customer).
• The maximum flow rate depends on the operating conditions (e.g.
speed and rotor temperature). The minimum cooling water consumption
at maximum power is approximately 5 l/min.
At a standstill, the water supply is stopped by a solenoid valve. In the
case of the GMP version, the valve is opened in two steps:
1. reduced flow, only for the internal air cooler
2. unlimited flow, when the compressors are running.
• The maximum temperature at the water inlet is 20°C. The lower the
water temperature, the more efficient the cooling.
• The centrifuge is equipped with a ¾-inch water connector .

cooling water inlet

cooling water outlet
