2.13. Pump
The chiller's pump ensures the necessary circulation of the cold water. This is drawn out of the
chiller's internal tank and is pumped through the process circuit. The units can also be supplied
optionally as continuous flow coolers without tank, with pump or without tank and without pump
(see
Chapter 3.1 Version without tank, with pump and Chapter 3.2 Version without tank, without
pump ).
2.14. Fan
The fan draws the cooling air from the surroundings through the condenser and blows the heated
air upwards and out of the refrigeration machine (chiller). To prevent injuries the fan is secured
against accidental touch by means of protective grilles on the discharge side. The fan's speed is
variable and is controlled by the main circuit board. The speed of the fan is essentially determined
by the condensation pressure.
2.15. Cold water circuit
The cold water is drawn out of the internal tank of the chiller by the internal pump and is pumped
through the process circuit. The units can also be supplied optionally as continuous flow coolers
without tank, with pump or without tank and without pump (see
Chapter 3.1 Version without tank,
with pump and Chapter 3.2 Version without tank, without pump ). In the process circuit the cold
water absorbs heat. The circuit closes when the cold water is pumped back into the chiller. It flows
through the evaporator in which it gives off heat. The cold water then returns to the tank. The cycle
begins again.
