REFRIGERATION SYSTEM:
The refrigeration system is a medium temperature system with a range from 35
°
F to
70
°
F. This is the most efficient range. If temperatures below or above this range are
required, they should be discussed with our engineering department. The refrigeration
system also includes a hermetically sealed refrigeration system and all parts, except the
evaporator coil, are standard to the refrigeration industry. The evaporator coil is installed
in a stainless steel tank and the tank on each unit has a large area. This large area
allows better control of water temperature and causes the water flow not to be
restricted, resulting in better water circulation. Any repairs to the refrigeration system
should be done by a qualified refrigeration company. Schreiber Engineering will always
have a service engineer available to answer any questions regarding chiller service.
This unit has a service valve on the suction and discharge line. The suction line has its
valve on the suction line. The high pressure or discharge service line is on the receiver.
This unit is charged with R-22.
DO NOT OVERCHARGE
because this will cause
damage to the compressor. The refrigeration sight glass is fuzzy until the unit reaches
its proper temperature.
MAINTAINING THE CHILLER:
Very little maintenance is required on this unit. It might be necessary to clean out the
heat exchanger located within the water tank, only depending on the condition of the
water used in the chilled water circuit. It might also be necessary to blow out the
condenser from time to time, depending on the environment of the installed unit. Finally,
the water-cooled condenser needs to be flushed out once in a while. The frequency of
this process depends on the condition of the condenser's water supply.
