2-8. DE-ICING AND CLEANING
WATER DRAINAGE A floor trench, located in front of the door is recommended, with a
floor drain nearby, because of the quantity of water used in
cleaning.
For sanitary reasons, do not install a drain in the floor of the
blast chiller.
To ensure proper performance:
• When sizing a single condensing system for multiple blast chill-
ers, the total BTU’s of all blast chillers should be considered
• An evaporator pressure regulator is required for combinations of
freezers and chillers on the same system
• Do not install a single condensing unit for more than 1 blast
freezer if they are to operate simultaneously; always install
separate condensing units for each blast freezer
• In addition to the compressor, condenser, and receiver, the unit
should be fitted with:
- low ambiant control
- high pressure, pressure controller
- automatic pump-down controller
- drier
- sight glass
- line
- insulation and refrigeration load
• Depending upon the ratings, the installation of a separate oil
separator, liquid valve, suction trap, etc, is also recommended
• Remote condensing unit compressors for blast chillers can be of
any type, but blast freezers, or blast chiller/freezers must use
semi-hermetic compressors, not hermetic
• Local area climate and codes help in detemining the size of the
condensing unit; use the maximum average temperature of the
summer, not the hottest temperature, or the unit will be over-
sized and over-priced for only a couple of weeks of hot
weather
• The condensing unit should have a separate electrical line
protected by a fuse or circuit breaker of the proper rating
