(1) For low-temperature applications, where the leaving water temperature is
below 3.3°C, a frost protection solution must be used. Please refer to option 5
and option 6.
(2) For lower condenser temperatures a water flow control valve must be used at
the condenser (two or three-way valve). Please refer to option 152 to ensure
the correct condensing temperature.
Note: Ambient temperatures: During storage and transport of the 30XW units
(including by container) the minimum and maximum permissible temperatures are
-20°C and 72°C (and 65°C for option 200).

10 - MEDIUM TEMPERATURE (OPTION 5) AND LOW TEMPERATURE (OPTION 6) GLYCOL SOLUTION OPTIONS

Units with the medium temperature (option 5) or low
temperature (option 6) option allow glycol solution
production down to:
• - 6°C with ethylene glycol and option 5 (minimum
weight concentration of 25%)
• - 3°C with propylene glycol and option 5 (minimum
weight concentration of 24%)
• - 12°C with ethylene glycol and option 6 (minimum
weight concentration of 35%)
• - 8°C with propylene glycol and option 6 (minimum
weight concentration of 30%)
