Forstorage and transport of 30RW units the minimum andmaximum temperatures must not go beyond -20°C and50°C. It is recommended that these temperatures are usedfor transport by container.5.2 - Operating range 30RWNotes 30RW1 Evaporator and condenser ∆T = 5 K2 For 30RW units without hydronic module with an entering condenser watertemperature below 20°C a three-way valve is required to allow operation, whilemaintaining the correct condensing temperature.3 For 30RW units equipped with a hydronic module the minimum entering watertemperature is -15°C.4 Maximum leaving condenser water temperature is 52°C (at full load)A Standard unit with without antifreeze solutionB Standard unit operation with the anti-freeze solution required and controlconfiguration for a leaving water temperature down to 0°C.C Standard unit operation with the anti-freeze solution required and controlconfiguration for a leaving water temperature down to -10°C.D Operation at high air temperature is based on the drycooler selected.E Operation at low air temperature is possible down to -20°C with a drycooler.Condenser leaving water temperature, °CEvaporator leaving water temperature, °CEvaporator leaving water temperature, °CDrycooler entering air temperature, °CC B A52454035302520-10 -5 0 5 10 1550
