Notes
1 30RW/30RWA units can operate from 4°C to 0°C without modification.
In all cases the units must be configured for low leaving-water temperature,
and use of antifreeze is required.
2 30RW units without hydronic module operating below 20°C entering
condenser water temperature require the use of a three-way valve controlled
from the 0-10 V analogue output of the Pro-Dialog control.
3 For a flow rate corresponding to a condenser Δt of 5 K.
4 The maximum entering air temperature is based on the drycooler selection.
5 The minimum entering air temperature range is between 15 and 20°C (without
the use of three-way valves)
Operation at -15°C ambient temperature is possible with the use of a three-
way valve to maintain the required minimum condensing temperature (see
note 2).
6 The maximum entering air temperature is based on the remote condenser
selection.
IMPORTANT: Maximum ambient temperatures. For
storage and transport of 30RW units the minimum and
maximum temperatures must not go beyond -20°C and
50°C. It is recommended that these temperatures are used
for transport by container.
5.2 - Operating range 30RW
Notes 30RW
1 Evaporator and condenser ∆T = 5 K
2 For 30RW units without hydronic module with an entering condenser water
temperature below 20°C a three-way valve is required to allow operation, while
maintaining the correct condensing temperature.
3 For 30RW units equipped with a hydronic module the minimum entering water
temperature is -15°C.
4 Maximum leaving condenser water temperature is 52°C (at full load)
A Standard unit with without antifreeze solution
B Standard unit operation with the anti-freeze solution required and control
configuration for a leaving water temperature down to 0°C.
C Standard unit operation with the anti-freeze solution required and control
configuration 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.
