Airbatic Version
Airbatic operation, thanks to the water blast sprayed on the
condenser coils, offers the following benefits.
- The chilled water at the outlet can be at a temperature
that is below ambient temperature;
- High cooling capacity in compact dimensions.;
- Low water consumption compared to cooling towers;
- Radical energy savings when cooling condensation water
for water-cooled chillers;
- High cooling power is presence of high ambient
temperatures;
- High cooling efficiency also in low noise operating mode.

- Nominal conditions : delta of 10°C between the inlet
water temperature and the ambient temperature, delta t of 5°C
between the inlet water temperature and the outlet water
temperature from the water cooler at sea level and 0% of
glycol.
- Sound pressure level in free field at a 10 m distance
from the unit at air/refrigerant beat exchanger and at 1.2 m
from the ground.
- The RWD 020 model is available with 400 ± 10% 3/50
electric supply.
RWD
Air Cooled water coolers
RWD units are packaged units to cool a flow of water utilizing
ambient air. The water flows in the tubes of a fined core heat
exchanger. A series of fan units generate an air stream that
flows over the external finned surfaces of the heat exchanger
thereby cooling the water flow inside the exchanger pipes.
When ambient temperature is lower than the water temperature
required by the suer service, RWD, coolers constitute the
optimum cooling solution.
Standard Features
- Single or double coil depending on the model.
- Air vent valve and drain connection on each coil ) from
030 to 350)
- Fan Motors with overheating protection · IP 54
protection rating
- Metal mesh filters on coils
- Electronic controller kit with remote installation
facility (models from 030 to 350)
- Axial fans with step type speed control (from 075 to 350)
Energy Saving
With a specific kit RWD water coolers can be easily connected
to pre- installed water chillers or newly installed units. This
solution is ideal for areas where the ambient air temperature is
lower than the required temperature of the process water to the
cooled for most of the year.
In this situation the RWD solution allows the use of "
free cooling" mode.
The use of RWD coolers leads to significant energy savings
resulting in highly attractive returns on initial investments
