Evaporative coolers differ from evaporative towers in that they use a heat exchange coil for the primary process fluid.

WHAT DOES THIS MEAN?

Having a machine with the process fluid inside a heat exchange coil allows the primary fluid not to be “dirtied” by sediments or microparticles present in the water. The presence of the heat exchange coil also makes it possible to use glycolised process water where the system requires it.
Key points for choosing an evaporative cooler instead of an evaporative tower:

The process fluid flows through a heat exchanger coil: the fluid is not contaminated by particles in the water or by atmospheric agents.

Glycolised fluids can be used safely thanks to the use of the heat exchange coil.

The units can operate in dry mode in sub-zero winter conditions, without recirculating water and only with the fans running.

RAA

The axial version of evaporative coolers replaces evaporative towers where it is necessary to separate the process fluid from the atmosphere and recirculating water. The units are similar to evaporative towers, although they have a reinforced structure to support the weight of the coils and have an on-board recirculation pump.

RAP

As with the series of evaporative towers of similar design, the pre-fan coolers have higher efficiency and simplified maintenance due to the positioning of the motor and fan.

RC

Centrifugal fan evaporative coolers are a classic solution for installations in areas where a defined noise levelmust be met and a primary process fluid must not come into contact with the atmosphere. W-tech centrifugal fan coolers can be fitted withinlet and outlet silencers, further reducing the noise emission of the unit.

RCR

Low height closed circuit coolers with centrifugal fans are the best solution where space is limited, especially in height. They are often designed with a vertical air intake where the installation is in a well. They are often designed with a vertical air intake where the installation is in a well.
