TOPAZ NEO range
The TOPAZ NEO adiabatic cooler is a heat exchanger; calories / heat are rejected to atmosphere. The TOPAZ NEO adiabatic cooler is a combination of a dry cooler ith an adiabatic pre-cooling section: this precooling section lowers ambient air temperature by evaporating water which is passed over the cooling / humidifying pads (or Media), specially designed for this purpose.
The fluid is cooled in the dry tube coil by ambient air flow. The ambient air is drawn through the coils by fans mounted centrally on the top of the cooler; the humidifying pads are located in front of the coils are dry. The fan speed is controlled by an inverter depending on heat load to maintain the fluid outlet temperature.
The warm air is then evacuated upwards.
When cooling in dry-mode is not effective and the ambient temperature reaches a predetermined set point, the pads are saturated with water from the sump.
The ambient air is cooled by evaporation when passing through the pads.
This precooled air then passes through the tube coils and cools the fluid.
The water which has not been evaporated on the pads is collected in a stainless steel collector and then flows to the sump. As an option, it can be re-circulated with the make-up water from the sump to be re-distributed over the pads. The water-saving is then significant and does not require water treatment, it is without risk of Legionella.
