The TOPAZ adiabatic cooler is a combination of dry cooler with an adiabatic precooling section: this precooling section lowers ambient air temperature by evaporating water which is passed over the cooling / humidifying pads, 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 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. The collected water is re-circulated in the process and distributed over the pads again. The water saving is then significant and does not require water treatment, it is without any bacteriological risk.
The TOPAZ range is robust due to its design and choice of materials, and specially developed for both urban and industrial environments.
Your benefit:
- No water treatment required
- No water spray in airflow
- Elimination of legionella risk
- Very low water consumption
- Permanent magnet motors (efficiency better IE3)
- Low operating costs
- Easy maintenance due to vertical H shape of the tube coils : full access through the central door
