For decades, closed-circuit water cooling towers were built by Caravela - Thermotank, and others, with systems of steel tubes, copper, etc., installed inside the tower, in an attempt to eliminate the external heat exchanger, tube-like belongings, etc. Many know this type of device as an evaporative condenser.
This type of device has one deadly disadvantage. During its operation, the tubes placed inside the tower clog from the outside, making it almost impossible to remove the encrusted salt, with the natural loss of capacity. Given the need for a closed-circuit tower, without the above-mentioned operation problems, we developed the SF cooling tower system. The system consists of a stainless steel plate heat exchanger, 1 cooling tower connected by pumps and belongings. The heat exchanger allows for easy operation and maintenance.
The evaporative cooling system applied is counter-current. Atmospheric air is drawn in through suitable windows, installed at the base of the cooling tower, and forced against the current, the water to be cooled, which has been injected, hot, at the top of the cooling tower. After this process, the water is collected in the pool and pumped back to the equipment to be cooled, closing the circuit.
SF cooling towers are the smartest way to cool your process. For capacity from 35m3/h to 525m3/h per cell.
Working principle of the Cooling Tower
Hot fluid, which cannot be contaminated or lost, returns from the process and is introduced into the plate heat exchanger. In counter-current with the raw water from the cooling tower, it is cooled, returning to the process. The circuit water returns to the cooling tower. In this way, the operation of the system and its maintenance, together with the low acquisition cost, are decisive for your choice.
Application areas of the SF Cooling Tower
Commercial HVAC (Heating Ventilation and Air Conditioning)
Best equipment for your comfort air conditioning installation, with economical solutions and low maintenance cost.
Caravela-Thermotank's technical staff seeks to achieve excellence in the construction and performance of cooling towers. The result, for installations from 35 m3/h to 525 m3/h, is the SF series tower. The solution was to create a cooling tower that was fast to manufacture and of enviable quality. The SF cooling towers are built in juxtaposed panels, self-supporting extremely robust. The unique construction of SF cooling towers allows up to 60% shorter lead times due to prefabricated components and field installation up to 80% faster than similar equipment from other manufactures. The set, exchanger/pump tower, leaves the factory ready, avoiding assembly costs.
