Coiltech AB, a Swedish company associated with Luvata’s ECO specializing in the production of special heat exchangers and ventilated units for large industrial applications, now offers COOL, its well-known modular liquid cooler, integrated with an adiabatic filter for commercial and industrial applications in environments with medium to high external temperatures, which tend to come close to or even exceed the output temperature of the process liquid.  

 

Already recognized as the preferred solution over complex cooling towers, the adiabatic filter system has numerous advantages compared to other systems, such as the use of nebulized water.  In fact, the filters, by avoiding contact of the exchanger fins and tubes with the water, eliminate the risk of corrosion of the fins and tubes; moreover, preventing the formation of limescale and consequently saving on costly purification and demineralisation systems.   An item to be highlighted, especially for air conditioning systems, is the lack of water stagnation, a primary cause of the formation of Legionella. The filter system, in fact, allows the recirculation of the water through special ducting along with its complete re-use and substitution.  Even in windy environments, the cooling water, that is discharged and flowed down the filter, is not dispersed, contrary to how spray systems function, guaranteeing the maximum endurance of the system. 

 

The operation of the machine is managed by an electronic control unit with frequency converter that regulates the speed of the fan motor, the pump and the water valve. When the external temperature decreases, a sensor automatically blocks the adiabatic system, optimizing energy consumption.  ECO has already applied this same technology in its VCE-W, achieving excellent results.  In conclusion, the application of adiabatic filters, thanks to the water cooling of the air upon entry, allows for a significant reduction in the surface of the heat exchanger, consequently saving on raw materials and energy consumption, also enabling the reduction of the number of fan motors, reveals the company’s press release.
