W-TECH SRL

Evaporative towers are used in industrial process cooling. Wherever there is a need to cool a large flow of water, evaporative towers W-tech are your best solution for: - Energy production plants and cogeneration - Metallurgical plants - Chemical-pharmaceutical plants - Food plants and concentration - Industrial plants in general/air conditioning and refrigeration - Plants for moulding, plastic blowing, paper mills From a structural point of view, the range is divided into towers with centrifugal or axial fans (suction or pressure), special towers for particular uses, towers for use with high-temperature thermal water, towers for aggressive water, towers suitable for transport in containers.

The Dry cooler, also called liquid coolers, are used in applications where you choose not to use water. The advantages are many, from the elimination of possible lime residues on the coils, to the zero water consumption, to lower noise emission. The advantages are balanced by a higher power consumption compared to evaporative towers, a larger installation surface necessary and higher fluid outlet temperatures. W-tech also produces Dry cooler "WET", equipped with a water misting system that allows you to lower the outlet temperature of the fluid to be cooled, such as during the hottest hours of the day and during seasonal peaks. W-tech produces from the best known table versions to "V" versions with single and multi-fan, as well as copper coils with pre-painted fins or multi-circuit versions.

WHAT IS AN EVAPORATIVE CONDENSER? An evaporative condenser transforms a refrigerant gas, from a gaseous to a liquid state. The refrigerant gas condenses and changes phase as it travels from top to bottom in a coil sprayed with water and counter-current air. Medium to large capacity refrigeration systems are usually water-cooled, especially if they use ammonia as a refrigerant. The choice of a water condensing unit such as evaporative W-tech condensers over air condensers is simple: - Consistent performance throughout the year due to lower condensing temperatures - Higher thermal efficiency during winter/summer months - Optimum efficiency thanks to the use of recirculating water in fall with countercurrent air - Lower power consumption compared to an air unit

Our industrial process cooling machines are the perfect solution for the countless requirements of production processes. The choice of a process cooling system is linked to two main aspects, the first is its TCO (Total Cost of Ownership) i.e. efficiency, i.e. electricity consumption, and environmental impact, with both present and future regulatory restrictions. Our chillers are distinguished not only by their high performance, but also by their low environmental impact due to the use of natural gases such as R290, ammonia and to CO2 (they comply with ERP TIER2 regulations).

Evaporative coolers differ from evaporative towers in theu se of a heat exchange coil for the primary process fluid. WHAT DOES THAT 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 inside a heat exchange coil: the fluid is not contaminated by particles present in the water and from atmospheric agents. Glycolated fluids can be used safely thanks to the use of the heat exchange coil. The units can operate "dry" (dry mode) in sub-zero winter conditions, without recirculating water only with the fans running.
