Applications and characteristics

  • Industrial applications in all common industries especially for cooling of industrial furnaces and emulsions of wire drawing machines
  • Series KT-A also particularly suitable in the field of building technology for cooling of small absorption / adsorption chillers
  • For outdoor installation
  • Water inlet temperature to 65°C
  • Cooling water temperatures depend on ambient air temperatures and -humidity; customizable by speed control of the fans
  • Operation with pure water (without glycol)
  • Energy-efficient fans acc. Ecodesign Directive 2009/125 / EC
  • Low weight
  • Easy maintenance due to simply dismantling of cover parts
  • Wear-resistant, robust and durable
  • Easy installation
  • Noise protection features (silencers, impact absorbers) available
  • Special designs and wide range of accessories available

Design

  • Housing made of GRP (glass reinforced plastic)
  • Axial fan arranged at the top; particularly quiet running and energy efficient by special bionic airfoil blade
  • Air is "sucked" through the cooling tower
  • Water distribution made of plastic
  • Pollution secured plastic spray nozzles
  • Wet deck as high-efficient foil fillers made of polypropylene

Mode of action

The (evaporative) cooling tower is a wet water / air heat exchanger. In the open cooling tower the water to be cooled is brought into direct contact with the air. In this, usually in countercurrent flow extending operation, the down-flowing water emits heat to the rising air by evaporation and convection. In the cooling tower the water is evenly distributed by nozzles over trickling material (fillers).

Due to the evaporation process water losses arise. These losses must be supplied to the circuit at a suitable point.
