Free Cooling
Efficient concepts for your plants

Use air with outside temperature to cool your systems! With modern and individually manufactured solutions, you can reduce your air-conditioned electricity costs by up to 90% while protecting the environment. Power-intensive chillers are only used when the outdoor temperature exceeds a certain value. Particularly high energy efficiency and short payback periods make this technology attractive for your systems too! In combination with chillers, rack cooling or special installations, you can achieve high efficiency increases. Whether direct or indirect cooling, installation on the roof or in the wall: We will find a suitable solution for you!

CONCEPT

Direct free cooling

FIELD
  • Paper industry
  • Industrial solutions
  • EDP and IT infrastructure
ADVANTAGES
  • Energy-efficient open-air operation up to 95 % per year
  • Low payback period by reducing current energy costs by up to 90%
  • Individual commissioning as wall or roof installation
  • Minimized humidification effort at temperatures below 0°C due to high circulating air content
  • Resource-saving operation by using the waste heat for heating purposes.

BRIEF DESCRIPTION

With direct free cooling, you cool particularly energy-efficiently with air as the cooling medium. As a rule, the air circulating in the cooling system is cooled down with high current intensity and fed into the data centers or control rooms. With free direct cooling, the proportion of fresh air in the cooling air flow is increased by adding cold fresh air. The air exchange of the room takes place via a fan or through the floor. In the optimum case, the entire system can realize the required cooling capacity completely by direct free cooling. Power-intensive chillers are only switched on when the outside temperatures are too high.

CONCEPT

Indirect free cooling

FIELD
  • Paper industry
  • Industrial solutions
  • EDP and IT infrastructure
ADVANTAGES
  • Energy-efficient open-air operation up to 75 % per year
  • Low payback period by reducing current energy costs by up to 70 %
  • Individual commissioning as wall or roof installation
  • Resource-saving operation by using the waste heat for heating purposes.

BRIEF DESCRIPTION

In contrast to direct free cooling, in which the outside air is used directly for cooling, indirect free cooling transfers the cold via a pipe system to a water-glycol mixture. The mixture is cooled with fresh air using a recooler. Air-water heat exchangers are then integrated into the cooling water circuit of your cooling system. The heat load is dissipated to the outside air via the heat exchangers. In an optimal case, the entire system can realize the necessary cooling capacity of your plants completely by indirect free cooling. Power-intensive chillers are only switched on when the outside temperature is too high (over 18 degrees).
