Get the highest efficiency and lowest energy-consumption with this air curtain for freezer doors

This unique high-pressure air curtain system was specially developed for use for doors between large freezers in combi with big conditioned front rooms. Here, the function of temperature and humidity separation is split into two individual functions. The temperature separation is ensured with a predefined outblow angle of the separation air jet against the natural flow direction. Another, patented conditioned air jet is applied to the separation air jet and protects the deep-freeze area from penetrating humidity. Since this is done with a high degree of efficiency, we refer to it as an insulation air layer.

Product information

Key features

  • Maximum efficiency and low energy consumption are the keywords describing the system the best.
  • Specially designed for logistic freezer environments with changeable components to keep costs to the  absolute minimum.
  • Also available in hygenic stainless steel
  • Specially designed for different type of situations and areas with different levels of humidity load.

Powerstream®

The Powerstream® system consists of an external fan and two vertical discharge modules. As standard, this basic system is installed on the freezer side. In opposite to the typical Masterveil approach, the tailormade length is reached by combining standard modules. The blow-out modules are positioned to the left and right of the door.

More features

  • Depending on requirements, the insulation air layer is conditioned with an electric heating coil, a glycol coil or an active dehumidifier.
  • Due to the patented separation of functions into separation and insulating air jet, the energy requirement is reduced to a minimum.
  • The entire system is controlled via a control cabinet and can be connected directly to the building management system.
  • The fans are based on EC technology in accordance with the latest ErP regulations.
  • They have an adjustable operating point, so that a zero point is demonstrated in each case as proof of correct function and screening.
  • The specially developed nozzles have a very smooth surface to avoid the smallest turbulence in the air jet.

Basic system extended with:

Airlock system on the warm side for large humidity loads, large temperature differences or to 15 % increase system efficiency. This extension system has the same design, but only one additional separating air jet.
