  • PT - heating capacity
  • Tp1 - air temperature at the unit inlet
  • Tp2 - air temperature at the unit outlet
  • Tw1 - heating medium temperature at the heat exchanger inlet
  • Tw2 - heating medium temperature at the heat exchanger outlet
  • Qw - heating medium flow rate in heat exchanger
  • Δpw - heating medium pressure drop in heat exchanger

If you want to calculate heating capacity at different parameters you can do this at manufacturer website.

High productivity and successful integration of new materials allowed the company FLOWAIR to reduce the price, but not the quality of its air curtain ELiS T. The casing from EPP (expanded polypropylene), which was a matter of great interest at the beginning, has become an integral part of the air curtains ELiS T. Thanks to the material, the casing has become lighter, however, remains strong and elastic at the same time. The grey-coloured air curtain ELiS T in the modern design is a multi-purpose unit – it can be mounted both horizontally over doorways and vertically along the side of a doorway. The stronger air blow, which can be adjusted with a three-speed controller makes it possible to mount the air curtain at the height of as many as 4 meters (see Fig. 1). The air from the intake of the unit is preheated by a hot water heat exchanger; meanwhile, the flow fans blow the preheated air out (see Fig. 2). The air curtain ELiS T has water connections on the top and on the left; the heat exchanger has an air relief valve on the right. This allows vertical installation of the air curtain both on the left and right side of a doorway.

ELiS T air curtains principle of operation
Fig. 2: Principle of operation of an air curtain ELiS T: (1) the air from the intake is preheated by a hot water heat exchanger inside, and (2) the air is blown downwards with a flow fan.

Air curtains ELiS T are available in three sizes: 1 m, 1.5 m and 2 m long. Furthermore, the curtains can be mounted in a row to create a screen of required width (2.5 m, 3 m, 3.5 m, etc.). In order the air curtain turned on automatically each time the door is opened, and turned off automatically upon the door closed, a mechanical door contact can be involved. If you want the unit to respond to the signal from a magnetic door contact, the DRV control system module is needed (see Fig. 3). The module can be ordered as an option. DRV is an advanced control system which can be connected to BMS (building management system). To disconnect the heating for the air curtain, a servo valve is needed which stops the supply of hot water to the heat exchanger. The valve is controlled with a thermostat or magnetic door sensor.

Enhanced air flow, decreased weight, attractive design and an even better price make the air curtain an excellent choice for commercial enterprises, public institutions and other places, where an effective air screen is needed to protect heated or cooled premises against cold or hot air forcing from the outside to the inside through a door, which is opened on a constant basis.

The advantages of a universal water air curtain ELiS T with EPP casing:

  • Stronger air flow at a better price!
  • Universal air curtain – for installation both horizontally and vertically.
  • EPP and steel casing. The framework is from galvanized steel.
  • An air screen protects against: winter cold, summer heat, smoke, bad smells, insects, dust.
  • A wide selection of models: the air curtains are available in three sizes; they can be mounted in a row to obtain the required length.
  • Only premium quality components: cross flow fans, high quality copper heat exchangers with aluminum plate-fins, a casing from steel and expanded polypropylene.
  • A wide scope of application.
  • Quality guarantee – European product with technical properties meeting the declared values, CE certified.
  • Extensive application: shops, banks, bookstores, pharmacies, hotels, restaurants, cafes, pubs, administrative offices, vestibules and other objects.
  • DRV control system module as an option. The DRV control system can be connected to BMS. The DRV control system provides the possibility to operate up to 5 air curtains with a single control panel, also engage a magnetic door sensor.
