ZEPHYR DX

The Zephyr DX air curtain was developed espencially for use in combination with an existing heatpump system. Established refrigeration technologies are applied here. The Zephry DX unit gives the option to blow warm air in winter and cold air in summer, in connection with an external heat pump. The Zephry DX is equipped with a refrigerant coil and a condensate tray (for up to 2 condensers) as standard. All electrical connections for controlling the unit by the customer are on the terminal block. The air curtain can also be provided with a second refrigerant coil, electric or warm water heat exchanger. This ensures that the Zephyr DX air curtain operates with sufficient heated air even in very cold environments to provide an effective air curtain.

In addition to the previously described function, the Zephry DX air curtain can also be used to optimise room tempertures. In winter the warm air produced by the air curtain prevents draughts in the entrance area of a building, because the air flow  works as a barrier and keeps the cold air outside. In summer the Zephyr DX air curtain will provide cooled air and keep the inside of the room comfortably cold. The warm air current in the winter and the cold air current in summer avoids air exchange and thereby results in considerable energy savings.

The Zephyr DX air curtain in combination with any heatpump system for all establishe cooling agents ( R410a, R407c ) is available in 5 versions:

• heating only- no condensate tray, no condensate pump.
• heating and cooling- with condensate tray (condensate pump optional)
• as per Zephyr DX, but with an additional DX condenser.
• as per Zephyr DX, but with an additional hot water LPHW heat exchanger for extra heating during low outdoor temperature.
• as per Zephyr DX-W, but with additional electrical heat exchanger.

On request Tekadoor air curtains can be supplied with energy saving EC motors. By using these EC motors. These EC motors running costs of air curtains can be reduced by 40 % compared with units using conventional motors.
