HEAT PUMP AIR CURTAINS
Panasonic Tekadoor air curtains come in two models and four sizes and can be used with both Panasonics PACi outdoor units and also their ECOi and ECOG VRF systems.
Standard Tekadoor models come in 1m and 2m door widths and are suitable for standard 3m height doors. This height should not be exceeded and is the units ideal operating height. Reduction of the height to 2.7m will give adequate performance but this deteriorates and at 2.4m the performance is significantly degraded. Do no use with a height lower than 2.4m.
Jet Flow Tekadoor models come in 1m, 1.5m and 2m door widths and there is also a VRF only 2.5m model. They are suitable for taller 3.5m high doors but this height should not be exceeded. Reduction of the height to 3.1m will give adequate performance but performance deteriorates below this and you should not install at a height lower than 2.7m under any circumstances.
The purpose of a door curtain is to retain heat inside a building that has either an open door policy or where the doors are frequently left open. A jet of warm air is created and forced down. mixing with fresh air and drawing this fresh air into the room. For correct operation the velocity is critical and this is why the restrictions on door height are important.
Air curtains are not new technology and have been in common use for many years. But traditional air curtains have used either hot water or electric heating. And lots of it! Using a heat pump means that you don't need a source of hot water and big pipes compared with hot water models or a huge electrical supply and high running costs associated with en electric model.
Further energy savings
In addition to being able to using energy saving heat pump technology the Tekadoor air curtain is designed to be controlled by a standard CZ-RTC2 controller with a 7 day time clock and can also be linked to a door switch. It is also possible to fit an additional control interface to connect with the buildings Wi-Fi network and subsequently control the curtain from a PC, smartphone or tablet.
Tekadoor air curtains are not only capable of heating but can also operate in cooling mode if required and include a drain lift pump.
The fan motors on these air curtains are the latest EC type energy efficient motors giving further energy savings.
You can maximise savings in areas with high heat gains by using a three pipe VRF system so heat taken out of areas requiring cooling is used to heat the air curtains.
PACi air curtains
The PACi version is very flexible and can be connected to a wide range of different PACi outdoor units depending upon the desired outlet temperature. We show a standard selection using Elite PACi outdoor units with the air curtain taking room air at 20C and heating it to 35C. For other selections please contact us.
