ATT Technical Parameters

ATT is a frame with a covering comprising of the following main components:

• Turbo compressor — UPEC-engineered high speed and high efficiency turbo compressor with a unique design for ATT. Compressor and turbine stages of every turbo compressor type and size are in agreement within the whole range of ATT modes.

• Heat exchanger — UPEC-engineered highly-efficient super-compact air-to-air heat exchanger. Temperature efficiency in the design mode is up to 95%.

• Fans — energy-efficient centrifugal Green tech fans with an EC-motor manufactured by the world leader in this area – German company Ebmpapst, which save from 30 to 80% of consumed energy in comparison with conventional AC-fans.

• Air ducts, valves, flaps, silencers with minimum aerodynamic drags.

• Frequency inverter — highly efficient and reliable, manufactured by the world leading company Shneider.

• ATT is a monoblock unit introduced with a number of models distinguished by the performance.

Warranty period – up to 2 years
Life time – up to 10 years
No need in oil filling
No freons, no refrigerants
Working medium – air
No need in drainage in summer
No need in auxiliary system “winter package”
Additional options – water heating in summer

Onsite the unit needs to be connected to the air lines of premises and environment, as well as power supply.
No other connections are needed, except the cases when a system has a “water heating” option.
There are spaces for air duct and power supply connections on the outer surface of the frame.
