Cassette air conditioners FORT II Inverter series

FORT II Inverter is the latest generation cassette air conditioners with a DC–inverter compressor. They are installed behind the suspended ceiling of offices, restaurants, shopping malls, hotels.

A neat white decorative panel with a circular flow of a cassette air conditioner goes well with any stylistic design and provides a reliable air supply to all corners of the room, and a built-in drain pump allows you to install the unit even in places where it is impossible to ensure a downward slope of the drainage pipeline.

Inverter systems of the FORT II Inverter series are represented by models: 18,000 BTU/h (RU2DC18BE), 24,000 BTU/h (RU2DC24BE), 36,000 BTU/h (RU2DC36BE), 48,000 BTU/h (RU2DC48BE), 60,000 BTU/h (RU2DC60BE).

* The amount of freon is indicated for the pipe length of no more than 5 m. With an increase of the pipe length, it is necessary to charge the additional refrigerant at the rate of 12 g per 1 m for the 1/4″liquid pipe and 20 g per 1 m for the 3/8″liquid pipe.

** Cut-off current is not less than 7 In (In - rated current), leakage current is not more than 30mA, shutdown characteristic is «C». It is allowed to install the circuit breaker and RCD with the same capacity in series.

The table shows data for temperature conditions in accordance with ISO 5151-94:
- cooling mode inside 27 °C (DB)/19 °C (WB), outside 35 °C (DB)/24 °C (WB)
- heating mode inside 20 °C (DB)/15 °C (WB), outside 7 °C (DB)/6°C (WB)
