Conditioners industrial Toshiba Digital Inverter RAV-SM2804AT8-E

Each external block of the semi-industrial Toshiba conditioner 4 series allows connection of 2, 3 or 4 internal blocks. Thus, the Digital Inverter multisplit-system is capable to compete with VRF systems of small power. All external blocks are issued at the Japanese plant of Toshiba corporation in Fuji.

• Refrigerating capacity of 20 - 23 kW, it is possible to connect up to 4 internal blocks
• Cassette, compact cassette, channel, compact channel, subceiling, wall internal blocks
• Works for cooling to -15 °C, for heating to -20 °C
• Route length to 70 meters, difference of height to 30 m, does not demand refueling at the route to 30 m
• On our website - the instruction for installation and service of new external RAV-SM2244AT8-E and RAV-SM2804AT8-E blocks (access for the registered users)

Powerful two-rotor compressor

The compressor of industrial Toshiba conditioners differs in a povyshennoyeffektivnost and stability during the long work at a low frequency (partial loading) that considerably reduces electricity consumption.

• Efficiency of the engine due to advanced cooling is increased
• More effective compression of coolant due to application of details of precision accuracy
• Compression channels of a new design allowed to raise extent of compression of coolant.

Works to minus 20 degrees at the street

The built-in "winter set" allows semi-industrial Toshiba conditioners to work steadily 4 series for cooling at a street temperature to -15 °C. "The winter set" is built in already at plant, does not demand completions and the factory guarantee extends to it. These conditioners work for heating to -20 °C

The heat exchanger of the increased efficiency

Heat exchangers of external blocks in semi-industrial conditioners of Toshiba have the design promoting intensive heat exchange.

1. Tubes of the heat exchanger of two diameters.
Coolant in a liquid state flows on tubes of small diameter (8 mm). It leads to increase in speed of a stream and growth of heatexchange ability.

Gaseous coolant flows on tubes of big diameter (9,52 mm). It minimizes losses of pressure of coolant in the pipeline.

2. Two-row heat exchangers.
Two-row heat exchangers with the increased heatexchange ability are installed in Toshiba conditioners of the Digital Invertor series.

Length of the route is up to 70 meters

Big length of the route of semi-industrial Toshiba conditioners allows to solve the most complex problems of installation of external blocks. The maximum length of the Digital Inverter RAV-SM2244AT8-E and RAV-SM2804AT8-E pipelines makes 70 m.

The height difference between internal and the external block can reach 30 m. With a length of the route which is not exceeding 30 meters refueling by R410A coolant is not required.
