The ECM range makes use of the excellent experience gained with the Cassette fan coils with inverter board, first in the world in production since 2009, and which have had great success on all markets.
The innovative brushless and sensorless type synchronous electronic motor with permanent magnets, is controlled by an inverter board designed and developed in Italy. The board is mounted on the unit, closed to the motor, without the need to be cooled down by the air flow.
The air flow rate can be varied in continuous by means of a 1-10 V signal generated by Sabiana controls or by independent control systems. The continuous air flow control improves the acoustic comfort and allows a more punctual reply to the variation of the thermal loads and a greater stability of the requested ambient temperature.
The extreme efficiency, also at low speed, makes possible a great reduction in electric consumption (less than 50% in comparison to CRT range motor) with absorption values under normal operating conditions that do not exceed 8 Watt
The excellent values of the CRT range in terms of sound levels have been maintained in all working conditions, without any resonance phenomenon at any frequency.
The full compliance with the Electromagnetic Compatibility Directive and with the other severe Standards in force is certified by an independent institute.
The CRT-ECM series with tangential fans comes in 5 versions, 6 sizes, 6 models with single coil and 6 models with double coil, with air flow-rates ranging from 95 to 900 m3/h, heat outputs from 1 to 10 kW and cooling capacities from 1 to 5 kW.
