- Electronic variable speed control with very low consumption compared to a conventional frequency inverter. The efficiency of the motor remains high at both high and low air flows - Measuring the flow rate through a calibrated section at the fan intake and a differential pressure sensor allows the control to handle the flow rate reliably and precisely in both CAV and VAV systems. - The soft start of the fan is adapted for textile ducts and limits the starting current. - With constant air volume, management of 3 different setpoints for flow rate (hot, cold, neutral). - With variable air volume and with the tandem option, there is a reduction in air flow at partial load. Reusable air filters, mounted in a frame. Copper tube coil and aluminium fins. Condensate drain pan. Thermostatic expansion valve with external equaliser.
Casing made of galvanised sheet steel panels with polyester paint in RAL 7035 white. Thermal insulation (9 mm thick), with B-s3,d0 (M1) fire classification as standard. Free-standing frame and access panels for the electrical cabinet, compressors, fans, and filters, fitted with quarterturn locks. Panels are mounted on hinges from size 200.
EC electronic propeller fan(s) which adapt their rotation speed to the installation's requirements, thereby reducing consumption of electricity and the sound level at partial load, and improving the unit's average seasonal efficiency. Copper tube coil and aluminium fins.
EC supply air plug fans with variable speed control and flow rate controller. In tertiary sector installations, a high percentage of the annual air conditioning energy consumption comes from the use of fans for transporting air. Using fans which are more efficient has a direct impact on reducing consumption. EC plug fans with direct drive and variable speed offer the following advantages: - Elimination of friction losses during transmission thanks to the direct drive, with no belts requiring maintenance. - Greater aeraulic efficiency of the fans (reactive blades with an optimised profile), running at very high operating pressures. - Greatly increased motor efficiency. Permanent magnet EC motors activated using electronic switching integrated into the motor itself (improvement on the IE3 motor). - Variable speed to ensure a constant supply air flow rate, independent of the filter fouling level and which is able to adapt to pressure drops in the network.
Tandem hermetic scroll compressors which improve the management of stages and comfort and the unit's energy efficiency under partial loads. Reduction in defrost cycles. Fitted on anti-vibration mounts. Direction of rotation and phase balance control. Crankcase heaters. Four-way reversal valve (heat pump units). Acid-resistant filter dryer(s).
- Architecture of refrigerating section: • 1 air volume: models 90 to 180 • 2 air volumes: models 200 to 360 (alternating defrost).
