The ASR2 ECOWATT system from VIM allows the following to be achieved in the air treatment installations of professional kitchens:

Control of one or more extraction fans with a single compensation unit.
The distribution of fresh air in the different zones.
Fire safety management.
Comfort operation in manual, automatic or time-programmed mode.
Control and monitoring of the operation of UVC treatment cabinets.
Display and regulation of the different extraction and compensation flow rates.
Centralization of operating and fault information from the air handling unit.

Comfort mode operation

The two main extraction zones are equipped with a local CVF control which allows the simultaneous start-up of the associated extraction fan and the CTA and the opening of the corresponding VAV box. It also allows the extraction and compensation flow rates to be varied manually.
For each zone, depending on the CVF setpoint, the CASR box will control the speed variation of the ECM motor of the corresponding ASR extraction fan and will transmit a flow setpoint to the VAV box.
Flow control of the main extraction zones can be ensured by implementing a VORAX® ECO automatic management system.
The BCCA 1V control of the fixed zone allows the simultaneous start-up of a standard extraction fan, the CTA and the opening of the VAV box.
The three zones can be operated independently.
The system synthesizes the requested insufflation flow rates of the three zones and transmits a 0-10 volt signal to the CTA equipped with a CORRIGO VIM for flow control.
The fresh air compensation flow rates can be supplied by hoods (VORAX® or NOVAX Confort 90/10 type compensation hoods) or by diffuser networks placed in the respective zones.
As soon as the extraction fan in a zone is started, the CASR box will authorize the opening of the associated gas solenoid valve if it is present.
In the case of an extraction zone containing a hood equipped with a grease and odor treatment system (NOVAX UV range), the CASR box will manage the start-up of the associated ARUV cabinet. By feedback of the operation of the UVC lamps, an operating hours counter will be incremented. A post-ventilation will make it possible to stop the UV lamps before the extraction fan in order to evacuate any ozone residues in the duct.
The ETD2 RASR remote control allows the display of the operating mode, real-time flow rates and the various alarms of the system, including that of the CTA. It also allows the CTA blowing temperature setpoint to be modified within the limit of a deviation of + or – 3 degrees.

Smoke evacuation mode

Triggering a BDRA punch, regardless of the zone, allows the smoke evacuation mode to be started and the "fire" inputs of the CASR box, the CTA and the two fans of the variable zones to be activated. The "fire" inputs have priority over all other inputs regardless of the operating mode of the system.
In smoke evacuation mode, the extraction fans operate at their maximum speed, the gas solenoid valves are closed and the ARUV cabinets are stopped.
Depending on the requirements of the safety commission, the CTA operates at its maximum flow rate or is stopped.
A self-hold function is implemented and an alarm is generated on the ETD2 RASR remote control.
