Centrifugal roof mounted fan in vertical discharge format fitted with:
- EC external rotor motor.
- Centrifugal backward curved impeller.
- Steel finger guard.
- Base manufactured from galvanized sheet steel.
- ON-OFF electrical isolated switched.
Motors
High-performance and low-energy-consumption EC brushless motor with external rotor, ball bearings and thermal protector.
Single phase models 230V±10% 50/60Hz, IP44.
Three phase models 400V±10% 50/60Hz, IP54.
MODELS 250 TO 355
With built-in plug and play control, pre-configured to work at a constant pressure (COP) and a set point of 100 Pa. The PROSYS ECOWATT programming console will allow you to adjust the settings of the constant pressure (COP) mode and three additional modes:
- Constant air volume (CAV).
- Proportional (VAV).
- Mínimum-Maximum.
- Time programmer (TIMER RTC accessory needed).
Constant Pressure operation mode (COP)
- Minimum fan speed between 0-50%.
- Maximum fan speed between 50-100%.
- Night position adjustable between 25-100% of the pressure in high speed.
Constant Volume operation mode (CAV)
- Minimum fan speed between 0-50%.
- Maximum fan speed between 50-100%.
- Night position adjustable between 50-100% of the volume in high speed.
Proportional operation mode (VAV)
- 2 analogical inputs 0-10V or 4-20mA.
- The control operates in function of the maximum demand parameter.
- Minimum fan speed between 0-50%.
- Maximum fan speed between 50-100%.
- Alarm relay output.
Min-Max operation mode
-Function of the contact position connected to digital input, the fan runs at high speed or at low speed.
- Minimum fan speed between 0-50%.
- Maximum fan speed between 50-100%.
Timer (RTC)
By purchasing the Timer (RTC) accessory alongside the PROSYS ECOWATT programming console you will be able to programme a time period for it to operate.
- Up to three time periods with the chosen set point.
- Holiday periods.
MODELS 400 TO 630
With built-in plug and play control, pre-configured to work at a constant pressure (COP).
These models feature:
- Remote on/off relay.
- Boost relay.
- Night mode relay.
- Two-way alarm relay.
In addition, its built-in electronic system allows you to manually configure the following operating modes:
- Constant airflow volume (CAV).
- Variable air value (VAV).
-Minimum-maximum.
- Modbus RTU communications.
N.B.: The PROSYS ECOWATT programming console and the TIMER RTC ECOWATT timer module are not compatible with these models.
- EC external rotor motor.
- Centrifugal backward curved impeller.
- Steel finger guard.
- Base manufactured from galvanized sheet steel.
- ON-OFF electrical isolated switched.
