OPTIONS
Fresh air
- Free cooling for energy saving and fresh air management
- Exhaust fan module: this ensures overpressure extraction in case of high level of fresh air inlet.
- Return module: the return fan enables to overcome the return duct pressure drop, particularly during freecooling operation.
Indoor Air Quality
- EU4 / F7 panel filters
- Dirty filter sensor
- Indoor Air Quality sensor: To match minimum fresh air requirements with occupancy. It measures CO2 levels and adjusts fresh airflow rate accordingly.
Auxiliary heating
- Electrical heater: Standard, medium and high capacity heaters. Available with steps or modulating control.
- Hot water coil heater: includes the valves and has a proportional potential with CLIMATIC™ 50 advanced control
Refrigeration
- Winter cooling operation down to -15°C: Cooling operation are possible down to -15°C.
- Winter cooling operation down to 0°C: Cooling operation are possible down to 0°C.
- Long refrigerant piping: allows up to 65m piping between the internal and external units.
- Shut off service valve: easier installation & service operations. Includes a valve on the gas loop side and a valve on the liquid loop side of split units.
- Refrigerant pre-charged: split condenser supplied with factory filled refrigerant pre-charge. Includes shut off service valves, on liquid & gas loop sides.
Electrical and safety
- Main switch: situated on the Electrical panel of the condensing unit. The unit is shut off when the board panel is opened.
- Phase sequencer: this prevents the compressor from starting if the phases are reversed.
- Air sock control: Soft start control of supply fan allows the air socks to be progressively filled with air on start up.
- Smoke detector: (optical head)
Other options
- Low Noise & Winter Operation with Inverter control: Reduce radiated noise level. Cooling operations are also possible down -15°C.
- Precoated coil: outdoor or indoor coils anticorrosion treatment. Particularly recommended in salin or polluted environment.
- Coil protection grill: It prevents condenser coil against accidental impacts.
- High pressure 250 Pa FP1:Available static pressure for outdoor unit up to 250 Pa.
- Rubber anti-vibration mounts: To avoid transmission of vibrations for the floor where the unit is installed while unit is operating.
