Large Splits
Axial Condensing fan
Benefits:
 Split system from 20 to 90 kW
 Ductable indoor unit
 Auxiliar heating (elect heater or hot water coil) available
 Allows ventilation, free cooling available
Where to apply / typical market:
 As an universal condensing unit to match with other systems (evaporator of a AHU)
 For offices where duct installation is the preferred solution against chiller+FCU or multiple minisplits
 Typical installations are anyplace where AHU is fitted, industry,
petrol stations

Large Splits
Centrifugal Condensing fan
Benefits:
 Split system from 20 to 90 kW
 Ductable indoor unit
 Auxiliar heating (elect heater or hot water coil) available
 Allows ventilation, free cooling available
 Indoor can be installed on top of the outdoor unit (compact solution)
Where to apply / typical market:
 As an universal condensing unit to match with other systems (evaporator of a AHU)
 Indoor Installations in technical room (to prevent from extreme outdoor temps or to install low noise
kits or no outdoor inst possible)
 For office buildings, supermarkets …

Axial Condensing fan
Compressor Soft Start: It is only needed to do the wiring connections. It
comes automatically adjusted from factory to the optimal point
Provides alarm signal in case of:
- Wrong phase sequence
- Low voltage
- Frequency out of range
- Locked rotor
- overheating

• Economizer & return fan
 Economizer can be assembled alone with
the unit
 Return fan needs to be ordered always with
return fan

Indoor unit VIR
• Hot water coil
• Modulating valve with 4 stages:
- Stage 1: Supply air 30°C
- Stage 2: Supply air 40°C
- Stage 3: Supply air 45°C
- Stage 4: Supply air 50°C
& Hot water coil minimum supply air temperature 15°C
• Anti freeze protection:
- If water temperature < 3°C, water pump and water valve are activated open
- Antifreeze protection stop when water > 6°C
• Jumper S2 give priority heat stages:
- jumper OFF: Heat pump compressors 1st and 2nd heat stage
- jumper ON: Hot water coil 1st heat stage

• Electrical heater
 Box tap with ventilating windows
 Contactor in 24V
 All heater inside the VIR, after evaporator coil (between fans phased out)
 The heater board to be installed on site in the outdoor unit
 2 x 0,75 mm2 cable to protect against EMC uncertainty
 All components at the opposite of refrigerating tubing for easy service
