Compact heat pump outdoor units Mini VRF MSAN8-X

High Efficiency

  • FULL DC INVERTER TECHNOLOGY

The DC inverter technology adopted for both the compressors and fans means that they precisely fulfil the load required by the system while ensuring efficiency, continuity of operation and a greater silence level.

  • ADDITIONAL EXCHANGER FOR SUBCOOLING CONTROL

Using a plate heat exchanger as a secondary intercooler can increase refrigerant subcooling by up to 15°C, thereby improving heat exchange and energy efficiency.

  • MINIMAL CONSUMPTION IN STANDBY MODE

The optimised control system reduces power consumption during standby mode by up to 3.5 W.

  • 60 STEPS OF CAPACITY LIMITATION

If the power supply is limited, the units can be controlled to provide between 40% and 100% of the capacity with a 1% discretisation step.

Large field of application

WIDE OPERATING RANGE
The guaranteed operating range is very extensive. The units can operate stably at outdoor temperatures between -15°C and 52°C in cooling mode and between -20°C and 30°C in heating mode.

EXTRA LONG REFRIGERANT PIPING
The length of the refrigerant piping can be extended by up to 300 m, with a maximum height difference between indoor and outdoor units of 50 m. The level difference between indoor units can be up to 15 m. Thanks to these extensive limits, the design of the air conditioning system is extremely easy.

REFRIGERANT COOLING PCB

High Reliability

ANTI-CORROSION PROTECTION
Outdoor units are given anti-corrosion treatment for non-extreme conditions as standard and can also be customized with heavy anticorrosion treatment on main components for surface protection against corrosive air, acid rain and saline air (for installations in coastal regions) to extend overall useful life. The integrity of the anti-corrosion treatment is ensured by subjecting major components and parts to salt mist testing, moisture and heating testing and light aging testing.

REFRIGERANT COOLING PCB
The MSAN8-X series uses refrigerant cooling technology to cool the electric control box. It decreases the average temperature of electrical control components by about 8 degrees, guaranteeing the stable and safe running of the control system.

Easy installation and maintenance

STATIC FAN PRESSURE UP TO 35 PA
The fan can be set to ensure up to 35 Pa of available pressure. In this way, the outdoor unit can be installed in technical rooms or in areas where the correct natural air flow cannot be ensured, ducting the air exhaust from the unit to the outside. 
AUTOMATIC REFRIGERANT RECOVERY
Thanks to a specific setting, the recovery and storage of refrigerant can be set in the outdoor unit or in the indoor units, thereby facilitating technical intervention and maintenance times.
COMPACT DESIGN AND EASY TRANSPORT AND INSTALLATION
The compact design and light weight of the units minimise the footprint, reducing the weight loaded
on the surfaces and making transport easier. The units can also be transported by lifts or forklift trucks, hence reducing installation time.
This makes the system particularly suitable for applications where the visual impact on architecture needs to be limited, such as on historic or prestigious buildings.

AUTO ADDRESSING

AUTO ADDRESSING

Outdoor unit can distribute addresses to indoor units automatically. 
Remote and wired controllers can be used to query or modify each indoor unit’s address.
SMART INPUT / OUTPUT CONTACTS
Standard supplied, practical connectors are available on the unit's electrical board to allow operations on site with other equipment as required by the user.

  • Input: Two contacts available to choose between cooling/heating mode only and forced shutdown.
  • Output: One contact available to choose between operation status and alarm signal.
