3 Unique Innovations

Electronic components protected by safebox

The electronic components are insulated from the outdoor environment, to protect them from adverse conditions such as corrosion, sand and humidity, in the special SafeBox that provides full IP55 protection.
Electronic boards are cooled down via a microchannel circuit to ensure the best operating temperature up to 55°C outside. Furthermore, the innovative heating system maintains correct
operation down to -30°C outside.

Multisensor control technology

Every component of the refrigerant system is constantly monitored, ensuring a high level of reliability and comfort, thanks to 19 sensors distributed throughout the refrigerant circuit.
At the same time, thanks to the digital twin technology, a virtual copy of a physical sensor can be created in the event of a failure, so that the system does not stop, thus ensuring comfort while waiting for maintenance to be carried out.
The function is only available with V8 indoor units and V8 platform controls

multisensor control technology

MR.Doctor 2.0

CVT8 units are equipped as standard with a special Bluetooth module to control all system parameters, which can be monitored and managed from the dedicated App, without needing to open panels, thereby simplifying start-up and maintenance operations.

High efficiency

EVI (ENHANCED VAPOR INJECTION) Compressor

Thanks to the vapor injection DC inverter compressor, the CVT8 series can run heating mode stably down to -30°C, furthermore strongly increasing the heating capacity especially at low ambient temperature. Compressor is designed to run at 7% modulation minimum, highly improving system efficiency at part load operation.

Enhanced heating capacity

Thanks to the vapour injection DC inverter compressor, the heating capacity is maintained at nominal when the room temperature drops to -5°C.

60 Steps capacity limitation

In projects with limited elecricity supply, capacity can be set to output from 40 to 100% with 1% discretization steps avoiding tripping and mantaining the system in operation.

Low standby power consuption

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

Wide application range

Wide capacity range

The whole lineup of VRF CVT8 is from 8HP to 96HP in 2HP increasement with the world’s largest single refrigerant system capacity up to 96HP.

Long refrigerant gas piping length

The length of the refrigeration lines can be extended up to 1100m, with a maximum height difference between indoor and outdoor units of 110m. The height difference between indoor units can be up to 40m. Thanks to these generous limits, the design of the air-conditioning system is greatly facilitated

Wide operating temperature range

VRF CVT8 can operate in a wide ambient temperature range.
It can operate stably from -15°C up to 55°C in cooling mode and from -30°C to 30°C
in heating mode.

High Reliability

Backup operation

In a multiple module system, if a single unit fails it is compensated by the operation of the other outdoor units, allowing the continuous operation.

In one unit with two compressors or fans, if one component is failed, the other one can act as a backup instead of the failed one to maintain up to 4 days interim capacity, allowing time for maintenance or repair while comfort remains guaranteed.

Duty cycling

Duty cycling equalizes the running time of the outdoor units in a multiple-unit system and of the compressors in each unit, significantly extending compressor lifespan.

In units with two compressors, they are switched on in sequence to balance their operating times.

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.

Please contact your local dealer for further information about customization price and availability.

Auto snow-blowing function

The innovatively designed auto snow-blowing function enables the outdoor unit to prevent the accumulation of snow by using air jet.

Dust-clean function

The innovatively designed dust-clean function enables the outdoor unit to prevent the dust by itself.

Enhanced comfort

Multiple priority modes

Operating mode priority can be set among 10 different modes to satisfy every specific user's need. Setting can be performed easily on field.

Silent modes

15 silent modes are available to fulfil any specific requirement.

Modalità silenziose VRF CVT8

Easy Installation and Service

Auto addressing

Outdoor unit can distribute addresses to indoor units and master/ slave outdoor units automatically. Remote and wired controllers can be used to query or modify each indoor unit’s address.

Automatic refrigerant charging function

Automatic refrigerant charging function makes the installation and service easier and more efficient, automatically collecting refrigerant from the tank and stopping the operation when exact refrigerant charge is done.

Automatic refrigerant recycling

Thanks to a specific setting, automatic refrigerant recycling allows to recover and store the refrigerant inside the outdoor unit or on indoor units side automatically when required before repairing, strongly simplifying the technical intervention.

Maintenance mode

If the power supply has to be cut off to some of the units during a technical intervention, maintenance mode can be activated and the rest of the system kept active.

Smart input / output contact

Convenient connectors are available as standard on unit PCB, to realize some convenient operations on field with other building appliances depending on users’ needs.

  • Input: Two contacts available including Cooling/Heating only mode and Force stop.
  • Outputs: One contact available including runnig status and alarm signal.

Fan esp up to 120 PA

The fan can be set to ensure up to 120 Pa of external static 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.
