Maxi MVD VR4+
Industrial range
Maxi MVD VR4+ (3 pipes)
The new system Maxi MVD VR4+ (3 pipes) allows heating and cooling different areas simultaneously with a single HVAC system. Which saves up to 50 % in energy costs compared to a conventional 2 pipe system.
The system consists of five basic modules that can be combined among them, allowing maximum power up to 180 kW and maximum pipe length up to 1000 m.

DC Inverter fan motor and compressor
All range units incorporate a DC Inverter fan motor and a compressor, in this way performance is improved in middle frequencies and ensure a more sensitive and effective control.
Wide range with multiple combinations
Five basic modules that can be combined as the customer wishes. System capacity can range from 8HP to 64HP in 2HP increments. In total you can connect up to 64 indoor units or a total capacity indoors that does not exceed 130 % of the capacity of the outdoor unit.
While heating defrosts
Thanks to the heat exchanger split into two stages, the equipment is able to defrost while sending high pressure gas to the indoor units. First performs a defrosting of the exchanger and then the other part.
Automatic capacity adjustment
The heat exchanger is split into two parts, thus it can use at the same time one part to evaporate and the other to condense, or it can use only one part if working with partial load.
Simplified communication connection
The installation of the communication wiring is simpler because in case you need to install a centralized control is not necessary to wire a second bus for communication between the indoor units and the central control. You can connect the central control (except CCM09) directly to the outdoor unit and perform manual routing for the control to detect all indoor units connected to that outdoor unit.
Low sound level
The optimal fan and the new design of the outlet air grill and the baffle allow a higher air flow and a minor sound level during operation.
Maximum length of pipe up to 1000 m
The Maxi MVD VR4+ system supports a maximum length of pipe up to 1000 m and a height difference of 70 m or even 110 m in case the outdoor unit is installed lower than indoor units.
Rotación & Backup
Thanks to the rotation function every unit can be started as master unit in a modular system, therefore, all compressors will work the same amount of hours.
Total compability
The Maxi MVD VR4+ system is compatible with all MVD indoor units.

Notes:
(1) Nominal cooling conditions: Indoor 27 °C DB, 19 °C WB and outdoor 35 °C DB, pipe length of 7.5 m and a height difference of 0 m.
(2) Nominal heating conditions: Indoor 20 °C DB, 15 °C WB and outdoor 7 °C DB, pipe length of 7.5 m and a height difference of 0 m.
(3) Noise level measured in semi-anechoic chamber at 1m distance front and 1.3m high.
(4) Refrigeration distances when outdoor unit is higher installed than the indoor units. Otherwise the maximum distance in vertical can reach 110m.
(5) Pipe diameter are of stop valves, this does not mean that the pipe should be this diameter. The oil balance pipe is only needed when two or more modules are connected.
(6) Power wiring recommended for L < 20 m, for longer distances will be calculated.
