Digital Scroll Compressor

The system is equipped with a DIGITAL SCROLL compressor that is set and controlled by a pulse width modulator (PWM). It incorporates the most advanced technology in the industry.

Wide range of power adjustment from 10 % to 100 %. Constant power adjustment. Long lasting: The solenoid valve PWM can be used 40 trillions times, that is equivalent to 30 years.

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.

Precise temperature control

Thanks to the advantages of digital scroll compressor, the system can quickly achieve maximum performance and shorten heating and cooling time.

It does not create electromagnetic interferences

The MVD system does not create electromagnetic disturbances, since coolant charging and discharging of the compressor are mechanical movements. These special features make it a system applicable to telecommunications companies, power plants and all kinds of precision measuring laboratories.

Auto addressing

The outdoor unit can assign address to the indoor units automatically.

Wireless and wired controls KJR-29B, can also configure, query and modify the addresses of the indoor units.

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 directly to the outdoor unit and perform automatic routing, so the control detects all indoor units connected to that outdoor unit, after you can modify the address manually with individual control of each indoor unit.

Maximum length of pipe up to 1000 m

The Maxi MVD D4+ system supports a maximum length of pipe up to 1000 m and a height difference of 70 m or even 110m 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.

Wide range of operation

The Maxi MVD D4+ system can operate in extreme temperatures in heating mode up to an outside temperature of -15 °C and in cooling mode up to 48 °C.

Total compability

The Maxi MVD D4+ system is compatible with all MVD indoor units.
