Mini VRF outdoor units

The heart of a modern air-conditioning system

Kaisai Mini VRF outdoor units have been designed for projects requiring high efficiency, design flexibility and reliable operation all year round. The compact design of the units allows for installation even in confined technical spaces — on roofs, balconies or building facades — without compromising on performance.

The system allows for the connection of up to 9 indoor units, enabling the creation of extensive air-conditioning systems for offices, apartments, commercial premises or small hotel facilities. With installation lengths of up to 100 metres and the ability to oversize indoor units by up to 130%, the solution offers great design flexibility and optimal adaptation to the project’s requirements.

Energy efficiency and stable operation all year round

The use of DC Inverter technology ensures smooth regulation of the compressor’s operation, reduced energy consumption and stable maintenance of set parameters. The system quickly reaches the required temperature, whilst minimising fluctuations and improving user comfort.

The units operate efficiently even in harsh weather conditions — in a temperature range from -20°C to +49°C — making them a suitable solution for both cooling and heating buildings all year round.

Advanced technologies enhancing reliability

The PCB electronics cooling system using a refrigerant increases component lifespan and improves the stability of the unit’s operation. Intelligent defrosting reduces downtime during heating, whilst the integrated PCB design simplifies servicing and enhances the reliability of the entire system.

An additional advantage is the ability to integrate with BMS systems and air handling units, enabling the creation of comprehensive and modern HVAC installations for commercial premises.
