I opt for lower operating costs. With a system for heating and cooling that consumes far less energy.

The new City Multi VRF outdoor units:

Future-proof VRF technology – freely scalable and cost-effective in every aspect. Lead. Extended.

Very high seasonal energy efficiency

Featuring an overhauled and even more efficient compressor, a reimagined refrigerant flow and a variety of additional design ideas, the new City Multi VRF outdoor units achieve up to 33% higher SEER and SCOP values – a considerable lead in terms of seasonal energy efficiency.

Up to 30% lower refrigerant fill quantity

The overhauled design of the City Multi VRF outdoor units has enabled us to reduce the refrigerant fill quantity by up to 30%, a major benefit in terms of building certification and ensuring compliance with EN378.

30% higher efficiency in heat transfer

the outstandingly efficient aluminium flat pipe heat exchangers from the City Multi EP series enable up to 30% more efficient heat transfer compared with round pipe heat exchangers. We have now positioned these on all four sides and in the upper section of the outdoor unit, ensuring far more efficient airflow and a lower refrigerant fill quantity. A clear lead in terms of cost-effective operation.

Faster route to efficient operation

The perfect blend of comfort and efficiency: in the winter months, the new smooth auto-shift start mode quickly ensures maximum heating output. After 30 minutes, the system automatically switches to energy-efficient operation. Another lead in terms of cost-effectiveness.

5 low-noise levels

The noise level can now be precisely configured in five levels rather than two and with a maximum reduction of 15 dBA to suit the requirements in different locations. These more exact gradations also enable reduced power loss.

Defrosting mode

The new City Multi VRF outdoor units perform defrosting without impacting user comfort. They achieve this by slightly increasing the air outlet temperature for three minutes prior to defrosting, then continue with constant heating at up to 50% of the heating output – even during the defrosting process. This delivers uninterrupted heating comfort at a consistent level.

Lead in investment

Very wide range of indoor units

The City Multi VRF systems can be connected to a wealth of different indoor units from a variety of series. All indoor units from the Mr. Slim and M series can be used alongside the City Multi indoor units, providing the ideal solution for every situation.

Continuous heating operation

The heat exchanger performs defrosting on alternate sides, delivering considerably greater comfort and a continuous heating output of up to 50% – even during the defrosting process.

Safe discharge function

The system is ready to be equipped with refrigerant detectors for the discharge function.

USB port

The USB port on the board makes it very easy to read out system operating data.

Eurovent certification

This certification ensures a range of benefits, such as guaranteeing that the stated efficiency data is binding.

All values and percentage-based improvements are stated in comparison with the previous series. The units contain the fluorinated greenhouse gas R410A.
