Outdoor

Y Series (4-6hp)

The latest in Mitsubishi Electric R410A Y Series technology. The new City Multi models allow up to 12 indoor units to be connected to a single outdoor unit, using the standard branch/header pipework system proven in the larger models. Utilising the latest Mitsubishi Electric inverter technology, the system is fully controllable with all City Multi controllers or linked to third party BEMS.

A two core non-polar transmission line allows for simple installation of up to twelve indoor units now
Latest in inverter technology including a highly efficient DC Scroll Compressor, DC fan motor and Demand Control
The condensing unit is extremely slimline which allows easy location and application of the system
Single or three phase power supply
Anti-Corrosion blue and flat fin technology

Y Series Standard (8hp-50hp)

Improved for even higher efficiency

The City Multi Y Series makes use of a two pipe refrigerant circuit throughout, with the choice of either Branch Pipe or Header Pipe feeds to indoor units, with manual changeover from cooling to heating to ensure that a constant indoor climate is maintained.

Wrap around coil for improved energy efficiency
Choice of Branch Pipe or Header Pipe feeds to indoor units
Energy-saving inverter driven outdoor compressor units with very low start currents
No requirement for plant rooms or bulky service shafts
Weight and size reduction compared to YGM-A models
Improved pipe run of 165m, with a total system pipe length of 1000m
100% inverter control
High Sensible Cooling Function - By raising the off coil temperature, a 10% increase in sensible cooling capacity over standard operation is achievable, the result being greater comfort for occupants
High Performance Heating Mode for low ambient conditions

Y Series High COP (8-36hp)

Highest ever COP’s / EER’s due to new higher efficiency inverter technology and wrap around coil
Choice of Branch Pipe or Header Pipe feeds to indoor units
Energy-saving inverter driven outdoor compressor units with very low start currents
No requirement for plant rooms or bulky service shafts
Weight and size reduction compared to YGM-A models
Improved pipe run of 165m, with a total system pipe length of 1000m
100% inverter control
High Sensible Cooling Function - By raising the off coil temperature, a 10% increase in sensible cooling capacity over standard operation is achievable, the result being greater comfort for occupants
High Performance Heating Mode for low ambient conditions

Y Series Zubadan (8-20hp)

Zubadan sets a new standard in performance

The new City Multi Zubadan heat pumps achieve an excellent heating performance even when the outdoor air temperature is as low as -25ºC.

Stable Heating Performance - Full heating capacity at -15°C - a 40% capacity improvement over the standard YJM-A model
Expanded Heating Operation - Will work effectively even when the outdoor ambient air temperature is -25°C
Stable Operation - Utilising the new Flash Injection Circuit the Zubadan models have reduced defrost times and can provide continuous heating for up to 250 mins
Quick Start-Up - Full heating capacity is achieved in about 20 mins, improving comfort levels
Energy-saving inverter driven outdoor compressor units with very low start currents
100% inverter control
High Sensible Cooling Function - By raising the off coil temperature, a 10% increase in sensible cooling capacity over standard operation is achievable, the result being greater comfort for occupants

Y Series Replace Multi (8-36hp)

Enables the replacement of VRF systems, whilst utilising existing R22 / R407c pipework.

The latest VRF Replace Multi from Mitsubishi Electric is specifically designed for the maturing refurbishment sector, enabling the reuse of existing R22 / R407c pipework, whilst also allowing the upgrade to some of the most efficient systems available in the market.

Replace Multi will clean the existing pipework during commissioning, removing any deposits and R22 mineral oil that would have ordinarily meant that new pipework would have been called for. The implications of this are significant savings on cost and time, whilst also minimising any potential disruption.

Efficient use of existing resources - refrigerant piping, control and power wiring and less waste materials
Increased energy efficiency - up to 105% more efficient than an old Mitsubishi Electric R22 system (size 200)
Reduced installation costs of up to 55%
Reduced CO2 emissions and running cost savings of up to 45%
Reduced installation time with minimised disruption
Ability to replace many non Mitsubishi Electric systems
High Performance Heating Mode for low ambient conditions

WY Series (8-36hp)

Heat Pump, Water Cooled Condensing Unit

The WY Series has all the benefits of the Y Series using water cooled condensing units. It is also able to produce heat recovery via the water circuit between heat source units, making for a very economical system. Like the YJM-A air source versions, the water cooled units now benefit from a modular design approach. A twinning kit is required for double combinations.

High COPs possible thanks to increased efficiency and careful control of the system, allowing the largest operational water circuit temperature band ever
40% height reduction compared to previous YGM-A models
Combining WY with waste heat energy provides unique application solutions
Up to 50 indoor units can now be connected to each condensing unit
Single inverter compressor
Improved pipe run of 165m with a total system pipe length of up to 500m
High Sensible Cooling Function - By raising the off coil temperature, a 10% increase in sensible cooling capacity over standard operation is achievable, the result being greater comfort for occupants
Able to operate with closed loop ground source water temperatures, bore hole and slinky applications are now possible
Easy maintenance - front panel access to all PCB’s
Condensing units must be situated indoors
