RWEYQ-T9

VRV IV water cooled+ series

Ideal for high rise buildings, using water as heat source

› Environmental conscious solution: reduced CO emmisions thanks › Variable Water Flow control option increases flexibility and control
2
to the use of geothermal energy as a renewable energy source › 2 analogue input signals allowing external control of ON-OFF,
and typical lower refrigerant levels making it ideal to comply with operation mode, error signal, …
EN378 › Contains all standard VRV features
› Covers all thermal needs of a building via a single point of contact:
accurate temperature control, ventilation, air handling units,
Biddle air curtains and hot water
› Unique zero heat dissipation principle obviates the need
for ventilation or cooling in the technical room, maximising VRV-W
installation flexiblity Level difference between the VRV-W and indoor units:
› Wide range of indoor units: possibility to combine VRV with stylish 50m if the VRV-W is above
indoor units (Daikin Emura, Nexura, ...) 40m if the VRV-W is below
VRV-W
› Incorporates VRV IV standards & technologies: Variable Refrigerant Level difference between indoor units: 30m
Temperature, VRV configurator, 7-segment display and full inverter
compressors
› Developed for easy installation and servicing: choice between top Indoor installation Water piping
Unlimited water piping length
Refrigerant piping
or front connection for refrigerant piping and rotating switch box
for easy access to serviceable parts
› Compact & lightweight design can be stacked for maximum space
saving: 42HP can be installed in less than 0,5m2 floorspace
› 2-stage heat recovery: first stage between indoor units, second ErP 2021
COMPLIANT
stage between outdoor units thanks to the storage of energy in
the water circuit
› Unified model for heat pump and heat recovery version and Already fully compliant
