INTRODUCTION

SB.RKXYQ-T(8)

VRV IV heat pump for

indoor installation
AIR PURIFIER

The invisible VRV

› Unique VRV heat pump for indoor installation
HEATING

SPLIT
› Unrivalled flexibility because the unit is split up into two elements:
the heat exchanger and the compressor SB.RKXYQ5T8
Heat exchanger
unit
SKY AIR
› Covers all thermal needs of a building via a single point of contact:
Max. 70 m accurate temperature control, ventilation, air handling units and
Biddle air cutains
Max. 30 m Compressor unit can be above heat
VRV Indoor exchanger unit as well › Lightweight units (max. 105kg) can be installed by two people
units
› Unique V-shape heat exchanger results in compact dimensions
(h/e unit only 400mm high) allowing false ceiling installation, VRV
while ensuring top efficiency
Compressor unit › Super efficient centrifugal fans (over 50%
› Highly suited to densely populated areas thanks to the low efficiency increase compared to sirocco fan) ErP 2021
COMPLIANT
operation sound and seamless integration into surrounding › Small footprint compressor unit (760 x 554 mm)
architecture as only the grille is visible maximizing useable floor space Already fully compliant
› Incorporates VRV IV standards & technologies: Variable Refrigerant › Contains all standard VRV features to LOT 21 - Tier 2 VENTILATION & BID- DLE AIR CURTAINS
Temperature, VRV configurator and full inverter compressors Published data with
real-life indoor units
