The KAPPA SKY products already meet the energy efficiency requirements of the EcoDesign Directive Tier 2, which does not come into force until 2021 – offering end users a future-proofed solution.
The new chillers operate with the low GWP refrigerant R513A as a default option, although they can also operate with R134a. The former has a GWP of 573 and the range also offers an ultra-low GWP option, which uses 1234ze.
The 32mm microchannel condenser coils allow the chillers to achieve higher capacities, but with a lower refrigerant charge than previous models. Swegon says this means the chillers can deliver high efficiency operation from a smaller footprint and also offers compact models for use where space is at a premium.
Also available are modular free cooling versions, designed for year-round cooling and taking advantage of the UK’s temperate climate to reduce energy costs.
BlueThink controls manage the operation of the inverter, compressor speed and variable valve ports. This allows for closely controlled part load operation of the chiller to maximise energy savings and extend operating life as well as remote monitoring for service and maintenance purposes.
The chillers have two levels of inverter control – full inverter and hybrid – depending on the performance needed for the project in hand. Low noise versions are also available.
