Carrier claims new benchmark with screw chiller range


23 February 2018
Carrier says its new range of variable-speed screw chillers achieves exceptional levels of seasonal efficiency.

The AquaForce Vision 30KAV with Greenspeed intelligence, with a first phase covering cooling capacities from 500 kW up to 1100 kW, is equipped with variable-speed screw compressors and variable-speed fans – AC as standard and EC as an option – as well as optional variable-speed pumps.

​It automatically adjusts the cooling capacity and water flow to match the needs of the building or process load variations. The result is optimal operation at both full load and part load. This new range of chillers has a SEER of up to 5.5 in cooling mode, and an Energy Efficiency Ratio (EER) of up to 3.49 at full load. 30KAV offers energy efficiency up to 40% higher than the 30GX range with the same footprint.
Product Manager William Doll said: “Our engineers have developed state-of-the-art technologies to exceed the European Ecodesign energy performance standards by 30%. AquaForce Vision 30KAV sets a new benchmark for efficiency, compactness and intelligence.”

Operating at external temperatures ranging from -20°C up to 55°C and negative water temperatures, 30KAV is an ideal solution for a wide range of sectors. From large-scale office buildings, hotels and healthcare facilities to data centres and industrial projects, 30KAV meets the most demanding expectations in terms of energy efficiency and savings, whatever the climate.

Features include:
  • New 06Z variable-speed screw compressor
  • Sixth generation of Flying Bird Fan with EC motor
  • Third generation of Novation micro channel heat exchangers with a unique W coil design built in a single piece

The AquaForce Vision 30KAV also features Touch Pilot control with a colour touch screen user interface in 10 languages and functions, such as Carrier’s smart energy monitoring to provide customers with smart data and optimise energy savings under real conditions. Furthermore, the 30KAV can be connected to Carrier’s remote monitoring centres where Carrier engineers can analyse data and optimise chiller performance.

With sound levels of 90 dB(A) during operation, this new range has particularly low sound levels compared to its previous generation.    
The AquaForce Vision PUREtec 30KAV-ZE version, designed exclusively for ultra-low global warming potential (GWP) refrigerant HFO R-1234ze, will be available in 2018.

The range will also be extended up to 1800 kW cooling capacity with premium technologies and additional options.
