Carrier has launched a new range of compact process cooling chillers on ultra-low global warming potential HFO refrigerant, R1234ze.
The AquaForce Vision 30KAV air-cooled, variable-speed screw chillers are optimised for industrial applications such as food manufacturing, pharmaceuticals, chemicals, plastics, metal industries and applications requiring ultra-reliable cooling to -12°C.
They include two innovations to help support mission critical processes:
- Ultra-fast capacity recovery: In the event of the chiller power supply being interrupted, this enables immediate chiller restart following power restoration with 100% capacity recovery within one minute, minimising the risk of damage to the process or products being cooled.
- Boosted hybrid total heat recovery: this allows more heat to be recovered during the winter, further increasing efficiency and reducing running costs.
The chiller is available in four sizes, spanning capacities from 280 kW to 800 kW into -4°C/-8°C medium temperature process cooling and from 530 kW to 1300 kW into 12/7°C high-temperature process cooling or comfort cooling. The unit’s carbon footprint is minimised due to its combination of ultra-low GWP HFO refrigerant, a 40% reduction in refrigerant charge due to use of Novation micro-channel heat exchangers and outstanding energy efficiency delivered by the onboard variable speed drive, which precisely matches compressor speed to load. The chiller's compact design, with a physical footprint one-third less than standard 30KAV chillers, enables it to be deployed where space is tight without compromising performance.
"The new chiller has been designed and optimised for use in a wide range of process cooling applications," said William Doll, Europe marketing manager, chillers and heat Exchangers, Carrier. "It delivers high seasonal energy efficiency, a low environmental footprint, excellent reliability, safe operation and a very low total cost of ownership over its lifetime.”
For contractors and service staff, the 30KAV has been designed to be quick and easy to install and maintain. Its compact dimensions give ready access in areas where space is tight, while its electrical system ensures compatibility with earthing requirements in different segments. In addition, use of smart energy monitoring and onboard leak detection enable chiller operation to be monitored in real-time.
