Carrier Launches HFO R-1234ze Chillers for Industrial Process Applications
Carrier has introduced the AquaForce ® Vision 30KAV with PUREtec™ refrigerant , a new line of high-performance , compact process cooling chillers with ultra-low global warming potential ( GWP ) refrigerant R-1234ze .
The new chiller line is optimised for industrial processing such as food manufacturing , pharmaceuticals , chemicals , plastics , metal industries and applications requiring ultra-reliable cooling up to -12degC.
Carrier ’ s AquaForce Vision 30KAV aircooled , variable-speed screw chillers are designed to minimise energy consumption and impact on the environment while maximising performance and ease of installation and maintenance . Energy efficient solutions like the AquaForce 30KAV chiller support Carrier ’ s 2030 Environmental , Social and Governance ( ESG ) Goals to reduce its customers ’ carbon footprint by more than 1 gigaton .
The chiller is available in four sizes , spanning capacities from 280 kW to 800 kW into -4degC/ -8degC medium temperature process cooling and from 530 kW to 1300 kW into 12 / 7degC hightemperature 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 .

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 .
“ 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 mission critical applications , such as process cooling and food manufacturing , Carrier has developed an ultra-fast capacity recovery option . In the event of the chiller power supply being interrupted , the recovery option 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 .
All 30KAV models can also be equipped with an innovative boosted total heat recovery option that allows more heat to be recovered during the winter , further increasing efficiency and reducing running costs . The heat recovery option uses a hybrid design that harnesses the benefits of both serial and parallel design approaches . When heat reclaim is activated , the air-cooled coils are automatically isolated to reduce the impact of cold ambient air on the heat capacity that can be recovered from the water-cooled heat exchanger .
This option increases heat recovery by 25 % at nominal load with 35 C outside air temperature , and by 100 % or more when the chiller operates with low outside air temperature , compared with the traditional serial-only approach to heat recovery . The cooling capacity of the chiller is also slightly enhanced in heat recovery mode . Due to its compliance with European Ecodesign Directive requirements , the AquaForce 30KAV can also be used in comfort cooling applications .
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 .
For total peace of mind and to minimise running costs , building owners and facilities managers can opt for one of Carrier ’ s BluEdge™ service support options to keep chillers operating at peak performance and efficiency throughout their life cycle . The service support uses Carrier ’ s advanced cloud-based diagnostics platform within BluEdge to monitor and optimise chillers remotely , and via site visits by highly experienced staff if required . e
