Carrier AquaSnap® 30RBP air-cooled scroll chillers operating on lower global warming potential (GWP) refrigerant R-32 are providing high-efficiency cooling and heating for the world’s largest vertical farm in Lydney located in the Forest of Dean district in Gloucestershire, operated by Jones Food Company.

The vertical farm, the size of seventy tennis courts, offers 148,000 square feet of growing space for stacking crops 15 layers high and is expected to supply 1,000 tonnes of fresh produce a year to UK supermarkets.
Carrier is a part of Carrier Global Corporation, a global pioneer in intelligent climate and energy solutions.
heating and cooling solution
The chillers specified needed to be compatible with Brooktherm’s control system
Contractor Brooktherm Refrigeration Ltd was tasked with providing an HVAC solution capable of delivering a constant supply of efficient heating and cooling to the pressurized warehouse. The chillers specified needed to be compatible with Brooktherm’s control system.
“One of the key challenges was the requirement to achieve four different temperature and humidity set points,” said Ben Doherty, Projects Coordinator, Brooktherm Refrigeration Ltd. “With the support of Carrier, we achieved them all.”
AquaSnap 30RBP air-cooled scroll chillers
Carrier recommended its flexible and compact AquaSnap 30RBP air-cooled scroll chillers with refrigerant R-32, which operate from -0oC up to +48oC, and come with Greenspeed intelligence® variable-speed pumps to reduce pumping energy consumption by up to two-thirds.
The innovative solutions support Carrier’s ESG goal of helping customers avoid more than 1 gigaton of GHG emissions by 2030.
Energy savings
The Carrier chillers have a heat recovery system that enables waste heat to be captured and used for various applications
The Carrier chillers have a heat recovery system that enables waste heat to be captured and used for various heating applications on-site, saving energy while maintaining optimum growing conditions.
The cultivation warehouse is served by two HVAC plants, one on the north side and one on the south side, each equipped with two Carrier chillers, delivering a total of 2.2 megawatts of cooling and heating to the growing room.
sustainable new approach
“This exciting project is an efficient and environmentally responsible way to produce food and Carrier was delighted to be part of such a pioneering, sustainable new approach to growing the nation’s food,” said Paul Hill, Regional Sales Manager, Carrier UK.
“The HVAC plant was fully commissioned summer of 2023, and by October the entire growing area was fully planted, allowing the operator to harvest a tonne in weight of basil and leafy greens every 19 days.”
Vertical farming
“With our new facility, we further accelerate Britain’s position as a world pioneer when it comes to vertical farming,” said James Lloyd-Jones, Chief Executive Officer, of Jones Food Company.
“We already supply thousands of British retail stores with asil grown in our first facility in Lincolnshire, but our Lydney site is three times bigger and will allow us to supply a greater range to more stores.”
