Albert Bartlett,
The Customer
Albert Bartlett is a progressive family business and brand, established in 1948 and dedicated to providing tasty, wholesome food. The Company have been farming potatoes with their trusted growers for over 60 years and now supply over 20% of the UK’s fresh potatoes.
Their potatoes are grown across the UK from the far north of Scotland through the country to Cornwall and across to Northern Ireland and the Island of Jersey.
Albert Bartlett has invested substantially in infrastructure since 2003 across three busy production sites in the UK. More recently the Airdrie site was earmarked for expansion to meet the growing demand for their new chilled potato products, which they supply to some of the UK’s major retailers and food service customers.
The Brief
To provide the client with a full design, installation and commissioning of a complete energy‐efficient ammonia/glycol (HFC free) cooling system to enable them to meet the demands of their new chilled potato products.
This was an interesting project, providing a full-service solution that meets the needs of such increased demand for chilled potato products.

The Solution
JDI’s solution features Sabroe low temperature screw compressor, Sabroe high temperature reciprocating with a speed range of 500-1500rpm, evaporative condenser, two spiral freezers to deliver mash potato in sealed trays, 16 glycol air coolers and three end suction glycol pumps, each with a flow rate of 242m3/hr.
Rejected heat from the drive systems in the refrigeration switch room needed to be managed, with another glycol air cooler sized at 20kW installed to ensure that a room temperature of 20oC to 25oC is maintained.
Equipment capable of operating at very low temperatures was a key consideration of the brief as well hygiene associated with food production.
“This was an interesting project, providing a full-service solution that meets the needs of such increased demand for chilled potato products. Committed to helping clients through all their cooling system needs, we aim to truly understand the business and work in partnership to deliver the most effective solutions,” comments Mark Culley, JDI Managing Director.
In collaboration with JD Cooling Group’s other business units, the automation system consisting of two network protocols: Ethernet and Profibus, was designed and installed by JDI Controls. As JDI standard the electrical automation system has been designed to not have a single point of failure and specific software that helps to optimise the running conditions of the complete system.
