Services: Refrigeration Design, Plant and Cold Room Supply, Installation and Service & Compliance
Bidfood required a refrigeration solution for their new distribution centre in Chepstow, South Wales.
The site was an existing, un-occupied distribution centre which would be demolished back to its structural steelwork, then rebuilt and refurbished.
Bidfood approached us with a requirement for two very large cold rooms, one to be used as a -25 ⁰C freezer and the other a + 2⁰C chiller.
Thanks to our three decades of experience of delivering refrigeration solutions in industrial environments, we were able to call upon our extensive experience to devise a bespoke solution for Bidfood that met all of their requirements.
We designed a complete solution for Bidfood to meet their requirements, which were:
The freezer plant needed to be split into two identical systems for redundancy and plant failure purposes. The freezer solution was a DX type using refrigerant R407A split into two identical systems. In addition, three Sabroe screw compressors were supplied, selected for their exceptional reliability, low running costs and ease of service. Two of the compressors would be continuously operational with the third acting as a swing machine for greater resilience in the event of a system failure. The heat rejection was accommodated by two air cooled ‘v block’ condensers and eight heating and cooling evaporators were mounted on steel at high level on the rear wall of the cold rooms.
For the chiller, two 150 kW fluid chillers were installed with a hydronic module incorporating a water circulating pump, expansion tank, water flow switch, pressure gauges, purge valve and throttle valve. We also installed eight heating and cooling glycol coolers, mounted on steel at high level and connected to a common glycol flow and return chilled water system. Further cooling was provided by two fluid chillers located externally.
The refrigeration solution was completed in five months, alongside other refurbishment works that were taking place at the same time. After successful commissioning and executing performance checks, we handed over the system to Bidfood. On the basis of our performance, we were selected by Bidfood to be their refrigeration service partner to carry out all servicing and compliance checks to keep the systems running efficiently.Get in touch
