Services: Turnkey Refrigeration Package
We provided a customised solution for a global veterinary health care provider for their new facility where they develop vital vaccines and antibiotics for animal health. This specialist project required exceptionally precise temperature control, requiring us to leverage our expert skills to find a suitable solution that would meet our client’s requirements. The client set us a brief to deliver:
The coldstores needed to operate within strict temperature tolerances, provide 100% standby and back-up and be energy efficient.
With a total of 4000m3 of chilled cold storage, including 400m3 freezer storage, this was a large-scale project with a strict schedule. We successfully completed this project two weeks ahead of schedule and the system is now running smoothly and well within the 1C temperature fluctuation requirement.
We delivered a full turn-key refrigeration package from designing and modelling the cooling system, to manufacturing the refrigeration packs, installing and commissioning the whole system, and the ongoing service and maintenance.
Two dual temperature refrigeration packs were connected to two roof-mounted condensers. To prevent unconditioned ambient air from entering the main cold room areas, the airlocks were fitted with interlocking roller doors. An isolation switch fitted to one of the chilled holdings delivers chilled storage at 12C or ambient, without it affecting the main system.
We managed all aspects of the refrigeration installation, including the sign-off and validation of associated mechanical and electrical services, ensuring everything was delivered correctly, was of the highest quality, and met all health and safety and documentation requirements.
The brief included the installation of a complex control system which would provide 100% back-up resilience, as even a small temperature variance would compromise the products being stored. To achieve this, we designed and installed the plant and control system so that each pack could maintain the coldroom set point temperatures independently of the other, should one fail because of a major mechanical fault or gas leak. To do this we utilised split evaporator coils with twin controls that would automatically transfer the full connected load to the other pack if a fault is detected. The split units were also timed to alternate on a weekly basis to ensure each one maintains optimum operational efficiency.
Six large scale coldstores were required for this project, with the largest measuring 27.3m (L) by 11.2m (W) by 10.5m (H). The sheer scale of these coldstores presented a logistical challenge and working at this height required specialist safety measures. We have extensive experience in managing projects at height, and so to ensure the health and safety of those working on the installation, we used high-level scaffolding, a dedicated access lifter, a buddy system with spotter and two-way radios.

“The level and extent of commissioning data required to satisfy pharmaceutical validation criteria is the highest possible, and Space Engineering Services delivered the specified tight temperature control parameters and the stringent and extensive handover pack information. We wouldn’t hesitate to recommend their performance and look forward to working with Space Engineering Services again.” Richard Sutton, PJ Hegarty (Principle Contractor)
