Prep Area & AHU

DSI Foods approached RS Refrigeration to help increase their production capacity, including a large positive pressure assembly area.

To cool this area, RS Refrigeration supplied six Rivacold dual discharge evaporators with a combined cooling capacity of 36kw to maintain a stable 10°C within the production area.

To pressurise the room, we supplied a custom-built total heat exchanger with additional DX cooling and heating. Using the latest inverter heat pump equipment from Daikin Air Conditioning we were able to eliminate up to 100% of the additional heat load from the incoming supply fresh air.

To guarantee the highest levels of hygiene we supplied industrial grade pre filters and HEPA filtration within the bespoke air handling unit and by ensuring a 4:1 ratio of supplied air to return we were able to provide a positive pressure to the room to prevent any unfiltered air ingress.
