Intelligent Hands Off Heat Pump Systems
A potato farm in Shropshire process 36,000 tonnes of potatoes per annum at their plant. A 3992kW Heat Chill Heatpump has been installed with 30,000km of in-ground pipework to service: the pre-heating of the air onto their Alvan Blanche Grain Dryer, warm water for the potato washer, warming of the grading shed and washdown, as well as Heat Chill Box drying floor.
This solution is fully automated to provide simultaneous heating and chilling, maximising efficiency via the remote access control system.The chilling by-product achieves 80% of the annual kW usage as a secondary back up to the existing chillers in the 12 potato stores as well as pre chilling and conditioning the grain prior to storage.
