Pumped Ammonia Cold Store — Essex

This deep-freeze cold store project in Essex required six large ceiling mounted coolers capable of maintaining a store temperature of -24°C using a pumped ammonia refrigeration system.

HC Coils designed each cooler to maximise air distribution across the full depth of the store. Honeycomb air straighteners were specified on every unit to ensure the cold air throw reaches the back of the storage area — critical for maintaining uniform temperatures and preventing hot spots that could compromise stored products.

All six units were fitted with EC energy-saving fans, reducing the facility's long-term energy costs while also lowering noise levels in the working environment. The easy-clean feature was included across all coolers to support the client's maintenance regime.

The project was delivered on time and within budget, with all coolers manufactured to the exact specifications required for this demanding ammonia application.
