Suitable for a busy butchery / small cutting plant
A 120-litre tank with integral heat exchangers with 6kW capacity
A busy butcher will have a constant demand for hot water which means a constant energy demand cost. It will usually have a small boiler providing hot water either on demand or heating a small tank ready for use. A DK heat recover system would be fitted up stream of the boiler to provide the unchanged heating system with pre heated water at 50°C. This means that either the existing boiler will have either nothing to do or operate at a lighter load. Keeping the original boiler in place will reduce installation costs and provide a backup should the refrigeration system be switched off for any reason.
A 6kW system with a 120-litre storage tank would produce 120 litres of hot water at 50°C every hour to cope with the continuous water demand and end of day clean down requirements.
Assuming a 6-day operation with an average of 10 hours per day the system has the capability to save 20,000 kWh of heat energy (more if oil or gas is being used).
