Heat Hog 500

Suitable for a small food manufacturer

A 500-litre tank with integral heat exchangers with 36kW capacity

Food manufacturers have a constant demand for hot water during production but with substantial peaks at product change overs and end of shift day clean downs. Hot water production using a heat recovery system is usually uniform so to accommodate peaks requires a greater storage capacity is required. 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 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 36kW system with a 500-litre storage tank would produce 720 litres of hot water at 50°C every hour to cope with the continuous water demand and 500 litres of water ready to cope with the peak demands

Assuming a 5 ½ -day operation with an average of 16 hours per day the system will save 133,000 kWh of heat energy when using electricity for heating (more if oil or gas is being used).

Note: Savings are calculated using only 75% of the systems capability
