Food Manufacturer – Heat Recovery

Project Details

This case study demonstrates how previously Denco have completed the design and manufacture of an Energy Recovery module coupled to a Variable Speed Drive Air Cooled Compressor via a heat exchanger on the oil lubrication circuit. The oil lubrication circuit operates at circa. 85°C and can produce hot water and up to 80% of the compressors total capacity.

This particular operation utilises the hot water produced to heat up the inlet to the onsite mains water header tanks through a heat exchanger thus transforming the header tanks into hot wells. This hot well was then able to continually supply the plant with hot water for wash downs amongst other applications reducing the sites gas consumption.

The installation of this equipment saved the user circa £20K per annum with an equipment payback of only 9 months.
