Heat recovery from three 125 HP oil free air compressors and heat of compression air dryers, used for preheating boiler feed water and CIP process.

IMEC just completed a Heat Recovery system, featuring plate frame heat exchangers, for a manufacturing facility of Cedars Mediterranean Foods.

Assessment and Recommendation

The facility team at Cedars had purchased new Atlas Copco ZR 90 VSD-FF air compressors that offered a Heat Recovery option allowing the compressors to generate Hot Water. We proposed to provide a series of Plate Frame Heat Exchangers to reclaim this heat by pre-heating the boiler feedwater. The first Heat Exchanger captures the low grade heat from the MD Air Dryers and the second Heat Exchanger captures the high grade heat from the Air compressor circuit. An additional heat exchanger was added to preheat water for the CIP process.

Energy Savings

The forecasted savings based on the Air Compressor load profile is 30,709 therms assuming 8,640 hours/year operation. Based on a cost of $1.00/therm, the total cost savings is more than $30,000 per year. This Energy Efficient Measure (EEM) qualifies for a National Grid incentive.
