WASTE HEAT AMMONIA WALK-IN FREEZERS
Turn recovered heat into dependable subzero cooling
MTD integrates heat-driven ammonia-water absorption refrigeration for cold storage, process cooling and freezer applications. The system replaces the large electric compressor with a thermal cycle powered primarily by recovered heat.
Design Service Life*
Long-life thermal refrigeration design
LOWER ELECTRICITY USE. LOWER PEAK DEMAND. LONG ASSET LIFE.
Make Waste Heat Work Harder
Recover available thermal energy and put it to work supporting dependable industrial refrigeration.
100-ton example
At design load
When waste heat is available
Benefits for Facility Owners
Uses otherwise-wasted exhaust, jacket-water, steam or process heat
Eliminates the large refrigerant compressor and its overhaul cycle
Cuts annual electrical consumption and utility demand charges
Produces subzero cooling for freezers and industrial processes
Low vibration, quiet operation and few major moving components
Natural ammonia refrigerant with zero ozone-depletion potential
Expandable from tens to thousands of refrigeration tons
How Waste Heat Becomes Cold
A four-stage thermal process converts recovered heat into useful refrigeration.
RECOVER
Capture usable heat
SEPARATE
Drive ammonia from solution
CONDENSE
Reject heat outdoors
FREEZE
Expand and absorb freezer heat
