Energy & Heat Recovery Ventilation SystemBecause many laboratory facilities require 100% makeup air for workstation environments, Neurogen Corp. in Branford, Connecticut, looked for ways to cut its high energy costs at a new facility for chemical research. Tri-Stack® systems were used for laboratory workstation fume hood exhaust to eliminate re-entrainment possibilities into the building’s ventilation system; heat recovery coils filled with a solution of glycol and water at the 20,000 sq.ft. building extract heat from workstation fume hood exhaust before it is discharged above the roof-line, reducing the need for natural gas to pre-heat (or pre-cool) makeup air. The Tri-Stack® heat recovery system increases intake air temperature by 10° F, resulting in a 30% reduction in heating energy costs.
