The Bohnmizer
®
System
The bohnmizer® system is a complete factory furnished commercial refrigeration split system designed to operate
properly regardless of climatic conditions. As the ambient temperature falls below 75°F, the head pressure is
allowed to decrease in direct relationship to the ambient.
The heart of the system is the bohnmizer valve, whose design allows the proper amount of refrigerant to flow to
the evaporator irrespective of the valve inlet pressure. The bohnmizer valve also responds very rapidly to changes
in suction temperature, which assures the maintenance of low superheat, regardless of the ambient temperature.
The bohnmizer system concept results in operational energy savings, increased compressor life, reduced
refrigerant costs and less maintenance expense.
