Ammonia System High Side Float Regulators

High pressure float regulators offer a simple, mechanical solution to expand refrigerant from the high to the low pressure side. 

• Highest safety and no operation failures, because the High pressure float regulator acts solely mechanically.
• Simple and robust overall concept of the entire refrigeration system without the need of additional cables or controls.
• Efficient operation, because the refrigerant is passed from the internal float when needed. Therefore low condensing temperatures without additional controls can be realized.

In contrast to an operation with expansion valves neither sub cooling of the condensate nor desuper heating of the refrigerant vapour at the evaporator outlet is required.
