The simple and cost-efficient solution for refrigerant expansion.
The mechanically operated WITT HP float regulators helps you to save energy while offering a high level of safety without a need for additional electrical cables and controls.
The principle is as simple as it is effective. When the refrigeration capacity increases will the liquid level in the HP float regulator rise and the refrigerant expands via the entirely mechanical operated float valve orifice opening. Due to this expansion (pressure loss) in the outlet opening there will be a liquid-vapour mixture behind the HP float regulator that is drained back to the surge drum. A high pressure receiver is normally not required.
The continuous expansion of the HP float valve eliminates pressure fluctuations and flash gas is reduced. Therefore the electrical power consumption of the compressor is reduced as well.
The flooded operation with HP float valves can take advantage of lower ambient temperatures during the colder seasons with lower condensation temperatures, independent of the control system. And with a 5K lower condensation temperature you already save about 13% electrical energy consumption.
