New advanced LGR technology (Low Grain Refrigerant)


How a Phoenix R200 works

The Phoenix R200 uses LGR (Low Grain Refrigerant) technology to remove more water from the air. In order to better understand LGR technology, let’s first look at how a conventional refrigerant dehumidifier works.


Conventional Dehumidifiers

A conventional dehumidifier draws moisture-laden air across a set of super-cooled coils. As the air passes over, its temperature drops below dew point and water condenses on the cold coils. The dry air is reheated and exhausted to the room to collect more moisture.


How a LGR works

A dehumidifier with LGR technology improves on con-ventional refrigerant designs by pre-cooling the air to increase water removal efficiency. The Phoenix R200 uses a special air-to-air heat exchanger to cool down the air before it passes over the super-cooled coils.
This allows the R200 to create lower specific humidity (i.e. drier air) that helps remove bound moisture from structural materials. As an added bonus, the
air-to-air heat exchanger does not use any energy
so that amp draw stays low.


What is the difference in performance between an LGR and a conventional refrigerant dehumidifier?

A LGR dehumidifier will return wet materials to acceptable pre-loss condition faster than a conven-tional refrigerant. In general, one LGR can dry out a room in less time and more thoroughly than multiple conventional refrigerants. Although multiple conven-tional dehumidifiers will process a higher volume of air, they are unable to lower the specific humidity as far as an LGR dehumidifier.

The Phoenix R200 produces very low specific humidity that pulls bound moisture out of structural materials for more effective drying. With LGR, you can start and finish a job with the same dehumidifier.


How does the Phoenix R200 LGR function in low humidity conditions?

The Phoenix R200 performs extremely well in low humidity conditions thanks to its LGR technology. The LGR technology in the Phoenix R200 uses a special air-to-air heat exchanger system to help bring the air closer to dew point temperature before it passes over the super-cooled evaporator coils. This allows more “coil energy” to be spent on water removal instead of cooling the air to dew point. This extra efficiency makes the Phoenix R200 perfectly suited for low humidity conditions.


Should my next dehumidifier purchase be an LGR or a conventional refrigerant dehumidifier?

You should seriously consider making your next dehumidifier purchase one with LGR technology. Drying technology has progressed and an LGR dehumidifier offers you greater drying ability than previous designs. The Phoenix R200 is a significant leap forward in dehumidifier design.
