The Difference between LGR and Conventional Dehumidifiers

Why SERVPRO The Difference between LGR and Conventional Dehumidifiers Our professional-grade equipment helps with the toughest of jobs and produces amazing results for our clients.

As a water mitigation company, SERVPRO of West Erie County uses professional-grade equipment to help with the toughest of jobs and produce amazing results for our clients. Having a powerful dehumidifier is a very important tool to have. But what type of dehumidifier do our customers actually need?

That decision usually comes down to two types; Low-Grain Refrigerant (LGR) and Conventional dehumidifiers. Of these two, LGRs are more efficient. They incorporate an extra step in the cooling process which leads to lower air temps in the moisture-filled space.

LGR dehumidifiers use three different types of precooling systems:

  1. Heat Pipe System – this system collects hot air, cools it, then heats and evaporates it once more. This process is repeated over and over with the aim of removing moisture from the air.
  2. Thermal Siphon System – this system uses a stacked hot and cold coil to perform the same type of repeated cycle as the heat pipe system.
  3. Air-to-Air Heat Exchanger – this system uses air to transfer heat rather than liquid refrigerants.

Conventional dehumidifiers condense water vapor by passing air over refrigerated coils. They also contain a heat pipe that prevents frost from forming. When compared to LGR dehumidifiers, Conventional models are not as efficient at removing moisture and drying environments with large volumes of water.

At SERVPRO of West Erie County, we take pride in having state of the art equipment and technology that help our professionals do their jobs and  deliver the greatest results. If you are experiencing water damage, call SERVPRO Of West Erie County at (814) 806-1987.
