LGR1800 Portable Dehumidifier 230 volt
with remote monitoring capability (F432i)
The Dri-Eaz® LGR1800 dehumidifier reduces humidity in enclosed structural environments
by removing water vapour from the air. The LGR1800 is engineered for improved operating
performance within lower humidity environments. With a rugged, durable and highly port-
able design, the LGR1800 is ideally suited for water damage restoration, structural drying,
construction, and other applications requiring temporary, high-performance
dehumidification. With built-in humidistat control, the LGR1800 is ideal for environments
that require longer term humidity control, museums, server rooms, etc.

INTRODUCTION
Dehumidifiers reduce humidity in enclosed structural
environments by removing water vapour from the air.
With proper use, the LGR1800 can help dry carpet,
carpet pad, floors, walls, building contents and more.
Using dehumidifiers can also help prevent secondary
damage caused by high humidity. For best results, use
the LGR1800 with Dri-Eaz TurboDryer airmovers placed
around the perimeter of the room. Airmovers help to
distribute heat energy, which accelerate the release of
moisture from wet surfaces into the air.
How the LGR1800 dehumidifier works
Dri-Eaz refrigerant dehumidifiers operate by pulling
moist air in across a very cold evaporator coil. The
moisture in the air condenses on the coil and drips into a
catch basin. The water collects in a tray and is pumped
out through a hose. In certain conditions, the machine
operates in defrost mode, warming any frost
accumulated on the evaporator coil back into water. LGR
(Low Grain Refrigerant) dehumidifiers have better heat
exchange and defrost abilities than regular refrigerant
dehumidifiers, and are able to continue removing
moisture in drier environments.
Remote Monitoring Option
Your Dri-Eaz distributor can modify the LGR1800 to
work with the HygroTrac Remote Monitoring System
(purchased separately). HygroTrac lets you view drying
environment conditions and equipment performance
from any Web browser. Contact Dri-Eaz on +44 (0)1908-
611-211 for more information about this option.

      Jose LeonardAug 15, 2025
      If your Dri-Eaz Dehumidifier is running but the room isn't drying, it could be due to several reasons. First, allow more time for drying. Second, increase air movement in the room using air movers. Finally, reduce moist air infiltration into the room.

    Why Dri-Eaz LGR1800 collects too little water?
    • H
      Hailey FisherAug 20, 2025
      If your Dri-Eaz Dehumidifier is collecting too little water, it may be due to several factors: - The room air might be too dry, check humidity with a hygrometer. - The room temperature might be too low, increase the room temperature. - The airflow through the unit might be restricted, check the filter and coils and clean them if necessary.
