UNPACKING
Carefully remove the RM40-SH dehumidifier unit from its transit box and
visually check for signs of transit damage. If there is evidence of damage DO
NOT attempt to operate the unit, call your supplier for advice. Do not discard
the packing; it will be useful when transporting the dehumidifier unit in the
future.
INTRODUCTION
The RM40-SH industrial dehumidifier removes moisture from the air through
the refrigeration process.
The RM40-SH is basically comprised of:
A) A compressor
B) A refrigerant evaporator coil
C) A refrigerant condenser coil
D) One circulation fan
E) A drain tray for collecting and disposing of condensed moisture
F) A solid state timer for hot gas defrost cycle
G) An adjustable membrane-type humidistat
H) A cabinet to house the above components
The fan draws the moist air through the cold evaporator coil which cools the
air below its dew point. Moisture forms on the evaporator coil and is collected
in the condensate tray which is equipped with a permanent drain. The cooled
air then passes through the hot condenser coil where it is reheated using the
same energy removed during the cooling phase plus the additional heat
generated by the compressor. The air is, therefore discharged from the
dehumidifier at a slightly higher temperature with a lower absolute humidity,
than that which entered. Continuous circulation of air through the dehumidifier
gradually reduces the relative humidity within the area.
The RM40-SH dehumidifier is a rugged reliable drying unit designed to
operate effectively over a broad range of temperature and humidity conditions.
A powerful and reliable active hot gas defrost system, controlled by an
electronic timer, guarantees positive de-icing, thereby optimizing operation at
low temperatures.
The unit incorporates a welded steel chassis and is finished in an epoxy
coating for resilience to damage caused by rough handling.
The RM40-SH dehumidifier is fitted with an adjustable humidistat to enable
you to select the level of dryness.
