Dessicant
Dry Cabinets
The
Tongrun Dry Cabinets are used for the dehumidification
process controlled at a constant temperature of components
or equipment Moisture Sensitive Device - MSD in a
range between 10 and 20% RH (FCD) and 1 and 10% RH
(FCDE).
The main characteristic of these products is the possibility
to work in the absence of molecular nitrogen (N2),
even if there is an option to have the controlled
introduction of nitrogen in the case of frequent openings
of the cabinet.
The desiccant used in the cabins is particularly suited
to the task and, in normal operating conditions, for
a period of 10 years or more without the need for
replacement.
The system is controlled electronically and is able
to maintain an extremely low level of relative humidity
of up to 1% RH .
The cabins are designed to eliminate defects resulting
from moisture, such as micro-cracks, depaneling, delamination,
etc ..., on Moisture
Sensitive Device - MSD.
Useble
in Elettronica,
Optic, Photografy
and Laboratory,
equipment are fully autonomous and controlled with
excellent quality / price ratio and do
not require molecular nitrogen (N2)!

|
The
Tongrun dehumidification systems are cabinets
provided with a special desiccant product ( free
exchange ), which maintains the internal environment
with a relative humidity range of 1-60 % RH. The
desiccant used in our cabins is particularly suited
to the task and , in normal operating conditions
, is suitable for a period of 10 years or more
without the need of replacement.
The cabins are equipped with high efficiency dehumidification
unit controlled mechanically and able to achieve
extremely low levels of relative humidity .
When an object that contains moisture , even if
in small quantities , is positioned in a cabin
of dehumidification , the humidity particles are
slowly released and absorbed by the object itself
from the desiccant . In practice, given that the
level of relative humidity is very low , the air
present inside it acts as a magnet that attracts
the particles of moisture present in the object
and pulls out dropping into the air outside of
the cabin . This process continues until a balance
is reached between particles of moisture still
present in the object and the level of humidity
of the cabin, until the desiccant becomes saturated.
When you reach equilibrium or saturation of the
desiccant, a "refresh" process is activated,
closing the shutters inside the cabin , opening
the external ones and removing all the moisture
collected by the desiccant.
|
The
desiccant is refreshed by heating, allowing trapped
moisture to come out as steam (H2O) through vents that
are on the back of the cabinet. Once you have completed
the "refresh" the unit is ready to seal the
vent outside and re-open inwards to continue dehumidification.
