ABOUT
DEHUMIDIFIERS
• A machine that removes excess
moisture from the air.
• Industrial dehumidifiers are built to
be transported and used in several
hard-wearing locations.
• Commercial and industrial
dehumidifiers reduce mold,
condensation dripping from pipes or
windows, and eliminate musty smells.

Moisture control is a great concern from product manufacturing to
packaging, and from shipping to storage.
Some applications for humidity and moisture control in pharmaceuticals
relate to microbiological considerations, while many applications relate to
processing in order to achieve correct moisture levels that will facilitate
the filling of capsules, tablet forming, and packaging.
For example, gelatin capsules are often monitored closely for moisture
content to allow them to be sufficiently supple for filling without cracking
or breaking in the manufacturing process.
Effervescent powder manufacturers must maintain tight control of the
plant's humidity in order to avoid moisture regain in the powder.
PHARMACEUTICAL
APPLICATIONS FOR DEHUMIDIFIER MACHINES

www.messungautomation.co.in
Dehumidifier machines allow the automotive industry to
maintain temperature and humidity, even to the most precise
specifications and are used in a variety of applications.
Complete cars, engines and parts are subjected to a large
degree of testing in environmental chambers and wind tunnels.
It enables automotive manufacturers to simulate any
environmental condition with dehumidification systems that can
deliver dry air.
AUTOMOTIVE
APPLICATIONS FOR DEHUMIDIFIER MACHINES

www.messungautomation.co.in
Dehumidifiers help create the best conditions to convey, cool, freeze, dry and cure
foods, right through to packing and storage.
This guarantees consistent quality, cost savings and increases throughput.
Exact regulation of temperature and humidity is necessary in the production of
many foods.
The external climate may vary but, in the production process, the climate must be
constant.
From production processes such as pasta cutting, conveying belts, tunnel freezers,
blast freezers, spiral freezers or cold stores, to sugar silos conditioning, product
transportation and storage, it is possible to achieve important cost savings by
controlling relative humidity.

THE SOLUTION:
Messung engineers studied the machine and its requirements, and came
up with a solution consisting of
• NX-ERA XPRESS XP325 PLC controller
• 4.3 incheHMIs HMI
The dehumidifier control system is based on a PLC, which comprises
• a programmable logic controller
• a transmitter
• a signal input part
• a contactor
• an
• an extended communication module.
Control instructions can be obtained from a digital input terminal of the
PLC, the HMI or a top level computer. The system running state can be
displayed on a digital output terminal of the PLC and the HMI.

www.messungautomation.com
THE SOLUTION:
The acquired humidity and temperature
signals are converted into usable frequency
signals and accessed to a PLC high-speed
counting input terminal which performs
timer counting for obtaining a sampling
value.
The HMI and the extended communication
module facilitate the realization of local
monitoring and controlling as well as remote
computer monitoring and controlling on the
dehumidifier control system.

ADVANTAGES OF THE
DEHUMIDIFIER CONTROL
SYSTEM:
• low cost
• convenient use
• flexible programming
• high reliability
• strong anti-interference performance
• powerful Human-machine interface functions
• powerful communication functions
• easy to integrate in an on-site bus control system
as an intelligent node.

A powerful micro PLC (Programmable Logic
Controller) developed by Messung, leading micro
PLC manufacturer - for entry-level applications.
Packed with advanced features
NX-ERA Xpress Mini PLC delivers high-speed
processing power in a compact design with
embedded I/O.
The micro PLC system can be easily expanded
through CANopen using the Remote I/O
Modules - a great advantage for OEMs with needs
of small, scalable applications.

SAFETY:
It uses only a minimal amount of power
and has safety features to protect you in
case it overheats or overturns. Condensate
dehumidifiers are used in refrigerators to
collect water, called condensate, which is
normally grey wool and can be reused over
time for industrial purposes.
CONFORMAL COATING:
ensures integrity even in harsh
environments.
BENEFITS FOR THE CUSTOMER
SAVINGS:
If you can reduce your air conditioning use
by only an hour a day because of the
action of a dehumidifier, you will save
around INR1520 a day… and you will
probably manage to reduce your use much
farther.
Programming and configuration environment based on IEC 61131-3 standard:
the global standard in programming languages for programmable controllers

www.messungautomation.co.in
THE OUTCOME:
The PLC control system allows significant advances and
improvements in the processes of industries, mainly in areas that
demand greater control and environmental air efficiency.
The PLC is used as a reference for PID control. This information is
important to the user to know how is the operation of the equipment
and make necessary changes according to the need of the process.
High reliability for continuous and steady operation with constant air
purity. Plant availability time is better than 90 - 95% always.
The only utilities required is electrical power. Smart control of humidity
ensures energy savings.
