DEHUMIDIFIER MACHINE AUTOMATION WITH MESSUNG'S NX-ERA XPRESS
A dehumidifier is a machine that removes excess moisture from the air. An
industrial dehumidifier is built to be transported and used in several hard-wearing locations.
Commercial and industrial dehumidifiers will reduce mold, condensation dripping from pipes or windows, and eliminate musty smells.
APPLICATIONS WHERE DEHUMIDIFIER MACHINESARE USED:
Moisture control is a great concern in the pharmaceutical industry 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.
Dehumidifier machinesallow 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 dryair.
Use of dehumidifiers is able to 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 simply mastering the relative humidity of the air around us.

Messung engineers studied the machine and its requirements, and came up with a solution consisting of
· NX-ERA XPRESS XP325 PLC controller
The dehumidifier control system based on a PLC, which comprises a programmable logic controller, a transmitter, a signal input part, a contactor, anHMI and 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.
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.
The dehumidifier control system which has the advantages of low cost, convenient use, flexible programming, high reliability, strong anti-interference performance, powerful Human-machine interface functions as well as powerful communication functions is easy to integrate in an on-site bus control system as an intelligent node.

BENEFITS FOR THE CUSTOMER
Programming and configuration environment based on IEC 61131-3 standard: the global standard in programming languages for programmable controllers
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.
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. Air conditioning systems do reduce humidity through their action of absorbing moisture onto the evaporator coils.
Ø 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.
Ø Industrial Automation of Air quality has evolved and provided an increasing number of techniques to control temperature, humidity and removal of polluting waste industrial environments.
Ø 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.
Ø High reliability: Very reliable for continuous and steady operation with constant air purity. Plant availability time is better than 90 - 95% always.
Ø The only utilities required iselectrical power. Smart control of humidity ensures energy savings.
