Relative humidity is one of the fundamental ambient parameters used to define the normal operating conditions of a cleanroom, and often the limits in tolerance are very restricted
Precise control of relative humidity is required influences the main factors that affect the performance of cleanrooms:
Psychrocontrols has been designing and manufacturing electronic control systems for air-conditioning and humidity control applications.
This specialization, together with the extensive experience acquired, makes PSYCHROCONTROLS the ideal partner for high-tech and industries, Laboratories, Hospitals and warehouse’s where reliability and precision humidity control are essential.
Air handling unit applications feature a very wide variety of system types, with differing degrees of specificity.
For cleanrooms too,PSYCHROCONTROLS can supplysolutions for all installations, whatever their complexity: modular controller up to compete system supervision solutions to ensure reliability, precision and maximum energy saving.
Electrostatic Discharges
To limit electrostatic discharges that are harmful to electronic components, relative humidity should be kept above 30%.
Chemical Reactions
Close humidity control means greater control over processes. The speed of many chemical reactions, including the corrosion processes, depends on the relative humidity.
Bacteria Containments
Controlling and keeping relative humidity between 40% and 60 % minimizes the proliferation of bacteria and other biological contaminants ( viruses, fungi, mould, mites).
PSYCHROCONTROLS is Supplying most suitable type of Temperature and humidity controllers for the installation, together with an optimum control system to optimize energy costs. Intelligent
Intelligent control system will collect the inputs from various locations and asses the best possible conditions based on the set points with respective to the available input of chilled water, hot water and heat exchange capacity of the AHU Controller shall indicate the possible set points of temperature and RH with respective to the inputs According
According to the possible condition’s controller will auto tune the temperature and RH with pression level without any deviation as it is mentioned During the optimization the first preference is for the temperature optimization Then the RH will be auto tuned to best possible level
1.If cooling coil is not performing well, then the controller will indicate the same and auto tune to give the priority to set temperature
2. If the chilled water is supplying at higher temperature, and RH has been set at low level, then the controller will indicate the possible RH and it will auto tune to the best possible set point for the RH at given set temperature
Semiconductors
Extremely precise control limits are required when processing semiconductors,for example, the viscosity of photoresist is very sensitive to relative humidity
Capillary forces
Capillary forces can affect the precision and speed of processes In particular, when relative humidity is high, these forces increase the adhesion of water particles to surfaces
Personal comfort
Relative humidity between 40% and 60% represents the personal comfort zone . Higher humidity causes a feeling of discomfort, while lower humidity causes inflammation of the mucous and chapped skin.
