HUMIDIFICATION INSPRAY BOOTHS, COATING& SURFACE FINISHING
Humidification and Evaporative Cooling
Condair humidifiers are used in spraybooths, coating and surface finishingfacilities around the world to maintainthe optimum humidity and maximiseproduction efficiency.
Some of the world’s leadingmanufacturers, spray booth and airhandling units companies put theirtrust in Condair humidificationsystems to help them achieve theirproduction objectives.
TRUSTED TECHNOLOGY
Condair has manufacturing facilities inAsia, Europe and North America as wellas sales operations in 15 countries anddistributors in over 40 more.
The company has been serving theglobal spray booth and surfacefinishing industry for more than 60years and is highly experienced inworking with many different climates,
painting and coating processes, and alltypes of manufacturing facility.
Humidifier systems are designed foreach individual application byhumidification experts to create theoptimal production environment. Ifrequired, Condair’s regional R&Ddepartments can work with a client’sproduction team to deliver innovative
solutions for specialist painting,coating or surface finishing processes.
Condair’s expert humidifierengineering teams can provideinstallation, commissioning andmaintenance support to ensureimproved production efficienciescontinue to return on the initialinvestment for years to come.

IMPROVED PRODUCTION EFFICIENCYCorrect humidification and humidity control will improve productivity throughmany paint spray, coating and surface finishing processes.
Paint spray boothsRelative humidity levels of between 65-75% are maintained in spray booths toprevent aerosol evaporation andpigment agglomeration, and promoteconsistent deposition rates. Bystopping the evaporation of theaqueous-based paint aerosol, the paintmeets the target surface as themanufacturer intended, improvingfinish and lowering paint costs.
The introduction of precipitated dustfrom evaporated paint is alsoprevented, further improving thequality of the booth’s atmosphere andultimately the surface finish.
Electrostatic painting & powder coatingA relative humidity of between 40-65%RH is typically maintained inelectrostatic paint and powder coatingareas. If the humidity is too high, theeffects of the electrostatic charge aredisrupted, coat adhesion is affectedand higher flow rates required for thesame finish. If the humidity is too low,
the charging characteristics of thecorona are affected so the powderdoesn’t become properly charged,effecting transfer efficiency.
Dipping and electroplatingIf the air is too dry around multi-stagetreatment processes, there is a risk thatthe job can prematurely dry betweentanks. This can lead to staining andaffect the finish from subsequentprocess tanks. Needing to strip andrework materials is time consumingand costly. A humidity of 50-60%RHprevents rapid surface drying andavoids this loss of productivity.
Validation testingProtective finishes are often subject totesting to check manufacturers’ claimsin relation to international standards orperformance and corrosion resistance.It is vital humidification systemssupplying test chambers performcorrectly or the atmosphere can falloutside the specified conditions,resulting in test results being void anda potential restart required.

Commonly, temperature and relativehumidity control will be provided by anair handling system fitted with spray orevaporative humidifiers, deliveringconditioned air directly to one or morespray booths. This might be supplied bythe booth manufacturer or designedseparately and supplied by an airhandling unit (AHU) manufacturer.
For individual spray booths, anassociated AHU may be incorporated ora positive pressure containment roomis built around the booth, conditionedto provide the appropriatetemperature, humidity and airfiltration.
Condair has a comprehensive range ofhumidifiers and associated water
treatment systems to suit any spraybooth, coating or surface finishingapplication. This specialist range iscombined with extensive expertise,working with manufacturers, spraybooth and AHU companies, ensuringCondair always recommends andsupplies the most appropriate solutionfor a spray booth, coating or surfacefinishing project.
