Mitsuba has developed various options of Manual & Automatic Powder Spray Booth with the choice of recovery type. They are equipped with features of fast color change, highest effficiency and a clean work environment. Powder recovery is the most crucial stage in the complete powder coating process. This should be designed keeping in mind the most crucial features desired eg. If fast color change is desired the type of recovery will be different than when 100% recovery is desired. The type of Powder Recovery to be used depends on the parameters such as the efficiency of the recovered powder required, number of colours to be used, environmental effects, area available at the site, etc. By compromising on one parameter the user may be able to get a very high performance of his desired function. Recovered powder can be reused with fresh powder in an appropriate proportion. The powder is sieved & cleaned with the help of a powder sieve where the dust particles are separated from powder. Mitsuba offers the all types of Powder Recoveries: 1. Powder Coating booth with Cyclone Recovery UNI Series 2. Powder Coating booth with Rotary Cyclone Recovery CAT Series 3. Powder Coating booth with Cartridge Recovery OXYGEN Series Cyclone Recovery UNI Series– Stainless steel cyclone facilitates better color changes. • Lower Initial cost. • Fast colour change. • Available in epoxy coated mild steel, stainless steel and poly Carbonate construction. • Modular construction makes shipping and installation easy. • Can be integrated with powder manager. Rotary Cyclone Recovery – CAT Series New Rotary cyclone booths use rotary vanes in each cyclone there by boosting centrifugal force & providing the extra spin essential resulting in 99% recovery. Reasonably fast color change is achieved because rotary vanes completely eliminate duct work & provide a self cleaning property to the cyclones. However the color change is not as fast as UNI cyclones. Rotary cyclone is wholly integrated top entry system where the “Powder Air” mixture enters a stabilizing chamber and is then equally distributed at an exactly equal pressure and volume in each clone. This special design results in a guaranteed 99% plus powder recovery. All the ductwork is truly eliminated. Since powder enters from the top of every clone through the stabilizing chamber access to clones for cleaning is extremely easy. Access door is provided on the stabilizing chamber to facilitate cleaning of the stabilizing chamber which can have powder deposits – specially if moist powder is used. Rotay wings on top of each clone provides strong centrifugal action to the powder air mixture and therefore very high recovery efficiency. Pressure drop is reduced because of absence of ductwork. The axial entry cyclone with Rotary Vane technology makes this booth most suitable for fast, multi colour powder coating line. Can be used where there is height restriction. Summary of Benefits : • 99% collection efficiency. • Very compact size. Reasonably fast colour change. • Ductless design. • Can be integrated with powder management system. Cartridge Recovery – OXYGEN Series Mitsuba offers the highest power recovery with cartridge recovery system. Summary of Benefits : • 100% power recovery • No need to mix new and old powder. All over sprayed powder can be used. More coating per kilogram of powder • Lower power consumption as no after filter is required • Horizontal flow assures uniform film thickness • Higher life of cartridge filter with unique Rotary wing cleaning mechanism * Depending on the type of powder. *After filter will capture the powder escaping out of the cyclone / Rotary Cyclone and allow only clean air exhaust to atmosphere.
