Soluzioni IT VERTICAL POWDER COATING LINES SAT S.p.A. is a company projecting, producing, installing and providing technical assistance as far as regards lines able to carry out surface finishings and packaging solutions on aluminium extrusions. SAT S.p.A. can supply vertical powder coating plants, anodizing lines, sandblasting machines and packaging systems for aluminium profiles, proposing multiple configurations and advanced technical solutions. SAT S.p.A. is as a company strongly oriented to innovation, in fact, thanks to a skilful and The first vertical powder coating plants were introduced in Europe by Trevisan at the beginning of the ’80 reprising the vertical liquid plants concept already in operation in the U.S.A. to coat aluminium profiles on a large scale. The increasing demand for aluminium in the building sector, the need to optimize running costs and at the same time the productivity of the lines (a vertical line means less operators and more output if compared to an horizontal plant), allowed a large spread of this kind of plants all over the world. experienced staff as far as In these last thirty years, in the most demanding powder coating markets in terms of industrial performances, a great change as far as concerns the aluminium coated profiles market has occurred: the range of colours and finishings required has enlarged and the big white lots demand has been replaced by a small polychrome groups of profiles request. We have to point out, all over these years, Trevisan has always interpreted these signs of the market extremely fast. Very often the innovations introduced by the Trevisan brand have also anticipated some circumstances job coaters would have had to run up against in a following moment. efficient as possible a production concerns industrial plants for aluminium, we project and realize applications capable to produce relevant changes in traditional lines running models. Our philosophy aims to convert the market's needs and impulses into instruments to make as cycle. Our constant research allows us to project and realize plants with innovative elements in order to grant to our customers extremely high performances. SAT S.p.A. is proceeding with the same philosophy: innovations suitable for the scenario prefigured by the signs of the market. This means plants with a relevant technological content. Thanks to a skilful and experienced staff as far as concerns industrial lines for aluminium, SAT S.p.A. has already developed solutions capable to create substantial benefits in terms of running costs and plant automation level. Among them we can include: Pre-treatment Tunnel with PVC body Energy Saving Drying Oven Curing Oven with “Revolving Doors” constantly closed (SAT Patent pending). SAT S.p.A. Via A.

VERTICAL POWDER COATING LINES 1) PRE-TREATMENT TUNNEL CASCADE The pre-treatment tunnel is the part of the plant that treats the profiles' surfaces to prepare them for subsequent powder coating process. ADVANTAGES SAT S.p.A., for the pre-treatment tunnels, makes use of the "cascade" technology, which gradually replaced the "spray" system since it grants the following advantages: TECHNOLOG Y COMPAR ED W ITH NOZZ LE S LESS MAINTEINANCE LESS ELECTRICAL POWER 1) Less maintenance required (no nozzles to clean periodically) REQUIRED IMPROVED CHEMICAL 2) A more strong chemical attack (the chemical solution...

VERTICAL POWDER COATING LINES 2) FAST CLEANING BOOTH FAST C LEAN ING This booth has been developed in compliance with the need of the most demanding powder coating markets in terms of industrial performances, healthy working environment, ergonomic use, cost effectiveness and quality of the final product. The entire powder coating application system has been re-design with the aim to get a colour change time in less than 5 minutes. The booth foresees the recovery circuit for the over-spray and is provided with electrostatic powder coating deposition equipment. BOOTH ADVANTAGES COLOUR CHANGE TIME:...

VERTICAL POWDER COATING LINES 2) QUALITY a) With reference to previous generation of booth models, thanks to an accurate study of the air extraction system and of the profiles path in the booth the powder deposition efficiency has been improved that is an increase of the share of powder that applies directly on the profiles. With the same number of guns it is possible to increase the conveyor speed even with profiles difficult to be painted. b) Quality of the coating improvement both in terms of uniformity of the layer thickness and in terms of powder penetration: thanks to the cloud of powder...

VERTICAL POWDER COATING LINES 3) OVENS ENERG Y SAV ING SAT S.p.A. TAKES GREAT The drying oven evaporates the water film left on the profiles' surfaces after the chemical treatment in the tunnel. The operation must be carried out before applying powder. The polymerization oven is where the powder polymerization takes place at a temperature generally between 170 and 200° C. CARE OF ENERGY CONSUMPTION WITH RELEVANT REDUCTIONS ACHIEVED THANKS TO: CASCADE SYSTEM ON PRE-TREATMENT TUNNEL Drying Oven ENERGY SAVING DRYING As far as regards the drying oven, SAT S.p.A. can propose two versions: OVEN 1)...

VERTICAL POWDER COATING LINES 2) The "Energy saving" drying oven: drying chamber with straight path and environment heating carried out by means of hot water battery . The advantages of this configuration are: a) Reduction in thermal energy consumption (no burner installed but hot water battery heated by the water of the burner closed circuit. The energy required by the drying oven is partially provided by the curing oven fumes heating recovery).
