Dip Pretreatment Plants are offered depending on the production volume and article configuration. Our pretreatment systems have special provisions in their design to get the best out of both-spray as well as dip type of pre-treatment systems.
The dip pretreatment systems have been designed to keep the cost low. The heating systems and the oil skimmer help further this objective. Dip type pretreatment plants with hoist are for manual handling. In conveyorised dip pretreatment plants, articles / components are hanged on a conveyor and are dipped into the tanks. In this operation, the articles / components travel through a sorter of tanks, thanks to the programmable conveyor line. Transpoterised dip pretreatment systems use transporters for automatic material handling using PLC control. To ensure quality, we offer the following features as standard features of our systems:
Oil skimmer - To maintain minimum oil contamination level in the degrease bath.
Sludge removal system - To maintain low sludge level in the phosphating bath.
· Various Heating systems
· Thermic Fluid
· Hot water
· Direct immersion heater
· Direct immersion heater
Diesel / gas burners
Spray Pretreatment -This system for online cleaning of components consists of a tunnel mounted on tanks, piping, pump and nozzles etc. The design is based on conveyor speed, article profile & pretreatment timing. The spray tunnel is designed on a completely weld-less system. This eliminates chances of leakage. Special arrangements ensure leakages locking between the zones. The tank design also eliminates leakage and all sprayed chemicals fall back into the tanks.
The heating system is designed to give the best heat transfer and consume minimum of the tank volume. The oil skimmer is incorporated as a standard part of every system to keep the cost of refilling low by getting the most out of the chemicals.
Shivaco Hot Water Generator is modern and fuel efficient heating system provided for chemical heating in pre treatment plants. The heat is being transferred with the help of coils or PHE. The Hot Water Generators are provided either with HSD Fired or Gas fired burners.Air Agitation System
