Auxiliary E-coat Equipment
The Power Supply is an AC/DC converter with adjustable constant voltage capacity of 50-500 volts. Rectifiers delivering DC of less than 10% ripple factor are standard.
The Liquid Chiller supplies cooling medium to the heat exchanger in the e-coating tank in order to control bath temperature. Heat from the circulation pumps, from voltage/current flow, and from parts exiting dry-off, is removed.
Paint Replenishment equipment feeds the electrocoating tanks. If the pigment and resin are furnished separately, the system supplies them, pre-mixed to the specified ratio by a static mixer which is integral to the system.
Ultrafiltration Membranes pass water and dissolved substances and collect dispersed paint resins and pigments. The permeate (or ultrafiltrate) is used to rinse the product as it leaves the electrocoating tank. This rinse recovers un-deposited paint, which cascades back to the tank through counterflow rinsing. Efficient, well-engineered ultrafiltration allows repeated recycling of un-deposited paint, and a resultant material utilization of 99%+.
Material Handling, including carriers and fixtures as well as conveyors and monorails, is the key to overall system efficiency. KOCH designs, manufactures, and installs all forms of conveyance, from traditional monorails to advanced power and free conveyors.
Controls offered by KOCH include simple relays to the most advanced PLCs, as well as specialty devices, such as those for strategic safety lock-out and electronic data interchange.
