Powder Coating Equipment : Electrostatic Powder Coating Equipments - Corona

Electrostatic Powder Coating Equipments

The Corona-CF is an external Voltage Generation Units. The 220 Volts AC power supply is stepped down to 27V AC. The DC power is then generated from 27 V AC by a rectifying circuit. This DC power is then used to develop oscillations of high frequency, which is then fed to cascade to generate 85 to 90 KV. This is further fed to Gun barrel through High Voltage cable.

At the Gun Tip, electric power is fed to the gun electrode where a Corona is formed & powder is charged to fullest extent.

This is a constant power unit, which ensures voltage & current ratio to ensure proper charging of powder with good coverage & wrap around at different distances from gun tip & the job to be coated. Which results in highest first pass efficiency for better coverage.

The Gun barrel has a unique Vortex Nozzle, which evenly atomizes powder at the tip of the gun to generate a powder cloud. The design ensures straight powder path to ensure flawless powder flow. A variety of powder flow patterns are possible due to special vortex type nozzle design without changing nozzles.

The Corona-CF is a typical electro-pneumatic design with two stages, which can be used depending on the job profile. Pneumatic Trigger, valves & circuit which is used to automate KV & powder flow adjustment for second stage. At second stage change in the KV, reduces powder flow pattern. The difference in charge tackles the faraday cage effect & stops repelling of powder which is an advantage when painting corners & intricate shapes.

The Current & Voltage Limiting feature is achieved through a HV resistor is Gun barrel which ensures operator safety. The Corona-CF also has a unique feature of pinch valve in pump suction which avoids powder spitting.
