Electronic Variable Ratio Pour/Spray Equipment

Electronic Variable Ratio Pour/Spray Equipment

Simplicity of design is the key to this machines success in local and international markets. Featuring postive displacement, low pressure pumps and driven by variable speed electric motors fitted with VFD drives gives quiet, trouble free, long life operation.

Low Pressure PU Unit Features

The P.U. Elastomer pour/spray applicator has been designed to work on site. For this reason, it is mounted on a mobile trolley, though it can be bench mounted or have a different configuration if required. Urethane elastomer coatings are unique because they can be sprayed onto most surfaces as a continuous protective lining.

Low Pressure Spray

The use of low pressure spray (less than 300psi) enables this unit to be built simply and at a lower cost than other types of spray equipment.

Mixing

Mixing of the two components prior to spraying is achieved by static spiral mixers and a unique interaction air nozzle. Pouring is mixed by static mixers.

Economic

Low pressure spray results in lower operating costs, much lower maintenance costs and does not require heating when used in a suitable ambient temperature.

Low Pressure P.U.

Elastomer Features Pour operation mixing by static spiral mixers. Spraying by static spiral mixer and air interaction nozzle. Heating is not required with low pressure operation at suitable ambient temperatures unless specified by the PU manufacturer.

Specifications:
Pumps: Two positive displacement, low pressure pumps, variable speed electric motors with two VFD drive controllers. Current required 240vACx50 cycles. Other current requirements optional.
Spray/Pour Guns: Gun has simple two ball valve operation using a manual trigger lever to give a stay-on effect. Rugged all metal mixing tube and S/S nozzle have a long life when solvent flushed. Air nozzle has adjustable controller.
Variable Speed Motors: Operating requirements of the variable speed motors is 240 volts AC x50 cycles and air consumption for the flush, solvent tank and air nozzle is 8 cfm. The spraying air consumption is 12 cfm.
Mixing Method: Mixing method for PU elastomer spray is static spiral mixers and air interaction nozzle.
Cleaning: Cleaning of the gun is by air purge and solvent flush. Method is air purge then solvent flush then air purge again leaving the gun ready for shutdown.
