Features and characteristics

The new evolution G-125/G-200A air driven proportioning unit is of an advanced and compact design. It is specially aimed at the applications of polyurethane foam in place (G-125A), polyurea and polyurethane coatings (G-200A). Its particular configuration facilities easy access to all its components, simplifies the control functions ad significantly reduces the maintenance work.

Primary Heating System

The primary heating system consists of two separate independent block heaters. Each heater incorporates 4 each 1250W (1500W G-200A) heating elements that supply a total power of 5000W (6000W G-200A) with the necessary control and safety features for the accurate and reliable performance of the system. The special design of the heaters allows for a DT of 40ºC and enables it to reach application temperatures of 90ºC in normal environmental temperature conditions.

Hose Heating System

The hose heating system is designed with 3000W isolation transformer that allows the heating of up to 93m. The system incorporates an innovative concept of heated hose in which the copper resistance element is homogenously spread around de hose. This allows accurate and uniform control of the application temperature of the products and avoids the heat concentrations that are produced in traditionally manufactured hoses.

Control Panel

The control panel consists of a touch screen that incorporates specially designed software to facilitate the selection and control of all working parameters in quick and easy manner. A sophisticated alarm system warns the operation of any error in the process to ensure the right application of the products. As an additional feature, a phase connection alarm is incorporated into the design to avoid costly repairs from errors or mistakes when plugging the proportioner into the electrical supply.

Proportioning Pumps

The proportioning pumps are manufactured from high hardness tempered aluminium and a special treatment that offers a low coefficient of friction, a high level of lubrication, and an increased level of wear resistance. The system includes a common guide system that ensures dynamic stability guaranteeing the correct alignment of the pump group and extending the life of the packing seals.
