The new evolution G-250H hydraulically driven proportioning unit has been designed and manufactured to fulfil the most demanding requirements of industrial foam in place applications of two component systems requiring high dosing precision to assure the best mixing quality of the chemical components. Its particular configuration facilitates easy access to all its components, simplifies the control functions and significantly reduces maintenance time.
The primary heating system consists of two separate hydraulically and electrically independent block heaters. Each heater incorporates 6 each 1500W heating elements that supply a total power of 9000W 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 50ºC and enables it to reach application temperatures of 90ºC in normal environmental temperature conditions.
The hose heating system is designed with 4000W 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.
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.
A double acting hydraulic cylinder drives two directly opposed chemical proportioning pumps. This design eliminates asymmetrical loads and assures prolonged life of the pump packing seals as well as assures a constant stabilised pressure in order to achieve perfect mixing of the chemical components. Several pump sizes are available to obtain different volumetric ratios.
