Features and characteristics
The Evolution G-50H hydraulically driven proportioning unit has been developed to fulfil the needs of customers who work on big projects where high outputs, constant pressures and temperatures are required to maintain high productivity levels on polyurethane foam, polyurea and coatings applications.
Its open design allows easy access to all its components simplifying control functions and reducing maintenance time.
Primary heating system
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.
Hose heating system
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.
Monobloc proportioning pumps
New Monobloc Pumps with Anti-Leak System (International Patent pending). 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.
