Enersave series - proflow 4-6 ultrasonic

The multiple water quantity control system in modular design that is available in several versions fulfils not less than three requirements at the same time. It combines the advantages of the conventional water distributors, the impulse cooling systems and the continuously operating temperature control units while eliminating the disadvantages of each of these systems. The temperature control system disposes of up to 128 individually adjustable circuits and is suitable for the processing of polyolefins and technical thermoplastic materials. In case of the basic execution (itd B) the requested flow rate is adjusted manually and is then monitored by a flow meter and presented digitally and graphically on the central display of the control unit. In the standard execution (itd R) the water quantity is individually set for each circuit at the central operating unit and - if necessary - is readjusted automatically via a water quantity regulation valve within adjustable limit values.

PROCESS DATA MEASUREMENT AND PROCESS CONTROL ON HIGHEST LEVEL AND NEARLY MAINTENANCE-FREEFollowing the user‘s request for easy maintenance and low susceptibility to slightly soiled water, the proflow mechanical - as a replacement for the current and widely used standard measuring variant with impeller or turbine - now makes mechanical measurement according to the differential pressure principle (without rotating parts) available. The sensors can be visualized via a protemp controller or connected to a PLC. A completely non-contact flow measurement based on the ultrasonic principle is available with the proflow ultrasonic. Robust flow measurement in consumer return line PT 1.000 temperature measurement in consumer return line 6 x 2 consumer channels 3/4“ female screw thread 1 x 2 main connection 1“ female screw thread Available in three temperature variants: operating temperature up to 100°C, up to 160°C and up to 180°C Max. flow rate each channel:: 25 l/min or 50 l/min

The integrat 80 is used for the modular temperature control with water up to 140°C in the basic version with up to six temperature control circuits to be operated completely independently of each other. The basic version can be expanded with extension columns and up to 24 temperature control modules. As an option, the temperature control circuits can be extended with the 4-way distributor vtc with flow and temperature measurement. Thus, a maximum of 96 temperature control circuits can be monitored with the vtc 4-way distribution system. In conjunction with the standard heating control system used as standard, a homogeneous temperature profile on the mould cavity surface is achieved in an extremely energy-efficient manner, as well as with constant cooling by using a motor valve. As an option, the pumps can also be operated with frequency control unit. This improves the procedural results and contributes to energy savings.

Dynamic mould temperature control is a temperature control method that allows temperature variations within the cycle and is also known as “variotherm temperature control”. While this method has been known for almost forty years, it has only undergone a dynamic development in the last few years. This is due to the increasingly exacting quality requirements of consumers (e.g. prevention of visible joint-lines, gloss variations and other surface defects) and the use of plastic materials in new applications. When a temperature control system is selected it is important to mind that it matches exactly with the application and that the economic benefit justifies the technical efforts as well as the energy consumption.
