Water distributor with automatic valves

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.

MULTI-ZONE TEMPERATURE CONTROL- AND MONITORING SYSTEM WITH NON-CONTACT FLOW MEASUREMENT. Due to the design, dimensioning and selection of the used components, enersave temperature control systems are the most efficient systems on the market with the highest flow rates at operating point. By using the frequency inverter, the already high basic efficiency is optimized and the pump characteristic curve will be optimally adapted to the respective operating conditions. The flow measurement of the individual temperature zones is carried out using noncontact measurement technology according to the ultrasonic principle.

Brand-new perspectives and possibilities are offered by the dynamic temperature control with CO2. This new and environmentfriendly procedure really provides a solution for heating and cooling of complex and thinwalled moulded parts. By using gaseous media for heating and cooling processes, soiled cooling channels are now a thing of the past. Basically it is true that gaseous media have the disadvantage to be bad heat carriers. This applies at least to air that is only used for cooling processes under special circumstances. But in contrast, if the opportunities of CO2 are exhausted properly, it offers an interesting alternative to conventional water temperature control.
