TECHNOTRANS SOLUTIONS GMBH

The higher process temperatures, the higher the technical requirements for the temperature machine. Decades of experience in construction of temperature machines for heat carrier oil applications up to 400°C makes us the preferred partner of many customers for applications of this kind, particularly in the area of pressing and extrusion. Dimensioning of our teco tt/th series up to 400°C is based on DIN 4754. Design and technical configuration of all temperature controllers are based on the requirements of this norm. Exact film temperature calculation ensures, in combination with flow monitoring, efficient and at the same time reliable operation in all operating conditions. A lockable filter in the circulating medium return line is a standard installation; another installed feature is an expansion vessel with a cold oil container for reliable prevention of damage by oxidation due to oxygen accumulation in the heat carrier.

The patented gwk solution includes cold water temperature controllers that can be operated without glycol in the temperature range between 0 °C and 25 °C. The user can select between two models that are differing in cooling capacity and flow rate. A precise microprocessor control with simultaneous indication of nominal and actual value, the simple one-touch operation, optional interfaces at the front panel and external sensor connection, splash-water proofed electrics and the cabling with CEE-socket ready for connection make the unit ready for immediate use. Leak stop operation, mould draining, acoustic alarm, automatic filling and top up, additional manual filling possibility for conditioned water, strainer in the cooling water connection and parts out of corrosion resistant materials that are in contact with the medium are part of the comprehensive standard equipment.

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.

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.

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.

With the decentralised solution, gwk adds a machine series that offers a high level of flexibility for numerous applications to its portfolio. The customer can individually and precisely set the ideal cooling water temperature for every production machine and for every process in production. Thanks to the direct connection to the consumer, there are no thermal losses, but instead a high flow rate and constant pressure. The weco wd series consists of easy to operate plug&play machines that can easily be installed and commissioned. Three processes can be run with the solution: Free cooling, refrigeration process for low temperatures down to -5°C and temperature control up to 90 °C –everything can be chosen as desired. There is a total of four models with cooling powers between 14 kW and 36 kW (at 15 °C feed flow temperature) and heating powers between 9 kW and 36 kW.

Lime and corrosion are hidden cost factors. Inevitably, these two “enemies of temperature control channels” prolong the cooling time, reduce the process safety and have a negative influence on the parts’ quality. The problem occurs insidiously in each plastic processing company, because lime and corrosion gradually build an insulation layer in the cooling channels and are thus responsible for a deteriorating heat transfer. Often the problem is not recognized until the demanded parts’ quality cannot be achieved any longer or if the complete system breaks down. The effect of cleaning the cooling channels of an injection mould is a reduction of cooling time up to 40 % (in individual cases even more), depending on the amount of deposits. The latest development, easy to use by the processor himself, is moldclean, a compact appliance which cleans polluted cooling channels in injection moulds and heat exchanger systems.

HIGH PERFORMANCE TEMPERATURE CONTROL DEVICE WITH HIGH COOLING CAPACITY, HIGH FLOW RATE AND REDUCED ENERGY CONSUMPTION. 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. In the selection series we used the most frequently selected equipment features and heating performance of the proven premium series advanced. The protemp selection temperature control unit is particularly suitable for the supply of multi-circuit water distributors and is designed for the display of up to 6 external proflow temperature control channels.

Whenever the process requires high temperatures and the advantages of water as heat carrier (best heat conductivity properties, inexpensive, low viscosity) are to be used, this construction series is the best solution. Absolute reliability, high regulating accuracy, easy operation and a favorable price /performance ratio: apart from the versatile performance features a modern temperature controller has to fulfill, these are the key criteria for the temperature controllers teco wh/whx. As one-circuit and multi-circuit units, our modular temperature controllers in the teco whx series cover a wide performance spectrum. Heating capacities of 12 to 600 kW, max. possible cooling capacities up to 1460 kW* and pump flow rates of max. 200 m3/h are impressive basic data of these technically sophisticated temperature controllers for operation with compressed water up to 220 °C.

AIR- AND WATER COOLED COLD WATER UNITS gwk chillers in the sklc series are air-cooled compact cold water units with integrated condenser gwk chillers in the skw series are water-cooled compact cold water units cooled with external cooling water These chillers are equipped with screw condensers; the power regulation of the capacity to be dissipated is continuous. Water-cooled cold water units in the skw series with low coolant content can be operated very efficiently and are preferably used when the available cooling water from gwk cooling towers, gwk free cooler systems or customer-provided supplies has a higher temperature level than required for the production process but is available inexpensively..
