For 25 years ELOTECH has been developing and producing electronic and software components for the hot runner control sector. Now ELOTECH is using this potential to offer its own innovative controllers and sets new technological standards here.

Made in Germany stands for German engineering and production technology. The RT family offers optimum control characteristics and easy operation with optimum price-performance ratio. The expertise from more than 250,000 industrial temperature control applications have fed into the ELOTECH control algorithm. Continuous software development has enabled ELOTECH to develop this unique algorithm. 

The performance features:

  • Very rapid adjustment without major overshoot
  • Simple, intuitive operation
  • New operating concepts with Webserver and APP
  • Outstanding price - performance ratio

The benefits to you:

  • Shorter machine warm-up time and longer production times – optimised system exploitation
  • With minimum overshoot – considerable reduction of damage to the nozzle and thus less failure times and higher productivity
  •  Fewer operating errors and less use for expensive training
  •  Easy integration, better remote maintenance and faster support

“Implementing requirements optimally and striving for continuous perfection”

The injection moulding sector constantly faces new requirements: Smaller plastic components, new temperature-sensitive materials and faster controlled systems due to smaller nozzles are the current technological requirement pinch pints for control technology. The controlled systems are becoming more complex and are posing constantly new challenges for the control.

The ELOTECH RT controls fulfil precisely these requirements. The innovative PID self-optimisation and constant recalculation of PID parameters in millisecond cycles mean control in a matter of seconds with negligible overshoot. Faster production start-up, less stress on the nozzles and therefore fewer leaks are the direct result. To control very fast nozzles from 20°C to 250°C the ELOTECH software needs just a few seconds at minimal overshoot of a few Kelvin.

Easy to use

Few, clearly defined input options for the user, logical menu structures designed to reflect human thought processes and clear accurate information display with corresponding feedback signals are the requirements for intuitive operation.

The smart user concepts of the RT family enable intuitive use of these controllers. You only need a few minutes to master the well-structured user levels. The user surfaces developed with industrial designers show exactly what you need. Clear and straightforward. Divided into different user levels for users, setters and administrators, each has their own clearly defined control functions.

We call it SMART

Some call it "Industry 4.0“, others "Smart Factory" or "Cyber-Physical-Systems"

We call it SMART - the intelligent networking of hot runner controls with peripheral systems via Profibus, Profinet or OPC UA. Standardised and secure communication from the field device to the Cloud is no longer a vision but, with OPC UA, an achievable reality. The machine-readable semantic description of machine data makes new application cases possible which we will happily implement for you as a customer-specific solution.

We have only one earth – we need to start taking care of it

Faster warm-up but not by too much. This means faster start-up and more economical use of the system. You also save on plastic, reduce wear and tear and increase productivity. Save valuable resources across the board: Energy, plastics, spare parts, time

The innovative compound heating also saves on unnecessary heating energy with intelligent heating and constant output ratio adjustment that simultaneously reduces production costs.

Hot runner controls for every size.

The right system for the right use case. ELOTECH offers the compact hot runner controls in three expansion phases: RT1000, RT4000 and RT7000. All three systems have the same PID-control algorithms. As standard we offer you the RT7000 control with up to 48 zones (from 2021). In addition, two of the 48 zone units are cascadable, so that they can be used, for example, as higher-level controls for compound heating. Need more zones? Here again we offer corresponding custom solutions. As multi-zone controller specialists in the industrial environment we can also implement custom solutions for you. Our largest PID controller application includes several hundred control zones.

The algorithm is the decisive measure in all things

25 years of experience and 250,000 applications in the industrial environment ensure that this algorithm achieves outstanding control results. Constantly striving for continuous improvement means that we now achieve very fast control with minimum overshoot.

The secret: The individual parameters automatically adapt in millisecond cycles to the situation and ensure corresponding control results. The interplay of the individual parameters is also an essential feature in order to optimally control even very high-speed controlled systems, as is the case with very small nozzles or heating rods, for example. Example: From 20°C to 250°C in under 3 seconds with an overshoot of just a few Kelvin. The controlled status is reached in 10 seconds. 

The new style of operation

The integrated Web-Server or the VNC-Viewer APP are respectively available for the RT4000 and RT7000 family for "remote control" functions. Implementation is ridiculously easy. With a nano WLAN router, you can operate systems remotely, integrate them into other systems and carry out control and maintenance without complex wiring. You therefore stay updated about what is happening at all times and can intervene as and when necessary.

Use the ELOTECH hot runner control from your mobile phone, PDA or PC. Start the free APP on your central PC and see everything at a glance via an additional window.
