For 26 years ELOTECH has been developing and producing electronic and software power output components for the PID controller sector. With this experience and potential, ELOTECH now offers its own innovative controls with integrated power controllers and is setting new standards in this product category.

 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. 

Need even more output power? We also offer custom control cabinet solutions. Here, there are practically no limits on the number of zones and the output power level for the overall system. Where the top RT products end at 400V and at 25 A depending on the variant, control cabinets can also be fitted with 1000 A breaking capacity. We will be glad to visit you to discuss special cases individually.  

The performance features of RT products

  • All in one device: Regulator and power controller – the control cabinet is history.
  • Very rapid adjustment without major overshoot
  • Simple, intuitive operation
  • New operating concepts with Webserver and APP
  • Outstanding price - performance ratio

The benefits to you

  • No additional control cabinet construction – all in one system.
  • Precise rapid adjustment increases productivity
  • Fewer operating errors - less need for expensive training on controllers.
  • Easy to integrate into the complete system, more effective remote maintenance and faster support

Implementing requirements optimally and striving for continuous perfection

The increasing complexity of industrial plant and, contrarily, intuitive operation of these systems, is at the heart of our work. The controlled systems are becoming more complex and are posing constantly new challenges for the control. For example, the industrial trace heating area with its sometimes-numerous heating phases, delays and dead times in the controlled system. Rapid heating phases are combined with slow heating phases with different insulation materials.

With this controller generation we are setting new standards. The ideal case is to be able to achieve optimum control results with one button. With automatic self-optimising, the controller analyses the controlled system and adjusts the parameters optimally. There are however many custom applications: compound heating, cascading or time and output-delayed heating phases, e.g., for heating mantles, ensure that the sensitive glass cube is not destroyed by glass stresses. There is a huge range of possible applications. We will also gladly translate your individual requirements into a solution.

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.

PID controllers with power outputs for all sizes

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 32 zones. In addition, two of the 32 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.

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 algorithm is the decisive measure in all things

The new style of operation<br/><br/>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 up to date on what is happening at all times and can intervene as and when necessary.<br/><br/>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.

PID controller with power output in custom format

Example: Multi-zone control for tool heating in a press.

In large industrial plants where high-powered heating is used, contactors are used as power controllers. In this case for example, 6 zones are wired respectively via separately contactors (total: 90 A at 230V / Phase). The complete system is designed for 80KW. The A4000 indicator operates as an additional monitoring system with separate sensors. At the customer's request, we integrated additional protection systems, such as individual fusing of each line. This "power controller" is used in a tool-making press. 

If you need to switch more power than the ELOTECH RT family allows (max. 32A at 400V), we can supply complete control cabinet solutions, all made in-house, including implementation of the electrical design and preparation of the control cabinet documentation. Get in touch. We can find a solution for your problem. 

 

16-zone PID controller cabinet

This solution is equipped with two 8-zone R4000s. The 16 x 25A solid state relays switch each zone up to 3.5 KW. Communication with the outside world takes place via a Profinet interface. Active cooling ensures the right climate. Each zone is also fused with B16A automatic circuit breakers and each controller also has two 50A fuses and a main switch. The planning, construction and testing of the switch cabinet takes place taking into consideration the following regulations: DGUV (BGV A3), VDE 0100 part 540, VDE 0113 (DIN EN 60204-1) and DIN EN 61439-1.
