Power Engineering and Inverter Solutions, also for Compressors

We develop and produce a wide range of solutions for regulation of several different types of motors, heating elements and heat sources. In addition to the traditional systems such as triac-regulators and potentiometers our team of engineers have developed our own range of both 1-phased and 3-phased frequency inverters for power systems for regular electro motors and compressor motors in e.g. heat pumps etc. Our approach ensures stable compressor operating conditions, especially when variable speed control is necessary to match changing heating and cooling needs across different applications.

Danish Development

All our frequency inverters are developed by our team of electro engineers in Denmark and are afterwards produced in our Danish factory or in one of our European subcontractors’ factories. This development setup allows us to refine inverter technology continuously, ensuring high energy efficiency where precise adjustment of compressor speed becomes crucial.

Standard Solutions

Our development team has a long and broad experience with electrical engineering for regulation of electro motors. They carefully consider the power systems engineering to obtain the best possible efficiency with the lowest possible energy loss. By working with models ranging across a wide range of motor sizes, we can better support systems that must react dynamically to heating and cooling demands and requirements throughout the operating cycle.

Electro Motors and Ventilators

In our online catalogue there is a range of frequency inverters for smaller ventilators and motors (370W, 750W and 1,5KW). These inverters are all part of the model series E 1045 and are controlled either by ModBus interface, 0-10V signal or potentiometer. They are supplied in a sturdy metal enclosure with cooling ribs. If mounted correctly they do not need any active cooling.

Compressors

We have 2 model ranges in our standard solution of frequency inverters for compressors. These standard models are ready to be used of shelf for a range of compressor models as they are already tuned for the motors in these models. Because compressor motors respond differently at low and high demand, our inverters ensure seamless adjustment of compressor speed to match real-time heating and cooling needs without unnecessary energy consumption.

However, you may often have specific requirements to the design of the inverter or the cold plate / cooling ribs, or you may be using a special compressor. Therefore, many of our customers have one of our standard models adapted or have their entirely own inverter engineered to fit their specific project. Tailoring these systems gives customers greater control over performance, especially where inverter technology must interact closely with all system architectures.

The current range of standard frequency inverters for compressors consist of the model series 1145 and 1002, both with ModBus interface and the possibility of 0-10V signal input. These configurations help maintain optimal heating and cooling capacity while ensuring the system can respond effectively to both high and low heating and cooling demand scenarios.

Model Serie 1145

Frequency inverter series 1145 is available for compressor motors up to 2,0KW and 3,0KW. They are supplied in a sturdy metal enclosure with cooling ribs, either placed crosswise or lengthwise the inverter. This provides more flexible mounting options and if mounted correctly passive cooling will be sufficient. Motor profile is easily selected by setting the dipswitches on the inverter. For installations demanding higher heating and cooling capacity, the 1145’s ability to support variable speed operation ensures improved energy efficiency.

The 1145 models are controlled via ModBus interface. As an additional purchase you can buy an add-on pcb for the inverter, which makes it possible to use 0-10V control signal. This gives system designers improved freedom when balancing compressor operating with heating and cooling demand curves.

Custom Solutions

If the standard solutions do not fit your requirements, just contact our sales team. You can then in cooperation with our engineers find the right power solution and placement to obtain the best efficiency and performance conditions. Our experience can help your project to obtain the optimal solution. This also applies to advanced heat pump applications where custom heating and cooling requirements demand flexible inverter technology that works across a wide range of compressor motors.

Are you using A3 refrigerant such as propane, R290 in your solution, it is not a problem. Even with alternative refrigerants, the inverter system can maintain stable compressor operation points and secure optimal energy efficiency across varying heating and cooling demands.

We adapt and optimize your power system to fit exactly your solution. This includes ensuring that heating and cooling capacity precisely meet system’s needs by variable speed regulation.

Besides adapting our standard inverter series 1045 and 1145 we have also developed 1-phased and 3-phased inverter platforms which we can adapt to perfectly fit your tasks. Most times we can then obtain a higher efficiency for exactly your product and you get a uniquely adapted inverter which are solely produced for your use. These platforms help ensure that compressor speed is matched intelligently to both low and peak heating and cooling requirements, resulting in stable operation and improved overall system performance.
