The EC PURE Drives are actively cooled compact and modular EC drives that can be customized to meet your specific application needs. Thanks to the modularity, you can apply filters and power factor correction (PFC) if, and where, you need it.

What makes the EC PURE Drives family special, is its customization. Building on a platform of high-quality standard features, e.g. compliance with railway standards regarding vibrations, we can tweak the product in a number of ways to perfectly match your application needs. This enables you to combine the best of two worlds: a well-proven foundation and the design-freedom to create a unique product.

The solution is plug & play. This allows you to get going without wasting precious time reading a never-ending manual.

Supply voltages and power range

Voltage:
• Single phase: 208 - 230 Vrms 50/60 Hz
• Three phase: 380 - 400 Vrms 50/60 Hz

Power:
• Single phase: 2.2 - 2.9 - 4.4 - 8 kW
• Three phase: 5.5- 7.5 kW

Applications

The EC PURE Drive is suitable for various different applications. To help give you an idea of the product in use, we have listed the most popular applications below.

• Heat pump compressors
• Water pumps
• Conveyors

To ensure the most energy-efficient and reliable operation, the EC PURE family is able to drive different motor types – both permanent-magnet motors (PM motors) and standard non-synchronous induction motors, using sensorless field-oriented control and V/f, respectively.

Features and benefits

• Ensure reliable and efficient operation in different applications thanks to the robustness of the motor-control algorithm

• Improve installation time and operation with a plug-&-play product designed specifically to fit your application needs

• Ideal for mounting inside the application with a an IP20 rating as standard

• Improve design-freedom with the modular and compact design allowing you to fit the EC drives into small systems

• Strengthen your footprint. The products are small in size, which not only means they are easy to fit into small systems – it also means we can reduce cost on transportation and material consumption to improve your environmental impact

• All PURE drives are 3rd party approved for use in heat pumps and chillers using R290 as refrigerant.
  Other refrigerants can be used provided the Auto Ignition Temperature is higher than +470°C.

Let’s build the EC drives you dream about

• PURE is actively cooled, and you can choose between water-cooling or aircooling.
  PURE can do both.

• Do you prefer an analog or digital signal? Again, we can do either.

• Should the product be mounted with screws? Or maybe you want easy mounting with a DIN rail? We adapt the mechanical adjustments to meet your needs.

• Looks do matter – even when it comes to EC drives. Therefore, we will design PURE to match your corporate identity with colors, labels etc.

• Do you plan to use the EC drives in explosive environments? No problem. The product comes in two versions: a propane version and a standard version.

SureStart® - three phase

The three phase soft starter is designed to significantly reduce start-up current and noise.

SureStart® - RV

The single phase soft starter provides a dramatic reduction in start-up current, typically up to 70%, but still provides enough start-up torque for compressors and motors.

The EC NOVA Drive is a compact EC drive that can be customized to meet your specific application needs. The product can be both actively and passively cooled and offers an IP54 rating as standard, with the flexibility to adjust it to your needs, which makes it the optimum solution in difficult environments.

With NOVA, you have the chance to customize the product. Building on a foundation of high-quality standard features, we can tweak the product in a number of ways to

Sometimes standard just isn’t good enough. We develop and manufacture electronic controls at our own production sites in Denmark and Poland for a variety of HVAC and industrial applications.

With more than 30 years of experience, we customize the products for the individual customer based on existing building blocks. This means that we are not designing
from scratch but upon a foundation of reliable and tested technology.

In combination with our controls and expert knowledge of applications, we can offer a complete package of sensors and transmitters, which makes us a total supplier of
controls and solutions.

The electronic contactors are designed to expand the switching capacity and lifetime of your heating elements, both resistance and induction. All our electronic contactors use LTE technology (Low Thermal Expansion).

With the F-gas regulation coming into force in January 2027, switching of heating elements will also require the switching device to be a non-potential ignition source if flammable refrigerant is used.

Eltwin have now updated selected IC-Contactor models to be ready for R290 (propane). Our IC-Contactors can also be used with other refrigerants e.g., R32 or R454b.
