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.

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 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
perfectly match your application needs. This enables you to combine the best of two worlds: a well-proven foundation and the 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:
• 230 V +/- 10% full functionality
• 230 V - 20% reduced functionality

Power:
• Power level: 200 - 2400 W
• Specific levels: 200 / 550 / 1100 / 2400 W

Applications
The EC NOVA 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.

• Air-handling units
• Compressors used in heat pumps/air condition units
• Water pumps
• Conveyors
• Refrigeration

To ensure the most energy-efficient and reliable operation, the EC NOVA Drive works perfectly together with different motor types – both permanent magnet (PM) motors (high efficiency), standard asynchronous induction motors (high start torque), and BLDC motors (cost efficiency).

Features and benefits

• Increase operation options as the product is water splash protected (rated IP54). The IP rating can be adjusted to match your needs with a rating up to IP67

• Allow for operation in still-air environments, e.g. a ventilation system, with passive and active cooling

• Ensure reliable and cost-effective operation in demanding environments, e.g. compressors, thanks to its robustness

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

• Increase usability thanks to the compact design that fits 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

Let’s build your next star EC drive

• Should your product be water-cooled or air-cooled? NOVA can do both.

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

• Should the product be mounted with screws? We adapt the mechanical adjustments to meet your specific needs.

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

• Do you plan to use the EC drives in wet environments? No problem. NOVA can be designed according to different IP ratings up to 67.

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.

• 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.
