We are proud to introduce our new NovoCon® M, L and XL digital actuators. The new actuators, in conjunction with the AB-QM valves, achieve high-precision dynamic hydronic balancing and control for high flow applications.
The NovoCon® M, L and XL are specifically designed to accurately control high flow rates. In specific:

• The NovoCon® M is used for AB-QM NovoCon valves in DN 40-100 suited for flows from 3-59 m3/h, e.g. for air handling units
• The NovoCon® L is used for AB-QM valves in DN 125-150 suited for flows from 36-190 m3/h, e.g. for chillers
• And NovoCon® XL is used for AB-QM valves in DN 200-250 suited for flows from 80-370 m3/h, e.g. for district cooling

Unlike the NovoCon® S, the new NovoCon® M, L and XL don’t use plug & play connectors and cables. Instead the actuators can be daisy-chain wired using standard cables which makes it easier to cover longer distances. The actuators are equipped with 3 resistance inputs to connect e.g. temperature sensors. When such sensors are installed on the supply and return connections, the NovoCon® actuators can be used for advanced control functionalities like Delta T limitation or Return temperature control. With these functionalities the energy efficiency of the AHU or Chiller can be optimized.

Danfoss AB-QM 4.0 Flexo with AB-QM valve is a compact and time saving connection set – designed for creating optimal hydronic balance in cooling and heating applications with variable flow (such as fan coil units (FCU) or chilled beams). Flow is controlled by the AB-QM pressure independent control valve to avoid overflow and reduced efficiency of thermal unit.

The VLT® Advanced Active Filter is easily controlled via the user-friendly LCP, sharing design and programming structure with the VLT® drives series.
Without dismounting existing installation, the VLT® Advanced Active Filters are easily retrofitted to the existing installation, where harmonics are increased because of enlarged employment of non-linear loads such as variable speed drives.
Voltage range : 380 – 480 V AC 50 – 60 Hz
Current range : 190 A, 250 A, 310 A, 400 A. Up to 4 units can be paralleled for higher power
