NHP has introduced the NHP MODdrive HVAC ECO range of variable speed drives, designed specifically for HVAC applications.
According to the company, the NHP MODdrive HVAC ECO has a user-friendly design and is available in IP66 to 11kW and IP55 up to 45kW. A large OLED display is included as standard, which allows a fuller viewing angle, high contrast, quick navigation, and faster setup.
It is a dedicated ‘low harmonics’ HVAC variable speed drive that uses the latest technology to minimise disruption (harmonics) of the incoming mains power supply typically created by non-linear loads such as standard variable speed drives.
The variable speed drive reduces harmonic current distortion to below 30% iTHD (Total Harmonic Distortion), whilst also increasing efficiency by reducing the input current levels, leading to reduced lifetime costs. In addition, it incorporates a film capacitor design which offers increased efficiency and longer shelf-life compared with standard variable speed drives.
It includes fire mode operation, which is particularly useful in smoke extraction systems and stairwell pressurisation applications.
