New boosters from Armstrong FT


31 July 2018
Armstrong Fluid Technology has launched its new Design Envelope 6800G boosters which it says are easier to install and commission, save space in the plantroom, and offer energy efficient performance across a wider operating range than ever before.

Bringing together the benefits of Armstrong’s Design Envelope control technology and IE5 rated motors, the new packaged range is said to offer contractors major advantages in installation savings and reduced commissioning time. In addition, the integrated variable speed intelligence embedded in the controller optimises energy efficiency throughout the booster’s lifetime.
The boosters address the water delivery challenges of high-rise buildings by combining Vertical Multi-stage pumps with advanced variable speed controls. Supplied fully-assembled and integrated, Armstrong 6800G packaged booster sets can be configured with 2, 3, 4 or 5 pumps to suit the application. Product selection is simple and quick, with purpose-designed online selection software, along with a Return on Investment calculator tool to help contractors quantify savings for their customers based on actual project data.

Off-site manufacture means that the packaged booster sets are fully tested prior to delivery, with minimal wiring and mounting required on site. Armstrong Design Envelope solutions are sized on the basis of efficiency across a wide range of duty points, protecting against the need for re-selection, and providing energy-efficient performance across a wider range of operating conditions than other models.

Accurate assembly is guaranteed, as the boosters are manufactured by Armstrong’s own engineers, with product-specific fluid dynamics expertise underpinned by ISO quality procedures. Designed using the latest 3D computer modelling, the range typically delivers a space saving of around 25% over competing models.

Embedded control logic ensures optimum efficiency at all times, adjusting pump speed, and staging pumps on and off as needed during periods of high and low demand. Users can also select different operating set-points for different seasons. This optimised control capability, combined with IE5 high-efficiency motors, enables the boosters to deliver energy savings of around 15% compared to alternative models.

Leading BMS communications protocols are supported, including Modbus, BACnet MSTP and BACnet IP.

The package also has its own 107mm colour touchscreen with 128MB flash memory providing a comprehensive range of information, including energy profiling and real-time pump data. If there is a requirement to re-charge the system with water, the automated Softfill feature reduces the risk of hydraulic shock damage and water hammer by controlling the pump speed to ramp up gradually to a fill setpoint.
