Armstrong pushes the Envelope
Armstrong Fluid Technology has launched the new Design Envelope 6800G boosters which are easier to install and commission, save space in the plantroom, and offer energy efficient performance across a wider operating range than ever before.
The new Armstrong 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, they 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 to help contractors quantify savings for their customers based on project data.
Off-site manufacture means that the packaged booster sets are fully-tested prior to delivery, for quick, trouble free installation and commissioning, 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.
Embedded control logic ensures optimum efficiency, 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 booster package also has its own 107mm colour touchscreen with 128MB flash memory providing a comprehensive range of information. Complying with industry association codes such as WRAS certification, the Armstrong Design Envelope 6800G also provides peace of mind. And if there is a requirement to re-charge the system with water, the fully-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.
