The move is aimed at boosting energy savings and efficiency in light commercial, residential and industrial applications.

“Design Envelope pumps offer a combination of low installed cost, versatility, energy efficiency and responsive, variable speed operation,” said Wayne Rose, global marketing manager – pumps.
 
Features of the Design Envelope range include sensorless variable speed control, integration of pump and controller and compliance with ASHRAE 90.1 energy efficiency guidelines.
 
“Designers and installers are seeking pumping solutions that offer the lowest installed costs and lowest life cost with industry-leading operating efficiencies across the entire range of duty requirements,” added Mr Rose.
