Bell & Gossett Updates TECHNOLOGIC VFD Series

Bell & Gossett HVAC Pump Controller/VFD Offers Faster Setup

Xylem Inc. and its Bell & Gossett (B&G) brand have released the latest generation of their intelligent pump controller/variable frequency drive (VFD). The updated TECHNOLOGIC VFD series combines two advanced controller functions — the Start-Up Genie and an electronically controlled bypass — engineered to reduce on-site setup and configuration time across a range of hydronic HVAC system applications.

“The demand to reduce operating costs and optimize building systems is higher than ever. This bundled offering of B&G hydraulics and TECHNOLOGIC controls ensures a single point of contact and ease of service — a critical factor in pump specification,” said Kyle Schoenheit, global product manager, Xylem. “B&G continues to offer solutions that address our customers’ feedback and meet the needs of commercial building owners.”

The TECHNOLOGIC drive’s proprietary Start-Up Genie guides users and installers through quick commissioning, with its 10 preconfigured applications, preset pump protections, and input/output options. For more straightforward hydraulic applications, a built-in Auto set mode is available that remembers previously set parameters, enabling users to quickly make adjustments without inputting measurements. Set-up time is about 15 minutes, compared to more than 45 minutes for most other products available.

For applications with varying flow ranges, the TECHNOLOGIC has the ability to alter hydraulic performance to maintain constant system pressure. The drive provides constant speed lag control and the ability to control one variable speed pump with up to two fixed speed lag pumps triggered by relay. This duplex configuration provides precise application management. It can support large hydraulic ranges while optimizing system uptime for the end-user.

The TECHNOLOGIC’s bypass option with electronic control ensures uninterruptible operation of the HVAC system by keeping the rotating equipment running, even if the drive is taken out of the loop. Advanced system control features include: automatic bypass; common start/stop in drive or bypass modes; and advanced firefighter’s override.

The TECHNOLOGIC is compatible with any system and a variety of products, including B&G’s Series e-80 vertical inline centrifugal pumps available with Integrated Technologic Sensorless Control VFDs, eliminating the cost and time of using wired transducers to better match system demands.
