Bell & Gossett Introduces New ZoneSav™ Controller
|
Morton Grove, IL--Jun 24, 2008
Bell & Gossett has introduced a new Technologic® 5500 ZoneSav™ Controller that is designed
to optimize zone/bridge flow and distribution loop Delta T without sacrificing humidity control and comfort.
|
|
|
The Technologic 5500 ZoneSav™ Controller now makes it possible to "decouple" zones
thermally as well as hydraulically from the chilled or hot water distribution systems.
Ideal for use with chilled water or heating water distribution systems, the controller
is suitable for either two- or three-way control valve applications.
|
By introducing a true tertiary zone valve with a de-coupling bridge, a tertiary zone pump
and a ZoneSav valve controller, the new system allows users to solve several of the
shortcomings of large distribution systems that have grown beyond their original designs,
by eliminating:
· Weak differential pressures in remote branches of the system
· Excessive differential pressures in loads near the main distribution plant
· Wild flow control during outage recovery ZoneSav also provides:
· Diversity control during peak demand periods
· Predictable performance when additional loads are added to the system
|
|
Standard features of the ZoneSav Controller include a wall mounted NEMA 1 enclosure,
temperature inputs/readouts, adjustable PID functions, automatic or manual system
control, system purge, PID auto-tuning functions and energy optimization, as well
as valve limit user-accessible parameters. All ZoneSav Controllers feature
multiple modes of operation, including:
· Temperature/Humidity Optimization
· GPM/BTU Readout
· Flow Limit Control (Zone Flow limiting)
· Differential temperature/temperature optimization
The ZoneSav product offering is complemented with numerous accessories and options
including temperature detectors with 4-20ma output, control valves, actuator and
valve positioner (electric or pneumatic), insertion flow meter with pulse and
4-20ma output, and digital and analog logic input modules for expanded I/O points.
