Blowdown valves for tandem
or continuous service
Clampseal blowdown service valves
(photo) provide necessary control for
continuous or tandem boiler or turbine
blowdown and bottom blow-off service.
The blowdown valves are available
in sizes ranging from 3/4 to 4 in.,
with butt- or socket-weld and flanged
ends in various materials, with customizations
available. The valves feature
a uniform one-piece gland that eliminates
the potential for stem damage
from gland cocking. With leak-proof
bonnets, the cartridge-style packing
chamber facilitates rapid access to the
valve trim for inspection and maintenance.

Precise temperature regulation
for chromatography columns
The new EchoTherm Model CO50 programmable
chiller/heater (photo) for
high-performance liquid chromatography
(HPLC) columns has a readable
temperature range from 4 to 100°C and
setpoint capability to 0.1°C. The control
software regulates temperatures to
±0.2°C, even at ambient conditions.
The CO50 has an indicator LED that illuminates
when the target temperature
is stable to within ±0.2°C. The CO50
is suitable for chiral and biomedical
chromatography where below-ambient
temperatures help preserve bioactivity.
The CO50 holds columns up to 30
cm long with 1/4- or 3/8-in. diameter in
provided mounting clips. Larger-diameter
columns can be used by removing
the column clips. - Torrey Pines

This software manages
tags for project handover
SmartPlant Master Tag Registry (MTR)
is a software module intended to simplify
how companies manage equipment
and instrumentation tags and
register the information required for
project handover. It is said to be one
of the first commercially available enterprise
products to target the systemic
problems associated with tag
management in the industry. MTR
provides specific functionality to automate
consistent tagging rules among
supported products, and then makes

Extend VFD service life
with these devices
This company's Sine Wave Filter
products (photo) eliminate premature
motor damage from overvoltages,
cable ringing, motor overheating and
eddy-current losses caused by variable
frequency drives (VFDs). Suitable
for motor frequencies up to 600 Hz,
this technology converts the rectangular
pulse-width modulation (PWM)
output voltage of motor drives into
a smooth sine wave with a low residual
ripple. In addition to elongating
the service life of high-speed motors,
the Sine Wave filters can improve
bearing life by eliminating circulating
bearing currents. Typical applications
include pumps, conveyors, compressors,
HVAC applications and motor
drives with multiple motors or long
motor cables. - Schaffner EMC Inc.,

New coagulant blends for
water-treatment applications
Two new coagulants, CDP2727 and
CDP2724, have been introduced to the
KlarAid product line. The custom-designed
blends are based on a high-molecular-weight
organic coagulant and a
high-basicity aluminum coagulant. The
new products have improved capabilities
for reducing the turbidity and total
oxygen content (TOC) in low-turbidity
raw water when compared with predecessor
products, says the company.
CDP2727 is the more concentrated
product, and CDP2724 is a diluted version
that is suitable where low volumes
and dosages are preferred. These
products can be used alone or in conjunction
with anionic flocculants. - GE

tag register generation, management
and monitoring more efficient in large
projects that may include thousands of
individual tags. Traditional methods for
handover involve the manual collection
of key technical data from numerous
sources. MTR automatically collects
and organizes tags as they are created
and used in various work processes
during projects - Intergraph Corp.,
