NEW PRODUCTS TO POWER YOUR BUSINESS
Spectrophotometer with Radio Frequency Identification
Hach Co. unveiled its DR 3900 spectrophotometer featuring stateof-the-art
radio frequency identification (RFID) technology. Hach,
which describes the device as being " similar to a GPS telling you
when to turn, " also says that the DR 3900 requires less training
and increases confidence in the test results. This helps water and
wastewater facilities prevent measurement errors. The DR 3900
further simplifies water analysis by walking users through testing
procedures to ensure consistently accurate results regardless of
the user's knowledge. The device allows for hands-free calibration
updates and enables tracking of samples. It connects easily with any
computer or water management system through one LAN and three
USB ports. (www.hach.com/spectrophotometer)
New Winding Resistance Meter
The Tettex 2293 from Swiss firm Haefely Test AG
is the result of extensive research and years of
experience testing transformers. A simple one-timeconnection
system, together with the simultaneous
winding magnetization method (SWM), drastically
reduces measuring time. The SWM guarantees fast
and reliable measurements even on large power
transformers with delta windings on the low-voltage
side, where stable measurements can seldom
be reached using traditional winding resistance
measurement instruments, the company says.
In addition, the new demagnetization function
eliminates the magnetic remanence in the core after
the application of a DC voltage. A full graphical
interface with a 7-inch touch screen guides the
operator through the test procedure. The unit
visualizes each test cycle and displays the results
graphically or in list format. (www.haefely.com)
Self-Recuperative Burner
Eclipse Inc. introduced the TJSR v5 self-recuperative burner
for direct-fired furnace heating applications. The advanced
burner design combines a high-velocity flame with fuelsaving
recuperation. A space-saving integral eductor pulls
the furnace exhaust through an internal ceramic recuperator.
The recuperator preheats the incoming combustion air to very
high levels, which improves furnace operating efficiency to
reduce fuel usage by as much as 50% over typical ambient air
burners. The TJSR v5 design eliminates the need for the hot air
ductwork required by external recuperators, providing savings
in hardware and installation. The internally insulated heat
exchanger section and exhaust housing hold heat
in the recuperative section, adding to the heat
recovery efficiency. This also keeps external
temperatures very low, providing better operator
comfort and reduced thermal wear on associated
equipment outside the furnace shell. The
integrated gas and air orifices simplify burner
piping, set-up, and adjustment. The TJSR V5
can be fired on natural gas, propane, or butane
and is available in three sizes, with a maximum
capacity ranging from 200,000 to 600,000 Btu/
hr (60 to 175 kW). (www.eclipsenet.com)
