SIMPLE VALVE TESTING
Fluke’s new handheld 710mA Loop Valve Tester (available from Comtest) simplifies testing with
dedicated tests that perform a quick health check to provide users with good/marginal/bad
results. The device allows technicians to source the 4-20mA signal while it interrogates HART
data to collect critical information about the valve’s position and status, providing quick checks
of control valves while they are in place. With built-in test procedures and an intuitive interface,
the Fluke 710 allows technicians to quickly and easily perform valve tests, while the valve test
quick-check results provide at-a-glance diagnostics to make faster maintenance decisions. Test
results are stored in the memory of the valve tester where it can be uploaded to the included
ValveTrack analysis software.

ALL ROUND ACOUSTIC COMFORT
During the construction of home or an office, General Insulation
Suppliers distributes AeroSound acoustic solutions that feature
appropriate standards of the building, air conditioning, proper
ventilation, and orientation towards cardinal points of the
compass, sun exposure or the distance from noise sources, such
as busy roads.
AeroSound HD is a solid flexible rubber 4.5 – 5kg/m 2 weight and
3mm thickness rendering high performance as a sound barrier, as
the product itself or along with other Aerofoam products. the flexible
and tough structure resist sound waves reducing noise transmission.
Aerosound HD is produced and supplied considering large number of
applications and market requirements.
It is ideal to use in hotels and manufacturing facilities. It can reduce
road noise and noise coming from compressors and generators.
Furthermore, it doesn’t contain fibers, asbestos, heavy metals or
bitumic components.

REFRIGERANTS FIT FOR AC SYSTEMS
In response to a global shift away from R410A and R22, Danfoss has added a complete
portfolio of components to help OEMs develop air conditioning systems with R32.
With its relatively low global warming potential (GWP) at GWP-675, high volumetric
capacity and efficiency, lower purchase price and system charge, R32 has become one of
the most popular alternatives—along with R452B and R454B—to R410A for commercial air
conditioning systems and heat pumps.
In response to high demand—and following the release of the multi-refrigerant
portfolio for R410A/R452B/R454B earlier this year—Danfoss has announced a full range of
components that enable OEMs to design R32 systems up to 700kW/260TR.
Danfoss’s scroll design enables OEMs to take full advantage of R32’s thermodynamic
properties, with +10% volumetric capacity for a same compressor size.
