WORLD’S SMALLEST EEV
Danfoss has unveiled what is believed to be the world’s
smallest electronic expansion valve (EEV) for small A/C
and CRAC units.
For comfort applications, the ETS 5M ensures low
acoustic level, and offers full performance bi-flow
capability – enabling quiet, precise performance for both
cooling and heating.
In addition, the ETS 5M is ideal for high evaporating
temperature computer room air conditioners (CRAC)
with direct expansion. Its precise flow control and
best-in-class protection against moisture and internal
leakage improves system reliability in data centres
where constant temperatures need to be maintained
around the clock. The new valves is electrically
compatible with existing 12V drivers. It is a major
addition to the portfolio for
small A/C units and extends
an already well-established
portfolio of components
for a wide capacity range of
CRAC units, which include
compressors, controls and
sensors, system protectors
like filter driers, ball and
check valves and microplate
Heat Exchangers in
WC systems.

KIT FOR EVALUATING INDOOR AIR QUALITY
With the testo 440 CO₂ kit with Bluetooth, all indoor air
quality (IAQ) related parameters for evaluating indoor air can
be measured and docum ented
wirelessly. The testo 440 Air Velocity
& IAQ measuring instrument
recognises probes automatically,
and its structured measurement
menus simplify the adjustment of air
conditioning and ventilation systems.
Up to 3 probes can be connected
simultaneously to the measuring
instrument: a Bluetooth probe, a wired
probe and a temperature probe with
Type K thermocouple connector. The
versatile Bluetooth handle allows the connection of many different
wireless probe heads for all applications. In addition, the kit contains a
CO₂ probe head and a storage case.
The kit features:
• Structured measurement menu for long-term measurements
• Parallel determination of CO₂ concentration, air humidity and
air temperature
• Absolute pressure compensation, calculation of wet bulb
temperature, dewpoint and absolute humidity
• Wireless probe, internal data storage and USB port for data
export
• Can be extended with a large portfolio of digital probes
