Products 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 For more information, contact +27 (0) 11 380 8060 VIRUSES, BACTERIA, UVC LIGHT SOLUTIONS Legionella, listeriosis, mould, algae, and we haven't even mentioned Covid-19 yet!
