2 Dwyer handles the heat

The Dwyer Series AT-3000MR/MRS, an ATEX/IECEx approved Photohelic switch and gauge, incorporates a flame-proof aluminium enclosure that protects the device for use in hazardous areas commonly found in process or industrial applications. The multi-purpose 3000MR/3000MRS Photohelic device contained in the Series AT-3000MR/MRS is designed for monitoring pressure, vacuum, and differential pressure. Solid-state switches allow for switching in high-cycle rate applications and are designed to extend the life of the sensor. These products can be installed in varying process or HVAC applications globally because of the numerous pressure ranges and units available. Suitable for industrial applications, the Series AT-3000MR/MRS incorporates a cast aluminium enclosure with texture epoxy coating. It also features a standard windowed enclosure cover that allows users to visually verify changes in the process. Go to: www.dwyer-inst.com.au ■

3 The air up there

Daikin has launched the Compact R32 SkyAir Cassette, in line with its commitment to release more products with low-GWP refrigerant R32. Suitable for commercial, retail and office-based applications, the new SkyAir light commercial range features a flat compact fascia that fits into a standard ceiling tile; optional intelligent sensors for greater energy efficiency and comfort; built-in drain pump; and individual discharge flap control. The R32 SkyAir Compact Cassette range consists of five models from 2.5kW to 7.1kW. End-users can control the system from their mobile or tablet device via the optional Airbase WLAN module (BRP15B61). The app is available for both Apple and Android devices and supports up to 10 indoor units connected to the same network. Each unit requires an adapter. Go to: www.daikin.com.au ■

4 Inova’s kitchen helper

Inova has announced the Australian release of Lepido, a system that recovers energy from restaurant and kitchen ventilation. According to Inova, the system recovers energy from waste kitchen exhaust air, and generates both heating and cooling outputs in order to lower buildings’ energy consumption and reduce CO2 emissions. Manufactured by Swedish technology company Enjay, the patented system purportedly features technology that enables the heat exchanger to survive in harsh kitchen environments requiring little ongoing maintenance. Lepido is available in multiple sizes with flows ranging from 800–5,000L per second of exhaust air. Applications include restaurants, clubs, health and aged-care facilities, shopping centre food courts, and maritime vessels. Inova is looking for suitable pilot programs to demonstrate the value of the system in the Australian environment, and welcomes enquiries from industry professionals. Go to: www.inovacorp.co ■

5 Condair expands range

Humidity control specialist Condair has extended its dehumidifier range to include more desiccant models, wall- and ceiling-mounted systems, and units that control temperature as well as humidity. The Condair DA desiccant dehumidifier range includes capacities from 0.6 to 182L/Hr (@20°C/60%RH) from its standard models with customised units able to meet larger drying requirement. Units can incorporate on-board touch screen PLC controllers with high-level supervisory connectivity. For process airflow greater than 500 m3/hr (DA-500), AC or EC fans are available, with the regeneration fan positioned prior to the desiccant rotor in a push configuration. The company says this avoids contact between the fan and the hot humid exhaust air, prolonging the life of the fan. The rear wall-mounted systems can be remotely located in a room adjacent to the area being dehumidified. Humid air is circulated to the dehumidifier and dry air fed back to the room via the rear wall connection. Ceiling-mounted models enable installers to either integrate the unit in a suspended ceiling system or simply fix it overhead to avoid taking up floor space. Dehumidifying capacities range from 49 to 190L/24hr (@30°C/80%RH). Go to: www.condair.com.au ■

6 Infinity and beyond

Fujitsu General is adding an 18kW high-static three-phase ducted air conditioner to its Infinity range. This will provide installers with a new option for projects with limited space outdoors and in the ceiling cavity. This 18kW option includes a narrow 480mm outdoor unit and lightweight (69kg) indoor unit. The narrow outdoor unit provides more options when finding a suitable location, while the lightweight indoor unit offers installation flexibility and is less labour-intensive. The system can be separated into a fan unit and heat exchanger. The company says this makes installation within the roof cavity of existing homes easier. An optional Truss Transition Kit can assist when installing the indoor unit around and between existing roof trusses. The new 18kW Infinity ducted air conditioner is compatible with zone control and the Fujitsu General anywAiR technology ducted controller. Zone control ensures different areas in a unit or home can be set up for optimal indoor comfort and energy management. Go to: www.fujitsugeneral.com.au ■

7 Air defence

The AP BIO air purifier comes from Fläktgroup, a European supplier of energy-efficient indoor air technology solutions. The air purifier is available in three sizes: 500, 1,000 and 2,400m3/h. All feature the AirFend technology that is designed to filter and eliminate bacteria and viruses. AP BIO is a three-stage filtration air purifier that purportedly delivers Biocell deactivation of bacteria and viruses in a short time period.

Tested according to the EN14476 + A2-07-2019, the unit is said to hold back 99.995 per cent of all pollutants and offer a safe solution against COVID-19 with its HEPA14 filter. The company says that the biologic AirFend technology can minimise the risk of transmission by deactivating virus-contaminated aerosols, the main carriers for coronaviruses. The AP BIO is distributed in Australia by Vekavent. Go to: www.vekavent.com.au ■

8 Sentinel against virus

Halton has designed Sentinel, a mobile ultraviolet germicidal irradiation (UVGI) solution to minimise viral spread and protect personnel and guests in indoor spaces. According to the indoor air solutions company, the new mobile filtration unit complements and enhances the effectiveness of current mitigation practices – such as social distancing, respiratory masks, hand washing and updated sanitation practices. With a long history as a tool for minimising viral spread, UVGI products are popularly used in the health-care segment. “Through careful selection of UV tube glass and safety controls, the wavelength of the UV light emitted in the Halton Sentinel UVGI unit specifically targets the COVID-19 virus without producing the respiratory irritant, ozone,” says Halton. “Air from the room is drawn into the Sentinel filtration unit for the critical exposure dose of UV to inactivate viral, bacterial, and fungal organisms and then the treated air is filtered through MERV 13 filters for return to the room.” Sentinel is recommended for use in indoor environments without openable windows – where it can purportedly reduce the risk of airborne transmission by over four times.
