Pacific Ventilation says the DELTRI+ filters are Eurovent certified, and contain advanced plasma technology capable of neutralising or destroying 99 per cent of all viruses. This includes SARS-CoV-2, as tested by the Luxembourg Institute of Science and Technology. “With the DELTRI+, building owners can quickly improve existing units before considering more extensive upgrades to their ventilation systems,” says Pacific Ventilation. “Compared with other methods utilised for virus prevention, the DELTRI+ filters offer a more straightforward solution that is easy to apply and manage.”

Dwyer’s photohelic focus
Fitter filters with Aeris
Australian company Aeris Environmental has developed a new polymer coating for HVAC filters designed to prevent the spread of airborne viruses, including COVID-19. Aeris Guard Bioactive Filter Treatment contains a readily biodegradable active biocide that the company says kills 99.99 per cent of bacteria and viruses, including SARS-CoV-2 on the polymer coating.
Dwyer Instruments has released the Series AT-A3000, an ATEX/ IECEx-approved photohelic pressure switch/gauge. “The flameproof-approved Series AT-A3000 ATEX/IECExapproved photohelic pressure switch/gauge functions as a versatile, highly repeatable pressure switch combined with a precise pressure gauge employing the time-proven Magnehelic gauge design,” says Dwyer.
“A single application helps control and prevent the growth of bacteria and mould for up to 12 months,” says the company. “In addition, the Aeris filter treatment significantly improves the ability of dust filters to remove even finer dust particles than before treatment.”
The device measures and controls positive, negative or differential pressures of air and compatible gases. Two photo‑transistor actuated, DPDT relays are included for low/high limit control. Set-point indicators are controlled by knobs located on the gauge face (accessible opening case after de‑energising instrument). Set-points can be interlocked to provide variable dead band, which Dwyer says is ideal for control of fans, dampers, and the like.
CO2 is increasingly being used as a refrigerant for supermarkets, industrial freezers, cold storage and heat pumps, among other applications. Wilson ECO2 uses specially manufactured heat exchange coils because transcritical CO2 systems can produce high temperatures and pressures. The coils are high finned to provide efficient heat transfer to the heating hot water within the vessels and ultimately to the system. The vessels are available in a range of sizes using multiple heat exchange coils offering bespoke solutions. Wilson says they can also be designed and engineered to project specific requirements and kW ratings.

Something new for CO2
Wilson Hot Water has developed the ECO2 range of transcritical CO2 heat recovery vessels, manufactured in Australia.
The filters are available in Australia and New Zealand exclusively from Pacific Ventilation. “Operators do not need to worry about significantly increasing energy costs with this solution,” says Pacific Ventilation managing director Peter Gibson, Affil.AIRAH. “Despite its virucidal functions and being classified ISO16890 ePM1 90 per cent, the filter holds a Eurovent Certified Performance A+ energy class rating.”
do not require expensive safety and monitoring measures. They also feature LED lighting, low noise output of 52dB, and a simple-to-clean condenser.

Aeris Environmental chairman Maurie Stang says the new product could improve air quality on public transport and help ensure safer travel. “Transport authorities should consider solutions that improve indoor air quality, are scientifically proven, and compatible with existing HVAC systems,” Stang says.
“Gauge reading is continuous and unaffected by switch operation, even during loss of electrical power,” says Dwyer. “Flameproof enclosures are available in aluminium, with a glass window, which allows for viewing of set-point needles and process pressure.”

Avem Quirks offers the works
Australian supplier of refrigerated cabinets Avem Quirks is offering a new model that it says represents a first for energy efficiency. “Pastorfrigor’s Genova Overview model is the first commercial refrigerated wall display unit in the world to achieve Energy Class A, with Class A being the most efficient rating according to the rigorous Energy Efficiency Index (EEI),” says Avem Quirks. “Energy consumption based on a Genova OV 75 H205 GD 2500 unit is a minimal 9.3kW for both M1 and M0 options. This level of performance means that it uses approximately 62 per cent less energy than a standard glass door multideck unit.” According to Avem Quirks, as well as saving energy, the units are easy to maintain and, because of the low refrigerant charge, 6

ABB’s efficiency drive
The product caters to the growing demand for greater efficiencies as regulations continue to tighten on the total system for fans, pumps and compressors. It is designed to achieve the highest system efficiency possible from wire to air, while using sustainable materials. ABB says the Baldor-Reliance EC Titanium product line utilises Ferrite Assisted Synchronous Reluctance (FASR) technology using non-rare-earth magnet materials to meet and exceed IE5 efficiency. It is suitable for constant and variable torque applications, across a wide speed load range and above base‑speed conditions. “The EC Titanium product line is economic and efficient, even at partial loads where most fans operate,” says the firm’s David Barnard. “The real advantage is that efficiency stays high at any speed … allowing for greater fan design optimisation.” Go to campaign.abb.com/ectitanium ■
