Total control from Dwyer

The Series WPTN Multi-Jet, NSF Certified plastic water meter is a new series of plastic mechanical water totalising meters from Dwyer Instruments.

The meters display the total water usage in gallons. They are available in a range of body sizes and include NPT optional couplings. The plastic body water meters can be used where standard brass is not compatible, in potable water applications, some corrosive environments, or where an economical water totaliser is desired.

Product applications include potable water, commercial water usage, chiller water usage and irrigation.

Diamond disinfectant

BlueScience is a UV air disinfection system from BlueDiamond Pumps. The retrofit system provides UV-c LED technology for all existing AC equipment to treat and protect the air by constant disinfection every time it passes through the unit.

According to BlueDiamond, the system works through a process of germicidal irradiation. The UV-c light attacks the DNA/DNR of micro-organisms, killing 99.9 per cent of them and rendering bacteria and viruses harmless and unable to reproduce or spread.

Unlike most UV-c products that are aimed at the ducted ventilation market, BlueScience is aimed specifically at fan coils and mini-splits.

According to BlueDiamond, the system can be installed inside an existing or new wall split unit, and the retrofit unit can convert any new or pre-installed mini-split or FCU into an air sanitiser.

The standard model consists of the driver and 700mm UV-c LED strip. This model can be used on mini-wall split AC units up to 10kW. For FCU units up to 23kW, users can opt for a Pro Kit with 30 UV-c LEDs in addition to the standard model.

Frese hits a six

Valve developer Frese says it has found a way to reduce the number of required valve components through the Combiflow 6-Way.

With the Combiflow 6-Way component, the company says that only one valve and one actuator is required to achieve complete pressure independent balancing and control.

“One actuator means only one data point versus conventional six-way valves that need to be coupled with additional PICV and actuator for similar control or manual balance valves and DPCV with lower authority flow control,” says Frese.

“This is possible because Frese has directly built in the differential pressure control into the 6-way valve, and turned it into a compact all-in-one solution. Frese has a patent pending on this integrated technology.

The Frese Combiflow 6-Way is controlled by a rotating actuator with Modbus or analogue control. Notably, it enables remote commissioning via the BMS.

The company says that by requiring fewer fire penetrations, less pipework, fewer data points and reduced fan coil costs, the new design also has the potential to reduce building costs.

Good thing, small package

The Series EDA Electronic Pressure Controller from Dwyer Instruments is a compact package that can replace a separate gauge, two switches, and a transmitter in a system. The company says the product design saves money and installation time while conserving panel space.

Now available with 120-240 VAC capability (viaHV option), the Series EDA can be ordered for line voltage applications. With the “-HV” option, the EDA can be powered with 120-240 VAC, eliminating the need for a step-down transformer and reducing the installation time, cost, and complexity in applications where only 120-240 VAC power is available.

Key benefits include simplified ordering, quick set-up and diagnostics, weatherproof construction, and versatile pump skid applications.

Care for your air

In conjunction with AirTemp, Power Clean Air Products has launched a new range of Airtemp Air Sterilisers.

Available in three sizes – for commercial, home and personal use – the devices are designed to inactivate airborne viruses, remove odours and ultra-fine particles.

According to Power Clean Air, Ultra Plasma ion Fields and e-Nano Electrostatic Filters decompose and remove viruses and bacteria including coronavirus, staphylococcus, influenza and candida, with an efficacy of 99.9 per cent.

The company recommends the device for rooms up to 84m3 that require air sterilisation. The units are aimed at single-room applications up to 81m3 where viruses can be easily managed. Larger capacities are available on request.

Power Clean Air offers a range of air and surface treatment products including the Aircare Air Purifier as well as cleaners and sanitisers for air conditioning filters and coils.

Go platinum

The Platinum 3D is Teco’s latest range of DC inverter wall-mounted split systems.

Featuring a four-way auto swing, the unit circulates air to more areas of the room. Built-in wi-fi enables control from outside the home.

The “I Feel” mode senses the temperature based on the location of the remote control. Teco says this gives a more accurate read, compared to a sensor on the high wall unit.

The Platinum 3D range also features an advanced statically charged filter system that helps reduce the circulation of airborne contaminants, as well as a self-cleaning function. According to Teco, Gold Fin protection on the indoor and outdoor unit assists with longevity and performance of the system.

Registered and approved under the latest determination of MEPS, the Platinum 3D (2.6kW) is rated on cooling at 6.5 Stars in Sydney, 7 stars in Melbourne and 9 stars from Brisbane to Far North Queensland.

Get in the zone

The iZone smart air conditioning system maintains home air quality with sensors that monitor the humidity, CO2 and volatile organic compound (VOC) levels present in the air.

It has been designed to improve general health and reduce symptoms such as headaches, fatigue, asthma, allergies, coughing, dry skin conditions and shortness of breath.

iZone’s iSave can automatically respond to high humidity by turning on an outdoor compressor to reduce humidity and cool the home. As temperatures drop and humidity levels decrease, the air conditioning system reverts to outside air cooling.

The system can also detect VOCs, such as gases emitted from household cleaning substances. Once the system flags unsafe levels, action can be taken to reduce exposure by opening a window or triggering other smart appliances to turn on – such as an air purifier, a fan, or a dehumidifier to help improve air quality.

Quick on the draw

Revit software users can now use the free Revit plug-in to save time and reduce data transposition errors when selecting the most appropriate ventilation solutions for their mechanical drawings. Revit is a drafting tool that enables a streamlined method of adding HVAC equipment to drawings.

DO YOU HAVE A NEW PRODUCT TO GO IN THE TOOLSHED?

Pacific Ventilation has designed the plug-in to automatically bring in fan information to drawings when used with the company’s fan selection software, FansSelect. It saves every change so you can swap different fans in and out of your plan as long as you have grabbed the .fsx files from FansSelect.

Users can create the fan selection output on their own or call their local branch for a copy of the job file. To use with Revit, the plug-in only needs to be installed once, as the tool encompasses an automatic update system.

Under the pump

The PUMPCALC is a centrifugal pump analysis program from AWDABPT that can be used to predict the performance of one or more centrifugal pumps, at various impeller sizes, speeds and series or parallel configurations.

The main data needed for running PUMPCALC is the pump performance data. This consists of sets of values of flow rate (or capacity), head and efficiency for a particular pump, and for a specific impeller size and speed.

Normally, this information is available in a pump catalogue. The number of sets of flow, head and efficiency values are limited to between three (minimum) and 15 (maximum) sets of points. The data points taken off a manufacturer’s pump curve must cover the entire range of flow rates permissible for the specific pump.
