Kraus & Naimer Koolkuna visible contact isolators
Since 1907 Kraus & Naimer has maintained high standards and quality products and has established itself as an innovator leader in the switchgear market. The company has focussed on local markets and adapting to the needs of the customers has been at the forefront of each branch’s success. Maintaining the Kraus & Naimer standard of quality and customer service at the local level with local products has driven the international success of the brand.
The Australian market has seen an increase in the desire for many end-users to have a clear view of the moving contact within the switch to give the user complete peace of mind of the status of the contact. Kraus & Naimer maintains that the switch and operator has been extensively tested to ensure it conforms to local and international standards as a switch-disconnector so that if it says “off” – in is understood that it is turned off - however, we also listen to our customers and understand that sometimes they want to see it for themselves.
Kraus & Naimer already had a range of switches with visible contacts and a longstanding history of dependability, so it was simply a matter of developing a more suitable way of mounting the switch so the contacts could be viewed clearly. The innovative addition of an extra door hinging from the side meant proven and certified interlocking mechanisms could be utilised without the need for over-engineered designs that are prone to failure. The combination of established mechanisms with visible contacts means the user can be 100 per cent assured in the knowledge that safety has been effectively achieved and that reliability is completely assured. After all ¬ Koolkuna means “a place of safety”.
of COVID-19
Along with COVID-19 restrictions have been eased, just about any business you can think of that is open to the public has taken the initiative to protect their employees, customers and visitors by installing hygiene and safety barriers.
Allplastics fabricates and supplies safety barriers and screens made out of clear
Acrylic and Polycarbonate including Acrylic Sneeze Guards, Polycarbonate
Barriers and Framed Screens, seeking to minimise the risk of transmission of COVID-19 between employees and customers in public places such as hospitals, pharmacies, supermarkets, cinemas, clubs, restaurants, cafes as well as classrooms and offices.
Firstly, clear bent acrylic sneeze guards are made to the user’s requirements, generally from 4.5mm or 6mm thick acrylic with a base that can be attached to a counter or benchtop. Acrylic can be used in many cases because of its outstanding weatherability, long lifespan, excellent clarity and can be recycled easily. It is widely recognized with brands such as Perspex, Plexiglas is a rigid thermoplastic that’s more economic and shatterproof alternative to glass with half the weight of glass options.
Polycarbonate barriers are designed for applications where they need to be flat packed for ease of transport and for quick assembly. Polycarbonate in 4.5mm thick or 6mm thick is cut to shapes with matching slotted interlocking “feet” with double-sided tape. Polycarbonate is virtually unbreakable and 250 times the strength of normal glass. It offers the unique features of being lightweight and being virtually unbreakable ideal material for security glazing.
The third variation in clear barriers is designed to set the business back to work

by segregation of patrons in public places. Both clear acrylic (PERSPEX) and clear polycarbonate are used in thicknesses from 4.5mm, 6mm and 10mm depending on the situation. Allplastics can fabricate bespoke barriers to heights and widths suited for your specific use. In addition, the robust made in Australia partitions are portable with a strong powder-coated steel and durable casters built to last. This gives venues the option to easily relocate the barriers from one section to the other with ease. The partitions have clear polycarbonate inserts but can also be supplied as whiteboards or magnetic chalkboards.

Pressure sensing digital flowmeters monitor pressure and flow
EXAIR’s Pressure Sensing Digital Flowmeters provide a way for plant personnel to monitor pressure and flow throughout a compressed air system. A pressure sensor is mounted between the two flow sensing probes and the display can be configured to show air pressure or air flow. A transistor output can also be configured to provide a low-pressure alarm to protect your processes and equipment. Pressure values are capable to display PSIG or BARG. Measuring compressed air is the first step toward identifying high compressed air use areas, compressed air leaks and optimising air use.
Each meter ships with the necessary hardware and tools for installation including drill bit, drill guide and hex wrenches. The pressure sensing feature is available on 2” (51mm) or larger flowmeters. They are available in standard units which display airflow values on a bright LED screen, with optional data logger to capture and control the data. The pressure signal is also available through optional wired and wireless serial outputs. Airflow values are expressed in standard cubic feet per minute or cubic metres per hour.
Available from Compressed Air Australia, Pressure Sensing Flowmeters for schedule 40 iron pipe, Type L Copper and nominal millimetre sizes are available. They are CE and RoHS compliant and join EXAIR’s full line of digital flowmeters for air lines from 1/2” through 8” including hot tap, wireless and data logging flowmeters. If a process requires a liquid chemical or additive being incorporated into a flow of water or other liquid, a hydraulic driven metering pump should be considered. The MixRite PVDF Water Driven Metering Pump is of the highest quality and constructed from one of the most chemically resistant engineered plastics available – PVDF. The system works by plumbing in a water driven metering pump in the pipe work which will incorporate a liquid chemical or additive that is required in your process. The advantage of a water driven metering pump is that an additional fluid flow measuring device is not required. The water drives a hydraulic motor whereby each cycle is measured, and a precise volume of chemical is injected. The water flow can increase or decrease but the proportion of chemical being in injected remains the same. A 4-20mA flow meter with smart electrical metering pump is not required. This is because a water driven metering pump does not require electricity to operate. The biggest negative of using water driven technology in process work is ensuring the engineered plastics used in construction of the metering pump is compatible with the chemicals/additives used in that process. PVDF is similar to Teflon in regard to chemical compatibility, it is that good. PVDF models are an excellent option where the chemical blends being used are proprietary and full analysis cannot be confirmed. It is worth noting that chemical degradation of components is not a warrantable failure, PVDF provides the greatest range of chemical application. Consult Dosing Systems Australia for a consultative analysis of the most appropriate water driven metering pump for your process or application.
