Feature TOOLS AND TOOLING: FOLLOWING TRENDS, BLUETOOTH CONNECTIVITY AND BEYOND By Benjamin Brits No matter what the area of specialisation of your business, the HVACR sector requires a substantial toolbox for technicians as products are continually improved to cater to changing market needs. The topic of tooling is so vast it could essentially fill an entire publication. In this article we aim to highlight some new tooling and trends that could assist in how you consider your tooling setup in the current environment. As you would know, the better efficiency you can work towards, the more this translates into savings, and savings into a competitive advantage. The tools and tooling required for ventilation, new installations or maintenance jobs will no doubt be very different, and most technicians will favour a particular or preferred set of tools to perform their jobs, some preferring traditional tools and some embracing the advancements that technology offers. There are naturally basic tools and tooling that will be applicable to all technicians such as hammers, pipe cutters, plier sets and screwdrivers, but technicians require a much broader set of tooling as they are often required to do various overlapping tasks that may include sheet work, pipe work, working with refrigerants and electrical work. Generally, this type of tooling is available in kits or tool-bags from reputable suppliers. As much as I’m sure you are tired of hearing about Covid-19, it has turned things upside-down all over the world, from manufacturing plants to simple things like the way we have to interact with others. It has also highlighted awareness around building-health where the HVACR sector plays a significant role, and where building designers now have a special focus on airflows and social distancing for the future. SOME NEW ESSENTIALS, SOME ESSENTIALS TO REVISIT Cleaning and disinfection The inside of an air-conditioner or ventilation system is arguably a perfect spot for many kinds of pathogens, being moist and warm – and not just limited to the latest coronavirus because that is what is part of almost every discussion at the moment. Rothenberger South Africa now offers a new product for the sector – a portable spraying backpack holding a 15l capacity, where you mix in the required amount of detergent/ disinfectant/antiseptic liquid for cleaning and disinfecting of HVAC systems. The backpack works with the cordless alliance system (CAS) rechargeable battery, so the battery is also multipurpose and compatible with other CAS tools and the statistics indicate at least 100l of spraytime, while maintaining a particular pressure via the electronicallycontrolled pump. It has three different types of nozzles, a direct strong spray for harder surfaces, an intermediate spray, and a very fine mist spray. The direct hard nozzle is used on the external side of the building to clean out the outside parts of an air-conditioning (AC) unit. The intermediate nozzle is used predominantly for inside of buildings, inside AC units and vents. The mist nozzle is for smaller units and cleaning of the sensitive condenser fins. Probe sets Testo South Africa has introduced a new refrigeration smart-probe-set that allows measurement of superheat and subcooling via your phone at distances of up to 100m. If you have a very large system you are able to, for example, put one probe 50m from another probe while you stand in the middle with your smartphone and select the probe you want to access the data from. Rothenberger The Rosani Clean 15 supplied by Rothenberger has stainless steel components suitable for use with various disinfectants. www.hvacronline.co.za RACA Journal I September 2020 29
