TOOLS TALK – SPONSORED BY ASPEN PUMPS With the new variant of Coronavirus in the UK and cases rising, cleaning and maintenance of HVAC systems is more important than ever to minimise contaminants within these systems and ensure good indoor air quality. Covid killing chemicals – recommended by Advanced According to the European Centre for Disease Prevention in their latest update (November 2020), air conditioning can play a complementary role in decreasing the potential airborne transmission of SARS-CoV-2. This specifically references HVAC systems and corresponding AC units that are well maintained. Two-step process We would recommend a two-step cleaning process to be carried out every 3 months; clearing drains and cleaning coils. Doing both more regularly will make sure airborne contaminants, pathogens and dirt are dealt with more consistently. This 2-step programme may also need to be implemented more regularly, in some circumstances, due to some buildings having more highly tracked areas of people. A clean air filter protects the cooling coils from dust and dirt and regular cleaning of air filters results in proper cooling which reduces the breeding conditions needed for germs to proliferate and contaminate the flowing air. Furthermore, regular maintenance ensures maximum eciency of units and better indoor air quality. A 2006 ASHRAE study showed that maintenance schedules improved energy eciency and the IAQ performance of the buildings HVAC/R systems by up to 10 – 15%. Advanced recommend; Step 1: Clear drains - DrainKleen OneShot & DrainKleen Step 2: Clean coils - Condencide, RTU ECD, EasyCare & AdvancedGel ECD – spray coil and leave for 15 minutes to eectively kill and remove 99.9% of bacteria, fungi, mould/spores and viruses. This will also allow general dirt and all types of contamination and soils to be agitated and loosened in the cleaning process. They have been working to ensure that certain products meet the EN standards which verify that these products could eectively kill the virus during the cleaning process. Those particular products meet EN 14476:2013 + A2 2019, which states that they can kill all 7 of the known human Coronaviruses, as well as the new variant of the virus. At the point of contact, these products kill the SARS-CoV-2 virus (which leads to the Covid-19 disease). Advanced specialist cleaning products can demonstrate that they kill and remove all types of bactericidal, fungicidal and virucidal activity. Furthermore, cleaning chemicals get right through the A/C unit, making it a most eective method for deep cleaning. https://www.aspenpumps.com/en-gb/ advanced CMYK / .ai CMYK / .ai CMYK / .ai acrjournal.uk 07
