In this live podcast from AHR Expo 2022, John and Mike Pastorello of Refrigeration Technologies give us a history lesson in HVAC chemical chemistry. They also explain what it takes to make a truly beneficial product for the industry. From the beginning, Refrigeration Technologies has focused on solving problems instead of jumping on product trends. Before Big Blu was introduced, technicians had to rely on less-than-reliable electronic leak detectors and poor-quality soap bubbles. So, John Pastorello learned about the fundamentals of foaming and bubbles to create a leak reactant that works, even creating microbubbles for tiny leaks. Nylog has a similar origin story, and it has evolved to work for both mineral oil (red) and POE (blue) systems. As with Big Blu, John ran several tests to make sure the Nylog was compatible with HVAC equipment and did not cause contamination. The Viper Pan & Drain Treatment was developed to replace pan tabs, which failed to remove the dead biological material in drains. The spray coats the whole pan and dissolves sludge with enzymes. The Venom Packs are highly concentrated cleaners that arose from a move to consolidate the chemical line into something lighter, smaller, and faster. (Think about laundry detergent pods.) So, Venom Packs were inspired by laundry detergent and developed into a concentrated product line with recommended dilution ratios. Mike, John, Jessica, and Bryan also discuss: All the considerations that go into creating a leak reactant "Controversial" uses for Nylog Nylog white pipe dope for gas, water, air, and glycol Overcoming drain/pan odors Enzyme-based cleaning Safety considerations with HVAC chemicals Durability of Venom Pack packaging Family businesses Women in the business Learn more about Refrigeration Technologies at refrigtech.com.
