Summary

John Pastorello from Refrigeration Technologies returns to the podcast to talk about selecting proper cleaners for various HVAC/R jobs.

From the beginning, the goal of Refrigeration Technologies has been to make cleaners that are safe but have the same effectiveness as the strong, hazardous varieties in the industry. The more hazardous cleaners are not food safe and may be corrosive, dangerous to inhale, or irritating to the skin or eyes. Some cleaners can also damage components; brighteners aren't recommended for use on aluminum coils for that reason.

John is a fan of foaming cleaners because the foam gives the cleaner more contact area and holds the detergent in place for a longer time. Foaming cleaners tend to be good for degreasing. However, if used improperly, the foam can overflow in the drain pan and get messy.

Many residential and light commercial HVAC contractors may benefit from keeping Viper EVAP+ for evaporator coils, Heavy Duty for condenser coils, and Brite only when there is an extremely dirty condenser coil. The Viper aerosol coil cleaner can also work well for small systems. The Pan & Drain Treatment also keeps drain sludge and odors at bay inside condensate lines and pans.

Instead of relying on harsh chemicals to dissolve microbial growth, Refrigeration Technologies cleaners help use enzymes to dissolve odor-causing biological material in HVAC systems.

John and Bryan also discuss:

PPE to use when working with cleaners
Acid-based cleaners and "non-acid" cleaners
Dwell time and contact
Dilution ratios
NSF registration and what it means to be "food-safe"
Viper Venom Packs

0:15.6	They make all kinds of great products and chemicals for the HVAC trade.
0:19.3	Specifically one that I love is called Wet Rag.
0:22.1	Wet Rag kind of works like a wet rag, but it's easier to use. You can pack it around valves. You can use it to protect the liquid line dryers and compressors or
0:30.3	whatever you happen to be braising in.
0:33.0	And then when you're done, you can just return it to the canister.
0:35.9	If you need to rejuvenate it, just use a couple little drops of water in it and it will rejuvenate
0:40.7	and be ready to use next time.
0:42.6	That is wet rag from refrigeration technologies.

0:51.9	Navac and Navac Global.com, makers of the NTE 11L break free power tubing expander.
0:59.5	So if you're used to using the tubing expander, lever swedges, that sort of thing, even the compact ones, you know that sometimes
1:05.4	it can take quite a bit of effort and it can be pretty tight to get into those tight spaces.
1:09.4	The NTE 11L is a first in class battery powered tubing
1:13.6	expander. Really excellent device on one battery charge you can
1:17.9	get 200 expansions and it only takes 12 seconds to expand a tube.
1:22.1	The NTE 11L comes with many of the most common sizes and you're
1:26.2	just going to love it. Really great tool and it's going to help you make your swedges even
1:30.2	easier than needed before with the NTE 11L from Navac.
