Did you know…COPPER-RICH™

COPPER-RICH™ has many uses on the job, in the shop or even around the house.  From super high voltage SS Kearny’s to low voltage wire nuts. It copper plates the connection helping protect against normal expansion and contraction due to the heat of electrical current.

A great tool in connections between copper and aluminum wiring to help prevent overheating and oxidation that is prevalent in such dissimilar metal connections. Other battery or electrical connections, particularly in extreme climates, can benefit from a coating of COPPER-RICH™ as well. How about your lug nuts on the boat trailer? Need some corrosion protection as well as anti-seize? Then checkout COPPER-RICH™ or maybe one of our other anti-seize products like Break-Out™ here

HRV issues/Condensation on ducts.

Stenas asks: I moved into this house in February and it was fairly cold last winter. We’ve had a bit of a cold snap and its been 14 to 30ish for the last week. I went downstairs and noticed a puddle of water on the floor and checked the HRV until above it. There is water dripping down the ducts.

I cleared out the closet and the water is dripping from under the duct insulation (grey wrap tapped at the ends, tape seal was/is loose).

I know this is an issue but is there anything I can do in the interim while I wait for a HVAC contractor to come out?

As an aside: the unit is a Venmar Constructo 1.5ES it hasn’t really worked since I bought the house. If you turn it on its stuck in high mode and you cannot use the singular on unit button to change it to low or panel controlled.

Is the unit not being on adding to the problem?

Thanks

A: The condensation is caused by the surface dewpoint of the duct being below the dewpoint of the surrounding air. Insulate the duct with a vapour barrier. You could do it yourself.  – Deux1

RectorSeal® Introduces Safe, Quick and Easy Leak Sealant Injection Method– AC Leak Freeze® PRO

aclfpro-packaging-group

AC Leak Freeze® Pro is the leak sealant formula and applicator combination that’s safe for the HVAC/R service tech and the refrigeration system.

Houston–RectorSeal® LLC, a manufacturer of quality HVAC/R products, has introduced AC Leak Freeze® Pro, a safe, quick and easy refrigerant leak sealant applicator for residential and commercial refrigeration and air conditioning systems.

AC Leak Freeze Pro is an 11.5-inch-long applicator that consists of a flexible, easy-to-handle, transparent refrigeration hose and an attached copper reservoir, which contain a total 1.46-ounces of the same trusted, non-polymer, ac leak sealant formula as the renowned syringe-based AC Leak Freeze injector. Unlike some other disposable leak sealant applicators, AC Leak Freeze Pro doesn’t require a system pump down with R-410A systems and safely withstands all typical refrigerant pressures.

The Pro applicator is designed for use with 1.5 to 6-ton systems  and is available with both the blue AC Leak Freeze and green AC Leak Freeze with Magic Frost formulas, the latter which contains a compressor life-extending lubricant additive.

One side of the hose connects to the refrigeration system’s low side. The AC Leak Freeze formula is propelled into the system within seconds once the hose’s reservoir is connected to either the high side or a refrigerant cylinder via a charging manifold. The disposable, one-time-use, AC Leak Freeze Pro applicator’s nylon hose, brass fittings and copper reservoir are all 100-percent recyclable.

AC Leak Freeze Pro is the HVAC/R industry’s safest formula for service technician and the refrigeration system. It’s proven compatibility flows with refrigerant/oil to permanently seal small leaks and prevent them in the future. The patent-pending refrigerant leak sealant formula is not moisture activated, has a safer flashpoint rating than the competition, and doesn’t use polymers that can potentially clog compressors, recovery/evacuation units, Schrader valves, capillary tubes, TXV valves, micro channels or manifold gauges.

Other AC Leak Freeze Pro features are:

  • hose and reservoir are factory-sealed to prevent injecting air or atmospheric moisture into the system;
  • the nylon hose’s 45-degree connection fitting allows easier hand access than straight fittings in cramped Schrader valve environments;
  • transparent hose eliminates guess work as to when application is completed;
  • and boxed four-color packaging designed for distributor J-hook merchandisers.
