We get a lot of questions about both evacuation procedure and TXVs so last week we produced videos on both topics, including: • Before and after testing of piston vs. TXV • Using the Bluvac Measurequick app • Use of core remover tools for evacuation • Flowing nitrogen • creating an external equalizer port and […]

When I started in the trade, the idea of flowing nitrogen while brazing was nothing more than the punchline of a joke. Like pulling a vacuum with a micron gauge or proper recovery, it was a wink and nod proposition rather than a real practice. I've had to unlearn many bad habits since those early […]

Before we convert temperature scales, let's take a step back and think about what temperature is in the first place. Temperature is proportional to the average kinetic energy of the random microscopic motions of the constituent microscopic particles, such as electrons, atoms, and molecules. Translation: Temperature is the average “movement energy” of the molecules in […]
