Did You Know that highly flammable refrigerants such as R290 and R600 are making their way into residential refrigerators, commercial coolers, ice machines and even freezers? I've even seen R290 residential heat pump chillers in the UK, and heard rumors of large quantity R290 residential applications here in the US, up for building code consideration. In this episode we discuss the advancement of these highly flammable refrigerants and introduce you to a new source for A3 tools and training with our friends at Nu-Calgon. Thanks for joining in!!
