Edward coils water to refrigerant condensers & evaporators are all UL listed. The Edwards coaxial tube in tube heat exchanger consists of longitudinal, spirally wound applied fins, solder bonded to the inner tube with an outer tube serving as a shell. For best heat transfer systems contact us.
Packless Condenser / Heat Pump CoilsPackless coils utilize a coaxial "tube-in-tube" design. Water flows through the inner tube while refrigerant flows in the annulus between the inner and outer tubes. The key to the high performance of Packless coils lies in the convoluted multi-lead inner tube manufactured in a patented process.
