ENVOTEC Dielectric Union 2″ Female x Female Steel X Brass

Dielectric Unions are designed to be installed between pipes of dissimilar metals to avid electrolysis, which leads to corrosion and pipe failure.

Applications:
Dielectric Unions ca be used on all installations of heating, air conditioning, hot water storage tanks, chilled water processing tanks, FCU’s and AHU’s

Why use Dielectric Unions
Electrolytic corrosion occurs in plumbing systems that contain dissimilar metals. Copper present in a heating system is a metal that dissolves very easily. Waterborne copper particles thus circulate in the heating network and come in contact with the other metals forming an electric pile phenomenon. Water and the 2 dissimilar metals form a battery where the electric current carries ions from one metal to another causing it to dissolve.
