Mercad Equipment Inc

Main and Pin Cathodes

Retrofit your anodically protected H2SO4 Coolers with long-lasting Mercad Equipment Inc. Super Cathodes. These cathodes are designed to be installed in your coolers without any modification of the seal assemblies and will provide the following improvements over OEM:


  • Substantially larger cathode surface contacts the acid and provides better and more consistent current distribution over the entire anodically protected acid-wetted surfaces.

  

  • Reduced electrical resistance and consequently lower voltage drop is obtained due to the larger diameter rod. This improves voltage distribution and millivolt readings around the vessel.

 

  • Lower maintenance cost due to the extended life of the cathode rod, consider 2~3 times longer life expectancy than that of the older technology, sheathed style of cathode. This life expectancy is the result of the larger metal volume and the lower current density at the surface of the cathode. The Mercad Equipment Inc. Super cathode is ideal for those plants wanting to extend the interval between major shutdowns.

 

  • Savings on service expenses is realized with Mercad Equipment Inc. cathode assemblies as you will need only minimal down time for inspection and cleaning since there is no PTFE sheath and perforations to become fouled or damaged. The bare surface of the Mercad Equipment Inc. Super cathode is easily inspected for corrosion and can be cleaned with a swipe of a wet cloth.

  

  • Improved Anodic Protection control of corrosion due to the more uniform electrical current distribution available throughout the anode surface of the vessel.

  

  • Prices are generally equal to or less than OEM cathodes, and when you factor in the extra life expectancy, you realize a huge saving on these consumable spare parts.
