Remanufactured Circulators Are Machlett's Specialty

The same premium materials and components found in new Machlett circulators are employed to remanufacture Ferrite, AMTek and other brand circulators. Remanufacturing is done by ISO 9001-2008 certified Penta Laboratories to the industry’s highest standards. Some upgrades include:

  • Refinishing the entire unit with a fresh dipped iridite coating (includes the keepers that hold the magnets and domes in place)
  • Exclusive use of premium grade ferrite material
  • Cheaper aluminum domes are replaced with copper domes to prevent leaks from oxidation and enhance service life
  • Units tuned to tighter specification than when new
