Dairy Cylinders

Hot water heating can account for up to 40% of the average dairy shed’s energy use, so it is important to choose a Dairy Hot Water Cylinder that delivers energy efficiency, optimum temperature and strong water flow.

Our Dairy Hot Water Cylinders are manufactured from heavy gauge copper, increasing resistance to corrosion and providing long life durability of the cylinder.

Key features include:

  • M.A.F. approved
  • Heavy gauge copper
  • Swaged barrels for increased strength
  • Manufactured to NZ Standard 4604
  • 50mm foam insulation resulting in lower power usage
  • 180 – 1000 litre capacity available for new or replacement installations
  • 2kw and 3kw elements in various combinations
  • Sight tube, fittings and valve kit included

Our superior design and manufacturing quality ensure that our Superfinelite Dairy Hot Water Cylinders provide a long life, high performance hot water supply for the dairy shed. So confident are we of the quality of our Dairy Hot Water cylinders that we provide a five year warranty when installed in accordance with all relevant building codes and standards. The cylinder itself is guaranteed for five years, and the remaining parts of the unit carry a 12 month warranty.
