Difference Between Platinum and Silver range:

Our Silver range is essentially a budget version of our Platinum range but we ensure that the quality is very similar. The chief differences between the direct cylinders are:

  • The lagging is of standard quality, not top-of-the-line as with the Platinum range
  • The stainless steel used is slightly thinner (by about 0.1mm), however the same quality duplex stainless steel, and is built to withstand the pressure required for an unvented cylinder.
