NOTES
• Coating loading may be adjusted to suit a particular current density or design life
• Standard anodes are designed for 20 year life, however, design life of up to 50 years can be catered for.
• Tubular MMO anode strings can be supplied to Clients specific requirements.
• Other tube diameters are available on request,16mm dia & 32mm dia.
