The scale problem
The Scale Problem
Scale layers in pipes and heating elements

The scale problem
The Scale Problem
Water hardness: The higher the concentration of calcium-
carbonate in the water, the higher the “water hardness”
(Measured in ppm, °dH, °fH)
Scale causing typical problems
• Loss of energy due to longer heating times
• Destroyed heating elements and heat exchangers
• High costs of repairs and maintenance of machines
and equipment
• Loss of water pressure due to reduced pipe
diameters
• High cleaning costs and the need of aggressive
cleaning agents
• Decrease in overall industrial productivity
• Sometimes complete failure of the water system

Diminishing energy transfer due to scale deposits
The Scale Problem
Example of an oil-powered boiler system
Energy loss in relation to layer of scale
(in mm) in an oil-powered boiler system
Example: A 500 kW-boiler system at 3mm
scale looses 50 kW (20%) at the transfer
Scale blocks out the heat energy
transfer:
Copper 372 W vs. Scale: 2,2 W
Heat-transfer-drop of factor 170:
causing a large increase in
heating times in a boiler

Fighting scale: your options
Water softeners
Softens the water chemically
Makes water soft 100%
Uses chemicals
High in maintenance
Vulcan
Physical water treatment
Hinders scale from forming
Manages the scale problem
No use of chemical
No Maintenance
Electricity use mInimial (3W)

The 3 Vulcan effects
1. Vulcan stops scaling on surfaces
2. Vulcan sanitizes the piping system
3. Vulcan protects against
rust and corrosion

The Vulcan Series
Vulcan protects against:
• Scale
• Rust and corrosion
Electronic scale protection system with
German CWT impulse-technology (24 V)
Eco-friendly system: no chemicals or salt
Vulcan operates maintenance free
Easy do-it-yourself installation (outside of the pipe)
Vulcan works on all pipe materials
(iron, copper, plastic, PVC, etc.)
Pipe diameter from 1” up to 20”
