Non Chemical Water Treatment Equipment
We are the manufacturers and suppliers of
Non-Chemical Water Treatment Plant. This equipment do not require any kind
of chemical for the removal of scale from hard water. In this equipment,
Scale Off part consists of a pipe with a special alloy core inserted inside.
The unit comes in different sizes and flanged as required - (see the
specifications). In order to prevent scale from forming in a piece of
equipment the scale off is installed in the pipe lines which feeds water to
it. The secret of its success is found in the core - its shape, its
composition and a combination of the pressure changes and turbulence that
the special design causes.
The scale off operates as a catalyst using the pH rise generated by the
alloy to trigger precipitation of calcium carbonate in the bulk of the water
forming stable crystals. This result is a water which has less calcium
carbonate in solution and a mass of seed crystals which, should the water
then be heated, act as sites for further precipitation in preference to
adhering to the hot surfaces - thus protecting them from scale.
The formation of scale caused by hard water in pipe work and equipment is
costly and seriously reduces operating efficiencies. Scaling and its removal
manually or by chemicals can cause damage to equipment.
Generally the application of chemicals has been the traditional method of
handling these problems - however increasing environmental pressures and
restrictions are causing responsible industries and plant operators to look
for alternative methods.

Hard water causes scaling, which is the left-over mineral deposits of
Calcium and magnesium salts , also referred as hardness salts
Scale Formation depend two factors: Temperature & pH. As the
temperature of water in cooling circuit increases, it causes scale formation
on heat transfer surfaces.
As the temperature of water in cooling circuit increases, it causes scale
formation on heat transfer surfaces.
The solubility of hardness salts decreases with the increase in
temperature which results in deposition of salts in precipitate form on
heat transfer surface.
Concerns of water usage in industrial applications
: Scaling 90-92
: Corrosion 4-5 %
SCALE OFF - On Line Scale Prevention System
Water Cooled equipment are required to operate at design
efficiency; careful attention must be paid to the conditioning of both the
raw and re-circulated water.
The polluting techno sphere doses more and more salts into our water
system, the hardness of water keeps increasing. The bicarbonates of Calcium
(Ca) and Magnesium (Mg) salts add to the temporary hardness of water and it
is this parameter of water which requires Scale off. Due to various factors
like change in temperature, pH etc., the carbonates of Ca and Mg salts gets
precipitated and is deposited as scales in the condenser, boilers etc.
Scale and fouling deposits causes poor heat transfer through the exchanger
tubes, reducing efficiency and increasing energy cost. Once a thin film of
scale forms, rate of scaling increases rapidly. Thus to prevent formation of
scale, "Scale off " is used.
WELDON ENGINEERS (INDIA) brings you the state of art technology, "Scale
off" in solving the problem of scale formation in the cooling system.
It is an on line equipment, in the shape of a pipe, made of seamless
stainless steel, with a special core made of alloy fitted inside,
exclusively designed to meet your requirement and can be fitted on the
tapping or the main header of the water feed line without any special
equipment. Size required can be determined by the reference to the chart of
minimum flow rate.
SCALE OFF A online non-chemical water treatment involves no chemicals,
handling disposal or electricity.
SCALE OFF is units are completely self contained. Water passes through a
very special metal alloy in a turbulent state. This electrolytic action
changes the super saturation ratio of water, which physically effect the
structure of suspended particles in the water. After installing SCALE OFF
units your industrial water system will be completely scale-free. Hardness
particles will remain suspended in the water flow instead of forming layers
of scale deposits from these areas. SCALE OFF unit will help prevent new
scale deposits from forming and will also gradually disintegrate any scale
remaining in the system.
A complete line of sizes from 3/8" to 30" in diameter is
available to fit any application. SCALE OFF unit can also easily be fitted
in the existing pipe line without making any alteration in the system. SCALE
OFF unit is built to highest quality standards, completely warranted for
materials, workmanship and long life performance guarantee. SCALE OFF A
online non-chemical water treatment device keeps industrial water systems
scale-free... WHILE SAVING MONEY EVERY DAY OF INDUSTRIAL

Comparison between Scale off and Water Softener
||Composition of Water
||It reduces the pH of water thereby making it more corrosive in
||The water remains neutral only the physical properties changes.
||Heavy monthly expenses in procurement, inventory, storage, handling
and supervision of chemicals and salts to be dozed.
||No Recurring Cost
||Prevention of Scale
||Water softener is designed for a particular hardness level (max 600
||Prevents scale formation and removes existing scales from pipelines

||Special manpower required for regeneration of resins and operation.
||No man power required as SCALE OFF is an online equipment.
||Requires extra manpower for monitoring and dosing of chemicals.
||No man power required as SG is an online equipment
||Needs electrical energy for operation.
||No energy required for operation thus saves the electricity bill.

SCALE OFF possesses many advantages over conventional
water treatment systems, some of which include:-
As SCALE OFF has no moving parts, it requires no replacement of spares or
extra maintenance other than normal plant maintenance.
- Extra Space for the unit is not required
As the equipment is installed on - line of the cooling circuit
Eliminate Recurring Costs of Expensive Chemicals / Resins
SCALE OFF has no recurring costs associated with chemical dosing or water
softening, as no chemicals, regenerative salts or resins are used.
No Energy Consumption for running of the equipment
Unlike conventional water treatment SCALE OFF doesn't require any
power or electrical inputs
Saves in Energy Consumption of the plant
Scale reduces heat transfer efficiency resulting in increased energy
consumption, which can rise by almost 50%. As SCALE OFF is constantly
preventing the deposition of Scale, thereby saving valuable energy cost
No Corrosion Risk
Water softeners necessitate the use of corrosion inhibitors, as the water
tends to be corrosive. SCALE OFF on the other hand has this unique advantage
of preventing scale without increasing the risk of corrosion.
Chemical dosing and water softening system require the use of chemicals,
which are hazardous and cause pollution. Disposal of such hazardous
chemicals in the environment is also a difficult task faced by customers.
Low Payback Period and Saving of Operational Cost
The pricing of SCALE OFF ensures that the user of the systems derives a
payback period of three months to one year. This is made possible by savings
in operating cost as compared to the fixed investment required.
The energy savings, the reliability of your equipment, the durability of
SCALE OFF... add it all, it's a sound investment.
