Water Jetting Solutions for Heat exchangers, Economisers and Boilers

Is your Heat Exchanger efficiency on
the decline?
Without a regular deep clean, fouling and debris will reduce heat exchanger
efficiency and can, if left unchecked, cause industrial equipment and
processes to fail.
Heat exchangers and condenser tube bundles are fragile, immobile, and expensive.
Shut-downs can be caused by blocked or even partially fouled tubes and these can
cost hundreds of thousands of pounds — many times the cost of performing even the
most complex cleaning procedures. When performed correctly, however, heat exchanger
cleaning will improve performance and save money.

UHP Water Jetting Methods for Cleaning Boilers, Economisers and Heat
Exchangers
At RGL, we know ultra-high-pressure water jetting should be one of the first choices for every heat
exchanger cleaning program because it is effective and environmentally friendly. Using nothing
but water, it is possible to successfully remove deposits and scale from heat exchangers, tube
bundles and surrounding systems, without damaging the delicate tube materials.

The systems RGL deploy can tackle vertical, horizontal, straight or
U-bend bundles with tubes as small as 10mm in diameter.
High-pressure water is a safe and controlled cleaning method that
won’t damage the wall of the tube. It also cleans the tube back to
its original surface and restores both flow capacity and heat transfer to
ensure optimum efficiency is regained.
Our jetting tools easily negotiate
curves to provide a thorough
clean
Using water reduces the need for specialist disposal of potentially harmful solvents and detergents.
This also will help to lower the costs of cleaning and maintenance by negating the need for hazardous chemical
disposal services.

Case Study - Muntons Maltings - Stowmarket
Over the past 18 months, Muntons Brewery in Stowmarket had been suffering from the declining efficiency of
their condenser units. This meant that their Malt Extract batches were no longer meeting their high standards.
Our goal was to restore the efficiency levels of the Heat Exchanger/Condensers, this would result in
production operating with minimum downtime.
On this occasion, RGL assessed the Muntons situation and devised a way of deploying variously
sized and rotating jet nozzles to focus the power of UHP water (2800bar) on the contaminated
areas - cleaning it back to original specification.
The condenser face was cleaned manually using hand lances fitted with a rotary nozzle
which, when combined with Ultra-High-Pressure water provides an ideal and safe way of
removing the toughest deposits.
The inside surfaces of the tubes were cleaned using a similar technique but with
nozzles designed to unblock and polish. These heads are extremely effective at
removing thin, hard scale, carbons, coke, and polymers and leave a clean,
undamaged surface.
Using UHP instead of traditional HP water jetting resulted in the use of
significantly less water (approx. 50% less) which facilitated simplified
containment, treatment and disposal.
What the customer said - Graeme Flounders Engineering Team Leader at Muntons Plc.
“The production department had not been able to achieve
the targets required, this was causing a significant problem
as we maintain very high standards which includes
providing our customers on time in full. The process
Leaders informed Engineering that following RGLs visit
to Muntons the Condenser Clean has increased the
efficiency of the equipment to a level not seen for
many years”.
Precision Industrial Water Jetting Solutions - | Cutting | Cleaning | Decommissioning | Surface Preparation

Over the last four decades
the company has evolved
to become the one of
the leading authorities
on UHP water jetting -
supporting industrial and
civil engineering industries
with cutting, cleaning,
surface preparation and
hydrodemolition solutions.
Abrasive Water Jet Cutting
An abrasive water jet will cut through hard materials
such as steel without heat or sparks. This means it
is safe to use for cutting applications in hazardous
atmospheres where there is a risk of fire or explosion.
Surface Preparation of Steel
The most common cause of premature coating failure
on steel structures – such as bridges, storage tanks and
vessels – is poor surface preparation.
Monopile Cutting
Our remote-control internal pile cutting system enables
us to cut off piles below ground or seabed level.
Tank, Vessel and Column Cleaning
Industrial Tank cleaning by water jet is one of the most
efficient forms of restoring production efficiency. The
problems caused by build-up of contamination on
vessel sides, agitator shafts and blade surfaces can be
a major one
Pipeline Cleaning & Blockage Removal
It is well known that drains and pipes have a tendency
to “close up” due to the build-up of scale and sludge
which restricts flow leading to a slower process speed.
Industrial Boiler and Economiser Cleaning
It is well known that when a boiler and/or economiser
becomes choked it’s efficiency is greatly reduced. RGL
provide an efficient on-site cleaning service to restore
the efficiency of your Boiler.
Heat Exchanger & Tube Bundle Cleaning
Ultra-high-pressure water jetting is a highly effective,
non-destructive method of cleaning Shell and Tube
Heat Exchangers, Finfan Heat Exchangers and
Condenser Tube Bundles that have become blocked
or fouled.
Precision Concrete Removal
RGL have pioneered the introduction of “Ultra High
Pressure” water jetting into the hydrodemolition industry
and continue to build on our solid reputation that has
been developed over the past 35 years.
Surface Preparation/Scabbling of
Concrete
UHP Water Jetting is typically used on large areas of
concrete to scabble or prepare the surface for over
coating. Wherever possible, we use our Limpet blast
head which incorporates powerful vacuum recovery of
both wastewater and debris
Scabbling and Laitance removal
Concrete scabbling is a safe and efficient method
of exposing the aggregate in concrete, creating a
roughened surface on to which, coatings, sealants,
adhesives or further concrete may be applied.
Refractory Lining Removal
Our hydrodemolition technique can be used for
removing refractory from boiler water walls, leaving the
delicate tubes undamaged and perfectly clean ready
for re-application of new refractory material
