Balmoral GroupBalmoral Group is a privately owned
company headquartered in Aberdeen,
UK. Employing over 400 people the
company has been providing solutions
to the building, chemical, energy,
engineering, marine, and plastics
sectors since 1980.
The Group comprises three distinct
business units: Balmoral Advanced
Composites; Balmoral Marine,
Balmoral Tanks, and wholly owned
international subsidiaries: Balmoral
Norge AS in Stavanger and
Kristiansund, Norway, and Balmoral
Marine Inc and Balmoral Tanks Inc in
Houston, USA.
These business units and overseas
operations function autonomously
under the auspices of their respective
managing directors while remaining
under the overall commercial and
financial control of the Group's main
board of directors.
The enterprise is built upon research,
development and technical innovation.
It is this commitment to progress that
has helped the group achieve its
status as a market leader in its
chosen sectors.
The strategy is well recognised by
Balmoral's client base: independent
surveys link attributes such as
innovation, technology, engineering
proficiency and proactiveness with
Balmoral. The Balmoral name has
become a brand in its own right,
synonymous with product
development, technical excellence and
manufacturing efficiency.
Since its formation in 1993, Balmoral
Tanks has become the world's largest
single source designer and
manufacturer of liquid storage and
treatment products. Covering the
chemical, environmental, water,
wastewater and fuel sectors, the
enterprise designs and manufactures
rotationally moulded seamless tanks,
hot press moulded GRP and steel
sectional water tanks, air pollution
control systems, cabinets and
housings.
Hot press moulded GRP sectional
tanks, in a variety of panel sizes, are
produced and used to store potable
and non-potable water on a global
basis. These tank panels are designed
for use in varying climatic conditions
and can be provided with integrated
insulation.
Hot pressed steel tanks are
designed and manufactured by
Balmoral-owned Horseley Bridge
Tanks. Established in 1880, it is the
oldest tank manufacturing company in
the world and the pioneer of bolted
sectional water tanks.
Rotationally moulded tanks
ranging from capacities of 500 to
75,000 litres are currently produced,
and it is this flexibility and
comprehensive product range that
gives Balmoral Tanks its competitive
advantage.
The vast majority of Balmoral Tanks�
products are accredited and approved
by numerous agencies: BBA; IAB; IP;
LPCB; OFTEC and WRAS to name but
a few. In gaining these accreditations
Balmoral has raised the integrity and
standards of the tank industry around
the world.
Synonymous with product development,
technical excellence and manufacturing
efficiency, innovation lies at the heart of
Balmoral Group. It drives everything
the Group does. Huge investments have
been made in research and
development over the years and the
company benefits from its own
laboratory and testing facilities.
The very latest in computer aided
design (CAD) and finite element
analysis (FEA) software is available to
the company's engineering design team
to complement the 21st century
manufacturing plant on the factory
floor. This investment has propelled
Balmoral to the peak of the hot press
and rotational moulding industries.
Design
The design of each sectional tank panel
is modelled using FEA software. This
allows fine detail to be thoroughly
investigated and improved before
proceeding to mouldmaking and
production.
Materials
All materials used in the production and
assembly of Balmoral GRP tanks are
rigorously tested for potable water
compatibility. This includes long term
material performance and mechanical
properties, non-metallic components,
adhesives, etc. Combined, these
analyses form the basis of the
company�s extensive QC procedures.
Engineering innovationManufacturing process
Balmoral sectional tank panels are hot
press moulded in glass reinforced
plastics (GRP) using isophthalic
unsaturated polyester resins and
electrical glassfibre reinforcement.
The panels are moulded at
temperatures up to 150°C under strict
quality control disciplines. The process
results in strong, consistent panels
which are fully cured, dimensionally
accurate with sharply defined profiles
and smooth surfaces on both faces.
Drilling and finishing of the panels is
undertaken in a purpose built
controlled area, where high technology
automated drilling equipment is used
to complete production to exacting
tolerance levels.

QA Balmoral Group is certified to BS EN ISO 9001:2000
Thermal insulation
Balmoral Sectional Tanks uses
expanded polystyrene (EPS)
materials in its thermally insulated
panels. This is made using a pentane
expansion agent which is CFC and
HCFC free and can be recycled by
melting down and reforming.
UV stabilised skincovering the maximum
surface area of panel
HCFC free insulation
The Balmoral range of sectional GRP
tanks may be specified as either
externally flanged base (EFB) or
internally flanged base (IFB). This
allows the use of either flat continuous
foundations, close centre beams, pier
walls or bearer beams depending upon
the type of base required. The internally
built tank (IBT) to be supported as
standard on an IFB foundation.
The EFB specification is fully self
draining allowing ease of maintenance
and cleaning.
� Flexibility of panel sizes allows
connections to be agreed on site to
suit actual tank location
� Modular design provides ease of
transport and flexibility of assembly
on either a prepared flat and level
concrete foundation, support walls
or bearer beams
� Panels are rigidly supported by a
combination of stainless steel tie
rods internally and galvanised box
sections externally
� Installation is carried out by
Balmoral approved installers, fully
trained to provide total unified
responsibility

Balmoral M100 and M100-B30 sectional tanks
are Loss Prevention Certification Board (LPCB)
approved for fire fighting sprinkler systems.
� Sprinkler systems must comply with
BS 5306 Part 2: 1990
� A type AB air gap is required unless
connected to a dedicated water supply
� Internal ladders should be stainless steel.
External ladders compliant with BS 4211
� Water level indication is required on sprinkler
tanks
� The water in sprinkler tanks tends to be
inactive for long periods of time. Immersion
heaters or other means of preventing
freezing may be required
� In the event of a fire, large quantities of
continuous flow are required. If a vortex
inhibitor is fitted, the volume of water that
can be drawn from the tank is increased
without the inclusion of air or a reduction
in the flow rate. There are two main types
of vortex inhibitor: positive head and
suction lift
