Colman has tackled air
distribution requirements for Arla Foods, using a
mix of diffusers, grilles and displacement units
throughout its purpose-built state of the art milk
processing facility near Leeds.
Arla Foods produces some of the UK’s most popular
brands including LURPAK, ANCHOR and CRAVENDALE
PURFILTRE®.
Colman has already supplied a mix of equipment
including REPUS units and stainless steel grilles in
the process, raw milk and pasteurising rooms in
addition to FCU’s for the administration building as
part pf Phase 1.
The latest dairy facility is the product of a £55
million new build that has provided Arla with one of
the most technologically advanced dairies in Europe,
which includes fully computerised traceability from
milk intake to the fillers. The dairy is vast with a
total floor space of 28,000m² and the capacity to
fill over 345 bottles per minute. Each of Stourton’s
16 milk silos can hold 250,000litres.
Kelly Taylor & Associates were the consulting
engineers throughout the design and construction
phases of the project and were instrumental in
specifying the air distribution equipment for this
project. Colman worked closely with Kelly Taylor &
Associates and the sub-contractors N G Bailey in
achieving the final installation. The brief required
the design of an efficient method of producing and
maintaining indoor air quality that addressed
environmental criteria without compromising
performance and functionality. In addition,
aesthetic looks and hygiene were major criteria in
the areas handling raw milk.
The contract worth in excess of £50,000 required a
large number of stainless steel grilles and
diffusers for general areas throughout the facility.
The order included 25 Grade 316 stainless steel
double deflection grilles and 10 specially designed
REPUS stainless steel displacement units to supply
high volumes of conditioned air into high hygiene
areas. The REPUS units were raised from the floor
for easy cleaning.
Eight surface mounted four-way louvre faced
diffusers were included in the specifications along
with 23 Grade 316 stainless steel egg crate grilles
and numerous unlined plenum boxes and unlined
stainless steel plenum boxes. Multiple spigots are
used on the double deflection/egg crate grilles due
to the extremely high air volumes and all volume
control dampers and plenum boxes galvanised except
where stainless steel was required.
Stainless steel grilles provide air distribution
throughout the homogenising, product rooms, and
other raw milk areas to meet hygiene requirements
with standard grilles installed in the office areas.
A displacement ventilation system was specified for
the vast filling and bottling halls where there are
10 lines in operation. In the dairy halls, Colman’s
REPUS VRC quarter round corner panels and RAC half
round/bow shaped panels and a KDC three-way spread
floor-mounted panel delivering up to 5000l/s from a
single panel meet the requirements for higher
airflows.
All the REPUS units are stainless steel with
reinforced fronts and provide a constant airflow
without the risks of draughts.
