Really Useful Products, is
enjoying a 10% increase in
productivity due to a series of
solutions from IsoCool
which have cut manufacturing
time. In addition, an IsoFC
energy saving device, which
IsoCool retrofitted to the
plant’s existing system, is set
to reduce cooling costs by
more than 50% (more than
£18,500 every year).

The company’s mould
circuit used to be cooled by a
single water chiller with a
316kW cooling capacity, plus
an air blast cooler for the
hydraulic oil cooling circuit.

When an issue with flow
capacity arose, as well as a
suspected fault, IsoCool
provided a solution.

Nigel Hallett, MD, says: “We
installed a weir tank and
separate chiller and process
pump sets, with VSDs on the
pumps. Due to the weir tank
design, air contamination is
no longer a problem as the
tank self-vents the return
water from the process.”
IsoCool also improved the
mould cooling system,
installing large process
pumps. This has reduced cycle
times on the injection
moulding process.Modular
design means another chiller
can be added in the future.
