Fox’s Biscuits in Preston has installed
an EasiHeat Engineered System from
Spirax Sarco. The factory found its
system of two, 1000L calorifiers
couldn’t keep up with demand from
the site’s cleaning operations,
especially at weekends.

Now, the EasiHeat system uses a
steam-to-hot water plate heat
exchanger to provide domestic hot
water on demand. The compact
system was supplied skid-mounted
ready to connect to the site’s utilities.

Spirax Sarco says this approach is
typically more
energy efficient than
systems relying on
stored hot water
because it avoids
significant heat loss.

Fox’s can use its
calorifiers as
buffers. The
system is set up
so that EasiHeat
feeds the factory’s taps directly on
demand and can maintain the
temperature in the buffer vessels
when it would otherwise be idle.
