Chiller chosen for biscuit role
July 1st 2009 Chilled water provided by a Daikin
EWAQ130 air cooled R410A chiller
supplied by Daikin Airconditioning
UK, is playing a significant role in
the production of biscuits at the
United Biscuits subsidiary McVities'
'flagship'Harlesden factory.
Joining other Daikin glycol chillers
at the site, the new 130kW unit cools
28t loads of sunflower oil, delivered
in tankers, at a temperature of 30°C.
Oil is transferred to a holding tank
and pumped through three 6m long
hygienic shell and tube heat
exchangers mounted in series to be
cooled to 25°C over a 2h period.
During the blast cool mode the
chiller supplies glycol at 5°C.
The chiller is then reset to supply
water at 10°C during the part load
phase to improve efficiency and
reduce running costs. More articles from Daikin Airconditioning UK Ltd: |
