Waitrose has developed and installed
a hydrocarbon-based refrigeration
system that is free of hydrofluorocarbons,
a source of carbon emissions.

Helping Waitrose towards its
green goals is Next Control Systems,
which provides round-the-clock
remote monitoring services to
monitor refrigerated cabinets and
storage areas in the company’s shops.

Next also provides building and
energy management services,
managing and controlling heating
and lighting. Savings of up to 14%
on power sources have been delivered
with average pay-back time between
eight and nine months. Systems have
been upgraded to full IP networked
and wireless systems.

The company is also controlling
and remotely monitoring the new
refrigeration system, which involves
chilled water being moved round the
cabinets to remove excess heat
generated by the refrigeration.
