backup is vital; the risk is simply too high,”
says Baring Richardson. They even have a
backup generator that can run one of the
chillers in case of a power cut.
The chillers both run on R134a refrigerant
and provide 680kW of cooling each.
The WF model is a standard water-cooled
screw chiller that can only operate with a
maximum condensing water temperature
of 50°C. While the HWF model is a high-
temperature water-cooled chiller that can
operate with condensing water up to 60°C;
therefore, they can be used to produce hot
water for domestic applications.
WATER MATTERS
The farm uses minimal water for farming
and none of it leaves the property. Every
drop is getting used, sometimes twice (or
even three times). They are very aware of
