The ‘ham’ is out of sight of the consumer but remains a
vigilant temperature watchdog.
SAFETY AND NOISE POLLUTION
The CO 2 safety levels, operating parameters, temperature
alarms, power usage, cabinet temperatures are all monitored
and controlled by the Guardian Controls Plant Management
System with visual monitors for management staff and with
remote access by senior staff of Mainstream Refrigeration.
The RH and ambient temperature in the store is also
monitored by the Guardian Controls PMS to keep store
management informed of shopper comfort.
Being close to the Table Bay Hotel, the noise level of the
roof mounted gas coolers at the V&A store was of concern
and was overcome by fitting ebmpapst Axitop and EC variable
speed fans.
The relocation of the food market at the V&A started
during the first quarter of 2019 and was commissioned before
the end of November.
“Replacing 1250kgs of R404A (GWP 3922) with a CO 2 plant
at the V&A and all the energy saving features, has provided
further proof that CO 2 refrigeration is the best solution to
achieve our green policy.” Kuzma concluded. RACA
