Perutnina Ptuj

SITUATION BEFORE THE CONTRACT AND CLIENT REQUIREMENTS

Perutnina Ptuj’s meat packaging plant in Zalog requires several cooling
chambers set at different temperatures for its production. The original
cooling processes used ammonia compressors for all chambers, providing
temperatures ranging from -20°C to 0°C.

Some of the older compressors are up to 40 years old and have an
exceedinglypoor energy efficiencyratio.

GGE SOLUTION

GGE developed a parallel solution for the 0°C chambers that represent
around 50% of the plant’s total cooling space.

An air-to-water liquid outdoor chiller using propylene-glycol at -6/0°C as
the cooling substance was installed.

With a cooling capacity of 760 kW, the energy efficiency ratio is twice as
high as for the existing technology used at the Zalog plant. Under
Eurovent conditions, this impressive chiller weighing 8 tons could have a
capacity as strong as 1300 kW.

RESULTS

  • Plant has the required cooling capacity to operate fully.
  • Plant has contingency systems in place.
