INDUSTRIAL REFRIGERATION I FOOD PRODUCTION

Everything was ready in under three days. Manuel Conde explains: “On the first day, we poured 8,000 litres of Greenway® Neo, with a concentration of 35%, into the 20,000-litre tank and brought the temperature down to -9°C.”
Passed the test with flying colours
“On the second day, we carried out an extreme test: we increased the water temperature to 98°C (instead of the gazpacho to 55°C) and noticed that the Greenway® Neo fluid came back 10°C colder than the previous MPG-based heat transfer fluid in the circuit.”
On the third day, Comerándalus started production of the new unpasteurised organic gazpacho. Thanks to the thermal conductivity of Greenway® Neo, we managed to bring the temperature down from 55°C to the required 5°C in no more than 10 minutes. RCIndustrial Refrigeration Director and Comerándalus management described the result as “impressive”.
“We still had to adjust the output temperature of the heat transfer fluid as the carton would not close because the gazpacho was so cold when it was filled. The liquid cooler now operates at less than half its capacity,” Manuel Conde concludes.
Savings at every level
This heat transfer fluid provides quantifiable savings both in terms of the energy bill and the time spent by the Comerándalus teams, because the refrigeration production process is now shorter.
It is also worth noting that the principles of Greenway® Neo are consistent with the ethical and environ- mental commitments championed by ArteOliva and
RCIndustrial. Greenway® Neo is not a petroleum-based fluid, like traditional glycols. It is plant-based and the anti-corrosion technology used in its formulation does not contain any toxic elements. It is also bacteriostatic and to ensure an even more eco-friendly footprint, it biodegrades in less than one month.
The whole range of sauces and soup made by Com- erándalus is now produced with Greenway® Neo. Manuel Conde concludes: “The results exceeded our expectations and those of the production team.
The characteristics of Greenway® Neo are true: we have seen that it is far better than any other glycol. Without any doubt, it is the best heat transfer fluid currently on the market.”
