INDUSTRIAL REFRIGERATION I FOOD PRODUCTION
Heat transfer fluid, Greenway® Neo, saves
energy: a demonstration
RCI obtains immediate and impressive savings for Comerándalus (ArteOliva), thanks to the high specific heat of Climalife’s heat transfer fluid.
Five years ago, Manuel Conde created the Industrial Refrigeration division of RCIndustrial (RCI), a Spanish engineering firm, able to respond to the needs of
customers in this field.
RCI had already redesigned the installations at Comerándalus to achieve optimal performance during the cooking, packaging and chilled storage of traditional Spanish sauces and soup. Products such as gazpacho, salmorejo, aioli and tumaca, and even custom made products which are exported to 82 countries.
A challenge: new temperature values for a new production process
A new challenge arose: to prepare an unpasteur- ised organic gazpacho, for the “Bio ArteOliva” brand, packaged and refrigerated for a short shelf life.
The installation’s monopropylene glycol could not bring the temperature of the soup down from 55°C to 5°C.
At best, it reached 15°C, which meant that the gazpacho had to go through the cooling circuit several times.
“The heat transfer fluid remained too warm and the heat exchange process did not cool the product enough to let us package it,” explains Manuel Conde. Antonio Muñoz, Production Director at Comerándalus (ArteOliva), adds: “The days were getting longer and longer, and a lot of working hours were lost.”
Manuel Conde then designed and built a new tank specially for ArteOliva, which was four times larger than the previous one. This tank is equipped with an ingenious circulation man- agement system “that brings up warm glycol and pushes down cold glycol thanks to a set of valves. We thereby struck a balance between the machines and the production requirements but we could not go any further as the chiller, a
Keyter WT 3485 R compact with a 300KW (net) air condenser, would have stopped working”.

Greenway Neo, an exceptional fluid
It was at this point that Climalife proposed Greenway Neo®, which would meet the needs of RCI’s project: “As we were about to use the conventional, petroleum-based fluid, monopro- pylene glycol (MPG), the Climalife salesperson responsible for the south of Spain and Portugal, José Manuel Arcos, told me about Greenway® Neo. He showed me the product’s technical characteristics and I realised that Climalife had an exceptional heat transfer fluid,” the installer explains.
RCIndustrial and Comerándalus filled the new tank with Greenway® Neo, confident that they would not have to interrupt the production of other sauces and that they could count on a small additional reservoir containing 5,000 litres of MPG.
