ADX™ Technology Used In Costa Rica's First Low Charge Ammonia System


Costa Rica, March 18th, 2021 - The first low charge ammonia and direct expansion installation was completed in Costa Rica in the Stratum Coca-Cola project. Engineering Firm Refrigeracion Y Soluciones De Frio was tasked to develop the refrigeration system of the 43,000 Square Meter Coca Cola Concentrates Plant. Colmac Coil ADX™ low charge ammonia technology was chosen by Refrigeracion Y Soluciones De Frio to help Coca-Cola accomplish its environmental, energy and safety goals and to introduce the safe and efficient direct expansion technology to Costa Rica.     

"We had the honor of being chosen to develop the entire refrigeration part of this project " Said Engineer Lisandro Salas Mora, Founder & CEO of Refrigeracion Y Soluciones De Frio    "This is a really important project. Not only for the brand of Coca-Cola, but for the country of Costa Rica."

 The project was originally designed by another professional group as a recirculated system with ammonia.

"After winning the job, there was questioning of the ammonia charge, then we were asked to redesign the system." Said Engineer Salas "This was the perfect opportunity to redesign the project with a new technology that has not been applied yet in Costa Rica" 

The redesign of the refrigeration system, including Colmac Coil's ADX™ technology delivered:

  • Increased energy efficiency of the refrigeration system.  
  • A natural refrigerant that does not contribute to ozone depletion and global warming.
  • A system developed under IIAR standards and INTECO standards in Costa Rica, Montreal Agreement and Neutrality Carbon Country Program

"The truth is that this achievement is not mine, it is an achievement of the whole company," said Engineer Salas
