Hillphoenix said it has supplied CO₂ Systems for Puerto Rico’s First-Ever All CO₂ Refrigerated Supermarket.

The installation of the CO₂ system at the supermarket, called Ralph’s, was a collaborative effort involving the expertise of Hillphoenix and the dealer, Triple S International, the company said.

The project included the installation of a CO₂ system, display cases and a PowerWall power distribution and control system, making Ralph’s the first food retailer in Puerto Rico to implement a CO₂ system on the island.

This store is equipped with two mechanical CO₂ systems. One rack is dedicated to medium-temperature capacity, while the other serves both low-temperature and medium-temperature needs.

Hillphoenix said it provided comprehensive training and engineering support beforehand during equipment selection and afterward during the startup and commissioning of the project in collaboration with Ralph’s.

“Bringing new technology to the island was a visionary goal for Jose Soto, President of Ralph’s Supermercado y Mayorista. His aim was to find a sustainable solution to combat refrigeration challenges in this region, including high temperatures, high humidity and an unstable electrical system that can cause power outages and brownouts,” said Hillphoenix in a statement.

Built inside a decommissioned K-Mart in San Juan, Puerto Rico, the new Ralph’s location opened its doors in December 2024.
