Keeping cool: innovative technology slashes energy use and costs of retail refrigeration.

Ice-cream retailer Helados Popsy has over 220 outlets across Colombia, and refrigeration currently accounts for over 70 percent of its energy costs. It is partnering with Spain’s BiofreshTech to field test an integrated technology that needs only a small initial charge to cool or heat any space to the desired temperature for up to six days, operating autonomously, without the ongoing need for electricity, and with real-time control.
