The HELIOS line by ROXBOX offers a range of solar-powered refrigerators and freezers designed for rapid and easy deployment. Each mobile refrigerator and freezer is 100% solar-powered with an integrated battery and energy management system requiring no fuel, generator, or grid connection, therefore giving you the reassurance of knowing you have an uninterrupted power supply (UPS). Our solar-powered refrigerators and freezers offer a greener, cleaner, and quieter mobile chilling solution with no ongoing operating costs vs. antiquated, expensive, and dirty diesel-powered alternatives.

Each solar mobile refrigerator and freezer unit is transportable (by road, rail, and/or sea), securable, and can be fully customized to your specific needs, including hybrid and microgrid-compatible solutions. Remote operation and monitoring are also available, right down to alerts of a door being left open, temperature monitoring, carbon savings, etc. Real-time performance monitoring and analytics are also available, providing reporting up the lines of your organization to give insights into carbon emissions, cost savings, and uptime.

Our HELIOS Refrigerators and Freezers can be transported anywhere in the world via road, rail, and sea. Once on-site, the solar panels can be deployed by a single person within 15 mins. There are no special tools or training required to operate, set up, and/or tear down the unit. Each HELIOS Refrigerator unit features a broad operating temperature range of +35°F to +55°F (+2°C to +15°C), making it an ideal option for warmer climates. Energy usage patterns of your solar-powered refrigerator/freezer are logged and analyzed 24/7, giving your team the ability to report your savings and contributions up the line in real-time.

Energy consumption is considered the largest source of human-caused greenhouse gas production and the cold chain is the 3rd largest consumer of power in the world. Therefore, choosing an industrial solar-powered refrigerator or freezer means you are immediately reducing your carbon emissions and making a significant reduction to your environmental footprint.

There are significant cost savings by choosing our HELIOS refrigerators and freezers over a diesel alternative, and an increasing number of organizations are seeking more environmentally friendly powered solutions for their cold chain needs.

Our HELIOS Refrigerator & Freezer options are designed to be used across a range of industries including mining, logistics, defense, government, agriculture, aquaculture, and commercial organizations. 

They can also be used by first responders seeking low-maintenance, emergency preservation solutions, aid and development agencies looking for long-term, cost-effective cold chain options that can be rapidly deployed, as well as event organizers seeking a practical, economical, and environmentally friendly refrigeration alternative to traditional grid power.
