Enabling a Greener Cold Chain — Without Replacing Your Fleet
Practical Innovation for a Greener Cold Chain
Renewable Innovations & Solutions Ltd (RIS) exists to help refrigerated transport operators transition to cleaner, smarter energy — without the disruption and cost of replacing existing fleets.
Our engineering team specialises in bolt-on renewable systems designed specifically for refrigerated trailers. Our flagship solution, GreenChill Systems, delivers zero-emission cooling powered by solar energy and on-board batteries, while intelligently retaining the existing diesel engine as a backup. This ensures uninterrupted performance and temperature control, no matter the route or conditions.
Because GreenChill Systems are retrofit-ready, they can be installed on both new and existing trailers — allowing operators to modernise their fleet without needing to purchase new vehicles. Built for quick installation with minimal downtime, GreenChill Systems keep fleets on the road and earning during the upgrade process.
Integrated telematics and real-time monitoring give operators full visibility and control over energy use, battery status, and refrigeration operation across the entire fleet.
Our optional Digital Power Management System takes this one step further, enabling bi-directional charging and depot integration. This turns trailers into mobile energy storage units capable of returning power to depots during peak demand — reducing electricity costs, supporting grid stability, and lowering carbon impact.
From remote fridge control to smart charging and seamless energy integration, RIS empowers cold chain operators to reduce fuel costs, meet sustainability targets, and stay ahead of regulatory requirements — all with technology designed to work with the fleet they already have.
