The Koolboks Solar Chiller is a fully integrated commercial refrigeration system powered by solar energy. Designed for off-grid and weak-grid markets, it delivers uninterrupted beverage and food cooling while eliminating generator dependence. With embedded IoT and PAYGO financing, it provides scalable, distributed solar cold-chain infrastructure for retailers, distributors, and logistics operators.
Koolboks via Koolenergies provides a "Green Building Energy-as-a-Service" solution for commercial real estate. We deploy 5-30 KVA hybrid inverter systems in office buildings and retail centers to power HVAC and critical loads with solar+battery storage, eliminating diesel dependence. Our zero-capex model converts energy costs to predictable monthly fees, enabling portfolio-wide decarbonization aligned with IFC's GRIP program without upfront investment from property owners.
The Koolboks Solar Ice Maker is a solar-powered ice production system designed for off-grid and unreliable-grid environments. It integrates solar panels, lithium battery storage, and a smart controller to power ice-making equipment without diesel generators. With embedded PAYGO financing, it enables small businesses and fisheries to access reliable ice production without high upfront costs.
The Koolboks Powerfoot is a solar-powered base that converts any AC freezer (Scanfrost, Bruhm, Thermocool, etc.) into a solar unit. Small businesses keep their existing freezer and eliminate power outages and generator costs. Fits 200L-600L sizes, includes battery storage and USB charging. Available via PAYGO financing with daily payments, making solar accessible to market vendors and traders across Africa.
Our electric refrigeration tricycle will be a sustainable and energy-efficient way to transport and store temperature-sensitive goods. It will be equipped with a refrigeration system powered by lithium batteries, which will reduce the need for fossil fuels and minimize carbon emissions. It will be able to maintain temperatures as low as -20°C, making it suitable forapplications such as food and beverage transportation, healthcare, events, construction sites, and disaster relief.
The Koolboks Connected Solar Chiller is an upright see-through refrigerator with integrated batteries. It is designed for storing cold drinks. It offers four basic unique features.
24hrs refrigeration, thanks to the sun.
– Remote Temperature Monitoring
– Image recognition
– Pay-As-You-Go Technology
The chiller has a storage capacity of 440 liters, and measures 705x645x2000mm.
