KOKO Networks in East Africa have created a scalable solution to the dirty fuels problem
KOKO’s fuel distribution model, incorporating Titan’s NSF-Approved 800 series flowmeters, uses Bioethanol as an ultra-clean, cheap and safe alternative to the more traditional cooking fuels of charcoal and paraffin.
Designed and built by KOKO Networks (Nairobi), the KOKO Point vending machine dispenses ethanol and is part of an elegant solution to the widespread problem in African cities: how to get cheap, safe fuel into homes to use for cooking. Across Africa, where electricity connections are patchy and mains gas non-existent, cooking fuel has been dominated by charcoal and paraffin, both of which give off fumes and soot that contribute to the premature deaths of thousands of people a year. Made from corn or sugar cane, ethanol is much safer but can be hard to package and transport.
As a result of our joint development, at the heart of each KOKO Point Ethanol vending machine is a precision Pelton wheel turbine flowmeter
KOKO Networks has installed over 2,000 KOKO point vending machines to date in corner stores across Kenya, including Mombasa and Nairobi. Drawn by the alure of this safe, clean cooking fuel, customers dispense the fuel into reusable KOKO fuel bottles and once at home, they connect the bottles to KOKO-designed twin-hob stoves, which have an airlock to limit fumes and prevent spillage.
Neil Hannay, Senior R&D Engineer at Titan Enterprises commented: "We were approached by KOKO Networks to work with them on this life changing development for African families. KOKO Networks required a highly reliable and inexpensive flow meter capable of precisely dispensing batches of Ethanol cooking fuel. As a result of our joint development, at the heart of each KOKO Point Ethanol vending machine is a precision Pelton wheel turbine flowmeter that rotates freely on robust sapphire bearings, combining materials and technology to ensure a long-life product with reliable operation throughout.”
Titan’s NSF-approved 800 series turbine flow meters are ideally suited for applications where both food hygiene and precision flow measurement are required. These turbine flowmeters are designed for accurate batch delivery systems, such as those used in KOKO’s dispensing vending machines installed throughout Kenya, delivering clean bioethanol cooking fuel into African homes.
