Badass! Meet the Mzansi-built, COVID-busting bleach sprayer

THYSSENKRUPP Industrial Solutions South Africa (TKISSA) has designed and manufactured a portable Sodium Hypochlorite disinfection trailer unit for spraying disinfectant in COVID-19 hotspots.

Neville Eve, the company’s GM, Chemical Process Technology, said the World Health Organisation (WHO) suggests Sodium Hypochlorite, commonly known as bleach, for effectively disinfecting surfaces potentially infected with the coronavirus.

As chemicals should be used at the lowest possible effective concentration for safety reasons, the WHO recommends a 0.5% Hypochlorite solution which is achieved through one part bleach (household bleach is commonly available as a 3.5% concentration) to seven parts water to kill the virus. Eve said this dilution is considered as good as the alcohols used in hand sanitisers.

With this in mind, Thyssenkrupp designed the trailer unit for effectively spraying the recommended 0.5% Hypochlorite concentration over large street, pavement and vertical surfaces.

Eve said the company’s experience designing and building machines and equipment for the mining, minerals processing and cement sectors had proved valuable on this project. “By combining these proficiencies together with our local fabrication expertise, we have produced this robust and cost-effective trailer.”

Equipped with a 500-litre, easy-to-refill concentrate tank, the Hypochlorite trailer can spray a 50 000 sqm surface area per day with the replenishment of water only into the diluted liquid tank. The unit is fitted with four spay nozzles allowing four operators to efficiently spray both sides of the street simultaneously.

Weighing 1 600 Kg (gross), the trailer is easily towed by a bakkie or light utility vehicle and is ideal for use by local municipalities, health departments, industrial cleaning companies, etc. Thanks to the smart modular design, multiple units can be manufactured with very short lead times.

Daniel Martinho, HoD: Sales & Proposals at TKISSA), said although the trailer is extremely easy to operate, training is essential for optimal performance and to safeguard users and the public, especially when working with chemicals.

“The training we offer focuses on the tank filling procedure, accurate dilution of the concentrate as well as correct operation of the pump, valves and spray equipment in accordance with the design.”

Martinho said there had already been interest in the concept and that they had received several requests for further information on the trailer. “I can also confirm that a company in the chemical supply sector has expressed interest in purchasing a number of units from us.”

TKISSA CEO Philipp Nellessen said, “Over the past 60 years, customers across the African continent have continued to invest in our equipment, technology and services. Through the development of this Hypochlorite trailer we are able to give back to our partners and to the regions that have has supported us so well.”
