Countertop dishwasher debuts

BASF and Heatworks, a US-based tech firm, have partnered to support the further development of the award-winning Tetra countertop dishwasher regarding its cleaning performance. Heatworks is using its patented Ohmic Array Technology to enable the highly anticipated Tetra self-contained countertop dishwasher to wash up to three full place settings with just three liters of water. It's great for apartments, condos and those that have to be mobile. Tetra cleans 50 percent more dishes using 40 percent less water in 55 percent of the time than the leading countertop dishwasher and is set to release in 2021.

“With Tetra, we set out to build a best-in-class dishwasher, and we’re excited to partner with BASF to help us develop a first-of-its-kind self-dosing and tailored cleaning multi-use cartridge system,” said Jerry Callahan, CEO of Heatworks. “As a fully self-contained dishwasher (patent pending), with several specific cycles for washing dishes, stemware, baby bottles, and fruits and vegetables, Tetra does not need any plumbing, which allows it to be deployed anyplace…kitchen, nursery, wine cellar, RV, etc.” Through this partnership the two companies aim to significantly reduce consumers’ waste and maximize Tetra’s efficiency. The goal is to optimize the right amount and type of chemistry based on what the countertop dishwasher is washing: saving water, saving energy and protecting the environment. “Heatworks is using an innovative approach to countertop dishwashers to address the trends of consumers living in smaller flats and with specialty cleaning needs that are not met by traditional undercounter dishwashers,” said Robert Parker, Director, New Business Development & Digital Officer, Care Chemicals at BASF. “BASF is excited to support Heatworks’ development with our leading portfolio of cleaning ingredients.” As part of the project, Heatworks and BASF intend to utilize their complementary capabilities in engineering and chemistry to develop an improved cleaning performance for Tetra’s recyclable cartridge system, enabling a more efficient use of energy, water and chemistry for optimized cleaning. Tetra’s cleaning cartridges will be designed to deliver custom solutions and dosing, dependent on the selected wash cycle, ensuring each cleaning cycle is optimized. Tetra’s cartridges will last for multiple loads and consumers will be able to sign up for a subscription, so they’re always on hand.

Heatworks is reinventing the way the world heats and uses liquids, like water. Rather than coils or traditional heating elements that scale and rust over time, our products use our patented Ohmic Array Technology to leverage water’s natural conductivity to generate heat in the simplest, purest and most efficient way. Liquids are heated endlessly, on demand, to the precise temperature and without loss of energy efficiency over time. Heatworks develops their own products and also licenses their patented technology to companies who want to improve their existing products or develop new products. Heatworks’ goals are to help consumers and companies save money, water, and energy, while improving performance and customer satisfaction. For more information about Heatworks, visit
