Product description Brand name and product description

Originally designed by Institutional Energy Solutions (IES) (previously InStove) the water pasteurizer is a gravity-fed unit that kills microorganisms by heating water to the pasteurization temperature of 71 ºC and cooling it back down to safe drinking temperature. The system is housed in a 60 L pot and is designed to work with 60 L and 100 L cookstoves, but could potentially be used with other heat sources. The flow rate depends on the water inlet pressure, ranging from 3-8 L/min. Interview with designer
