The BRAWO® HotBox is a diesel-powered continuous heater specially designed for domestic sewer renovation. Thanks to the high heating output, up to 1000 litres of water can be heated per hour. The mobile unit can be easily transported and can be operated outdoors close to the renovation site.
During the hot cure process, the BRAWO® HotBox is connected to the inversion drum and warm water is then passed into the liner. Once the curing water is at the correct temperature a special pump, designed for use with hot water, is used to re-circulate the water through the liner and the circulation pump.
