Epoxy resins can cure at ambient temperature. The addition of heat can significantly reduce the curing time. This can be implemented in the form of hot water or steam. BRAWOLINER® offers reliable heating units, both for curing acceleration using water or steam, units that rapidly pay for themselves.

Curing of the BRAWO® Resin with hot water
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.
BRAWO® HotBox advantages
For a fast and uniform distribution of heat
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.
Advantages of the BRAWO® circulation pumps
2 x 10 m and 1 x 2 m water hoses with GEKA couplings
Supplies hot water reliably, efficiently and at three times the usual rate
When it comes to hot-water curing, the BRAWO® HotBox L is a highly efficient heating device. A throughput rate of more than 2.800 litres of water per hour makes the BRAWO® HotBox L the most powerful device of its type for hot-water curing.
The BRAWO® HotBox L has been specially designed for long repair sections and larger diameters.
BRAWO® HotBox L advantages
Full steam rehabilitation
In sewer rehabilitation steam curing has also established itself alongside curing of the resinsoaked liners with warm water. In particular during the rehabilitation of downpipes, where curing with water is only possible with short pipe sections with approx. 4 metres height difference, steam curing has clear advantages.
With the BRAWO® SteamUnit we offers a comparably compact but efficient steam generator. With a heat output of 56 KW the diesel-fired device produces a steam quantity of 50 kg per hour. Thus the curing of longer piping sections in buildings or buried pipes is possible. Thanks to the compact dimensions the steam generator can be accommodated in the BRAWO®Trailer and can if required be positioned directly on site.
Advantages of the BRAWO® SteamUnit
Manual control unit for regulation of curing pressure and curing temperature
Steam hose extension (20 m)
Stam hose set (20 m)
Steam connection adapter
Steam curing for Liner and connection collars
Until now, the rehabilitation of down pipes or pipes with high gradient was possible only in cold curing. BRAWOLINER® offers a mobile solution for accelerating the curing process.
The BRAWO® SteamBox L was developed specifically for in-house rehabilitation. The two electric heaters, each with 1500 W power and the 9 litre boiler, which can be refilled during operation ensures fast and continuous steam generation. In this manner, a large amount of steam can be produced for a longer period. Due to the excellent heat conductivity of the steam, curing of the resin is initiated very quickly. Thanks to the integrated pressure and vacuum control, the BRAWO® SteamBox L is ideal for the installation of connection collars.
Advantages BRAWO® SteamBox L
For installing connection collars
The compact appliance is suitable for installing connection collars by cold curing. With just one hand you can vent the packer or pressurise it.
