Curing of BRAWO® resins

BRAWO® epoxy resins can cure at ambient temperature. The addition of heat can significantly reduce the curing time. BRAWO® SYSTEMS offers reliable heating units, for curing acceleration using water, steam or UV/LED light, that rapidly pay for themselves.

Accesoires BRAWO® Hotbox HQ

Hose set (water)

  • 2 x 10 m and 1 x 2 m water hoses with GEKA couplings

BRAWO® Circulation Pump HP 1200 and Basic 840

During warm curing, the BRAWO® HotBox HQ/HotBox L is connected to the inversion drum and warm water is fed into the liner. The necessary circulation between the liner and BRAWO® HotBox HQ/HotBox L is provided by a special pump, which is designed for use with hot water.

Advantages of BRAWO® Circulation Pumps

  • Increased safety during liner installation, thanks to faster and more-uniform distribution of heat
  • High efficiency thanks to short curing time
  • More reliable installation
