Curing of BRAWO® resins

BRAWO® 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. BRAWO® SYSTEMS offers reliable heating units, both for
curing acceleration using water or steam, that rapidly pay for themselves.

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
