26 3 2012 COOLMANT CLM Subject to technical modifications System description 1 General COOLMANT is the registered trade name for a rigid pipe system from Brugg Pipe Systems with carrier pipes made of polyethylene This pipe system is especially suitable for use in local and district cooling networks in industrial and with restrictions also for combined heat pump systems cooling and heating The COOLMANT district cooling pipe has a carrier pipe produced from high density polyethylene PE100 as per standard EN 12162 The polyethylene pressure pipes are the standard for drinking water and waste water systems and also for the gas supply sector The pipes are joined by means of standard screwed connectors mechanical pipe couplings with normal commercial electro fu sion fittings or by means of butt fusion welding technology The insulation is made of fine pore CFC free rigid polyurethane foam and together with the me dium pipe it forms a compact composite system with excellent insulation properties The outer casing meets the requirements for plastic casing pipes as per EN 253 ensuring that the district cooling pipe is reliably protected against mechanical influences and the possibility that water could penetrate the system The pipes can therefore be installed at outdoor temperatures down to 0 C In combination with the flexible COOLFLEX district cooling system these features make it possible to implement applications involving widely varying requirements imposed by the terrain so the installation outlay is substantially reduced 2 Range of applications Max continuous operating temperature TBmax 20 to 40 C Max permitted operating pressure p max 16 bar warm water application with limited lifetime and operating pressure as per DIN 8074 2 100
