aquatherm ISOPRE-INSULATED PIPE SYSTEM FOR DISTRICT HEATINGAll mediums pipes of the aquatherm ISO pipe system in the dimensions32 – 125 mm are connected with fittings by socketwelding and in the dimensions 160 – 355 mm by butt-weldingaccording to the plastic-welding regulations DVS 2207/08. Thepipe ends of the mediums pipes are not insulated on a length of250 mm to make a proper and professional conjunction. For theinsulation of all connections please use the aquatherm ISO socketsconsisting of four PUR-rigid foam elements correspondingto the dimension, two melting adhesive strips, one casing shrinkfilm and one shrink sleeve.Mediumpipeaquatherm ISO is available with different medium-pipes. All medium-pipesare made of fusiolen (PP-R), mechanically stabilizedby a fiber mixture in the middle material layer.Insulationaquatherm ISO pipes and fittings are insulated with polyurethanerigid foam (PUR), tested according to EN253. In the productionline discontinuously foamed between medium and casingpipe, a high-class insulation with outstanding thermal conductivityλPUR=0,0275 W/mK and low specific weight is formed byan exothermal chemical reaction.All aquatherm ISO components are generally produced with a100% Freon-free an thus environmentally-friendly Cyclopentanedriven PUR-foam. That means huge insulation characteristicsand at the same time minimal possible ozone depletion potential(ODP=0) and greenhouse potential values (GWP=0,001).Casing pipeFusiotherm ® faser-composite pipe SDR 7,4Max. operating pressure:Max. operating temperature:Colour:climatherm faser-composite pipe SDR 11Max. operating pressure:Max. operating temperature:Colour:climatherm OT-faser-composite pipe SDR 1120 bars70° Cgreen with4 moss-green stripes10 bars80° Cblue with4 wide green stripesThe casing pipe of the aquatherm ISO is made of the approvedPE with a smooth surface. Polyethylene is a seamless extrudedimpact resistant and break-proof viscoplastic high density polyethylene,applicable up to -50° C. General quality requirementsare according to DIN 8075. Treated with Corona for best adhesionat the PUR-rigid foam, acc. to EN 253. Dimensions resp. wallthickness at least acc. to EN 253, thermal conductivityλPE80 = 0,38 W/mK.Polyethylene is highly resistant against climatic influence andUV-rays as well as against nearly all chemical compounds in thesoil. Thus in all national and international regulations PE is recommendedas the only suitable material for the laying directlyin the soil.aquatherm ISOMax. operating pressure:Max. operating temperature:Colour:10 bars80° Cblue with 4 grey stripesField of application: see operating pressure tables.The manufacturer´s operating instructions are valid.
