Dianorm/Purmo Double x 20" x 48" Radiator

20" x 48" DiaNorm Double DiaNorm has produced millions of radiators made of high quality 1.25 mm FePO1 steel. The finish is epoxy powder coating that is baked at 400°F. The Final Color is white to RAL 9010 that can easily be painted over with any color.  Water connections are not exposed, but located at the bottom. If installed in one-pipe “series loop” installations, diverting valves can be supplied that will reduce installation time and the amount of materials used. A unique flow setter built into the thermostatic valve allows the installer to regulate the water flow through each radiator, eliminating the installation of additional fittings.  An integral thermostatic radiator valve and a standard thermostatic head allow automatic and nonelectric adjustment of the water flow and temperature according to the temperature setting. Since every radiator has its own temperature control, you can decide what individual room temperature you would prefer. The type 22 "double" style radiator has a single panel design, with a depth of 3-3/4", with two rows of convector fins for a higher heat output than the "single" style.  They will project out from surface of the wall to approx. 4-3/4"   We offer the type 22, 20" height radiators in lengths of 16", 24", 36", 48", 64", and 72". PLEASE NOTE -  Because of their steel construction, DiaNorm panel radiators should only be used in closed-loop hydronic heating systems.  Use in open loop systems voids the warranty.  DiaNorm radiators ARE NOT to be exposed to pressures above 145 psi.  The maximum differential pressure across DiaNorm radiators (inlet to outlet connection) is 14.5 psi.  DiaNorm radiators ARE NOT for use in steam heating systems.  The radiator inlet connection (left) and outlet connection (right) SHOULD NOT be reversed.
