Distributors; Distributors For 2 Heating Circuits - meibes BigFixLock Documentation Technique Mise En Service

5. Distributors

The distributors consist of two stacked chambers with thermal separation of the supply and return lines. The boiler circuit is both connec-
table on the left and right hand side. All connections are prepared so that BigFixLock clamps can be used. The top outlets for connecting
the heating circuits are designed with BigFixLock groove in the nominal width DN 50 (Ø 60.3 mm). All distributors are painted, pressure
tested, fully insulated and supplied with two feet*. Furthermore, 2 couplings and 2 end caps are supplied with a 1/2" drill hole as well as
insulation for the clamps. The holes are sealed with plugs. Alternatively, a KFE-cock can be screwed on for emptying. The distributor sys-
tem consists of elements for two or three heating circuits, which can be combined as desired, depending on the axis-centre distance.
