The Meibes concept for the specialist: Easier. Quicker. More successful. Easier Complete pre-assembled modules ensure that you have everything you need exactly where you need it, on the spot, at the right time and at the right quality. Quicker Time is money, particularly in our business. Meibes systems are rapid installation designs, completely pre-assembled and sealed. All connections are flat-sealing; simply tighten the union nut, and the job s done. This cuts down on assembly time, makes every installation secure and reliable and prevents any unpleasant surprises if it comes to recalculation. More successful Rapid installation technology makes sure you stay one step ahead with every quotation you make. Shorter installation times mean less labour costs, and that means less entrepreneurial risk and lower prices. Meibes are the pioneers in rapid installation techniques, and for more than 40 years Meibes products have been the key to suc cess in the profession. And to make sure you maintain your lead tomorrow as well as today, Meibes keep developing new products and new ideas all the time. The energy label Leading manufacturers of heating pumps have committed themselves to a voluntary and uniform system of energy consumption identification. With the help of energy consumption data, the energy label makes a comparison between individual pumps easy. The label is subdivided into energy coefficient classes from A to G, with Class A standing for particularly economical and G signifying high energy consumption.

Constant heat regulation set Constant heat regulation set/edition 7 3-way T-mixer with fully adjustable bypass The constant heat regulation set is a heating circuit with a mixer for under floor heating. The flow temperature can be adjusted at the 3-way T-mixer. Water from the return is mixed into the flow through the adjustable bypass, and the quantity of water circulating in the heating circuit is increased as a result. A surface thermostat allows for a temperature delimitation safeguard to be implemented. In the event of the flow temperature being exceeded the pump is switched off. Constant temperature control set, regulated by thermostat Complete with circulating pump (EL 180 mm) with 2 m connection cable, two 3-way ball valves (one with manually-positioned gravity brake), two contact thermometers, 3- way T-mixer, thermostat head with remote sensor (adjustment range 25-50 ºC), surface thermostat, wall mount, return pipe, EPP insulation, all completely assembled.

Heat regulation system for return Return temperature regulation/edition 7 The return heat regulation system is mounted beneath the manifold joint. Depending on the temperature of the return at the boiler entry, flow water is mixed into the boiler return. The result of this is that the boiler attains its operating temperature faster, and in service the return temperature does not fall below a pre-adjustable value. The aim is to avoid condensation in the combustion chamber (increasing the service life) and reducing the emission of pollutants. The level of the minimum return temperature depends on the boiler type. Constant return temperature, regulated by thermostat Complete with circulating pump (EL 180 mm) with 2 m connection cable, two 3-way ball valves (one with manually-positioned gravity brake), two contact thermometers, thermostat valve (adjustment range 30-65 ºC), return temperature sensor in the return ball valve, T-piece, wall mount, return pipe, EPP insulation, all completely assembled.

The boiler circuit can be connected on the left or the right. All connections are prepared for use of Victaulic clips. The top outlets for connection of the heating circuits are in nominal size DN 50. All manifolds are delivered painted, pressure (leak) tested, completely insulated and with two adjustable height base feet. Further, 2 Victaulic couplings and 2 end caps with 1/2" bore and insulations for the Victaulic clips are also supplied. The bores are closed off with blank covers. Alternatively, a KFE tap can be screwed in for draining. The manifold system consists of elements for 2 or 3 heating circuits, which can be combined with each other in any way necessary, depending on the axial separation.
