HYDRAULIC SEPARATOR WITH ADDITIONAL FUNCTION OF AIR AND DEPOSIT SEPARATOR USE AND FEATURES The purpose of the Diacom hydraulic compensator is to hydraulically separate the heating circuit and the utilization circuit, when they have different water flow needs. In general, the application is the interface between the primary and secondary system, when the utilization circuit flow is variable and delivers values which are not compatible with the generator needs. Moreover, it has to be used when an anti-condensation function is needed, because it raises the return flow temperature before it gets to the boiler inlet, mixing the outlet and the return flows. Moreover, the Diacom compensator has an additional function: in fact it creates a slow vertical path aimed at helping the upflow air separation and the accumulation of dirt and sludge in the lower part, for an easier discharge to sewers. The connection position has been carefully designed in order to ease the above mentioned functions. PECULIARITY The outlet temperature to the user's units should be equal to the temperature of the flow coming out of the generator: therefore, it is necessary that the G1 flow in the primary circuit is higher than the G2 flow (see diagrams at page 3) in any condition of use. Otherwise, the outlet temperature to the user's units would be lower than the temperature of the flow coming out of the generator. Diacom TECHNICAL FEATURES • • • • Maximum fluid temperature: 90° Maximum fluid pressure: 5 bar Material: carbon steel EN10255 Paint: water-based primer, red. INSULATION TECHNICAL FEATURES • Material: expanded polypropylene (EPP) (density 30 Kg/m3) • Type: embedded shell. APPLICATION EXAMPLES The circuit below ensures that the flow recommended by the manufacturer gets to the production circuit for a proper functioning. On the other hand, there will be variable flows in the utilization circuit, according to the number of outlets installed. COMMON APPLICATION Raising the return temperature from the user's units in order to avoid any condensation in the generator. t1 SYSTEM DIACOM CALCULATION OF THE TEMPERATURE DIFFERENCE The temperature difference on the primary and secondary circuits are calculated as follows: Δt1 = (ta1 – tr1) = Q1 · 0,86/G1 where: Q1 G1 Q2 G2 ta tr SPECIFIC APPLICATION Lowering the flow temperature towards the users' units. is the useful thermal power of the generator; is the water flow in the primary circuit; is the thermal power exchanged by the utilization circuit; is the water flow in the utilization circuit; is the outlet temperature; is the return temperature.

HYDRAULIC SEPARATOR WITH ADDITIONAL FUNCTION OF AIR AND DEPOSIT SEPARATOR THE HYDRAULIC COMPENSATOR IS NECESSARY IN THE FOLLOWING CASES: Compensator YES It is necessary in order to preserve the system and in particular if the system flow and the return temperature reach too low values, which are not compliant with the type of generator (because of thermal exchange needs on the water side or in order to avoid any condensation on the fumes side). GENERATOR SLIDING TEMPERATURE CONDENSING BOILER If the system flow is constant and compliant with the type of generator (installation recommended). It...
