ANTI-CONDENSATION RECIRCULATION PUMP UNIT WITH THERMOSTATIC CONTROL
Function
The anti-condensation recirculation pump unit allows to connect directly the solid fuel heating source to the heating system or to the buffer tank without the aid of other devices. In fact, the unit encloses the circulating pump, the anti-condensation thermic valve, the excludable natural circulation clapet valve, isolating valves and thermometers in a compact and elegant insulation. It automatically adjusts the temperature of the water returning to the generator to the calibration value of the chosen thermostat.
The device keeps the heat generator at a high temperature (always above that of condensation) in any condition of use, avoiding the formation of sediments both in the boiler and in the chimney flue, thus improving its efficiency and life. Corrosion of the generator or dangerous flue chimney fires are therefore avoided.
Features
Anti-condensation recirculation and distribution pump unit with thermostatic control of the return temperature to solid fuel heating sources.
Cast brass body CB753S. Yellow brass execution.
• Synchronous high efficiency Wilo Para STG/8.
• Maximum working pressure: 10 bar.
• Maximum temperature: 100°C.
• Calibration temperature: 45°C, 55°C, 60°C and 72°C.
• Natural circulation clapet valve: with external control, it can be set on or off according to the type of installation.
• Temperature thermometers: 0-120°C.
Nominal opening temperature: calibration temperature + 10 K.
Available external connections: 1” and 1”1/4 female, 28 mm for copper pipe.
Installation
The anti-condensation recirculation pump unit can be placed on both sides of the heating source, following these directions:
• On the return pipe to the boiler in mixing mode, following the flow directions shown on the body.
• In vertical position (horizontal circulating pump axis) to allow the hydraulic working of the natural circulation clapet valve.
FIELD OF USE
Per potenze Up to 90 kW (con ∆t 30 K) e portata massima di 2600 l/h.
