R586S-1 Two-way circulation group, with regulator included

Two-way circulation group, with regulator included

Description
The R586S and R586S-1 preassembled groups have been designed to guarantee utmost operational reliability, dimension compactness and, last but not least, simplified installation and service of solar thermal systems.
The circulation groups include:
• ErP-complying circulator, specific for solar applications, controlling the thermo-conductor fluid flow based on the settings of the regulation unit. The ball valves installed on the bottom and top enable to maintain the system
without emptying the circuit.
• Flow meter (mechanical for R586S - electronic for R586S-1) to directly calculate the thermal energy provided by the solar panels.
• Electronic regulation unit with Pt1000 temperature sensors (sold separately for the R586S group).
• Filling group including filling and drain taps and regulation valve.Safety group with 6 bar calibrated safety valve, complying with the PED (97/23/CE - Cat. IV) rule, pressure gauge and outlet for connection to expansion tank.
• Deaerator group with manual discharge valve.
• Ball valves with integrated check valve and each equipped with a thermometer to read solar circuit delivery temperatures.
• PPE insulation cover to ensure an efficient thermal insulation. It includes two removable spacers to install the regulation unit on the group side and carry out adjustment, filling and draining of the system; the cover also enables to view the thermometers mounted on the delivery and return manifolds, the pressure gauge mounted on the safety group, air circulation for cooling of the integrated circulator and, by means of a steel plate on the back, installation on boilers or walls.
