SYR Safety Center 4807 with 12 Liter Expansion Tank

The Safety Center 4807 is used to secure closed domestic hot water heaters (DHW) up to a maximum of 560 liters content, in accordance with DIN 1988, Part 2; DIN 4753, Part 1; DIN 4807, Part 5 and DIN EN 1488. The Safety Center 4807 contains all components prescribed by DIN 1988 and DIN EN 1488 for the inlet-side equipment of DHW. The equipment also includes a flow-through fitting with integrated maintenance shut-off and a flow-through diaphragm expansion tank (DET) with a nominal volume of 12 liters in a compact form.
The Safety Center 4807 includes a double shut-off, an additional connection for a cold water consumer, a backflow preventer, a safety valve with a stainless steel seat and drain funnel, a flow-through fitting with integrated maintenance shut-off for the DET, and a wall bracket with compensation screw connection. The special design of the group allows installation as a corner or straight-through form in horizontal and vertical pipes. The diaphragm safety valve can be rotated 360° to adapt to different installation conditions. The wall bracket enables safe and time-saving installation. The additional replacement cartridges (8 + 10 bar) for the safety valve included in the scope of delivery allow adaptation to different DHW volumes and maximum operating pressures. The Safety Center 4807 is sound-tested and meets the requirements of sound protection class 1.
