Caleffi 1725E1A 172 Series Manifold Mixing Station with Pump

The 172 series manifold mixing station is designed for use in manifold-based hydronic distribution systems.The manifold mixing station incorporates a pump and a thermostatic mixing valve which keeps the flow temperature at a constant set value for use in low temperature systems such as floor radiant panels. A removable primary circuit hydraulic separator with check valve is also supplied. The hydraulic separator is essential when there is a primary circuit circulation pump and when radiator circuits or fan coils are controlled by thermostatic or thermo-electric valves. When connecting to a Caleffi HYDROLINKTM or hydraulic separator without a primary pump, the hydraulic separator can be removed and the manifold mixing station can be connected directly. The 172 station, like the TWISTFLOWTM Series 668S1 distribution manifolds, can be configured with 3 to 13 circuit outlets offering similar benefits with built-in sight flow meters/adjustable balancing valves and optional TWISTOPTM thermo-electric zone actuators.
