Inverted Fixed Point Manifold Mixing Station w/ UPS15-58FC Pump (6 Loops)

**Image may not represent actual product.**

The 172 series manifold mixing station is designed for use in manifold-based hydronic distribution systems. 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.

The manifold mixing station incorporates a thermostatic actuator with built-in sensor 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.

Optional Installation Accessories:

Loop End Cap

• 386500: Manifold Loop End Cap
  These allow you to cap off a loop of the manifold if it will not be used.

Actuators
If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
