Modular Distribution Manifold DN25

Modular Distribution Manifold

For use in closed loop design.

Modular design distribution Manifolds allow parallel connection of multiple Zone Modules in order to customize any installation.

default MDM Product Specification (430 KB)

Our modular distribution manifolds simplify installation, extremely shorten assembly time, providing cost and time savings.

 

Available in 2-6 sectional designs, for connection of 2 to 9 heating zones.

MW Hydraulic Separator for Modular Systems 1"

MW Hydraulic sepagator

For use in a closed loop design. Flow up to 3500 L/h (15.4 USgpm).

In conjunction with boilers having high resistance (condensing) or when total flow rate of all parallel running circulators is higher than maximum flow rate of the boiler, the low-loss header provides hydraulic separation, decoupling boiler and system circuits from each other.

default MW HS - Installation & User Manual (456 KB)

It is recommended to use the low-loss header in applications in which the total system flow rate exceeds the maximum boiler flow rate.

PAW strongly recommends the use of a low-loss header in cases where the system head and flow rates are unknown.
