DN32 Piston Flow Switch | Industrial Chiller | SAIER - Professional manufacturer of sensors

SAIER DN32 (1-1/4″) Brass Piston Water Flow Switch – Anti-Water Hammer Sensor for Industrial Chillers & Large HVAC

Scaling up your industrial cooling systems requires flow sensors that won’t bottleneck performance or fail under extreme pressure, The SAIER DN32 Piston Flow Switch is engineered specifically for high-volume industrial chillers, commercial HVAC loops, and high-power laser equipment.

Unlike traditional paddle switches whose fins can break off and jam your piping during severe water hammer spikes, our robust brass piston mechanism absorbs pressure shocks flawlessly. Furthermore, the internal magnetic spring return allows for True Omnidirectional Mounting—install it vertically, horizontally, or even inverted without losing actuation accuracy. Secure your heavy-duty infrastructure with reliable NO/NC signal output to prevent catastrophic pump dry-runs.
