McDonnell & Miller 150S-MD Controller Freon The heating elements are constructed

The heating elements are constructed from high-grade nichrome wire in a helix configuration

It is technically identical to the K16WT-72H model

the AC solenoid coil can be serviced or replaced without disconnecting the valve body from the NPT piping

ensuring precise conductance-actuated monitoring

Quiet Operation: Engineered for minimal vibration and reduced noise levels during high-speed cooling or heating cycles

McDonnell & Miller 150S-MD Controller Freon The heating elements are constructedThe McDonnell & Miller 150S MD (Part Number 171802) is a heavy duty combination low water cut off and pump controller designed specifically for commercial and industrial steam boiler applications. This model features a snap acting SPDT switch with Maximum Differential operation, which is critical for preventing rapid pump cycling in high demand systems. It is engineered to maintain precise water levels up to a maximum pressure of 150 psi (10. 5 kg
