McDonnell & Miller
Introduces Low Water Cut-off/Pump Controller for Steam Boilers
| Chicago, IL-March 25, 2002-McDonnell &
Miller has introduced the Series 150E Low Water Cut-Off/Pump Controller for commercial and
industrial hot water and steam boilers. The 150E is a low water cut-off, pump controller
and alarm actuator for boilers, tanks and vessels. Featuring adjustable 60-second
burner-off time delays, the 150E cut-off controller provides continuous primary or
secondary protection against low water conditions and rapid burner cycling. Because of its
field adjustable 3/4” and 1-3/16” pump differentials, the new controller keeps
operation and operating switch levels constant throughout the system’s pressure
range, and significantly reduces pump cycling. The unit’s 1HP burner and pump relays
eliminate the need for electrical starters in many applications. |
|
| Available with manual or automatic reset, the
Series 150E cut-off/ controller is especially suitable for applications with rapidly
shifting water lines, such as vertical tubeless, water tube and small fire tube boilers.
The 157E has an integral water column for convenient gauge tapping mounts. All of the new
models can directly replace current McDonnell & Miller Series 150 head assemblies,
with the addition of two power supply wires. All Series 150E models are UL listed and
Factory Mutual System approved, and operate at a maximum of 150psi (10.5kg/cm2), ambient
temperature of 135F (57°C), and operating temperature (at probes) of 366°F (185°C). |
McDonnell & Miller, a unit of ITT Industries, is a leading
manufacturer of boiler controls, flow switches, liquid level controls and steam specialty
