Description

I. MONITOR - M (ISI) (CARBON STEEL)
I. MONITOR – M (ISI) (CARBON STEEL)

The Monitor Model – M is durable manual controlled  monitor for fixed installation as well as for trailer mounted unit. The monitor is generally used for
protection of flammable liquid storage tanks, loading racks, dykes marine and many other industrial applications.
The Monitor possess several design features that provides ease of operation, minimum maintenance and resistance to normally destructive environments. The monitor is fitted with solid bore straight stream nozzle. The monitor has welded carbon steel water way. All steel parts are hot dip galvanized and painted for excellent corrosion resistance. The vertical and horizontal rotation is through corrosion resistant bronze swiveling joint with double row of stainless steel ball bearing. Both vertical and horizontal movements are controlled with handle with twist lock. The monitor has large flow capability and can be manually operated by a single fire fighter. The design  ensures to prevent jet reaction forces from effecting the horizontal and vertical position of the monitor. The monitor has the ability for 360 deg. continuous  horizontal rotation and angle of elevation is adjustable
with fix stop from+90 deg. above horizontal to -45 deg. below horizontal.  The water vanes in discharge tube reduces the turbulence and friction loss, thus increasing the nozzle performance to achieve greater range. To ensure desired performance, the friction loss through monitor must be considered while selecting the nozzle and flow through the monitor with reference to available base pressure at inlet of the monitor.
