Water Control and Optimisation Systems
Actuating Ball Valve:
FUNCTIONALITY & PERFORMANCE:
- Monitech Actuator Ball Valve (ABV) are part of an self-contained, intelligent water management system for dust suppression spray systems that can be retrofitted to a range of applications where water is used.
- Automatic activation of the actuating ball valves (on/off) eliminates the need to mechanically open and shut the water supply.
- The ABVs are available in both single and dual configurations, also as FLP compliant for either in-bye and out-bye underground or surface applications
- Unlike current “load on belt” wheel driven systems that require frictional contact, Monitech ABVs are an intelligent system that is triggered electrically.
- The system only requires AC supply and an open contact to operate the system. In the event of a power failure a battery backup will shut off the water supply. Manual override if required.
- Typical Applications include:
- Feeder breakers
- Belt Transfer points,
- Belts – supplying water sprays on bottom belts where fine dust has accumulated.
- Bunkers
- Surface belts
- Stockpiles
- ABVs form part of a modulated water management system that can be designed to meet operational demands and/or budgetary constraints.
- Flexibility on installations and trouble-free servicing to avoid unnecessary downtime and improving productivity
- The system includes a cost-effective maintenance kit to keep the system operating without the need to replace.
- Proven and reliable technology
- Ease of Operation
- Robust Design

COAL/BLOCKED CHUTE DETECTION SENSOR:
FUNCTIONALITY & PERFORMANCE:
- Monitech Coal and Blocked Chute Detection Sensor is an intelligent autonomous product designed with multiple configurations to assist in the detection of coal on belts and blockages to coal chutes.
- One output is utlised for coal detection and the other for coal blockages. Both detection outputs are wired through separate timer relays, with their own settings.
- The Coal/Blocked Chute detection system is available in an Intrinsically Safe and non-Intrinsically safe versions.
- The sensor can be used as a standalone unit at transfer points but requires a separate PSU to be installed.
- The Coal/Blocked Chute detection sensor has 2 programmable fields:
Coal Detection - The sensor is positioned and programmed above the coal belt where the minimum amount of coal to activate the sensor is set.
- Once coal passes by the sensor a detection field is interrupted, and a signal is sent out to activate the Intelligent Water Management System and/or the Dust Stop Suppression system
- The system shuts off all water once the coal is no longer detected.
Blocked Chute detection: - With the sensor already strategically positioned, the level/height of the maximum allowable pile up of coal is measured from the sensor.
- The blocked chute detection range is then programmed to that measurement.
- Once coal build up exceeds the maximum allowable height, the detection field is interrupted, and a signal is sent out to stop the halt the belt.
- The stop command will stay active for as long as the pile up of coal is detected.
- Proven and reliable technology
- Ease of Operation
- Robust Design
Specifications:
- Relative humidity: <95% non-condensing
- Operating temperature: -10°C to +50°C
- Input Voltage: 24Vdc
Certification:
- Ex rating: Ex ia I
- IA No: MASC M/14-0670X
INTELLIGENT WATER FILLING STATION:
FUNCTIONALITY & PERFORMANCE:
- The Monitech Intelligent Water Filling Station is a cost effective water management system for water refilling points in both underground and surface working environments.
- To assist with ongoing challenges in reducing water wastage and avoidable underground section flooding caused by open water systems, this intelligent Water Filling Station offers a reliable autonomous water refilling point.
- The Filling Station is activated by means of a Green Start button on the enclosure.
- The Filling Station remains open for a preset time period (mine specific) and will automatically close once the time lapses.
- If the time lapses before the equipment’s tank is fully filled up, the Green Start button can be pressed again.
- If the Filling process is complete before the time lapses, the Red Stop button will close off the water supply.
- Typically, the Filling Station is fitted nearby a belt drive, a mounting Frame is available
- The Intelligent Water Filling station is a stand-alone system that only requires a 24Vdc supply.
- The Water Filling Unit is fitted with a battery backup that closes the water supply during a power outage.
- Communications systems to surface are available.
- Installations are backed by the Monitech 24/7/365 service offering if required.
- Strong robust design.
Application Points:
- Surface and Underground – In Bye and Out Bye Application points
- Belt Drives
- Water refilling points
Specifications:
- Max. relative humidity: <95% non-condensing
- Operating temperature: -10°C to +50°C
- Input Voltage: 24Vdc
- Pressure Rating: 50Bar
Water Solenoid:
FUNCTIONALITY & PERFORMANCE:
- Monitech solenoids are an intelligent water management system for dust suppression spray systems that can be retrofitted to a range of applications where water is used.
- Automatic activation of Solenoid systems (on/off) eliminates the need to mechanically open and shut the water supply.
- The Solenoids are available in both single and dual configurations, also as I.S and Non-I.S compliant for either in-bye and out-bye underground or surface applications
- Unlike current “load on belt” wheel driven systems that require frictional contact, Monitech solenoids are an intelligent system that is triggered electrically.
- Typical Applications include:
- Feeder breakers
- Belt Transfer points,
- Belts – supplying water sprays on bottom belts where fine dust has accumulated.
- Bunkers
- Surface belts
- Stockpiles
- Solenoids form part of a modulated water management system that can be designed to meet operational demands and/or budgetary constraints.
