Product Description

MHI SIMGAS is a versatile integrated process gas/atmosphere management system that finds application in any process where more than one gas is required. The system provides complete stand-alone process gas management on a single platform while integrating itself in the form of interlocks with its peripheral instruments and control systems.

The system consists of three modules:

Module 1: SIMGAS MOD1 (PLC)

Module 2: SIMGAS MOD 2(GAS FLOW)

Module 3: HGI  Flammable gas flare-out system

Module 1: SIMGAS MOD1(PLC)

            The SIMGAS MOD1(PLC) is a PLC based electrical control panel capable of controlling between 2 and 4 different process gasses (standard model is for 4 gasses). The PLC comes loaded with a program that has self diagnostics, Process initiation, Interface with external interlocks, control of gas valves in Module 2 - SIMGAS MOD2(GAS FLOW) and control of the flammable gas flare system in Module 3 - HGI. The SIMGAS gives multi level audible and visual alarms, and incorporates safety / emergency shut-down.

Module 2: SIMGAS MOD2(GAS FLOW)

            The SIMGAS MOD2(GAS FLOW) is a gas delivery panel. The panel incorporates gas manifold, manually settable gas flow meters, ON/OFF gas solenoid valves operated thru the SIMGAS and pressure switches for monitoring of gas pressures.

Module 3: HGI

            The HGI is a flammable gas flare-out system with integral burner with pilot flame and an UV flame detector for positive flame detection. The HGI constantly monitors the flame. In the case of a flame-out condition, the SIMGAS initiates to revive the flame within a stipulated safe time interval. In the event flame is not re-ignited with this time, the SIMGAS initiates a safe shut-down of the process with the required alarm level.
