SIMGAS4 Features

MHI SIMGAS is a versatile integrated process gas/atmosphere management system for processes requiring more than one gas. 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.

SIMGAS: The system consists of three modules: Module 1: SIMGAS MODULE1 (PLC) Module 2: SIMGAS MODULE2 (GAS FLOW) Module 3: MODULE3- (HGI)—flammable gas flare-out system.

FLOWGAS is a new low-price system for a 4-gas module, including flamable gas. Use for premixing and flow control.

1-DataLog is a handheld data logger. Vac-Gas is a vacuum attachment system. O₂ sensors and hand held read out are quoted.

SIMGAS Modules (1,2 & 3). Detailed Descriptions.

Module 1: SIMGAS MODULE1 – (PLC). The SIMGAS MODULE1-(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 – (GAS FLOW) and control of the flammable gas flare system in Module 3 – (HGI SYSTEM). The SIMGAS gives multi level audible and visual alarms, and incorporates safety / emergency shut-down.

Module 2: SIMGAS MODULE2 – (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: SIMGAS MODULE3-(HGI).

The HGI Flammable Gas Flare-out Module is a safety gas flare-out that burns off combustible gases from the process. The module houses an integral burner pilot flame and a UV flame detector for positive flame detection. The HGI constantly monitors the flame and, in the case of a flame-out condition, the PLC control panel initiates to revive the flame. In the event that the flame is not re-ignited within this time, the system initiates a safe shutdown of the process with the required alarm level.
