Why Energy??

Energy is critical to organizational operations, potentially one of the biggest costs of the organizations regardless their activities

Energy price can not be controlled by a single organization, neither the government policies and the global economy. The company could only manage their energy utilization to reduce the cost.

System to monitor and controlling Energy

UtilizationPenggunaan Energi

EMCS (Energy Monitoring & Controlling System) Is digital technology developed to monitor and evaluate and controllong energy utilization according to the need.

EMCS should function as system interface Between different systems. With EMCS a system coul be integrated with other systems to obtain optimum control and monitoring in one control room.

Main function of EMCS can be used as Remote Controller, Alarm, Status Monitoring, Energy Management and System Integrator.
