In 2015, Youngsun Wolfram Vietnam signed an energy audit contract with ITVC Global Co., Ltd. During the audit, the consultants assessed the full tungsten ore production line and the company’s energy consumption..

During the energy audit at Youngsun Wolfram Vietnam Industrial Co., Ltd., ITVC Global found that the company was already using energy relatively efficiently. Further improvement opportunities focused on medium-frequency furnaces, grinding equipment, dust extraction, water pumps and lighting.

Measures proposed during the audit

The figures are estimates in the project record at the time of the audit, not measured savings verified after implementation. Technologies and electricity prices need to be reassessed before applying these proposals today.

Measure in the project record	Annual electricity savings	Cost savings (VND/year)
Develop an ISO 50001:2011 energy management system	22,588	30,990,924
Replace 400 W metal-halide lamps with 250 W high-pressure sodium lamps	16,424	16,424,898
Replace 36 W T8 fluorescent lamps with 28 W T5 lamps	5,830	5,830,012
Replace a 15 kW pump with a 5 kW high-efficiency pump	27,433	37,638,641
Replace a 45 kW fan with a 12 kW fan	48,984	67,205,466

The original table does not specify the electricity unit; consult the audit report before using these figures in calculations. Pump and fan ratings must be selected according to actual flow, pressure and process requirements.

These proposals show that improvement opportunities can arise from both operating practices and equipment selection. Investment priorities should reflect feasibility, production impacts and recalculated benefits.
