Overseas oil refineries need high-temperature-resistant inverters for cooling systems—AUSENIST’s YS620 Oil Refinery VFD (a frequency converter) works at up to 70℃, making it a top choice for refineries in Saudi Arabia, Texas (US), and Russia.

A Saudi Arabian oil refinery used to replace inverters every 18 months due to high temperatures. After installing the YS620 (70℃ high-temp resistant), the inverters have run for 3 years without issues. The Variable Speed Drive controls cooling pumps to adjust flow based on process temperature (high flow at 300℃, low flow at 200℃), ensuring equipment doesn’t overheat. “Our cooling efficiency improved by 15%—we can process more crude oil daily,” said the refinery’s operations manager.

As a China AC Drive manufacturer, AUSENIST uses high-temperature components for the YS620: its capacitors and resistors are rated for 125℃, and its heat sink is made of aluminum alloy for fast heat dissipation. It also has a dust filter to prevent sand from entering (critical for Saudi Arabia’s desert climate). “The YS620’s filter keeps sand out—we only clean it once a month,” added the manager. AUSENIST provides ATEX certification (for hazardous areas) and 24/7 English support. The YS620 saves 22% energy vs. fixed-speed pumps, cutting electricity costs by $12,000/year.

Overseas power plants need high-pressure inverters for boiler feed pumps—AUSENIST’s YS620 Power Plant VFD (a Variable Frequency Drive) delivers 10 bar pressure, making it a top choice for coal, gas, and nuclear power plants in the US, China, and Europe.

A US coal-fired power plant used to struggle with low water pressure in boilers, leading to reduced power output. After installing the YS620, the plant’s boiler feed pumps maintain 10 bar pressure, increasing power output by 5%. The frequency converter also adjusts speed based on boiler demand (high speed during peak power hours, low speed at night), saving 25% energy. “We generate more power now and spend less on electricity for pumps,” said the plant’s maintenance manager.

As a China inverter manufacturer, AUSENIST optimized the YS620 for power plant reliability: it has a redundant design (two control boards) to prevent failures, and its IGBT modules are from Mitsubishi (high-quality and durable). It also supports integration with power plant DCS systems, so operators can control it from the central control room. “The YS620 works seamlessly with our DCS—no extra controls needed,” added the manager. AUSENIST provides UL certification (for US markets) and 24/7 English support. The YS620 has a 10-year lifespan, reducing replacement costs.

Overseas steel mills need heavy-duty inverters for cooling water systems—AUSENIST’s YS620 Steel Mill VFD (a frequency converter) is built to handle vibration and high temperatures, making it a top choice for steel plants in Japan, Germany, and India.

A Japanese steel mill producing automotive steel used to face inverter failures due to vibration from rolling mills. After installing the YS620 (vibration-resistant design, IP54), the mill has had zero inverter failures in 2 years. The Variable Speed Drive controls cooling water pumps to adjust flow based on steel temperature (high flow at 1,500℃, low flow at 800℃), preventing overheating. “Our steel quality is more consistent now—automotive customers are happier,” said the mill’s production manager.

As a China AC Drive manufacturer, AUSENIST uses heavy-duty components for the YS620: its case is made of reinforced steel, and its wiring is secured with vibration-proof clips. It also has a high-torque design (180% starting torque) to handle heavy loads. “The YS620 starts our pumps easily, even under heavy load,” added the manager. AUSENIST provides JIS certification (for Japanese markets) and 24/7 Japanese-speaking support. The YS620 saves 23% energy vs. fixed-speed pumps, cutting electricity costs by $10,000/year.
