Water treatment plants can’t afford downtime – a single inverter failure can halt operations and cost $10,000+/day. That’s why AUSENIST’s YS620 Pump AC Drive (a Variable Frequency Drive) is trusted by water treatment importers in Southeast Asia and Europe. This frequency converter is built for non-stop use, with multiple protection features to prevent breakdowns.

The YS620 includes dry-run protection (critical for pumps running empty), overvoltage/undervoltage protection, and overload protection. A water treatment plant in Thailand used to face 2-3 inverter failures yearly; after switching to YS620s, they’ve had zero issues in 18 months. “We used to spend $5,000/year on repairs – now that money goes to other upgrades,” said the plant’s technical manager.

As a China inverter manufacturer, AUSENIST optimized the YS620 for global voltage standards (220V-690V, 50/60Hz) and certified it to CE and UL standards. It also supports remote monitoring via RS485, so plant managers can track pump status from anywhere. “Being able to check the AC Drive’s performance on my phone saves me weekly site visits,” added the Thai manager. AUSENIST provides 24/7 English support and fast spare parts delivery to Asia and Europe.

Mining sites overseas face a critical challenge: draining groundwater quickly to avoid flooding tunnels. AUSENIST’s YS620 Variable Frequency Drive (frequency converter) is built for this tough task, with 180% peak torque to handle thick, sediment-rich water.

A South African gold mine used to struggle with pump stalling—their old AC Drive only had 120% torque, leading to 3-4 floods monthly. After switching to YS620s, the mine has had zero floods in 12 months. “The YS620’s torque power pushes through sediment that used to jam our pumps,” said the mine’s operations manager. It also has an auto-reverse function: if sediment blocks the pump, it reverses briefly to clear the blockage—saving $5,000/year on maintenance.

As a China inverter manufacturer, AUSENIST understands mining sites are often remote: it offers bulk delivery via DHL Industrial Logistics (3-week shipping to South Africa) and on-site commissioning by English-speaking technicians. The YS620 also handles high temperatures (up to 65℃) and voltage fluctuations (220V-690V), common in African mining regions. “We don’t have stable power, but the YS620 works perfectly anyway,” added the manager. AUSENIST provides a 3-year warranty for mining applications, longer than the industry average.

Sewage treatment plants overseas face a unique challenge: corrosive fluids that damage standard inverters. AUSENIST’s YS620 Corrosion-Resistant AC Drive (a Variable Frequency Drive) solves this with an anti-corrosion coating and stainless-steel components, making it the top choice for sewage plant importers.

A sewage treatment plant in Indonesia used to replace inverters every year due to corrosion. After installing the YS620, the AC Drives have run for 3 years without issues. “The corrosion resistance is amazing – even with constant exposure to sewage, the YS620 looks new,” said the plant’s technical director. It also has a waterproof design (IP65), so it handles wet environments without damage.

As a China frequency converter manufacturer, AUSENIST optimized the YS620 for sewage pumps’ high-torque needs, ensuring it can handle thick fluids without stalling. It’s certified to CE and ISO standards, so it meets Indonesian import requirements. “The YS620’s torque performance means our pumps never get stuck – even with heavy sludge,” added the Indonesian director. AUSENIST also offers on-site maintenance training for plant staff, so they can handle minor issues themselves. The YS620 saves 25% energy vs. traditional pumps, cutting the plant’s electricity bills by $8,000/year.

Overseas chemical plants need explosion-proof inverters to handle flammable materials—AUSENIST’s YS620 Chemical Plant VFD (a Variable Frequency Drive) is ATEX-certified, making it a top choice for facilities in Germany, the US, and Singapore.

A German chemical plant producing solvents used to face safety fines due to non-explosion-proof inverters. After installing the YS620 (ATEX Zone 2 certified), the plant passed all safety inspections and avoided $15,000/year in fines. The frequency converter also controls circulation pumps to maintain precise fluid temperatures (±1℃), critical for chemical reactions. “Our product quality is more consistent now—rejection rates dropped by 12%,” said the plant’s operations manager.

As a China inverter manufacturer, AUSENIST uses explosion-proof materials (aluminum alloy case, sealed wiring) for the YS620, ensuring it doesn’t ignite flammable vapors. It also has a heat-dissipating design to handle high temperatures from chemical reactions. “The YS620 runs at 55℃ but never overheats,” added the manager. AUSENIST provides ATEX certification documents and 24/7 German-speaking support, so the plant gets fast help. The YS620 saves 23% energy vs. fixed-speed pumps, cutting electricity costs by $7,000/year.

Overseas food processing plants need sanitary inverters to meet FDA/EFSA standards—AUSENIST’s YS620 Food Processing VFD (a frequency converter) has a stainless-steel case and smooth surfaces, making it easy to clean, a top choice for factories in the US, EU, and Japan.

A US food factory producing canned fruits used to fail hygiene inspections due to hard-to-clean inverters. After installing the YS620 (304 stainless steel case, IP65 waterproof), the factory passed all FDA inspections. The Variable Speed Drive controls cleaning pumps to deliver high-pressure water (3 bar) for equipment cleaning, then reduces speed for rinsing. “Our cleaning time dropped by 30%—we can clean more lines per shift,” said the factory’s quality manager.

As a China AC Drive manufacturer, AUSENIST ensures the YS620 meets food industry standards: it’s free of BPA and phthalates, and its surfaces are smooth (no crevices for bacteria). It also has a washdown design, so it can be cleaned with high-pressure hoses. “We wash the YS620 daily—no damage, no rust,” added the manager. AUSENIST provides FDA/EFSA compliance documents and 24/7 English support. The YS620 saves 20% energy vs. fixed-speed pumps, cutting electricity costs by $5,000/year.

Overseas pharmaceutical plants need ultra-clean inverters for purified water systems—AUSENIST’s YS620 Pharma VFD (a Variable Frequency Drive) meets GMP standards, making it a top choice for facilities in Switzerland, the US, and India.

A Swiss pharmaceutical plant producing vaccines used to struggle with water purity due to contaminated pumps. After installing the YS620 (GMP-certified, stainless-steel components), the plant’s purified water meets USP Class VI standards. The frequency converter controls water pumps to maintain constant flow (±2L/min), critical for vaccine production. “Our water purity is consistent now—vaccine yields increased by 8%,” said the plant’s technical director.

As a China inverter manufacturer, AUSENIST uses ultra-clean materials for the YS620: its case is made of 316L stainless steel (resistant to harsh cleaners), and its wiring is sealed to prevent contamination. It also has a HEPA filter to keep dust out of the inverter. “We clean the YS620 with hydrogen peroxide—no damage, no residue,” added the director. AUSENIST provides GMP/USP certification documents and 24/7 English support. The YS620 saves 24% energy vs. fixed-speed pumps, cutting electricity costs by $6,000/year.
