Industry Applications
Textile Industry
The core application sector for the CT2000, especially popular in textile hubs like Southeast Asia and India. Cotton mills face massive lint buildup from roving and spinning frames—regular inverters often fail due to clogged cooling vents. The CT2000's fanless design eliminates lint accumulation, while through-wall installation keeps dust out. Its DEB function enables synchronous smooth deceleration across multiple inverters, preventing yarn breakage caused by inconsistent machine speeds.
Overseas textile factories frequently switch yarn types, and this inverter allows stepless speed adjustment (no pulley changes needed) to fine-tune process curves for different materials and humidity levels. Plus, its networking capability lets factories remotely monitor dozens of spinning machines, streamlining operations in large-scale facilities.
Machine Tool Manufacturing
Ideal for machine tool powerhouses like Europe and Germany, the CT2000 handles metal dust, frequent starts/stops, and variable loads. In small-to-medium Italian machine shops, it controls spindle speeds on precision grinders—adjusting cutting rates for different metals to boost machining accuracy. For large-scale production lines, it supports multi-motor synchronous control to handle heavy-load demands.
The PCB conformal coating resists oil, metal shavings, and coolants common in machining environments, reducing downtime from circuit failures. It seamlessly integrates with overseas factories' automated production lines, aligning with their efficiency goals.
Ceramic Industry
Perfect for high-temperature, high-humidity ceramic production hubs in Southeast Asia and the Middle East. Ceramic factories deal with excessive clay dust from forming machines, kiln ventilation systems, and ball mills—paired with extreme heat near kilns. The CT2000's PCB meets IEC 60721-3-3 CLASS 3C3 protection standards, withstanding these harsh conditions.
It controls ceramic blank processing equipment to ensure uniform thickness via stable speed regulation. When powering kiln ventilation motors, its high overload capacity handles sudden load spikes, preventing temperature fluctuations in the kiln that could ruin batches. This reliability is critical for maintaining consistent ceramic quality in overseas production.
Glass Manufacturing
Suited for glass factories in Europe and the Middle East, where high temperatures (near furnaces) and glass dust (from mixing and processing) create tough operating conditions. In Turkish glass plants, the CT2000 drives raw material mixers—its resistance to instantaneous voltage fluctuations prevents uneven mixing caused by erratic speeds.
Frequently Asked Questions
Q: Can the CT2000 work with the 380V power supply commonly used in my European factory?
A: The overseas CT2000 models we provide are mainly designed for 460V industrial voltage (3-phase). If your factory uses 380V, you have two options: either install a step-up transformer to convert 380V to 460V (make sure the transformer's power matches the inverter's rated power), or contact us to confirm if custom 380V models are available (note: custom orders may take 4-6 weeks longer lead time).
Q: My factory is in Southeast Asia, where the humidity often reaches 90% and there's a lot of dust. Will the inverter break down easily?
A: Don't worry—this is exactly the scenario the CT2000 is built for. Its PCB board has IEC 60721-3-3 CLASS 3C3 conformal coating, which prevents moisture and dust from damaging internal components. But we recommend two extra steps: use the through-wall installation type (model suffix B) to isolate the inverter from the dusty workshop environment, and clean the external heat sink with compressed air every 3 months (avoid water contact). Many textile factories in Vietnam and Thailand use it this way, and the failure rate is very low.
Q: We're a textile mill using roving frames. Can the CT2000 prevent yarn breakage when the machine decelerates?
A: Yes, that's one of its core advantages for textile applications. The built-in DEB (Deceleration Energy Braking) function lets multiple motors decelerate synchronously and proportionally—no more yarn breakage from uneven speed changes. Just set the deceleration time and synchronous ratio through the LCD panel (the manual has a dedicated textile industry parameter template, which is easy to follow). Many Indian and Pakistani spinning mills have tested this, and yarn breakage has dropped by about 30% compared to their old inverters.
Q: How do I connect the CT2000 to our factory's existing Modbus RTU system? Do I need extra modules?
A: No extra modules are needed—every CT2000 comes with a built-in RS-485 port that supports Modbus RTU. You just need to use a shielded twisted-pair cable to connect the inverter's "+" (RS485+) and "-" (RS485-) terminals to your PLC or SCADA system. Remember to set the same baud rate (default is 9600) and slave address for both the inverter and the system. If you're not familiar with the wiring, we can send you a simple connection diagram with photos—many European machine tool factories have used this method to integrate seamlessly.
Q: What's the difference between the wall-mounted (suffix A21C) and through-wall (suffix F00B) models? Which is better for my ceramic factory?
A: The key difference is dust and heat isolation:
- Wall-mounted (A21C): Uses large fans for cooling, suitable for general dusty environments (e.g., small machine shops)
- Through-wall (F00B): Fanless natural cooling, with the main body installed outside the workshop (only the control panel inside)—perfect for heavy dust like ceramic factories (clay dust can't get into the inverter)
For ceramic factories, we strongly recommend the through-wall type. It avoids fan clogging from clay dust and keeps the inverter away from high temperatures near kilns. Factories in Vietnam's ceramic hubs all choose this model, and maintenance frequency is reduced by half.
Q: The voltage in our area fluctuates a lot (sometimes drops by 10-15% suddenly). Will the CT2000 shut down unexpectedly?
A: It has strong voltage fluctuation resistance—most models can handle ±15% voltage deviation. When the voltage drops suddenly, the inverter will automatically adjust the output current to keep the motor running stably (it won't shut down unless the voltage drops below 380V for more than 3 seconds). We've tested it in rural areas of India and Indonesia where voltage is unstable, and it works reliably. If fluctuations are extreme, we can also add a surge protector as an extra layer of protection.
Q: How much does the CT2000 cost to maintain? Do we need special technicians?
A: Maintenance is super low-cost—since it's fanless, there are no fan replacement parts. The only regular maintenance is:
- Clean the heat sink every 3-6 months (depending on dust level)
- Check the wiring terminals once a year to ensure they're tight (vibration from machines can loosen them)
You don't need special technicians—your on-site electricians can do it with basic tools. We also provide a simple maintenance video in English, which shows each step clearly. Many small and medium-sized factories in Southeast Asia handle maintenance themselves without issues.
Q: Can we use the CT2000 with our old 55kW motor (bought 5 years ago)? Do we need to replace the motor?
A: As long as your motor is a 3-phase induction motor (the most common type in factories) and the rated voltage is 460V, it can work with the CT2000—no need to replace the motor. Before installation, just check two things: 1) The motor's rated current doesn't exceed the inverter's rated output current (the 55kW CT2000's rated current is 110A, so your motor's current should be ≤110A). 2) The motor's insulation is good (use a multimeter to test—insulation resistance ≥1MΩ). We've helped many factories in Europe upgrade their old motors with the CT2000, and it's a perfect match.
Q: After installation, the inverter shows an "OC" error (overcurrent). What should we do?
A: "OC" errors are usually easy to fix—here are the top 3 causes and solutions (based on real overseas customer cases):
- Wiring mistake: Check if the motor wires are connected to the inverter's output terminals (U/V/W) correctly—don't mix them with the input terminals (R/S/T)
- Motor short circuit: Use a multimeter to test the motor windings—if there's a short circuit, repair the motor first
- Overload: If the motor is running with too much load (e.g., ceramic forming machine stuck with clay), reduce the load or adjust the inverter's overload protection parameter (extend the protection time appropriately)
If none of these work, take a photo of the error screen and send it to us—our technical team can provide a solution within 24 hours (English support available).
