Frequently Asked Question
A: Conduct a comprehensive load analysis including all connected equipment, motors, lighting, and HVAC systems. Add 20-30% safety margin and consider future expansion. Our engineers provide free load assessment services.
A: Three-phase models are more efficient for balanced loads and required for three-phase equipment. Single-phase large capacity units are used for specific applications or unbalanced loads. Most commercial facilities use three-phase systems.
A: Yes, our systems support parallel operation with automatic load sharing and N+1 redundancy configurations. This ensures continuous operation even during maintenance or component failure.
A: Standard models operate from -10°C to +45°C with up to 95% humidity. Special models available for extreme temperatures, outdoor installation, and corrosive environments with appropriate IP ratings.
A: We provide complete installation services including site preparation, electrical connections, system commissioning, and operator training. Our certified technicians ensure proper installation and optimal performance.
A: Advanced models include touchscreen displays, Ethernet connectivity, SCADA integration, remote monitoring via web interface, and mobile app control. Historical data logging and trend analysis included.
A: Our systems are designed for easy integration with existing electrical infrastructure. We provide detailed installation drawings, coordinate with electrical contractors, and ensure code compliance.
A: Preventive maintenance includes periodic cleaning, connection tightening, and performance verification. IGBT models require minimal maintenance, while servo models need annual brush inspection. We offer maintenance contracts.
A: Yes, we manufacture weather-resistant enclosures rated IP54/IP65 for outdoor installation. Special coatings and materials protect against corrosion, UV radiation, and extreme weather conditions.
A: Commercial installations include 2-year comprehensive warranty with optional extended coverage up to 5 years. We provide 24/7 emergency support, preventive maintenance programs, and guaranteed spare parts availability.
