Frequently Asked Questions (FAQs) - Heating Elements & Wind Turbines
1. If I have a sample from another company, can BAILIHAO make it?
Our facilities offer the flexibility to manufacture most heaters and wind turbines available in the market. We typically require drawings and specifications to verify dimensions, power ratings, and other technical details.
2. What kind of electric heaters do I need?
The choice of heater depends on your application:
- Screw plug heaters - Ideal for smaller applications due to their low cost and easy replacement.
- Flanged & circulation heaters - Suitable for large applications requiring high power loads and heating larger liquid volumes.
- Duct heaters - Designed for heating gases efficiently.
- Pipeline circulation heaters - Recommended for applications with pressure requirements.
- Control options - Available with mechanical thermostats or digital controllers for precise temperature control. We also offer moisture-proof and explosion-proof housings for volatile environments.
3. What type of wind turbine do I need?
Choosing the right wind turbine depends on power requirements, wind conditions, and installation environment. We offer a range of small and medium-sized wind turbines for residential, commercial, and off-grid applications, ensuring optimal energy efficiency and performance.
4. What is Watt density?
Watt density (WPSI) measures the permissible wattage over a heater's surface area. For example, water typically has a watt density of 65 WPSI, while oil requires a lower watt density due to its viscosity. Maintaining the correct watt density helps prolong the heater's lifespan, as excessive deposits on the heating element can cause failure by preventing heat dissipation.
5. Brand Description of Heating Elements and Accessories
As a manufacturer, we customize all heating elements and wind turbine components (except for certain standardized parts). For replacement electronic components, please provide the required specifications to our sales team.
6. How often should I maintain the heater and wind turbine?
- Heaters: Regular maintenance depends on the heating medium. Water-based liquids may cause calcium deposits (white powdery substance) on the sheath, requiring frequent cleaning.
- Wind Turbines: Routine maintenance ensures optimal performance and longevity. This includes inspecting blades, checking electrical connections, and lubricating moving parts to prevent wear and tear.
7. Freight and Trade Agreements
- For large-scale heating equipment and wind turbines, shipping costs are estimated based on size and weight, which may differ from the actual shipping cost on the shipment day.
- Standard trade terms: EXW, FOB, CIF (special orders can be negotiated).
- Customers using their own freight agents can arrange direct package collection.
