Frequently asked question

We are always absorbed in the design and manufacture of high-quality products. The products are with integrated efficiency, the smallest noise, energy-saving, security, and full respect for the environment.

  • 01.We are a manufacturing company looking for a stable, reliable, energy-efficient central air conditioning system for our new factory/workshop/warehouse. Can your company provide a suitable solution?

    Absolutely! Providing customized, high-efficiency commercial central air conditioning systems for industrial and commercial clients is our core strength. Whether it's a large factory, high-bay warehouse, or precision workshop, we can design and deliver the optimal solution based on Variable Refrigerant Flow (VRF) systems, air-cooled/water-cooled modular units, or large-scale chiller plants – tailored to your specific spatial structure (area, ceiling height, cooling load requirements), production process characteristics (e.g., equipment heat output), and stringent operational hour demands. Our solutions prioritize operational stability in extreme environments, maximizing energy efficiency to reduce your long-term operating costs (OPEX), and offering intelligent control management.

  • 02.Energy costs are a major concern for us. What are the key energy-saving advantages of your air conditioning systems?

    Energy conservation is paramount in our product design! Our core systems (especially the inverter series) incorporate:

    · Industry-leading inverter compressors and advanced control algorithms: Enable infinite modulation of cooling/heating output based on actual load demand, eliminating the significant energy waste caused by frequent on/off cycling in traditional systems. The Integrated Part Load Value (IPLV) far exceeds national Grade 1 energy efficiency standards.

    · High-efficiency heat exchanger design: Optimized heat transfer surface area and flow paths enhance heat exchange efficiency between refrigerant and air/water. 

    · Intelligent management systems (Optional): Enable zone control, scheduled operation, and energy consumption monitoring & analysis, giving you clear visibility and fine-grained control over energy usage.

    · Heat recovery technology (Select models): In spaces requiring simultaneous cooling and heating, waste heat can be recovered for heating or domestic hot water, significantly boosting overall system efficiency.

    · Case studies demonstrate our systems can save clients up to 30%-50% on air conditioning electricity costs. We are happy to provide detailed energy-saving analysis reports.

  • 03.As a B2B purchaser, we require long-term stable operation and fast after-sales support. How does your company guarantee after-sales service?

    We fully understand the impact of commercial AC downtime on business operations and offer comprehensive worry-free support:

    · Professional Project Delivery: Our experienced engineering team provides turnkey solutions – from site surveys and system design to professional installation and commissioning – ensuring projects are completed on time and to specification.

    · Robust Warranty System: We offer industry-competitive comprehensive warranty periods (e.g., X years on compressors, Y years on the unit – specifics vary by product series) for your peace of mind. 

    · Rapid-Response Service Network: We have established a comprehensive network of service centers and technical support teams across [Mention your primary coverage area, e.g., key industrial regions nationwide / XX region], providing a 7x24 emergency hotline. We commit to [e.g., X-hour response in urban areas, on-site within XX hours].

    · Preventive Maintenance Plans (AMC): Offer tailored Annual Maintenance Contracts, including regular inspections, cleaning, and tuning to prevent failures, extend equipment lifespan, and maximize system efficiency. 

    · Genuine Spare Parts Supply: Ensures fast access to authentic parts, minimizing repair downtime.

  • 04.We need the air conditioning system to integrate with our existing Building Management System (BMS) or enable centralized/remote control. Is this feasible?

    Absolutely feasible! Our commercial air conditioning systems widely support:

    · Open Communication Protocols (e.g., Modbus, BACnet MSTP/IP): Enable seamless integration with your existing Building Automation System (BAS).

    · Centralized Controllers: Manage multiple indoor units from a single controller for unified on/off, mode setting, temperature adjustment, etc.

    · Smart Cloud Platforms (Optional): Monitor AC operating status (on/off, mode, temperature, fault alarms), perform remote control, and access energy data analytics via mobile app or web portal – giving you global oversight, wherever you are. We provide flexible integration solutions and technical support.
