Holtop's Jiangxi branch has been selected as the HVAC equipment supplier for the Huaneng Xiapu Nuclear Power Base Off-Site Comprehensive Support Facility, a key provincial infrastructure project in Fujian Province, China. This project, representing Holtop's first major contract of 2026, involves the supply of 16 sets of high-performance equipment, including Modular Air Handling Units (MAHUs) and Screw-Type Air-Cooled Chiller (Heat Pump) Units . The deployment of Holtop's advanced HVAC system is designed to provide reliable environmental control for the facility's various functional zones, setting a new industry benchmark for green and reliable operation in nuclear power support infrastructure.
Nuclear power support facilities demand exceptional standards of reliability, safety, and environmental stability. The project presented several key challenges:
- Energy Efficiency Mandates: The facility was designed to meet stringent green building and low-carbon technology demonstration requirements.
- Precise Environmental Control: Different functional zones required accurate temperature and humidity management to ensure optimal working conditions and equipment protection.
- Adaptability to Seasonal Variations: The system needed to provide both cooling and heating efficiently throughout the year.
Holtop engineered a comprehensive solution leveraging its expertise in energy-efficient HVAC technology, featuring two core product lines tailored to meet the project's demanding requirements:
1. Screw-Type Air-Cooled Chiller (Heat Pump) Units
These units serve as the central cooling and heating source for the facility. Key features include:
- High Energy Efficiency: Designed to optimize energy consumption while maintaining superior performance, aligning with the project's green technology demonstration goals.
- Wide Operating Temperature Range: Suitable for operation in outdoor temperatures from -20°C to 48°C, ensuring reliable performance year-round .
- Modular Design: Allows for flexible capacity configuration and phased investment, with the ability to connect up to 16 units in combination .
- Intelligent PLC Control: Advanced control system enables centralized management of up to 128 modular chillers, with features including group mode switching, temperature adjustment, and on/off control .
- Fault-Tolerant Operation: Multiple compressor design ensures that if one compressor fails, the remaining compressors continue operating without affecting the whole system .
2. Modular Air Handling Units (MAHUs)
These units distribute conditioned air to various zones within the facility, featuring:
- Precise Temperature and Humidity Control: Ensures stable environmental conditions for different functional areas.
- Robust Construction: Designed for long-term reliability in demanding applications.
- Easy Integration: Compatible with the central chiller system and building automation controls.
The successful implementation at the Huaneng Xiapu Nuclear Power Base Support Facility demonstrates Holtop's capability to deliver mission-critical HVAC solutions for high-stakes energy infrastructure projects. By combining high energy efficiency, green technology principles, and intelligent control systems, Holtop provides a reliable foundation that ensures environmental stability while supporting the facility's sustainability objectives. This project serves as an industry benchmark for green and reliable HVAC solutions in nuclear power support facilities and similar critical infrastructure applications worldwide.
