China – Rotary Heat Recovery AHU System for Wazhou Group Wind Power Spindle Bearing Project

Project Overview

Holtop successfully delivered 12 rotary heat recovery air handling units (AHUs) for the Wazhou Group Wind Power Main Spindle Bearing Project, a 1-billion-yuan initiative located in the Dalian Free Trade Zone. This smart manufacturing facility features 6 automated bearing processing lines and 3 heat treatment lines. Holtop’s AHUs ensure optimal air quality while significantly reducing energy consumption, contributing to Wazhou Group’s mission to strengthen domestic high-end equipment production and break foreign monopolies in wind power technology.

Product Details of the Air Handling Units

1. Rotary Heat Recovery Technology
   The AHUs use rotary heat exchangers that transfer energy from exhaust air to incoming fresh air via a molecular sieve-coated rotary wheel. This method ensures high heat recovery efficiency, compact unit design, and reduced operational costs.

2. Industrial-Grade Performance
   Holtop's 50U series features high mechanical strength, excellent insulation, and cold bridge isolation. Combined panel and bag filters are used to maintain high air cleanliness in critical production zones.

3. Clean and Energy-Efficient Ventilation
   Designed for large air volumes and low energy consumption, the units are ideal for processing and heat treatment workshops, ensuring proper ventilation without cross-contamination, thanks to advanced sealing and self-cleaning systems.

4. Smart System Integration
   The AHUs are precisely controlled via intelligent monitoring, supporting consistent indoor air quality and production efficiency in accordance with high-end manufacturing needs.
