Founded in 2002, HOLTOP has consistently focused on the R&D, manufacturing, and provision of healthy, comfortable, and energy-efficient air handling equipment and integrated system solutions. With an annual production capacity of approximately 300,000 sets of energy recovery ventilators, air conditioning units, and heat exchangers, the company exports its products to 103 countries and regions worldwide, supplying both equipment and professional technical support for nearly a thousand engineering projects each year. Recognized as a National High-Tech Enterprise and a Specialized, Refined, Unique, and New (SRUN) Enterprise, HOLTOP is driven by its "Four Dimensions in Architecture" philosophy—Temperature, Humidity, Cleanliness, and Freshness—continuously advancing innovation in air treatment technology for both building and industrial applications.
I. Industrial Process Air Conditioning: Safeguarding High-Standard Production Environments
HOLTOP's industrial air handling units (Series 50U/50B/80B) deliver a maximum airflow of 320,000 m³/h , making them ideal for process and environmental climate control across diverse industrial plants.
In collaboration with global integrators such as Shanghai DURR and Beijing HADEN, HOLTOP has supplied customized air conditioning systems for painting workshops of leading automotive brands including Beijing Benz, Volvo (Zhangjiakou), SAAB, and Geely (Belarus), ensuring a contaminant-free and stable environment for high-quality coating processes.
Tobacco Industry
HOLTOP recently completed a turnkey "remove-and-replace" project for Mengkun Cigarette Factory, involving high-capacity constant temperature and humidity purification air conditioning systems. Five modular air handling units, each with a maximum airflow of 100,000 m³/h, were installed during a limited production shutdown. All systems passed the initial commissioning acceptance, achieving precise control within ±0.5°C temperature and ±2% RH humidity.
II. Digital Intelligent Fresh Air Systems: Building an Air Defense Line for Hospital Buildings
HOLTOP's intelligent fresh air systems specialize in establishing pressure gradients and ensuring indoor air quality for hospitals and clean environments.
Hospital Air Replacement & Pressure Control
These systems ensure organized airflow in critical areas such as operating departments, isolation wards, and ICUs, effectively preventing cross-contamination.
Independent Temperature and Humidity Control Technology and Equipment for Hospital Operating Rooms:
A digital dual-cooling source deep dehumidification heat recovery air handling unit processes fresh air, while a traditional recirculating air conditioning system handles return air. This integrated approach achieves precise, energy-efficient maintenance of constant temperature and humidity in operating rooms.
HOLTOP has mastered a complete spectrum of air-to-air energy recovery technologies, encompassing rotary wheels, plate heat exchangers, heat pipes, run-around coils, and direct expansion condensation systems, significantly reducing energy consumption in buildings.
IV. Air Purification & Dehumidification: Precision Control for Optimal Air Quality
HOLTOP provides comprehensive air treatment solutions, including purification air handing terminals and desiccant dehumidification units, for full-scenario applications.
Purification Air Handling Terminals (25W/50W Series)
With a maximum airflow of 80,000 m³/h and an external static pressure of 2,000 Pa, these units are widely used in hospital operating rooms and various cleanroom environments.
