Holtop Condensing Exhaust Heat Recovery Air Handling Unit
Our high-performance condensing exhaust heat recovery air handling equipment ensures continuous fresh, pre-conditioned air supply while maintaining strict indoor air quality standards. The intelligent control system enables precise adjustment of airflows and heat recovery rates, adapting seamlessly to varying environmental conditions.
Key Features & Benefits
High standard configuration and reliable operation
Total heat recovery core with patented technology for high efficiency energy saving
Fresh air conditioning with comprehensive indoor air quality controls
No additional independent ventilation system required
No extra cooling tower and outdoor units needed
Independent fresh air conditioning system
Performance Advantage: Compared with conventional chilled water systems, the evaporation temperature is 8-10°C higher with no secondary heat exchange required, increasing refrigeration energy efficiency ratio by over 30%.
High Standard Configuration & Reliable Operation
Engineered for dependable performance with premium components and robust construction.
Advanced Heat Recovery Technology
Achieves over 92% heat recovery efficiency by utilizing both sensible heat (temperature difference) and latent heat (humidity difference) from indoor exhaust. The system uses low-temperature, low-humidity indoor exhaust as cooling air for the evaporative condenser, providing superior condensation effects compared to using outdoor air directly. This innovative approach avoids energy loss from air conversion ventilation and saves approximately 50% of fresh air load energy consumption compared to traditional central air conditioning systems.
Premium Indoor Air Quality Control
Directly processes fresh outdoor air while expelling indoor polluted air through independent exhaust channels. The air isolation heat exchange system ensures absolute air freshness and eliminates cross-contamination. Optional ozone disinfection, ultraviolet sterilization, and high-voltage electrostatic dust removal make this equipment ideal for hospitals and facilities with stringent air quality requirements.
Integrated System Design
During transition seasons, the system operates supply and exhaust fans only for automatic ventilation without compressor activation, eliminating the need for separate ventilation systems. The integrated structure requires no outdoor units, cooling towers, or high-power cooling water pumps, significantly reducing initial project investment while delivering higher operational efficiency.
Advanced Evaporative Condensing Technology
Utilizes tubular evaporative condensing technology that maximizes water film evaporation on fin surfaces, enabling efficient cooling and condensation through mass and heat transfer principles.
Intelligent Control System
Features full Chinese LCD display and microcomputer intelligent controller with advanced programming, comprehensive functions, and high electromechanical integration. The system provides unit start-stop program management, timing control, complete fault alarm systems, and self-diagnostic capabilities. Multiple protection features include phase loss, phase sequence, three-phase imbalance, compressor overload, fan overload, start-up delay, and abnormal exhaust pressure monitoring.
