Advanced air handling equipment providing efficient operation and enhanced indoor air quality through intelligent control and heat recovery technology.
Product Overview
Our Holtop Condensing Exhaust Heat Recovery Air Handling Equipment ensures continuous fresh air supply with pre-conditioned air, enhancing comfort while maintaining strict indoor air quality standards. The intelligent control system allows precise adjustment of airflows and heat recovery rates, adapting seamlessly to varying environmental conditions.
With robust construction and low maintenance requirements, the Holtop unit offers long-term reliability and exceptional performance for sustainable ventilation solutions and significant energy savings.
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 additional cooling tower and outdoor units needed
Cooling system operates under independent fresh air conditions
Energy Efficiency Advantage
Compared with conventional chilled water systems, the evaporation temperature of the ventilator is 8-10°C higher, eliminating the need for secondary heat exchange of chilled water to transfer cooling capacity. This results in a refrigeration energy efficiency ratio increase of more than 30%.
High Standard Configuration & Reliable Operation
Engineered for dependable performance with premium components and construction.
Total Heat Recovery Core 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 eliminates energy loss from air conversion ventilation and saves approximately 50% of fresh air load energy consumption compared to traditional central air conditioning systems.
Fresh Air Conditioning & Indoor Air Quality Control
Directly processes fresh air from outside while expelling indoor polluted air through independent exhaust channels. Air isolation heat exchange ensures absolute air freshness and eliminates cross contamination. Optional ozone disinfection, ultraviolet sterilization, and high-voltage electrostatic dust removal make this system ideal for hospitals and facilities with stringent air quality requirements.
Integrated System Design
No Additional Independent Ventilation System Required
During transition seasons, fresh air bears the indoor load with only supply and exhaust fans operating, enabling automatic ventilation without compressor activation. This eliminates the need for separate ventilation systems and provides significant energy savings.
No Additional Cooling Tower and Outdoor Units
The integrated design eliminates outdoor units, cooling towers, and high-power cooling water pumps, reducing initial project investment while maintaining higher efficiency. Tubular evaporative condensing technology utilizes water film evaporation on fin surfaces for effective cooling and condensation.
Advanced Control System
Features full Chinese LCD display and microcomputer intelligent controller with advanced control capabilities and high electromechanical integration. Provides comprehensive functions including unit start/stop program management, timing control, full-function fault alarm, and fault self-diagnosis. The controller offers robust automatic control with multiple protections including phase loss, phase sequence, three-phase imbalance, compressor overload, fan overload, start-up delay, and abnormal exhaust pressure protection.
