Our advanced air handling equipment ensures continuous delivery of fresh, pre-conditioned air 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. Built for durability with minimal maintenance requirements, the Holtop unit delivers long-term reliability and exceptional performance.
Compared with conventional chilled water systems, our ventilator operates at 8–10°C higher evaporation temperatures. By eliminating secondary heat exchange through chilled water, the refrigeration energy efficiency ratio increases by more than 30%.
Engineered for industrial durability and consistent performance under demanding conditions.
Our patented heat recovery core achieves over 92% efficiency by utilizing both sensible heat (temperature difference) and latent heat (humidity difference) from indoor exhaust. Using indoor exhaust as cooling air for the evaporative condenser provides superior condensation effects compared to direct outdoor air usage, preventing energy loss from air conversion ventilation. During heating cycles, high-temperature, high-humidity room exhaust serves as the heat exchange source. This innovative approach saves approximately 50% of fresh air load energy consumption compared to traditional central air conditioning systems.
The system directly processes outdoor fresh air while expelling indoor pollutants from human activities and building materials. With independent fresh air and 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 modules make this system ideal for hospitals and facilities with stringent air quality requirements.
During transition seasons, the system utilizes fresh air to handle indoor loads by operating only supply and exhaust fans without compressor activation. This eliminates the need for separate ventilation systems, delivering significant energy savings. When temperature requirements are met but humidity control is needed, the system can treat fresh air independently without engaging the main air conditioning host system.
The integrated unit design eliminates the need for outdoor units, cooling towers, and high-power cooling water pumps. This significantly reduces initial project investment while delivering higher operational efficiency. The evaporative condensing unit employs tubular evaporative condensing technology, utilizing water film evaporation on fin surfaces to achieve effective cooling and condensation through mass and heat transfer.
Equipped with full Chinese LCD display and microcomputer intelligent controller, the system offers advanced control capabilities with comprehensive functionality and high electromechanical integration. Features include unit start/stop program management, timing control, comprehensive fault alarm systems, and self-diagnostic capabilities. The controller provides robust automatic control functions with strong anti-interference capabilities and multiple protection systems including phase loss, phase sequence, three-phase imbalance, compressor overload, fan overload, startup delay, and abnormal exhaust pressure monitoring.
