Product Details
Product Overview:
Our company manufactures organic waste gas adsorption and purification units that leverage the highly porous structure and enormous specific surface area of activated carbon—up to 500–2,300 m² per gram—enabling molecular‑level adsorption of organic pollutants from the exhaust stream via intermolecular forces (van der Waals forces). This process effectively purifies the waste gas, ensuring that the treated effluent meets regulatory emission standards.
Physical adsorption and chemical adsorption—physical adsorption primarily relies on intermolecular forces to adsorb nonpolar pollutants, whereas chemical adsorption involves chemical reactions between the active functional groups on the activated carbon surface and the pollutants, converting them into harmless substances.
Synergistic treatment of multiple pollutant types—capable of simultaneously treating a wide range of organic waste gases, including benzene‑, ketone‑, alcohol‑, ether‑, and alkane‑based compounds; it can also handle acidic and alkaline waste gases, sulfide‑containing odorous gases (such as hydrogen sulfide and ammonia), as well as harmful substances like formaldehyde and TVOCs.
Front-end dust removal and cooling (extended function) —— can be used in conjunction with a VOCs exhaust gas purification system, providing functions such as pre‑treatment dust removal, temperature reduction, and acid–alkali neutralization.
Smart Monitoring (Extended Type) — This new Product can be equipped with an automatic detector for monitoring activated carbon adsorption saturation, providing real-time tracking of adsorption saturation and issuing automatic alerts to prompt replacement of the carbon layer; it can also be optionally fitted with an IoT module to enable remote monitoring of device status via mobile phone or PC.

Key considerations for model selection:
Airflow Matching: Based on the airflow rate of the workshop’s ventilation system, select a model with the corresponding treatment capacity and allow for a 10%–20% margin.
Exhaust gas characteristics: Select the appropriate activated carbon type based on the composition of the exhaust gas—coconut-shell-based carbon offers high adsorption capacity, coal-based carbon is cost-effective, and modified carbons can be tailored to target specific VOCs.
Box material: For conventional exhaust gases, carbon steel is recommended; for highly corrosive exhaust gases, PP or 304 stainless steel is preferred; and for high-temperature conditions, stainless steel is the material of choice.
Maintenance convenience: The drawer-type design facilitates easy replacement of the carbon layer, making it ideal for intermittent operation or applications requiring frequent cartridge changes.
Pre-filtration kit: Exhaust gases with high dust concentrations must be equipped with pre‑filter layers such as fiberglass wool to prevent clogging of the activated carbon.
Core use cases:
1. Industrial Organic Waste Gas Treatment: Purification of benzene-series compounds and ester-containing waste gases in industries such as chemical engineering, pharmaceuticals, and printing.
2. Control of Cooking Fume and Odors: Efficiently removes kitchen油烟 particles and food-processing odors.
3. Electronics Manufacturing Purification: The exhaust gases from the etching process, such as xylene, can be reduced to emission concentrations below 4 mg/m³ (requiring a two-stage adsorption system).
4. Temporary exhaust gas treatment: Limited budget or short-term projects.
Note: Activated carbon adsorption units achieve deep purification of exhaust gases through physical and chemical adsorption. Selection should be based on airflow rate, exhaust gas composition, and cost considerations. In industrial applications, regenerative capabilities—such as steam desorption—are preferred, while commercial settings prioritize cost-effectiveness and ease of maintenance.

Cross-flow air curtain machine
The cross‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a tangential fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a flat, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company’s Q‑type air heater is an industrial‑grade, forced‑convection heating unit that uses water or steam as the heat transfer medium. It is specifically designed for large‑space applications such as factory and mine workshops, warehouses, large buildings, and drying rooms. The equipment consists of a fan, an electric motor, and a steel finned‑tube radiator integrated into a single unit. Performance tests have demonstrated its stable and reliable operation. By combining “steam heat exchange with forced air supply,” it rapidly heats the air, delivering highly efficient heating and making it one of the mainstream solutions for heating high‑ceiling spaces.
