1. Air cooler/Air cooled heat exchanger
Product Description
An air cooler utilizes ambient air as a cooling medium, efficiently sweeping across the finned tubes to either cool or condense the high-temperature process fluid within, ensuring optimal thermal management.
This versatile equipment requires minimal space and can be strategically placed indoors or outdoors based on user preferences. Connectivity is facilitated through hoses or steel pipes, with adjustable water pressure displayed via a pressure gauge for precision. Prior to operation, ensure all cut-off valves are securely closed. Post self-circulation, it's crucial to drain the water to prevent debris accumulation, maintaining unobstructed operation.
Product advantages
1. Extends the service life of electronic tubes: Regular water is prone to scaling, necessitating frequent cleaning. This negatively impacts the emission power and lifespan of electronic tubes, with severe cases leading to anode damage.
2. Reduces electricity usage: For example, with a 100KW high-frequency electronic tube setup, the anode water circuit to the ground consumes about 8KW using regular water, compared to roughly 70W with distilled water.
3. Minimizes electrolytic corrosion: Anode high voltage creates a direct current path through water resistance, leading to significant electrolytic corrosion at electronic tube water jacket points. The corrosion rate with regular water is over 100 times that of distilled water.

Product Usage
Primarily utilized for cooling and storage processes in the food industry, including meats, poultry, aquatic products, fruits, vegetables, dairy, and beverages. It also supports the cooling and refrigeration of alcoholic and non-alcoholic drinks, such as beer, and meets the cooling needs of various industrial processes in the chemical, pharmaceutical, mechanical, electronic, and hydroelectric sectors.
2. Air heat exchanger/Radiator
This type of heat exchanger is engineered to efficiently cool or heat air using water, glycol solution, steam, or heat conduction oil. Model selection should be based on specific operational requirements and conditions.
Air heat exchanger can be categorized into: air heater and air cooler.
The versatile air heater comes in several innovative forms, including electric heating, steam heating, and oil heating, among others.
3. Economizer
Product Description:
An economizer is a state-of-the-art device strategically installed at the lower section of the boiler's tail flue, meticulously designed to reclaim the waste heat from exhaust gases. This device ingeniously heats the boiler feedwater into a saturated state under the steam drum's pressure. By harnessing the residual heat from high-temperature flue gases, it effectively lowers the exhaust gas temperature, significantly conserving energy and enhancing the system's efficiency, earning its title as an economizer.
The innovative steel tube economizer, crafted with precision, is unrestricted by pressure constraints and offers flexibility as a boiling type. Typically constructed from robust carbon steel pipes with outer diameters ranging from 32 to 51 millimeters, these tubes may incorporate fins to substantially boost heat transfer efficiency. This advanced economizer consists of horizontally aligned parallel elbow pipes, widely recognized as serpentine pipes.
Product Advantages:
1. Efficiently absorbs the heat from low-temperature flue gases, significantly reducing exhaust temperature, minimizing exhaust losses, and optimizing fuel savings.
2. By preheating feedwater in the economizer before it enters the steam drum, it diminishes the thermal absorption required from the heating surface, allowing the economizer to substitute some of the costlier evaporative heating surfaces.
3. As the temperature of feedwater rises, its entry into the steam drum leads to a reduction in wall temperature difference, thereby diminishing thermal stress and extending the steam drum's lifespan.
Product Usage:
During the initiation phase of a drum boiler, the steam water pipeline lacks circulation, resulting in stagnant boiler feedwater. As boiler combustion intensifies and flue gas temperature escalates, water within the economizer may vaporize, creating localized overheating. To prevent this, an additional pipeline is connected from the steam drum's centralized drainage to the economizer inlet, establishing a recirculation flow that ensures the water remains dynamic, preventing vaporization.
Production Process: Finned Tube Type
Positioned at the tail end of the boiler, where flue gas temperatures are lower, the economizer's primary function is to:
(1) Capture heat from the low-temperature flue gases in the tail flue, effectively reducing exhaust temperatures in low parameter boilers, thereby enhancing thermal efficiency and conserving fuel.
(2) The incorporation of economizers elevates the water temperature entering the drum, reducing the temperature disparity between the drum wall and feedwater, consequently diminishing thermal stress on the drum and extending its overall lifespan.
