1. Air cooler/Air cooled heat exchanger
Product Description
An air cooler is an innovative equipment that utilizes ambient air as the cooling medium. It expertly sweeps the outside of a finned tube to efficiently cool or condense the high-temperature process fluid contained within the tube.
This equipment stands alone with a compact footprint, allowing for flexible placement indoors or outdoors to suit user preference. Connection to equipment is facilitated via hoses or steel pipes, with adjustable water pressure displayed on the pressure gauge, ensuring optimal performance. Prior to use, all cut-off valves of high-frequency equipment should be closed to prevent blockages. Once self-circulation is complete, draining via the drain valve ensures debris-free operation, maintaining system integrity.
Product advantages
1. Enhanced longevity for electronic tubes (high-frequency equipment): Ordinary water often leads to scaling, necessitating regular cleaning. Daily scaling affects emission power and lifespan, with severe cases risking anode damage in electronic tubes.
2. Significant electricity savings: For instance, the anode water circuit for a 100KW high-frequency electronic tube equipment consumes approximately 8KW with ordinary water, whereas distilled water reduces this to a mere 70W.
3. Drastic reduction in electrolytic corrosion: Anode high voltage creates a direct current to ground via water resistance, causing considerable electrolytic corrosion at electronic tube water jacket inlets and outlets. Ordinary water's corrosion rate exceeds distilled water's by over 100 times.

Air heat exchangers are categorized into air heaters and air coolers.
Delve into the diverse world of air heaters, which come in various forms such as electric heating, steam heating, and oil heating, each crafted to meet your specific needs and preferences.
3. Economizer
Product Description:
An economizer is an innovative device strategically installed at the lower segment of the boiler's tail flue to recover invaluable waste heat from the exhaust gas. By heating the boiler feedwater into a saturated state under the pressure of the steam drum, it ingeniously captures the heat from high-temperature flue gas. This not only significantly lowers the exhaust temperature but also conserves valuable energy and boosts efficiency, earning its name as an economizer.
The steel tube economizer boasts unmatched flexibility as it is not constrained by pressure and can be utilized as a boiling type. Typically crafted from carbon steel pipes with an outer diameter of 32-51 millimeters, these economizers may incorporate fins to further amplify heat transfer efficiency. It features a clever design of horizontally arranged parallel elbow pipes, commonly referred to as serpentine pipes.
Product advantages:
1. Expertly harnesses the heat of low-temperature flue gas to effectively lower the exhaust temperature, resulting in minimized exhaust losses and significant fuel savings.
2. By pre-heating feedwater in the economizer before it enters the steam drum, the heat absorption requirement on the heating surface is significantly reduced. This enables the economizer to seamlessly replace some of the costly evaporative heating surfaces.
3. The increased temperature of feed water entering the steam drum results in a reduced wall temperature difference, which in turn diminishes thermal stress and significantly extends the steam drum's service life.
Product Usage:
During the critical start-up phase of a drum boiler, the lack of circulation in its steam water pipeline leaves the boiler feedwater in a stagnant state. As the combustion intensifies and the flue gas temperature rises, the water within the economizer risks vaporization, potentially leading to an overheated state. To preempt this, an additional pipeline is connected from the steam drum's centralized drainage to the economizer's inlet, ensuring continuous water flow and preventing vaporization.
Production process: finned tube type
Ingeniously positioned at the boiler's tail end where the flue gas temperature is lower, the economizer serves a pivotal role:
(1) By absorbing residual heat from the low-temperature flue gas at the tail flue, the economizer adeptly reduces exhaust temperatures in low parameter boilers, thereby enhancing boiler thermal efficiency and achieving fuel savings.
(2) The integration of economizers raises the water temperature entering the drum, effectively lowering the temperature disparity between the drum wall and the feed water. This reduction in thermal stress enhances the drum's lifespan.
