Product Features
1. High-efficiency heat exchange: The surface cooler uses high-quality copper tubes with hydrophilic aluminum fins, double-hem structure, and overall mechanical tube expansion process, ensuring optimal contact between copper tubes and aluminum fins, high heat exchange efficiency, and low air resistance.
2. Low noise and energy saving: The low-noise explosion-proof motor and low-noise explosion-proof centrifugal fan are optimally matched with the unit, combined with well-insulated sound-absorbing materials, ensuring low-noise and energy-efficient operation.
3. Reliable operation: Equipped with an explosion-proof single-phase three-speed motor and high-precision maintenance-free ball bearings for long service life; the fan shaft is nickel-plated for durability.
4. Dry water pan: The water pan is formed by integrated stamping in one step, and the insulation is molded as a whole without welds. The unique drainage channel design ensures smooth drainage without water leakage.
5. Multiple product types, including horizontal concealed, horizontal exposed, vertical exposed, and cassette styles; complete specifications with nine models available; external static pressure options include standard and high static pressure.
6. Uses the latest explosion-proof technology, making the unit safer and more reliable.
