Chemical Industry: Precisely controls process fluid temperatures in chemical reaction heat recovery and distillation condensation stages, facilitating efficient and safe chemical production while adapting to diverse corrosive chemical media conditions.

Pharmaceutical Sector:

Provides reliable cooling for pharmaceutical workshops during processes requiring stringent temperature control, such as drug synthesis and freeze-drying, meeting the rigorous GMP standards for equipment cleanliness and stable operation.
Commercial Building Central Air Conditioning:
Delivers core condensation and heat dissipation support for comfortable air conditioning in large shopping centres, office buildings, and hotels. This ensures indoor comfort while reducing building energy consumption and enhancing operational efficiency.

The SPL series evaporative condensers represent an advanced heat exchange solution, developed through the integration and refinement of cutting-edge thermal technologies from both domestic and international sources.

Utilising water and air as cooling media, the SPL series evaporative condensers facilitate heat exchange with high-temperature gaseous refrigerant within the coil, condensing the refrigerant from a gaseous to a liquid state. Internal components include a water distribution system, condensing coil assembly, packing heat exchange layer, and water separator. Externally, it incorporates a circulating water pump, an electronic water descaler, and an axial fan positioned at the top of the coil side. The axial fan creates a negative pressure environment within the unit. During operation, cooling water is distributed through the water distribution system and, driven by the powerful airflow, evenly and completely covers the coil surface. The high-temperature gaseous refrigerant enters from the top of the coils, and the condensed liquid refrigerant
exits from the coil’s base.

During this process, the high-temperature refrigerant undergoes heat exchange with the water and air surrounding the coil, with the airflow significantly enhancing the heat transfer efficiency. The cooling water and air absorb heat, causing their temperatures to rise sharply. Part of the cooling water vaporises into water vapour, and this evaporation carries away substantial heat, which is drawn out by the fan and discharged into the atmosphere. simultaneously, moisture within the hot air is captured by the demister and directed into the sump. Unvaporised high-temperature cooling water flows into the packing heat exchange layer, where it is cooled by the passing air. After thorough cooling, the water returns to the sump to be recirculated by the pump back into the water distribution system for continued operation. Water lost to the atmosphere is replenished in a timely manner, controlled by the float valve in the sump.

Counterflow Evaporative Cooling:
The gaseous refrigerant and spray water flow in the same direction within the heat exchange tube bundle, typically from top to bottom. Simultaneously, the air also passes through the bundle from top to bottom. This co-current flow ensures that the hot fluid comes into contact with the relatively cooler water and air at the very beginning of its passage through the bundle. The significant temperature difference results in a more intense heat exchange during the initial stage.
