Is there a big difference between Heilex Ring and Pall Ring

The difference between Haier ring and Pall ring is mainly reflected in the structural design and performance characteristics, the specific differences are as follows:

### 1. ** Structural differences **

- ** Bauer Ring ** :

The upper and lower layers of misaligned window holes are opened on the side wall of the lacey ring, and the window blades bend into the center of the ring to form a liquid passage. This structure improves the gas-liquid distribution, improves the utilization of the internal surface, and reduces the pressure drop.

** Features ** : Large flux, low pressure, high mass transfer efficiency, suitable for petroleum, chemical, chlor-alkali and other industries.

- ** Haier Ring ** :

The saddle-shaped main body + pyramidal opening ** structure is shaped like a crown, and it is not easy to nest between the fillers and the wall flow effect is small. Its open hole design optimizes gas-liquid distribution with higher specific surface area and porosity.

** Features ** : Good impact resistance, uniform distribution of gas and liquid, suitable for gas absorption, cooling and purification process.

### 2. ** Performance comparison **

| ** Index ** | ** Bauer RING ** | ** HAIER Ring ** |

|----------------|-------------------------------------|-------------------------------------|

| ** Pressure drop ** | is low (50%-70% lower than the lacing ring) | is low (no nesting between the fillers, small wall flow effect) |

| ** Mass transfer efficiency ** | high (20% higher than lacing ring) | high (full gas-liquid contact) |

| ** Anti-plugging performance ** | general (easy to be affected by media impurities) | excellent (structure anti-nesting, not easy to plug) |

### 3. ** Application Scenarios **

- ** Bauer Ring ** :

Widely used in oil fractionation, gas purification, acid and base absorption and other processes, especially suitable for low temperature (60-150℃) environment.

- ** Haier Ring ** :

It is mainly used in gas absorption tower, cooling tower and air purification system, which requires high uniformity of gas and liquid distribution.

### Summary

Both are highly efficient loose packing, but the ** Pall ring focuses on flux and pressure drop optimization **, and the ** Haier ring pays more attention to plugging resistance and gas liquid distribution uniformity **. The selection should be combined with the specific working conditions (such as temperature, media impurities, space restrictions, etc.).
