Evapco Cooling Tower Fill Replacement

Evapco Cooling Tower Fill Replacement Guide

In evaporative cooling equipment, Evapco cooling towers are widely used in various industries worldwide for their high efficiency, reliability, and durability. However, with long-term operation, the cooling tower fill inside the cooling tower will gradually age, become clogged or damaged, leading to a decrease in heat dissipation efficiency, an increase in energy consumption, and even affecting the stable operation of the equipment. Therefore, regular cooling tower fill replacement is an important step in maintaining the optimal performance of Evapco cooling tower.

What is the function of Cooling Tower Fill in Evapco Cooling Tower?

The cooling tower fill function is one of the most critical performance cores inside the cooling tower, and its functions include:

1. Increase the contact area between air and water

The filler forms a thin film or droplets of water through a special geometric structure, thereby improving the efficiency of evaporative cooling.

2. Optimize water distribution

Allow the water flow to fall evenly, avoid short flows or hollow areas, and ensure that the entire tower achieves maximum heat exchange efficiency.

3. Extend the residence time of water inside the tower

Improve the heat transfer efficiency between air and water per unit volume.

4. Reduce energy consumption

Efficient fill structure reduces the load on fans and pumps, saving operating costs.

Evapco cooling towers have strict requirements for fill structure and material, so maintaining their good condition is crucial.

Why does Evapco Cooling Tower Fill need to be replaced regularly?

Although Evapco fills are durable, they are still affected by the following factors:

1.Scale accumulation

 Reduces heat transfer efficiency by 20-40%

2.Microbial and algal sludge blockage 

Increased energy consumption

3.Long term high temperature operation 

Deformation or embrittlement of packing material

4.Chemical water quality imbalance

Accelerated corrosion and aging

When the fill is damaged or blocked, it can cause:

1.Cooling effect decreases (water outlet temperature increases)

2.The energy consumption of fans and motors has significantly increased

3.The pressure of the water pump increases

4.Equipment noise increases

5.Potential increased risk of Legionella bacteria

The service life of Evapco Cooling Tower Fill

The common materials for Evapco fillers are PVC or PP, and their service life is usually:

1.PVC filler:

5-8 years (moderate temperature, good water quality)

2.PP filler: 

8-12 years (high temperature, industrial environment)

If the on-site water quality is poor and the maintenance frequency is low, the lifespan may be shortened to 3-5 years.

Standard Process for Evapco Cooling Tower Fill Replacement

When carrying out cooling tower fill replacement, professional construction steps should be followed:

1. Tower shutdown and safety preparation

1）Power outage

2）Drainage

3）Ensure construction space

2. Remove old fills

1）Be careful to remove damaged and aged fillers

2）Avoid damaging the tower foundation support

3. Clean and disinfect the interior of the cooling tower

Including:

1）Remove silt and scale

2）Internal disinfection to reduce bacteria and algae

3）Check the sprinkler system and float

4. Install a new Cooling Tower Fill

1）Cut and match size according to Evapco model

2）Install correctly according to the direction of airflow

3）Ensure that the packing is stacked tightly without gaps

5. Debugging and acceptance

1）Start the system and check the water distribution

2）Monitor the water temperature and airflow situation

3）Record the performance parameters after replacement
