Chiller corrosion is a common issue in air conditioning and refrigeration systems, where the corrosion of metal components can lead to reduced system efficiency, increased maintenance costs, and even system failure. Chiller corrosion is often caused by the presence of corrosive substances in the coolant, such as water, which can react with the metal components of the chiller to form acidic compounds.
The Importance of Coolant Quality
The quality of the coolant is a critical factor in preventing chiller corrosion. Coolants that contain high levels of dissolved oxygen can accelerate the corrosion process, as oxygen can react with the metal components to form rust and other corrosive compounds. In contrast, coolants with low oxygen levels are less likely to cause corrosion.
The Relationship Between Oxygen and Corrosion
The relationship between oxygen and corrosion is complex, and it involves several factors, including:
- Oxygen levels in the coolant
- Temperature and pressure of the system
- Presence of corrosive substances in the coolant
When oxygen is present in the coolant, it can react with the metal components of the chiller to form acidic compounds, which can accelerate the corrosion process. In addition, oxygen can also contribute to the formation of scale deposits, which can reduce the efficiency of the system and increase the risk of corrosion.

Chiller corrosion is a significant concern in the refrigeration industry, as it can lead to costly repairs, downtime, and even safety hazards. One potential method for preventing chiller corrosion is removing oxygen from the coolant. But does this approach actually work? To understand the role of oxygen in chiller corrosion, let’s first examine the chemistry behind it.
The Corrosion Process
Chiller corrosion occurs when the coolant, typically a mixture of water and glycol, comes into contact with the metal components of the chiller. The corrosion process involves the transfer of electrons from the metal to the water, resulting in the formation of ions and the degradation of the metal. Oxygen plays a crucial role in this process, as it acts as a catalyst, accelerating the corrosion reaction.
In the presence of oxygen, the corrosion reaction is accelerated, leading to a faster rate of metal degradation. This is because oxygen allows the water to become more aggressive, increasing the rate of ion formation and metal dissolution.
The Effect of Oxygen on Corrosion Rates
The effect of oxygen on corrosion rates is well-documented in the literature. Studies have shown that the presence of oxygen can increase corrosion rates by up to 50% compared to oxygen-free conditions. This is because oxygen allows the water to become more alkaline, increasing the pH and reducing the protective oxide layer on the metal surface.
