Chillers are large machines that remove heat from a space or object by circulating a refrigerant. They’re used in various settings, from commercial office buildings to industrial manufacturing plants. Because they’re such specialised equipment, they can be expensive to repair or replace—meaning a damaged chiller can be a costly claim.

As a pure device user, you may not be familiar with the inner workings of a chiller hire in London. But it’s important to understand this cooling system’s long and short, especially when you have to assess the damage and determine maintenance or repair costs properly. 

Let’s start first with the basics:

When to Use Them

Chillers are machines that are used to cool things down. They are often used in industrial or medical settings where things need to be kept at a specific temperature. For example, construction sites, lasers, and MRI machines often require chillers to keep them functioning properly. 

These can also be used for various purposes, whether for hire or bought personally. They are sometimes preferred over traditional split systems or package units because they are more efficient and have a longer lifespan. Water-cooled chillers are common in larger facilities, such as airports, hospitals, hotels, shopping malls, commercial buildings, and more.

Air-cooled chillers are more common in smaller facilities where space and water may be limited. They typically have a shorter lifespan but are less expensive to install and maintain than water-cooled chillers. These chillers are often used for restaurants, corporate and sporting events, and temporary structures.

Chiller Problems

Over time, a personally-bought or chiller hire suffers from wear and tear, resulting in the following concerns:

  • Corroded components: Chillers use metal tubes to move water between them and the climate-controlled space. The simple presence of oxygen in water naturally causes corrosion. However, if the water and pipes are treated properly, this can significantly reduce the risk.

    But sometimes, sediment, minerals, and bacteria can enter the system without inadequate water treatment. If there is a large enough buildup of sediment or bacteria that causes oxygenation levels to differentiate, the metals can begin to corrode internally.

    Plus, any point where two different metals are used is at risk of rusting due to different electrochemical properties. No matter how it occurs, corrosion can cause leaks that will damage the chiller’s internal components, reduce efficiency, and possibly affect the surrounding area.

  • Substandard maintenance: A chiller hire is a large, complex machine requiring constant maintenance. If the proper steps aren’t taken, the chiller can experience several issues, such as corrosion, clogging, or decreased efficiency. For example, if water treatment isn’t maintained or cooling towers aren’t cleaned, sediment or particulates can enter the system and cause clogged pipes or poor heat transfer. The condenser of an air-cooled chiller can also become blocked by debris or dirt, which lowers efficiency.

  • Electrical problems: Electrical systems in a chiller hire are very important and can easily be thrown off balance by high voltage surges or wear and tear. If there is a problem with the power supply or grounding, the chiller hire may detect this and shut itself off. Overloading the device can also cause it to overheat and fail.


With these valid concerns, it’s better to get a chiller hire in London than buy one for personal use. Once these devices break down, maintenance and repairs are costly.
