Chiller Safety Protocols

Chillers are used to remove heat sources from refrigeration units by way of a vapor compressor. Chillers are commonly found in a variety of industries including food and beverage refrigeration, water filtration, air-conditioning and factory machinery. When working with chillers, it is important to have knowledge of specific safety protocols in order to avoid accidents, injuries and deaths.


Chillers are used to help keep the air cool in air-conditioning units.

When installing you chiller, ensure that you follow all of the manufacturer's recommendations. Each chiller system will have different manufacturer recommendations. Proper installation tools and connections are necessary to complete the installation safety. Specific tools that are needed include a pencil, utility knife and measuring tape, as different states and municipalities may require different plumbing codes and specifications.

Check that the chiller comes equipped with the proper installation parts. Parts can include tubing, connect elbows, connect fittings, a check valve and a wall-mounting clip. Installing a chiller without all of the parts can increase your chances of accidents and injuries.

Fan Obstructions

Whether you are using an under-the-sink water filtration chiller or a large air-conditioning chiller, ensure that the unit's fan is clear of debris, dirt and objects at all times. A fan that is obstructed can cause the chiller to overheat and create a fire hazard. To ensure that the chiller's fan is not obstructed, keep all objects at least 2 inches away from the unit at all times. Regularly checking the fan for excessive dirt and debris will also lessen the chance of the fan's catching fire.

Electrical Requirements

Because chillers are powered by electricity, be sure to follow specific electrical requirements from the manufacturer. For example, under-the-sink water filtration chillers should be grounded when plugged into an electrical outlet. Look for a three-prong plug that will help lessen the chance of receiving an electrical fire. For larger chiller systems that require higher voltages of electricity, ensure that you check both your building's and municipality's electrical codes.

Water Supply Requirements

Different sized chillers will require different levels of water supplies. For example, an under-the-sink water filtration chiller requires water pressures to be anywhere between 30 and 100 pounds per square inch (PSI). Water pressures that are over or under the PSI requirements can cause the machine to malfunction or not provide adequate cooling temperatures to the air or water.

Safety Alarms

For chillers that are located in a mechanical room or refrigeration unit, safety alarms need to be within plain view to all workers. This ensures that all workers will be able to detect any malfunctions that the machine may be presenting, allowing for prompt mechanical repairs to keep the machine in safe working order.
