Glycol Chiller Service, Maintenance and Repair

Maximus Chillers are a glycol chiller service and maintenance company that carries out fast and effective repairs. The pictures are of low temperature glycol chillers.


Glycol is used in chillers as an anti-freeze where applications have a below (or near) zero temperature. Propylene is non-toxic and food safe. Prices are narrowing between propylene and ethylene, so customers are choosing it more often. Ethylene is toxic so it cannot be used in conjunction with food production. It tends to be used in dirty and very industrial applications. Brine is often used in the industry, usually for larger and colder applications.

Glycol Chiller Maintenance

One of the things we check during a maintenance visit is the glycol condition. To do this we use an instrument to test, then adjust the glycol solution. See Case Study below.

Incorrect Glycol

Water is used as a secondary refrigerant not because it is abundantly available on earth, but because it has very good thermodynamic properties. Water is very good at absorbing and rejecting heat. The only flaw is that water freezes at zero degrees. A call out can occur when the end user reports that the chillers are not doing anything. Sometimes, the onsite engineer can be testing and adjusting the glycol condition incorrectly. The fix is to pump out the water system to vessels and re adjust the glycol condition.

Case Study of Glycol Chillers

A large -10 glycol chiller was having Low Pressure problems. After it had been off for a while it ran okay. Then 5 minutes into the run, however, the low pressure would start dropping off at an increasing rate until a LP trip occurred. The previous company had fitted an expansion valve and pressure tested the system. The onsite engineer said the glycol condition was okay "let me check with my instrument" our engineer said. As he thought- it was a glycol issue. A chiller repair was arranged.
