Glycol Chiller System Design

Both eg and pg provides freeze protection for the evaporator pumps and piping as well as rust prevention.

Glycol chiller system design. The parallel design of this setup offers the ability to ferment at ale temps in one vessel and maintain precise serve or crash cooling temps in another vessel. The coolant in a glycol chiller is a water glycol mix that acts as an antifreeze helping achieve a lower freezing point than water. These chillers use non toxic propylene glycol as opposed to ethylene to ensure food safety. This system offers both flexibility and expandability for your home brewery.

Glycol chillers are industrial refrigeration systems that use a type of antifreeze called glycol mixed with water to lower the freezing point in the application of the chilling system. Many of the leading breweries wineries distilleries agriculture food dairy and industrial manufacturers here in the usa and around the world turn. One of the problems that must be overcome in the design of a chilled water system that utilizes antifreeze is derating the coil or heat exchanger depending on the amount of antifreeze used in the system to prevent the condenser water or water side economizing water from freezing. With over 50 years of collective experience in the refrigeration industry g d s chiller expertise goes far beyond the design and implementation of cutting edge glycol chilling systems.

Glycol feed system for chiller condenser water loop the heat. Wpi recommends all chillers use a minimum mix of eg ethylene glycol or fda food and drug administration approved pharmaceutical grade pg propylene glycol depends what the application is.
