Both ethylene glycol and propylene glycol are used as coolants to lower the freezing point for industrial use. For many reasons other than toxicity and environmental reasons, it is necessary to know which of the two glycols is present in a given water.

In an interview with Editor Linda Becker, Bonnie Martens of Glen Dimplex Thermal Solutions offers insights about chiller maintenance tips.

Manufacturing processes can produce adverse ambient conditions that can affect employees, production uptime and product quality. Using ancillary systems with production equipment can produce excess heat in the building, sometimes increasing the ambient temperature by 20°F (11°C) or more. These temperature fluctuations can create a difficult environment for employees as well as equipment.

This fall, Process Cooling and Process Heating, its sister publication, will present two hour-long webinars on heat transfer fluids.

A mechanical contractor for a Chicago-based liquid-foods packager had an interesting and challenging cooling application. 

Several types of valves are used to control cooling in the fermentation stage of industrial winemaking.

Heat transfer fluids are tailored to the user’s specific application needs, grouped by low-temperature, glycols and higher temperature solutions.

Jeffcool industrial coolants and heat transfer fluids are produced from inhibited ethylene glycol and propylene glycol specifically to protect brass, copper, solder, steel, cast iron, aluminum and other metals commonly found in industrial cooling and heating systems.
