What is the best material for glycol lines?

Answered by Christopher Steppe

When it comes to choosing the best material for glycol lines, there are a few options to consider. Two popular choices in the industry are GF Coolfit and Pre-Insulated PVC80. Both materials have their own advantages and it ultimately depends on your specific needs and budget.

GF Coolfit is a pre-insulated plastic piping system that is designed for chilled and low temperature glycol applications. It is made from high-quality plastic materials, such as polyethylene or polypropylene, which are known for their durability and resistance to corrosion. The Coolfit system is easy to install and requires minimal maintenance. Additionally, it provides excellent thermal insulation, ensuring that the glycol stays at the desired temperature throughout the piping system.

On the other hand, Pre-Insulated PVC80 is another popular choice for glycol lines. It is made from PVC (polyvinyl chloride), which is a versatile and cost-effective material. PVC80 is known for its high strength and durability, making it suitable for various applications. The pre-insulated version of PVC80 has an additional layer of insulation, providing good thermal stability and preventing heat transfer. This helps to maintain the glycol temperature and minimize energy loss.

In terms of cost, PVC80 tends to be more affordable compared to GF Coolfit. However, it is important to note that GF Coolfit offers better thermal insulation properties, which can result in energy savings in the long run. So, if energy efficiency is a priority for your glycol system, investing in GF Coolfit may be worth considering.

In my personal experience as a brewer, I have worked with both GF Coolfit and Pre-Insulated PVC80 for glycol lines in my brewery. I found that both materials performed well and met my needs. However, I did notice that the GF Coolfit system provided better insulation, resulting in more stable glycol temperatures and reduced energy consumption.

It is also worth mentioning that other materials such as welded stainless steel and copper tubing can be used for glycol lines. Welded stainless steel is known for its strength and resistance to corrosion, making it suitable for high-pressure applications. Copper tubing, on the other hand, is known for its excellent heat transfer properties. However, these materials tend to be more expensive compared to plastic options like GF Coolfit and PVC80.

To summarize, when it comes to choosing the best material for glycol lines, it is important to consider factors such as durability, thermal insulation properties, cost, and specific application requirements. Both GF Coolfit and Pre-Insulated PVC80 are popular choices in the industry, with GF Coolfit offering better thermal insulation and PVC80 being more cost-effective. Ultimately, the decision should be based on your specific needs and budget constraints.
