Coolants & Antifreeze | Alliance Chemical

About Coolants and Antifreeze

Buy inhibited ethylene glycol and propylene glycol coolants from Alliance Chemical in pre-mixed and concentrated formulations. Available in 50/50, 60/40, and 100% concentrations with corrosion-inhibitor packages.

Products In This Collection

This collection includes ethylene glycol 50/50 pre-mixed (CAS 107-21-1), 100% ethylene glycol inhibited, ethylene glycol semiconductor grade (99.5%+), and 100% propylene glycol inhibited (CAS 57-55-6). All inhibited products prevent corrosion, scale buildup, and fouling in metal piping.

Common Applications

Pre-mixed ethylene glycol 50/50 provides freeze protection to −37°C for building HVAC systems, process chillers, and industrial heat exchangers. Propylene glycol inhibited is required for food processing plants, breweries, and any system with potential consumable product contact. These coolants serve data center liquid cooling, solar thermal systems, geothermal heat pumps, and hydronic heating and cooling circuits.

Why Buy From Alliance Chemical

Every coolant product ships with a Safety Data Sheet (SDS) and Certificate of Analysis (COA). Alliance Chemical offers rapid shipping and no minimum orders, from quarts to 330-gallon IBC totes.

Frequently Asked Questions

What is the difference between ethylene glycol and propylene glycol coolants?

Ethylene glycol and propylene glycol are both used as base components in coolants and antifreeze, with ethylene glycol offering superior thermal efficiency while propylene glycol is less toxic and more environmentally friendly. Alliance Chemical provides both types, along with various inhibitor packages tailored for different applications.

Which coolant concentration is recommended for automotive use?

For automotive use, a typical recommendation is a 50/50 mixture of coolant and water, though specific needs may vary based on climate and engine design. Alliance Chemical offers various concentrations to meet specific engine requirements and seasonal adjustments.

How should coolants and antifreeze be stored?

Coolants and antifreeze should be stored in a cool, dry place away from direct sunlight and in a well-ventilated area. Properly labeled, sealed containers ensure stability and safety, which are key factors in maintaining product efficacy. Alliance Chemical emphasizes safe storage practices with all its products.

Is it safe to use propylene glycol-based antifreeze in food processing equipment?

Yes, propylene glycol-based antifreeze can be used in food processing equipment due to it being less toxic and suitable for incidental food contact, provided it is rated correctly. Alliance Chemical offers food-safe grade propylene glycol options for such applications.

What are the common grades of coolants offered by Alliance Chemical?

Alliance Chemical supplies various grades of coolants, including industrial and food-safe grades, each coming with specific inhibitor packages designed for diverse systems like HVAC, automotive, and data centers.

How often should coolants in HVAC systems be replaced?

Coolants in HVAC systems should generally be replaced every 1-3 years, assessing factors like system wear and glycol degradation. Alliance Chemical provides guidance on testing and timely replacement to optimize system performance and longevity.

Which glycol is more environmentally friendly for use as a coolant?

Propylene glycol is generally considered more environmentally friendly than ethylene glycol due to its lower toxicity. Alliance Chemical offers propylene glycol formulations that balance performance with environmental stewardship.

Can I use ethylene glycol coolants in all types of engines?

While ethylene glycol coolants are broadly applicable, their use depends on specific engine requirements and regional regulations. Alliance Chemical provides inhibitor formulations to suit a variety of engine types and regional guidelines.
