What is antifreeze concentrate? 

Antifreeze concentrate is pure antifreeze that must be added to water before being added to an engine’s cooling system. If it is added to the system without being mixed, it can damage the system and requires costly maintenance to be fixed.  

Antifreeze typically features a base of either ethylene glycol or propylene glycol, alongside additives used to improve the capabilities of the concentrate. Due to these ingredients, care must be taken when using antifreeze - propylene glycol and ethylene glycol are both toxic; harmful to humans and animals

When mixed, antifreeze concentrate and distilled water combine to create coolant - most premixed coolants feature a 50-50 ratio. This half-and-half mix is well-suited to temperate climates, preventing overheating or engine lock-up in fairly severe summer or winter weather, respectively.  

However, for very cold or very hot locations, a larger amount of antifreeze should be used. In cold weather, more antifreeze (between 60-70%) reduces the coolant’s boiling point, while in hot, more antifreeze (60-80%) increases the boiling point of the fluid. That is why antifreeze concentrate can be useful for fleet managers and technicians that want to optimise their coolant use.

What are the commercial benefits of antifreeze concentrate for businesses? 

Antifreeze concentrate  provides a range of key benefits for businesses that can ultimately improve their bottom lines:  

  • All-weather operations - If your company operates in any climatic zone that experiences extremes of weather or temperature, antifreeze concentrate lets you easily adapt your coolant mix to meet equipment manufacturer guidelines and improve coolant capabilities.  

  • Reduced maintenance - By using quality antifreeze, and having antifreeze concentrate on hand for when cooling systems need flushing and topping up, businesses can prevent a raft of expensive maintenance issues, including corrosion, overheating, and deposit formation. 

  • Less downtime - With optimised antifreeze concentrate, companies can reduce the amount of downtime their fleets experience, and the knock-on effects this has on profitability. 

  • Bulk antifreeze concentrates - When purchased in bulk, antifreeze concentrates have a smaller cost footprint compared to smaller packs.

Our unique OAT inhibitor technology  

TotalEnergies' concentrated antifreezes feature OAT inhibitor technology. This enables an improved service life compared to standard antifreezes, improving drainage intervals. This improves maintenance costs, reduces the cost of replacing the antifreeze, and is environmentally beneficial too.  

GLACELF concentrated antifreezes also contain a range of antifreeze additives that improve their performance. Combined with OAT inhibitor technology, this confers the following advantages: 

  • Improved transfer of heat from the engine to the cooling system 

  • Improves the lifespan of cooling system water pumps by up to 50%Protects aluminium components, even at high temperatures  

  • Stability against oxidation, even at high temperatures 

  • Exceptional protection against cavitation   

  • Improved antifreeze lifespan  

  • Compatible with most plastics and elastomers  

  • Less scaling and deposit formation in the cooling system 

  • Reduced product disposal requirements  

  • Environmentally friendly 

  • Reduced maintenance requirements 

  • Extreme high and low temperature performance 

  • Helps prevent engines from breaking down.
