- They have a longer service life, typically up to 150,000 miles (240,000 km).
- However, they can be more expensive than traditional antifreeze coolants.
Hybrid Organic Acid Technology (HOAT) Coolants
Hybrid organic acid technology (HOAT) coolants are a combination of OAT and traditional antifreeze coolants. They offer the benefits of both technologies, including improved heat transfer, corrosion protection, and environmental friendliness. HOAT coolants are effective in temperatures ranging from -40°C to 120°C (-40°F to 248°F) and are widely used in modern vehicles and equipment.
- HOAT coolants offer improved heat transfer and corrosion protection.
- They have a longer service life, typically up to 150,000 miles (240,000 km).
- However, they can be more expensive than traditional antifreeze coolants.
Silicate-Based Coolants
Silicate-based coolants, also known as silicate-cooled coolants, were introduced in the 1970s as a more environmentally friendly alternative to traditional antifreeze coolants. They are a mixture of silicates and water, with additives to prevent corrosion and improve performance. Silicate-based coolants are effective in temperatures ranging from -40°C to 120°C (-40°F to 248°F) and are widely used in modern vehicles and equipment.
- Silicate-based coolants are more environmentally friendly than traditional antifreeze coolants.
- They have a longer service life, typically up to 150,000 miles (240,000 km).
- However, they can be more expensive than traditional antifreeze coolants.
Propylene Glycol-Based Coolants
Propylene glycol-based coolants, also known as propylene glycol antifreeze, are a more environmentally friendly alternative to traditional ethylene glycol-based coolants. They are a mixture of propylene glycol and water, with additives to prevent corrosion and improve performance. Propylene glycol-based coolants are effective in temperatures ranging from -40°C to 120°C (-40°F to 248°F) and are widely used in modern vehicles and equipment.

- Propylene glycol-based coolants are more environmentally friendly than traditional antifreeze coolants.
- They have a longer service life, typically up to 150,000 miles (240,000 km).
- However, they can be more expensive than traditional antifreeze coolants.
Eco-Friendly Coolants
Eco-friendly coolants, also known as biodegradable coolants, are a new generation of coolants designed to be more environmentally friendly than traditional coolants. They are made from natural ingredients, such as plant-based oils and biodegradable additives, and are designed to be biodegradable and non-toxic. Eco-friendly coolants are effective in temperatures ranging from -40°C to 120°C (-40°F to 248°F) and are widely used in modern vehicles and equipment.
- Eco-friendly coolants are biodegradable and non-toxic.
- They have a longer service life, typically up to 150,000 miles (240,000 km).
- However, they can be more expensive than traditional antifreeze coolants.
Coolant Additives
Coolant additives are substances added to coolants to improve their performance and longevity. They can include corrosion inhibitors, rust inhibitors, and foam inhibitors. Coolant additives can help to extend the life of the coolant, improve its performance, and reduce the risk of corrosion and damage to the system.
- Coolant additives can improve the performance and longevity of the coolant.
