Antifreeze & Engine Protection for Boats, Motorhomes and Caravans

When temperatures drop, the right antifreeze is essential to prevent costly damage to engines, hoses and tanks. In this category you will find high-quality antifreeze for boats, camping and caravans that perfectly prepare your vehicle or yacht for the cold season. Whether it’s antifreeze for boats and boat engines, freeze protection for fresh and wastewater systems, antifreeze coolant or engine coolant – here you’ll find everything you need for safe and easy winterization.

Make your boat winter-ready – simple and safe

If you want to winterize your boat, the right engine protection is crucial. Our specially formulated antifreeze for boat engines reliably protects against frost and corrosion, keeping your engine powerful and ready for the next season. Whether inboard, outboard or sterndrive – with the right antifreeze you effectively protect cooling systems and engine components from cold and rust.

Antifreeze for fresh- and wastewater systems

Onboard systems also need attention during the winter months. Our freeze protection for fresh- and wastewater systems keeps pipes, tanks and pumps safe from frost. Many products are non-toxic and suitable for use in drinking water systems – ideal for boats, caravans and motorhomes. This ensures your systems will be ready for use in spring without cracks, leaks or contamination.

Versatile antifreeze – from boat to caravan

Our antifreeze concentrates can be used in many ways: as coolant, antifreeze, engine protection or freeze protection for pipes and pumps. Our non-toxic antifreeze products made from biodegradable ingredients are especially popular – perfect if you value environmental friendliness and safety.

Why antifreeze is so important

Without proper antifreeze, even small amounts of residual water can freeze in lines and engines, causing serious damage. Using the right antifreeze for boats, camping and caravans protects your equipment effectively against frost, corrosion and wear. High-quality additives prevent deposits and significantly extend the lifespan of your systems.

Safe winterization – ready for the next season

With the right antifreeze, you can winterize your boat, caravan or motorhome easily and safely. Our products are easy to use, effective and provide maximum protection across your entire system – from the engine and radiator to the freshwater system.

Whether for private use or professional maintenance, our range includes the perfect antifreeze and engine protection products to get you through the winter and ensure a carefree start to the next season.
