Next-Generation Coolant for Local Fleets
Fuchs Lubricants South Africa has announced the local introduction of Fricofin LD 50, a premium-performance, ready-mix coolant engineered to meet the increasingly complex thermal management requirements of modern heavy-duty and mixed fleets operating across Southern Africa.
As winter conditions take hold in key transport corridors, including the Highveld, Western Cape, and northern freight routes, cooling systems are exposed to wider thermal cycles, cold starts, and sustained high-load operation. Under these conditions, coolant formulation is critical not only for protection against freezing, but also for long-term corrosion control, stable heat transfer, and protection of increasingly sensitive engine components.
Suited to modern engines
Fricofin LD 50 uses advanced X‑OAT coolant technology, combining monoethylene glycol and demineralised water with long‑life organic acid inhibitors and select inorganic accelerators. This delivers fast corrosion protection alongside long-term stability.
Free of nitrites, borates, silicates, and phosphates, it avoids issues like deposits, gel formation, and abrasive wear, ensuring efficient heat transfer. The formulation is especially suited to modern Euro‑spec diesel engines operating under high thermal and emissions stress.
Severe duty
For heavy‑duty and long‑haul use, the product protects against cavitation, corrosion, and deposits under high loads and extended service intervals. It is compatible with all major cooling system materials and has been proven in severe‑duty applications without the need for initial SCAs, simplifying maintenance while delivering stable thermal performance and long‑term protection in demanding South African operating conditions.
Supplied as a 50 vol% pre-diluted ready‑mix, Fricofin LD 50 can be filled directly into the cooling system, eliminating dilution errors and ensuring consistent corrosion inhibitor levels across the fleet. The formulation provides protection against freezing down to –40 °C while maintaining effective boiling point control under sustained operating temperatures.
This broad approval profile makes Fricofin LD 50 ideal for mixed fleets, simplifying workshop operations and reducing inventory duplication. In addition, the coolant incorporates a bittering agent to enhance safety, along with a specialised additive that neutralises residual brazing flux from Controlled Atmosphere Brazing (CAB) radiators, helping maintain long‑term cleanliness in modern aluminium cooling systems.
