Centlube® Long Life OAT Engine Coolant/Antifreeze — 50/50 Pre-Mix

Centlube® Long Life OAT Engine Coolant/Antifreeze is the latest advance in engine cooling technology — a ready-to-use 50/50 pre-mixed ethylene glycol-based coolant engineered for petrol and diesel engines in automotive, fleet, mining, agricultural and industrial applications. Based on patented silicate-free Organic Acid Technology (OAT), it provides virtually non-depleting corrosion protection for all engine metals — often lasting the entire operational life of the engine without replacement.

Available through Orbit Industrial in 20L, 210L drum, 1,000L IBC and bulk formats. Contact us for bulk pricing and delivery across the Western Cape, Northern Cape, Garden Route and Gauteng.

Ready to Use — Do Not Add Water

Centlube Long Life OAT is supplied as a 50/50 pre-mix — ready to pour directly into the cooling system. No mixing required. Provides frost protection to -36°C in the standard 50/50 formulation.

Why OAT Technology Outperforms Conventional Coolants

Traditional IAT (Inorganic Additive Technology) coolants rely on mineral-based inhibitors that deplete rapidly — requiring coolant changes every 2 years or 40,000km. OAT (Organic Acid Technology) coolants use virtually non-depleting organic acid inhibitors that form a thin, self-repairing protective layer on metal surfaces — providing extended, maintenance-free protection across the life of the engine. For mining fleets, agricultural equipment and commercial vehicles running continuous shift patterns, this translates directly into fewer coolant changes, lower maintenance costs and reduced unplanned downtime.

Features & Benefits

Feature Advantage & Operational Benefit
Patented silicate-free OAT technology Virtually non-depleting corrosion inhibitors — extended service life, often for the whole life of the engine, without the need for top-up inhibitor packages or premature coolant changes
Ready-to-use 50/50 pre-mix — no mixing required Eliminates the risk of incorrect dilution ratios in the field — critical for remote mining sites and fleet operations where incorrect coolant concentration causes cooling system failure
Protection for all engine metals — aluminium, cast iron, copper and brass alloys Compatible with all combustion engine cooling system materials — suitable for modern aluminium-heavy engines and older cast iron engine blocks without specification change
Frost protection to -36°C (50/50) — boil protection to +108°C Full temperature protection across the range of conditions encountered in South African mining, agricultural and fleet operations — from high-altitude cold starts to sustained heavy-load high-temperature operation
Meets or exceeds multiple OEM specifications Suitable for use in any combustion engine — petrol or diesel — across all major OEM brands including Cat, Komatsu, Bell, Volvo and most automotive manufacturers
Minimum 8-year shelf life in unopened containers Long storage life supports bulk stock purchasing for mining sites and fleet depots — no product wastage from premature coolant degradation during storage
Silicate-free — no silicate gel formation risk Eliminates the silicate gel formation that can block water pump seals and fine cooling passages in modern high-efficiency engines — a known failure mode of conventional silicate-based coolants
Borate, nitrite, amine and phosphate free (BNAP-free) Improved environmental and health profile — safer for workshop handling and reduces environmental impact of coolant disposal at end of service life
Store above -20°C — stable at ambient temperatures Simple storage requirements for bulk purchasing at fleet depots and remote mining sites — no temperature-controlled storage required under normal South African conditions

Frost & Boil Protection Reference

Concentration (vol%) Frost Protection Boil Protection (1 bar cap)
33% OAT / 67% water -20°C +106°C
50% OAT / 50% water — pre-mix as supplied -36°C +108°C
Note: Maximum recommended concentration Do not exceed 60% OAT Higher concentrations reduce protection

Fantastic, stylish, and easy shoes!

My daughter LOVES these and wears them daily. She says they're really comfy and they slip on easily. They've held up for several months of daily wear so far and are still going strong!

Great for busy feet
Size: 13 Little Kid, Color: Hot Pink/Multi, Size: 13 Little Kid, Color: Hot Pink/Multi
My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
