When ambient temperatures drop below 4°C, engine coolant and internal lubricants thicken rapidly. This creates mechanical resistance during cranking, leading to severe starter motor fatigue and potential component damage. The SmartGen HT series water heater eliminates this risk by continuously circulating warm coolant through the engine block, ensuring your generator is always ready to accept a full load immediately.

Designed for extreme field durability, these heaters feature a rugged cast aluminum outer enclosure and self-extinguishing plastic end covers. This series is engineered to protect a wide variety of diesel engine setups up to 13.0 litres of engine displacement.

Low-grade aftermarket heaters often use inferior elements that suffer from rapid scale buildup and localised overheating, leading to premature element failure. Choosing genuine SmartGen hardware ensures your thermal boundaries and automated safety limits align perfectly with your control panel sequencing.

The Generator King supplies fully certified HT series preheaters alongside original SmartGen digital controllers, automatic transfer switches (ATS), and multi-stage battery chargers for total backup system protection.
