• ZeroStart

  ZeroStart circulation tank heaters provide reliable engine preheating in all weather conditions. By continuously circulating heated coolant throughout the engine block, these heaters ensure faster starts, quicker warm-up times, and immediate full-load acceptance—even in extremely cold climates.

  Built with a durable, corrosion- and impact-resistant aluminum housing, ZeroStart heaters are available in power ratings from 750 W to 2250 W, making them ideal for professional use in diesel and gas generators, agricultural equipment, compressors, and other stationary engines.

  These units come with either 5/8" or 3/4" hose connections and feature an automatic-reset regulating thermostat for precise temperature control. A built-in overheat safety thermostat provides additional protection, ensuring safe operation in demanding environments.

  ✅ Key Benefits of ZeroStart Circulation Heaters:

  • Faster cold starts through even engine preheating

  • Reduced engine wear and lower emissions

  • Reliable thermostat control for optimal temperature

  • UL, CSA, and CE certified for global compliance

  • Available in thermostat ranges: 16–27 °C (60–80°F), 27–38 °C (80–100°F), and 38–49 °C (100–120°F)

  • Options with or without power plugs, for OEM or end-user installation

  ZeroStart tank heaters are offered with 1.5 m (5 ft) or 3.6 m (12 ft) power cords and support multiple mounting orientations, allowing flexible integration into existing systems.

  Whether you're managing backup power, agricultural machinery, or industrial engines, ZeroStart circulation tank heaters deliver the performance and durability needed for smooth starts and long-lasting operation in any climate..

• FlowStart

  The FlowStart is a compact and efficient electric coolant preheater with an integrated circulating pump, engineered for diesel and natural gas engines in stationary applications such as generator sets (gensets). With available power ratings from 0.5 kW to 2 kW and support for 120V or 230V input, FlowStart ensures reliable cold starts and evenly distributed engine heating in harsh environments.

  Unlike standard heaters, FlowStart features a built-in circulating pump delivering 300 L/h (1.3 GPM) at 1 m pressure head. This active circulation ensures uniform heat distribution throughout the engine’s coolant system, helping engines reach optimal operating temperature faster, even in extreme cold. The result: less wear during startup, reduced fuel consumption, and lower emissions.

  Constructed with a durable cast aluminum housing, Incoloy 800 heating element, and a PA66 electrical cover, FlowStart is built to last. A 2.1 m (6.9 ft) power cable makes installation easy, while the integrated regulating thermostat maintains coolant temperature in the range of 93–104°F (34–40°C) or 95–122°F (35–50°C) depending on model. An added manual-reset safety thermostat ensures safe operation, with cutoff at 230°F (110°C).

  Certified by UL and CE, FlowStart meets stringent safety and performance standards for professional applications. It is ideal for use in standby generators, industrial engines, and fleet vehicles where consistent engine readiness is critical.

  Key Benefits:

  • Fast, reliable engine starts in cold weather

  • Even heat distribution minimizes thermal stress

  • Integrated pump for active circulation

  • Thermostat-controlled heating with safety shutdown

  • Compact, rugged design for long-term use

  Choose FlowStart when reliability, efficiency, and easy integration are essential for keeping engines ready to perform—no matter the temperature.
