How TSG230105MC works
TSG230105MC is a circulation pump with an integrated heater, designed to keep the engine at the optimal temperature before starting. The coolant is heated and continuously circulated, ensuring even heat distribution throughout the engine block.
Through controlled circulation and a stable temperature, the system reduces wear during start-up and improves engine reliability, even in low-temperature conditions. The integrated thermostats automatically manage operation, providing efficient and safe protection.
Heating unit
Built from die-cast aluminum with an Incoloy 800 heating element, providing thermal efficiency and consistent durability.
Circulation pump
A glandless pump designed for quiet operation and continuous circulation of the coolant through the system.
Temperature control
Adjustable temperature from 32 to 176°F for precise control and adaptation to real-world operating conditions.
Integrated safety
Manual-reset thermal protection intended to prevent overheating and keep operation safe.

TopStart
Precise Control • Reliable Starts
TopStart is the range of electric preheaters designed for situations where control matters. Each model is equipped with a circulation pump for uniform heat distribution and consistent temperature throughout the engine.
The temperature is adjustable, allowing the system to be tailored precisely to the application's requirements, regardless of environmental conditions or engine size.
Power makes the difference
Power expressed in kW indicates the heating capacity of the preheater. Higher power means faster heating and consistent performance for engines with a larger coolant volume.
Two operating modes
Continuously Running Pump
Constant circulation, uniform temperature, maximum control.
Pump Synchronized with the Electric Heating Element
Constant circulation, uniform temperature, maximum control.
For industrial applications
The 400 V+ models, including the +CB variants, are intended for industrial applications, where safety, electrical protection, and control are essential.
