Origins
The business behind KRONTEK started in 1995 with the design, development and distribution of parts for the modern vehicle. Three decades later that experience covers European and Japanese vehicle platforms.
KRONTEK is the brand of the group dedicated to engine cooling and air conditioning: the parts that carry heat away from the engine, hold the coolant under pressure, and cool and heat the cabin.

What cooling and air-conditioning parts are built for
The cooling system keeps the engine at its working temperature; the air-conditioning circuit and the heating keep the cabin comfortable and the windscreen clear. These are the jobs KRONTEK makes its parts for, and where each one matters.
| Property | Where it matters |
|---|---|
| Passing heat to the air | Radiators, intercoolers and oil coolers: the heat exchangers that carry the heat of the coolant, the charge air and the engine oil into the air stream |
| Holding pressure | Radiator and expansion-tank caps and expansion tanks: the circuit runs under pressure so the coolant boils later, and the tank takes up the coolant as it expands |
| Routing the coolant | Coolant flanges: the housings and outlets that join hoses, thermostat and sensors to the engine without leaks |
| Cooling and heating the cabin | Condensers, evaporators, receiver driers and heater cores: the heat exchangers and the drier of the air-conditioning circuit, and the heat exchanger of the heating |
| Controlling the airflow | Blower resistors and fan control modules: the electronics that set the speed of the cabin blower and of the cooling fan |
| Quality | OEM-compliant quality and aftermarket spare parts, made to the dimensions, the connections and the mounting points of the original part |
| Coverage | European and Japanese passenger cars, each reference identified by the OE number of the original part |
