This detailed product description is for the DFL 10-150 LR applies to vacuum cooling system filler units of the type that are essential tools for vehicle service and maintenance. The unit, designed for the efficient and air-free filling of modern vehicle complex cooling systems, ensures the exchange and filling of the coolant with outstanding accuracy and reliability.
The DFL 10-150 LR unit offers a professional solution for the de-aeration and filling of cooling systems, minimizing the remnants of air bubbles which can cause serious engine problems. The application of vacuum technology guarantees that the system is completely free of air before the fresh coolant is introduced.
The DFL 10-150 LR unit features several functions that increase workshop efficiency and work quality:
Vacuum Filling Technology: By placing the system under vacuum, it removes air and moisture present in the form of vapor from the cooling system. This ensures perfect sealing and optimal flow of the coolant.
Simple Operation: The unit features an intuitive user interface, allowing for quick and easy setup for different vehicle models.
Broad Compatibility: Specifically designed to be compatible with the cooling systems of most passenger cars, commercial vehicles, and special vehicles.
Fast Operation: The vacuuming and filling processes can be carried out quickly, thus reducing service time.
Reliable Construction: Thanks to its robust design, it withstands the rigors of the workshop environment, ensuring a long service life.
The precise technical parameters of the DFL 10-150 LR cooling system filling unit are as follows:

Traditional pressure-based filling methods often fail to completely remove air from modern, complex cooling systems, especially from around heaters, heater cores, and thermostat housings. The DFL 10-150 LR overcomes this problem:
Total Bleeding: During vacuuming, the air and gases present in the system (including water vapor) are removed. This is especially critical for the thermal management systems of electric vehicles (E-Mobility) and hybrid systems, where air bubbles can cause severe overheating.
Corrosion Prevention: During vacuuming, moisture present in the air is also removed from the system, which reduces the risk of corrosion on metal components.
Precise Level Setting: During filling, the coolant is sucked into the space created by the vacuum, so the system receives exactly the amount of fluid required after evacuation.
The DFL 10-150 LR is the ideal choice for the following areas:
Passenger Car Workshops: General maintenance and repair work.
Truck and Bus Services: Filling of high-capacity cooling systems.
Agricultural and Construction Machinery: Servicing of complex cooling systems in heavy machinery.
E-Mobility and Alternative Drive: Filling and testing of thermal management systems for high-voltage (HV) batteries and electric drivetrains, where temperature regulation is critical.
The device integrates excellently with other diagnostic tools, especially pressure testing kits for the cooling system and CO2 leak detectors.
The DFL 10-150 LR can be used together with devices belonging to the following categories for maximum efficiency:
Hűtőrendszer Ellenőrzőműszerek: For carrying out post-filling pressure tests.
Vacuum Cooling System Filling Accessories: Special adapters and connectors for rarer or special vehicles.
CO2 Leak Detectors: For checking the sealing integrity of the cylinder head.
Coolant Quality Checking Refractometers: To verify the correct concentration of the filled fluid.
This professional vacuum filling unit is an indispensable tool for modern workshops for the professional and durable maintenance of cooling systems.
