How does the Bock FKX50/980 K compressor perform in extreme high-temperature environments (above 45°C) common in the Middle East and Southeast Asia?
The Bock FKX50/980 K is a high-capacity 6-cylinder compressor with a displacement of 976 cm³, specifically engineered for large bus AC systems. Featuring a lightweight aluminum design and optimized valve plate technology, it is fine-tuned for R134a refrigerant. Its heat dissipation efficiency is approximately 15% higher than similar models, ensuring stable cooling output even at ambient temperatures of 50°C. This prevents slow cooling or frequent thermal shutdowns in tropical and desert climates
With many "refurbished" or "counterfeit" units on the market, how can I verify that I am purchasing a 100% original German Bock FKX50/980 K?
To ensure you are receiving a genuine unit, verify these three key indicators: Nameplate Verification: The original nameplate must be clearly engraved with "Made in Germany." The unique Serial No. can be traced through the Danfoss BOCK VAP software for authenticity.Casting Marks: The compressor body should feature a sharp, clear "BOCK" logo cast directly into the metal housing.
Can I directly replace my existing FK40 or older FK50 series with a 980 K? How easy is it to source spare parts and what is the maintenance cycle?
he Bock FK50 series offers exceptional modularity. The 980 K is one of the highest displacement models in the range, yet it maintains the same standard mounting footprint as the FK50/830 or 775, allowing for a direct "plug-and-play" retrofit to increase cooling capacity. Because it is a global industry standard, spare parts (pistons, valve plates, shaft seals) are readily available in major logistics hubs like Dubai and Singapore. We recommend oil level checks every 500-1,000 hours
