Klüber Summit RHT 100

Advanced Refrigeration Compressor Oils for Industrial Applications

Your Requirements – Our Solution

Klüber Summit RHT 100 is a high-performance refrigeration compressor oil formulated with highly purified, hydrogenated mineral oils. It meets the DIN 51 5031, KAA standards, ensuring reliable performance in demanding industrial environments.

Applications

• Klüber Summit RHT 100: Specifically developed for reciprocating piston compressors operating under higher temperatures, such as NH₃ heat pumps, where increased viscosity is required.

Key Benefits

• Reduced Oil Carryover: Highly refined formulation results in significantly lower oil consumption compared to conventional mineral oils.
• Stable Viscosity: Contains minimal volatile hydrocarbons, preventing viscosity fluctuations and premature oil changes.
• Exceptional Chemical Stability:
  • Resistant to ammonia’s effects, preventing black deposits and sludge formation common in refrigeration circuits.
  • Allows for extended oil change intervals and contributes to higher refrigeration efficiency.
• Superior Low-Temperature Performance:
  • Klüber Summit RHT 100 performs reliably down to -30°C.

Compatibility & Seal Performance

• Miscible with mineral oils, alkylbenzenes, and PAO-based refrigeration oils, allowing for top-ups if necessary. However, for optimal performance, a full oil and filter change is recommended.
• Neutral towards chloroprene and neoprene seals commonly used in refrigeration equipment.
• Lower solubility than naphthene-based oils, minimizing seal swelling. In rare cases, switching from naphthene-based oils may cause temporary, minor leaks due to seal shrinkage, which is typically reversible.

Application Guidelines

1. Drain the old oil while the compressor system is still warm.
2. Replace all oil filters and separators, ensuring complete drainage of oil traps.
3. Refill the compressor with Klüber Summit RHT 100.
