Bitzer Refrigeration Oil BSE 55 (5L can)

Buy Bitzer BSE 55 Synthetic POE Oil in Saudi Arabia for HFC Refrigerants 

If you walk into ten different HVAC service vans across Saudi Arabia, the Bitzer oil most commonly found in them is BSE 55. There’s a practical reason for that. BSE 55 covers the largest portion of Bitzer compressor service requirements across the medium temperature commercial refrigeration and AC applications that make up the bulk of working service jobs.

Medium temperature commercial refrigeration includes walk-in coolers, beverage coolers, refrigerated display cases, refrigerated transport at chilled (not frozen) temperatures, water coolers, dehumidifiers, and a wide range of similar applications. Combined with R134a AC compressor service, this is where most Bitzer service work happens, and BSE 55 is the specified oil for the majority of those compressors.

For service technicians and small to medium HVAC contractors building out a working oil inventory, BSE 55 is the first POE oil to stock. The other grades cover specific applications. BSE 32 for low temperature work. BSE 170 for larger compressors. BSE 5.2 for HFO refrigerants. BSE 55 is the everyday workhorse covering the most common service requirements.

ISO VG 55 Explained: Why It’s Ideal for Saudi Arabia’s HFC Refrigeration Systems 

ISO VG 55 sits in the middle of the practical refrigeration oil viscosity range. Heavy enough to provide good oil film protection in typical compressor operation. Light enough to flow back through the system at typical evaporating temperatures. The balance is what makes BSE 55 suit such a wide range of applications.

For a Bitzer scroll compressor running R134a in commercial AC, BSE 55 provides the oil film protection needed for the fixed scroll bearing and orbital scroll without being so heavy that oil return becomes an issue. For a reciprocating compressor running R404A in a walk in cooler at moderate evaporating temperature, BSE 55 lubricates the crankshaft and connecting rod bearings while flowing back through the suction line as the refrigerant returns.

For low temperature applications where evaporating temperatures drop significantly, the lighter BSE 32 is more appropriate because oil return at very low temperatures benefits from lighter viscosity. For larger heavy duty compressors, BSE 170 provides stronger film support under higher loads. BSE 55 fills the practical middle ground.

Why HFC Compressors in Saudi Arabia Require POE Oils Like Bitzer BSE 55 

This bears repeating because it remains the most expensive mistake in refrigeration service. HFC refrigerants are not miscible with mineral oils. Using mineral oil in an HFC compressor causes the oil to separate from the refrigerant in the evaporator. The oil pools instead of returning to the compressor. The compressor runs starved of oil. Bearings wear, and compressor failure follows.

POE oils like BSE 55 are specifically engineered to be miscible with HFC refrigerants at typical operating temperatures. This ensures oil leaves the compressor with refrigerant gas, mixes evenly through the system, and returns reliably with the suction gas. Same compressor, same refrigerant, different oil chemistry. Get the oil wrong and the compressor fails. Get it right and the compressor runs for years.

The Importance of Genuine Bitzer POE Oils for Saudi Arabia’s HVAC Systems 

POE oils are particularly sensitive to handling and quality control because they’re hygroscopic. Any moisture absorbed during manufacture, packaging, transport, or storage contaminates the oil. Once moisture gets into the oil, it forms acids in the HFC refrigeration system that corrode internal compressor components.

Cheap relabelled POE oils sold in plain cans of unknown provenance often have moisture issues that don’t show up until the oil is in service. Genuine Bitzer BSE 55 sourced through verified channels comes in sealed Bitzer packaging with quality control traceable to manufacture. For OEM warranty work and any installation where compressor reliability matters, the sourcing is what you’re paying for.

FAQ

Q1. Which Bitzer compressors specify BSE 55 (5L Can) ?

A wide range of Bitzer scroll and reciprocating compressors running medium temperature HFC applications. The exact specification depends on the compressor model. Verify against Bitzer documentation or contact our team with your model number.

Q2. Can I use BSE 55 instead of BSE 32 for low temperature work?

BSE 55 is heavier than BSE 32. For low temperature applications where BSE 32 is specified, the heavier BSE 55 may not flow back through the system at low evaporating temperatures, causing oil return problems. Match the oil to the application.

Q3. Why is BSE 55 the most popular Bitzer POE grade?

Because it covers the largest portion of working Bitzer compressor service jobs. Medium temperature commercial refrigeration plus most R134a AC service represents the largest slice of the field service market, and BSE 55 is the specified oil for most of that work.

Q4. How quickly should an opened can of BSE 55 (5L Can) be used?

As quickly as practical. POE oils absorb moisture rapidly from atmospheric air. For service work, draw what you need and reseal immediately. For workshop use, complete planned work within hours rather than days. Oil left exposed for extended periods should not be used.

Q5: Where is the Bitzer BSE 55 oil imported from?

The Bitzer BSE 55 oil is directly imported from Germany, supplied through Bitzer’s authorised distribution channel, with full traceability back to manufacture on every can.

Q6: What is the oil shelf life of Bitzer Refrigeration Oil BSE 55 (5L Can)?

5 years from the date of production.
