Bitzer Refrigeration Oil BSE 170 (10L can)

Why Bitzer BSE 170 Oil is Essential for HFC Compressors in Saudi Arabia

The shift from HCFC refrigerants to HFC refrigerants brought a fundamental change in compressor lubrication requirements. Mineral oils that worked perfectly with HCFC systems cannot be substituted into HFC systems. The reason is miscibility, which is one of those technical concepts that seems abstract until a compressor fails because of it.

In any refrigeration system, oil leaves the compressor mixed with refrigerant gas, travels through the entire circuit, and needs to return to the compressor through the suction line. For this to work, the oil and refrigerant have to mix evenly at typical operating temperatures, particularly the cold evaporator temperatures where oil tends to separate. If they don’t mix, the oil pools in the evaporator instead of returning. The compressor runs starved of lubrication. Bearings wear, crankshafts score, and the compressor eventually fails.

Mineral oils are not miscible with HFC refrigerants at typical evaporator temperatures. Polyol ester oils are. That’s the entire technical reason every Bitzer HFC compressor specification calls for POE oil. The BSE series is Bitzer’s POE oil range, and BSE 170 is the ISO VG 170 viscosity grade in that series.

Understanding the Bitzer BSE Series Oil Range KSA

The BSE series spans multiple viscosity grades to match different compressor sizes and applications. BSE 32 is the lighter viscosity for low temperature refrigeration applications using R404A and R507, where lighter oil ensures return at very low evaporating temperatures. BSE 55 is the medium viscosity workhorse for typical HFC commercial refrigeration and AC applications. BSE 170 is the heavier viscosity for compressors needing more robust oil film support. BSE 5.2 is the ultra low viscosity oil specifically for HFO refrigerants.

BSE 170 fits the heavier end of practical HFC service. Larger commercial refrigeration compressors. Chiller compressors where more robust oil film is required. Specific Bitzer compressor models where the manufacturer specification calls for the heavier grade. Always verify which BSE grade your specific Bitzer compressor takes from the manufacturer documentation rather than going by refrigerant alone.

Built for High Ambient HVAC & Refrigeration Conditions in Saudi Arabia 

Operating temperature is one of the strongest factors in oil degradation rate. Compressor discharge temperatures climb as ambient temperatures rise, because the condenser has to reject heat against a hotter ambient. In a 50°C summer afternoon in Riyadh or Jeddah, compressor discharge temperatures can reach levels that test oil thermal stability seriously.

Genuine Bitzer BSE 170 is engineered with thermal and oxidation stability that handles these conditions. Synthetic ester base oils have fundamentally better high temperature stability than mineral oils, and the additive package is designed for sustained high temperature service. That translates to oil holding its specifications through full service intervals rather than degrading early and requiring premature replacement, which is what happens with marginal quality oils in this climate.

Why the 10 Litre BSE 170 Can Is Ideal for Service Contractors 

The 10 litre can sit between the small 5 litre service van size and the larger 20 litre workshop bulk format. For service technicians carrying oil on a refrigeration service van, 10 litres provides enough oil for multiple compressor service jobs without dominating the van layout. For workshops handling medium volume Bitzer service work, the 10 litre format rotates through stock at reasonable frequency so oil is fresh when used.

POE oil quality declines once the can is opened due to moisture absorption from ambient air. Smaller pack sizes that get used quickly maintain better oil quality than large cans that sit partially used for months. The 10 litre format hits a practical balance between convenient volume and stock turnover.

Bitzer BSE 170 Technical Specifications 

Why Buy Genuine Bitzer BSE 170 From Cool.sa 

We supply Bitzer BSE 170 to refrigeration service contractors, HVAC technicians, FM companies, and chiller plant operators across Saudi Arabia. POE oil quality is particularly sensitive to sourcing because moisture contamination during handling and storage destroys the oil’s lubrication performance. Every can we ship comes through verified Bitzer supply channels, sealed from manufacture, with traceable provenance. We offer contractor pricing on bulk and recurring orders, hold real stock in the practical 10 litre format, and confirm compressor compatibility from your equipment nameplate before orders ship.

FAQ

Q1: 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.

Q2: What is the oil shelf life of Bitzer Refrigeration Oil BSE 55 (5L Can)?

5 years from the date of production.

Q3: Which Bitzer compressors specify BSE 55?

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.

Q4: 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.

Q5: 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.

Q6: How quickly should an opened can of BSE 55 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.
