Emergency supply · HANBELL HBR-B01 (POE, 320 class) · RC-2 screw compressor
This is our record of an emergency fill, written from the supplier side of the phone call. HANBELL HBR-B01 is the heaviest grade in the HANBELL HBR-B series of synthetic polyol ester (POE) refrigeration oils, the 320 viscosity class, which our cross-reference table pairs with Qishanr QSL-320H. We supply it in 18.9 L pails with TDS, SDS and a batch COA.
| Item | Detail |
|---|---|
| Customer | A plant running a cold production line (not named) |
| Unit | HANBELL RC-2 screw compressor |
| Trigger | Low-oil-pressure alarm, Tuesday afternoon in July |
| Stock at the plant | Half a can of the old oil |
| Grade we confirmed | HANBELL HBR-B01 — synthetic POE, 320 viscosity class |
| What we shipped | Five 18.9 L pails, dispatched the same evening |
| Timeline | Alarm Tuesday afternoon → grade confirmed within two hours → freight landed next morning → flushed and refilled by noon → line running by 2 pm |
| Since the rescue | The unit holds its charge, with two pails kept in stock as standard |
| Decision taken | HBR-B01 is now the default grade for all three RC-2 units |
We asked the plant to write down how the two days went, because a rescue is only worth repeating if both sides know what made it work. This is their account, as written:
Our Hanbell RC-2 screw compressor went down on a Tuesday afternoon in July — low-oil-pressure alarm, and we were down to half a can of the old oil. Production on that cold line stopped. We called QISHANR at 4pm, sent the compressor model and the current oil code; by 6pm they confirmed HBR-B01 — VG320 POE with a 271°C flash point, exactly what the RC-2 manual specifies — and dispatched five 18.9L pails the same evening. The freight landed next morning, our mechanic flushed and refilled by noon, and the line was running again by 2pm: under 48 hours from alarm to production. Since then, no more surprises — the unit holds its charge, and we keep two pails in stock as standard. That one rescue is why HBR-B01 is now our default for all three RC-2 units, and why we recommend this supplier to the other plants in our group.
An emergency call brings two things: a machine that has stopped and a buyer who needs an answer. We take the same three inputs as any enquiry, faster.
The plant sent the compressor model and the oil code that was in the unit. With those two, plus the quantity needed for a refill, the grade question is answerable: HBR-B01, the 320 viscosity class in the HANBELL HBR-B series of synthetic polyol ester oils.
It is the heaviest grade in that family, the ISO VG 320 class, and it is the grade our cross-reference table pairs with Qishanr QSL-320H. In the series it is specified for air-cooled and flooded screw compressors, which is the duty this RC-2 runs.
A viscosity class is an oil's kinematic viscosity at 40 °C, measured under ASTM D445, and it is the figure that decides whether a screw compressor bearing carries its film. Getting that class wrong is not a preference; it is a bearing load.
The second document in the check is the machine manual. The plant's RC-2 manual specifies the grade and carries a 271 °C flash point for it, and that is the figure their maintenance record holds.
Flash point is where we can point at a published method rather than a claim: the open-cup determination is made under ASTM D92, and it sets the thermal headroom a screw compressor has on its discharge side.
One thing we are explicit about with this grade: we supply it on the cross-reference and on the documentation the customer holds, rather than on a specification table the manufacturer does not publish. Where a figure is not published, we say so and check it with the plant.
An emergency is where grade errors get made, because the pressure to ship something same-day is higher than the pressure to be right. We work the other way round: confirm, then dispatch.
A cross-reference is the matching of one brand's oil grade to another brand's specification, grade for grade. It is what lets a plant buy an equivalent without dropping a viscosity class or changing oil family.
Family comes before grade in that check. A polyol ester and a mineral oil are not interchangeable without a proper changeover, so the oil that was in the machine decides whether a service fill is a top-up or a conversion job.
Then the practical questions: which pack suits the refill, what the site already holds, and what the freight can reach and when. On this call the answer was five 18.9 L pails and a same-evening dispatch.
Documents travel with the pails. A batch certificate of analysis goes out with the shipment, alongside the technical and safety data sheets, so the plant can file the batch reference against the repair.
The last item is the one we would add to any plant's procedure: record the oil code on the unit and keep a service quantity on site. When the alarm comes, the call then starts from a code instead of a photograph of a label.
The plant measured the outcome in three ways.
The unit holds its charge, so the alarm has not come back. The line went back into production inside two days rather than waiting on a supplier's schedule. And the site now keeps two pails in stock as standard.
That last change is the interesting one, because it turns a habit into a specification. A plant holding a service quantity is a plant that can absorb the next alarm; a plant at half a can is one alarm away from stopping.
HBR-B01 is now the default grade for all three RC-2 units on that site, and the site has recommended us to the other plants in its group. That is the outcome we would rather earn than a single order.
Our side of that continuity is unglamorous: the same technical contact answers, the batch documents go out with each order, and the cross-reference is confirmed again if the plant adds a machine.
Most of what makes an emergency fill work is decided before the call: the grade is on record, the pack is in stock, and the documents exist.
On supply, we hold the HANBELL HBR-B series across its grades: HBR-B08 at 127.7 cSt, HBR-B09 at 175.2 cSt, HBR-B04 in ISO VG 220 and HBR-B01 in the 320 class. Each one is paired with our own Qishanr equivalent, so a site can standardise on three machines without holding three supply routes.
On packaging, this grade travels in 18.9 L pails. There is no fixed minimum order on it — the quantity is confirmed per order against the refill and the destination, which is what allows a five-pail emergency order to move on its own.
On documents, every pail order carries a technical data sheet, a safety data sheet and a batch certificate of analysis. On a repair job that record is what links the oil in the machine to a batch, and it is the file a plant needs if the cause of a failure is ever revisited.
On terms, we quote any Incoterms 2020 rule — EXW, FOB, CFR, CIF, DDP and the rest — against the destination, and accept T/T, L/C and PayPal. Private-label supply is available on quotation for distributors.
On the honest side: there are grades for which the compressor manufacturer publishes no figures, and HBR-B01 is one of them. We supply it on the cross-reference, confirm what we can from the machine documentation, and we will not invent a number to fill a table.

Fig. 1 — The stock positions the plant reported, in their own units, with the emergency window marked beneath them.
A: HBR-B01, the 320 viscosity class in the HANBELL HBR-B series of synthetic POE oils, which our cross-reference table pairs with Qishanr QSL-320H. Send the model and the oil code and we confirm it against your machine.
A: On this call the pails left the same evening. Dispatch depends on the quantity, the stock position and the destination: five 18.9 L pails and a 200 L drum are different freight questions. Send the deadline you are working to and we will quote against it.
A: 18.9 L pails, which is the format this plant took five of. There is no fixed minimum order on the grade; the quantity is confirmed per order.
A: A technical data sheet, a safety data sheet and a batch certificate of analysis, so the repair record can reference the delivered batch.
A: No, and that is deliberate. HANBELL does not publish the viscosity, density and flash figures for this grade, so we supply it on the cross-reference and confirm the class against the documentation you hold.
