Customer field report · Hanbell HBR-B01 · RC2 heat pump screw compressors
Direct answer: This case follows one order of Hanbell HBR-B01 refrigeration oil from the first enquiry to the decision to reorder it. Four things carried it: a quick answer on the enquiry, a selection review that separated HBR-B01 from QSL-68H so the wrong lubricant was not ordered, certificates and a COA issued in time for the customer's project inspection, and a delivery that arrived with intact packaging and no leakage. The oil then ran on Hanbell RC2 heat pump screw compressors with stable operation at high temperature, good oil return and no sludge — which is what turned a single order into a repeat one.
| Item | Detail |
|---|---|
| Product | Hanbell HBR-B01 refrigeration oil, 19 L pail |
| Equipment | Hanbell RC2 heat pump screw compressors |
| Selection point | HBR-B01 separated from QSL-68H before ordering, so neither grade was bought by mistake |
| Documentation | Certificates and COA issued in time for the customer's project inspection |
| Delivery | Arrived intact, no leakage |
| Field result | Stable operation at high temperature, good oil return, no sludge |
| Follow-on | Repeat orders planned, and referrals to partner companies |
The source for this case is a single customer message, quoted in full:
“Quick response when we inquired about HBR-B01. The quotation is clear and reasonable. The sales team helped us distinguish HBR-B01 from QSL68H to avoid wrong selection. All required certificates and COA documents were provided promptly for our project inspection. Goods arrived with intact packaging, no leakage. We tested the oil and ran it on Hanbell RC2 heat pump screw compressors. Stable operation under high temperature condition, good oil return, no sludge. Reliable lead time and professional after-sales technical support. We will place repeat orders and recommend to our partners.”
Most of that message is not about chemistry at all. It is about the eight things a maintenance or procurement team actually has to get through: a supplier who answers, a price that can be taken to a budget holder, the right grade chosen, the paperwork that satisfies an inspector, a pail that survives the journey, oil that behaves on the machine, a date the plant can plan around, and someone technical on the other end of the phone. This page follows that sequence.
HBR-B01 and QSL-68H are both refrigeration lubricants supplied in the same style of 19 L metal pail, and that is exactly why the enquiry was worth slowing down. The difference sits inside the label, not on the shelf:
Both are legitimate answers to different questions. Ordering the wrong one is not a small mistake: the plant pays for the pail, for the labour, and for the oil change that has to happen twice. The customer's own summary of that step was that the sales team helped distinguish the two grades "to avoid wrong selection" — which is a service outcome, and the cheapest one in the whole order.
On a project job, the oil has to clear two different gates: the machine, and the paperwork. The customer needed certificates and a COA in time for a project inspection, and both were issued promptly — before the inspection date rather than after it.
A batch of oil that arrives with its paperwork is easier to defend later, because a certificate of analysis ties the delivered pail to a batch and its test values. The same discipline is printed on the pail itself: the item number, the batch reference, and the handling notice that matters most for an ester lubricant.
That printed warning is not decoration. Polyol ester lubricants absorb moisture, which is why the pail is sealed under dry nitrogen and why a half-used drum is a liability unless it is closed properly between fills. Keep the pail sealed until the moment it is used, and close it again immediately afterwards.
The customer's report on delivery was short: goods arrived with intact packaging and no leakage. For a 19 L steel pail that is a specific set of conditions, and it is worth knowing what to look at when the pallet lands.
Hanbell RC2 series units are semi-hermetic twin-screw compressors built for air-conditioning and refrigeration duty and widely used in heat pump systems. Heat pump operation is the demanding half of that description: the compressor spends its life pushing the condensing side up, so the oil sees sustained high temperature rather than the relaxed profile of a comfort-cooling machine.
Three things decide whether an oil holds up there:
The customer's reported result after putting the oil to work was stable operation under high-temperature conditions, good oil return and no sludge — the three things on that list, checked on the machine rather than on paper.
The last part of the customer's message is the part suppliers cannot buy with a discount: reliable lead time, professional after-sales technical support, and an intention to reorder and recommend the supply to partner companies.
Reliable lead time means the plant gets a date it can plan maintenance and production around, and then sees that date met — not a best-case estimate that moves. Technical support means that when a question comes up on site — a top-up, a grade query, a machine that behaves differently than expected — the person answering knows refrigeration compressors rather than only order numbers.
Those two things are why the next order is usually easier than the first: the grade is already fixed, the paperwork format is already accepted by the customer's inspection process, and the delivery rhythm is known.

Full details are on the product page for Hanbell HBR-B01 refrigeration oil. The mineral grade in the same range, HBR-A01, is listed separately.
| Best fit | Where to choose differently |
|---|---|
| Hanbell screw compressors, including RC2 heat pump units, where a project also needs certificates and a COA with the supply. | Machines specified on a different chemistry — for example an ISO VG68 HFC polyol ester — where the documentation calls for that grade. |
| Low-temperature HCFC and hydrocarbon duty, and heat pump screw machines where thermal margin at the discharge end is the constraint. | Circuits whose documentation names a single oil and permits no alternative. |
| Buyers who need the grade and its paperwork to clear a customer or project inspection, on a delivery date the site can plan around. | Buyers comparing on price per litre alone, for whom batch documentation carries no value. |
No, and that is the distinction worth making before an order is placed. HBR-B01 is Hanbell's own complex-ester oil, aimed at low-temperature HCFC and hydrocarbon duty, with HCFC-22, HCFC-502, CFC-13 and CFC-503 among its applications. QSL-68H is an ISO VG68 polyol ester built for HFC systems. Send us the compressor and the refrigerant, and we will confirm which of the two your machine takes.
Certificates and a certificate of analysis for the delivered batch, issued so that they can be presented at a project inspection. The pail itself carries the item number and batch reference that tie it back to those documents. Tell us the inspection requirement at the enquiry stage and the paperwork is prepared with the order rather than after it.
Yes. On Hanbell RC2 heat pump screw compressors this supply has run with stable operation under high-temperature conditions, good oil return and no sludge, which is what the flash point of 271 °C and the ignition point of 282 °C are there to support. Confirm the grade against the compressor documentation and the refrigerant in the circuit before the change is released.
The compressor make and model, the refrigerant, the oil charge, the oil currently in the machine, your annual volume, preferred packaging, destination port, and the documentation your inspection process requires. That is enough for the reply to come back as a supply plan with the paperwork path already mapped out.
