In the B2B refrigeration oil industry, product quality speaks through actions, not words. A technician who reorders the same compressor oil is making a stronger statement than any marketing campaign — they tested it in real operating conditions, verified it met specifications, and chose to buy again. At Qishanr, we track repeat order patterns as our most important quality metric.
The feedback below comes directly from buyers across Southeast Asia, the Middle East, and Latin America. All quotes are shown verbatim from customer messages — unedited, including original spelling and phrasing. We believe authentic communication is more valuable than polished testimonials.

Qishanr manufactures refrigeration lubricants in Foshan, China with a full product range covering:
Quality assurance: All products are SGS tested for viscosity, pour point, flash point, and acid value. Factory-direct pricing eliminates middleman markup. MOQ as low as 10 pieces for evaluation orders.
Key differentiator: 4 out of 4 featured customers either placed repeat orders or confirmed intent to reorder. In refrigeration oil supply, where switching costs are low and alternatives are abundant, consistent reorders are the strongest quality signal available.
We offer evaluation samples (MOQ 10 pieces) with full SGS test reports. You can also request a spec comparison sheet matching your current oil brand and model. Many customers start with a sample order and convert to regular supply after field verification — as shown in the customer feedback above.
Among active accounts, over 70% of customers place at least one repeat order within 12 months. For our QSL POE series and GS mineral oil series, the repeat rate exceeds 80%. We attribute this to consistent batch-to-batch quality from our own base oil blending facility.
Our products are formulated to match the same ISO viscosity grades and performance specifications. For example, QSL-68H matches Emkarate RL68H in viscosity (66.6 cSt @40°C), pour point (-39°C), and acid value (<0.05 mg KOH/g). We provide detailed cross-reference tables for all major brands. See our CPI CP-4214 Cross-Reference Case and Emkarate RL Compatibility Case for verified equivalence data.
