Frequently asked questions about CPI-4628-100

What is needed to change over to CPI-4628-100 from the oil in use?

Per the TDS, PAO oils are compatible with mineral oil, so no transition oil is needed when the machine is clean; the old oil must still be drained fully and the oil filter and separator element replaced so that residue and aged oil are not carried into the new fill. Do not top up over PAG or POE oils (not miscible) – those cases require flushing. A Hop Tien engineer confirms the base oil in use before the change.

How much does CPI-4628-100 cost?

Price depends on pack size (208 L drum) and quantity; Hop Tien quotes within 24 working hours with delivery terms (warehouse at Song Than Industrial Park, nationwide delivery). Include the machine and the viscosity grade currently used so an engineer can confirm the right product.

Where can I buy genuine CPI-4628-100 in Vietnam?

Hop Tien is the authorized distributor of Lubrizol Fluid Engineering (CPI brand) in Vietnam: goods are imported officially with a certificate of origin (CO), certificate of quality (CQ), CoA per batch and the Vietnamese supplementary label required by law. How to check origin is explained on the Genuine products page.

Where do I get the TDS and SDS for CPI-4628-100?

Fill in the "Get documents by email" form on this page: the manufacturer's TDS (English) is sent automatically. The SDS, CO, CQ and the batch CoA are sent by an engineer within 24 working hours; the SDS also accompanies every delivery.

Can I trial CPI-4628-100 before switching the whole plant?

Yes. Hop Tien proposes changing over one refrigeration compressor, logging monthly oil top-up, discharge temperature and the condition of oil drained at low points, with an oil sample analyzed at 500 hours so the plant decides on data; Hop Tien technicians guide draining the old oil and cleaning the filter and separator.
