Synthetic heat transfer fluid based on partially hydrogenated terphenyl for closed-loop liquid-phase heating systems, bulk fluid up to 357 °C and film up to 375 °C; according to PARATHERM documentation, it shares the same chemistry with, and is compatible with, the terphenyl fluids commonly used in thermal oil heaters, so it is an option for systems currently running this type of fluid.

208 L drum
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 heater type, operating temperature and the fluid currently used so an engineer can confirm the right product.
Hop Tien is the authorized distributor of Lubrizol Fluid Engineering (PARATHERM 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.
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.
Yes, but not as a one-machine trial: a heat transfer system is one closed loop. Hop Tien samples and analyzes the fluid in use, then proposes a top-up or partial replacement with before-and-after data so the plant decides on data.
