Fluorescent UV dye for R-1234YF AC leak detection–(Author: sunlonge)


Modern R-1234RF air conditioning system have new requirements for fluorescent leak detection. With concerns over rising fuel costs, manufacturers are developing more efficient, environmentally friendly vehicle systems. The industry trend to smaller, more efficient vehicle systems makes it difficult to produce high-quality fluorescent leak detection dye. This is because of decreasing AC oil charges, oil/dye compatibility issues, and new refrigerant charging procedures.

Over the past few years, refrigerant systems have changed drastically. Oil charges can now be as low as 60 ml. More than ever, it is critical for OEM Grade R-1234yf AC Leak Detection Dye to be highly concentrated. If too much dye is added to the system, the AC oil viscosity could easily operate outside of the manufacturer’s specification. To avoid causing harm, R-1234yf compatible dyes should be formulated with OEM-grade R-1234yf oil, so the dye can be added safely without changing system properties.

Sunlonge’s R-1234RF AC leak detection dye meets all requirements for R-1234RF fluorescent leak detection. The dye does not affect the compressor’s oil viscosity and is designed to be as close to true R-1234YF oils as possible.

The dyes are used with inline injector and syringe injector. With Sunlonge R-1234YF AC leak detection dye, Sunlonge continues to meet the standards in the automotive industry while continuously pursuing environmentally-friendly and effective approaches to AC leak detection.
