We develop and manufacture products based on customer needs including hot fluid and gas transfer, freezing prevention and high-pressure specifications.
This field checklist explains how to troubleshoot temperature faults on a JINGCHENG electrically heated hose before replacing the assembly. It shows how to read the model code (for example JCH-200-16-B-3X220-P2-8) and match the sensor to the controller—Type J or Type K thermocouple, Ni120, PT100 (two-wire or three-wire) or PT1000. It then covers pin-table and connector checks, voltage and power (including PID controllers with SSR or thyristor output, and 2- or 3-channel control boxes), and installation mistakes that look like control failures: lateral twist, tight bends, cold routing and damaged jackets. A final eight-step checklist lists what to send with an inquiry.
PUR (polyurethane reactive) hot melt adhesives are rapidly replacing conventional hot melts in woodworking, packaging, electronics, and automotive assembly—but they demand more from the delivery hose. Running at higher temperatures and extremely sensitive to fluctuation, PUR requires heated hoses with precise ±1–2°C end-to-end control, non-stick PTFE inner tubes, fast heat-up, and properly rated fittings. This article explains what makes PUR harder on hoses, what a PUR-ready hose needs, and why upgrading adhesive means upgrading your hose. We offer customizable electrically heated hoses and temperature controllers—share your adhesive datasheet for a tailored recommendation.
