About Kaiyuan — Refrigeration Controller Manufacturer

Our Story

Engineering Reliability Since Day One

Kaiyuan Electronic Technology Co., Ltd. is based in Quzhou, Zhejiang Province — a major manufacturing hub in eastern China. We focus exclusively on the design and production of digital temperature controllers for commercial refrigeration equipment.

Our team combines embedded systems engineering, hardware design, and refrigeration domain knowledge to deliver controllers that perform reliably in demanding commercial environments — from supermarket display cases to industrial cold storage.

We serve OEM manufacturers, refrigeration equipment distributors, and engineering companies across India, Southeast Asia, the Middle East, Africa, and Europe, with English-speaking technical support and flexible OEM/ODM capabilities.
