VINAFEED Group is a leading livestock feedproducer in Vietnam, known throughout the country for its two flagship brands, Vina and Happy. Over the years, the company has expanded into a network of modern pig farms, each designed to uphold the highest standards of animal welfare and production efficiency. At the heart of this network is the state-of-the-art Vina Farm – Tay Ninh 1 facility, a symbol of VINAFEED’s dedication to durability, operational stability, and smart, cost-effective farming solutions.
Before turning to dol-sensors, VINAFEED relied on a major controller brand and used their humidity sensors. But inside the demanding environment of a pig farm—thick with moisture, dust, and corrosive gases—those sensors often couldn’t endure. Failures became common, each one interrupting operations, straining maintenance schedules, and adding unnecessary cost. Replacement parts took too long to arrive, leaving teams waiting and production vulnerable.
The turning point came when VINAFEED adopted the DOL 104 humidity sensor (0–3 VDC). Built with IP67 water protection, the sensor was designed to thrive where others faltered. Its durability promised consistency; its pricing made it a smarter investment; and its rapid availability ensured the farms would no longer be held hostage by long lead times. For VINAFEED, the DOL 104 was more than a sensor—it was a solution built for real-world farm conditions.
Once the DOL 104 sensors were installed, the difference was immediate and unmistakable. Failures dropped dramatically, and the sensors ran reliably for extended periods, cutting both downtime and maintenance costs. With replacement units consistently in stock, the technical team regained control over their workflow. They now rely on the stable performance and effortless integration of the DOL 104, confident that the system supporting their farms is as dependable as the livestock they raise.
