Key Features
◆ Integrated Smart Touchscreen
Equipped with a 10-inch LCD touchscreen that integrates temperature control, timing, and pressure regulation. Replaces conventional separate controllers and timers for a cleaner, more intuitive user interface.
◆ Extended Automatic Liquid Replenishment
The built-on automatic refill system allows up to 1064 hours of continuous testing without manual liquid addition – ideal for long-duration runs and reducing human intervention errors.
◆ Low-Noise Direct Drive
The motor and pump are now directly coupled, eliminating the traditional belt drive. This design significantly lowers operational noise and avoids performance degradation caused by belt wear, ensuring greater long-term stability.
◆ Durable Pump with Steady Flow
A newly designed pump delivers stable flow rates strictly within the required range (1.3–1.6 L/s). Enhanced durability reduces the frequency of pump replacement and lowers maintenance costs.
◆ One-Key Automatic Sampling
Simply prepare the sample and press one button to start automatic sampling. The system stops automatically once the required volume is reached – no additional steps needed.
◆ Flexible Draining Option
After the test, users can choose between manual or automatic liquid drainage to suit different laboratory workflows.
◆ Fully Automatic Pressure Control
Integrated pressure maintaining and relief system controls the pressure between 85 and 95 kPa. When pressure drops below 85 kPa, the system automatically pressurizes to 85 kPa; when it exceeds 95 kPa, the relief valve activates until pressure falls below 95 kPa. No manual adjustment is required, ensuring precise and stable pressure throughout the test.
Applications
The DFYF-902 is ideal for coolant manufacturers, third-party testing laboratories, research institutes, and automotive parts labs. By simulating long-term corrosion under dynamic high-temperature, constant pressure, and circulating flow conditions, it accurately evaluates the corrosive effect of coolants on metal coupons, providing scientific support for product improvement and standard compliance verification.
