VariFlow Gen4 High-Pressure Coolant System
Product Info
Next Generation Coolant System
VariFlow Gen4 is Hennig's advanced high-pressure coolant system, designed to redefine efficiency and performance in machining operations. Engineered with Adaptive Flow Control, it dynamically adjusts coolant flow to deliver precise pressure settings while minimizing energy consumption, reducing coolant foaming, and decreasing heat generation. Its compact, economical design integrates seamlessly into your workflow, offering premium performance comparable to competitors' high-end models.
The VariFlow Gen4 is equipped with user-friendly features, including an HMI for pressure settings and IoT connectivity for monitoring system performance. It also includes a 25-gallon reservoir with a built-in 10-micron filter, ensuring clean, uninterrupted coolant flow. Caster wheels add mobility, allowing easy relocation between machines, while the direct-drive pump ensures smooth, quiet operation without belts or external pumps. VariFlow Gen4 delivers unmatched productivity and reliability, making it an essential addition to modern machining environments.
