Product Introduction
WB-M Series VFD High Pressure Coolant System (70Bar / 140Bar)
The WULI WB-M Series is a premium VFD High Pressure Coolant (HPC) system engineered for high-demand CNC machining. Designed and 100% manufactured in Taiwan, it utilizes low-vibration ceramic plunger pumps to deliver ultra-stable pressure outputs of 70Bar and 140Bar (1,000 / 2,000 PSI). Powered by Smart Variable Frequency Drive (VFD) technology and controlled via an intuitive 7-inch touch HMI screen, the system dynamically modulates motor output based on tool orifice size and real-time flow demand. This eliminates energy waste—slashing power consumption by 50% to 76%. Its innovative "Zero-Bypass Thermal Control" and auto-depressurization mechanism prevent coolant overheating, minimizing thermal distortion on workpieces to ensure micron-level machining precision.
- 70Bar & 140Bar Dual Pressure Options: Penetrates the steam barrier at the cutting edge for instant chip evacuation and effective thermal suppression.
- Proven 76% Energy Savings: VFD dynamically scales power based on tool coolant channels, dramatically cutting operational power costs.
- Zero-Bypass Thermal Control: Prevents excess coolant bypass from returning to the tank, eliminating heat accumulation and thermal expansion.
- 100% Taiwan-Made Ceramic Plunger Pump: Heavy-duty industrial seals with low-vibration engineering deliver whisper-quiet operation (<80dB) and extended service life.
- 7-Inch Touch HMI & Multi-Channel Control: Supports 1 to 4 customizable flow channels and multi-tool pressure presets, integrating seamlessly with host CNC controls.
- Oil & Water-Soluble Compatible: Maintains consistent pressure across all coolant types; features zero-drip tool changes and automatic shutoff depressurization.
VFD Energy Saving Performance (70Bar Field Test Data)
Conventional fixed-speed coolant systems (e.g., WB-1830M) continuously run at full motor capacity (6.1 HP) regardless of tool orifice sizes or actual flow demands, causing massive energy waste and fluid overheating. The WULI WB-M Smart VFD System smoothly adjusts motor output (1.40 HP to 6.13 HP) according to actual flow requirements (8 to 35 L/min), ensuring maximum efficiency:
| Machining Flow Demand | Fixed-Speed Model | WULI Smart VFD Model | Energy Savings |
|---|---|---|---|
| Low Flow Demand (8 L/min | Single 2mm Nozzle) |
6.1 HP (4.6 kW) (Est. US$2,202 / Year) |
1.4 HP (1.1 kW) (Est. US$527 / Year) |
76% Energy Savings |
| Medium Flow Demand (17 L/min | Dual 2mm Nozzle) |
6.1 HP (4.5 kW) (Est. US$2,202 / Year) |
2.8 HP (2.1 kW) (Est. US$1,005 / Year) |
54% Energy Savings |
WB-M Series Selection Guide
Selecting the optimal High Pressure Coolant system depends primarily on Workpiece Material Hardness and Tool Coolant Channel Cross-Section (Flow Requirement):
Step 1: Select Pressure Rating (70Bar vs 140Bar)
- 70Bar Series (WB-2030M / 2040M): Recommended for carbon steel, aluminum alloys, cast iron, structural steel, medium-deep hole drilling, and standard VMC/HMC operations. Covers over 80% of standard precision applications.
- 140Bar Series (WB-2230M / 2240M): Engineered for heat-resistant superalloys (Inconel, Titanium alloys, Stainless Steel), extreme aspect-ratio gundrilling, or high-speed turning demanding extreme jet-impact force for immediate chip breaking.
Step 2: Select Flow Capacity (34 L/min vs 41 L/min)
- Standard Flow 34 L/min (2030M / 2230M): Suitable for small-to-medium coolant-thru tooling, single-tool internal cooling, or single-channel setups.
- High Flow 41 L/min (2040M / 2240M): Designed for large coolant orifices, multi-turret simultaneous coolant supply, multiple orifices, or high-volume material removal.
| Model | Pressure | Max Flow | Motor Power | Best Application |
|---|---|---|---|---|
| WB-2030M | 70 Bar | 34 L/min | 7.5 HP | General Purpose: Steel, aluminum deep hole drilling, and standard machining centers. |
| WB-2040M | 70 Bar | 41 L/min | 7.5 HP | High Flow: Large coolant channels, multi-orifice tooling, or multi-channel turn-mill centers. |
| WB-2230M | 140 Bar | 34 L/min | 15 HP | Ultra-High Pressure: Titanium, Inconel, aerospace alloys, and extreme gundrilling. |
| WB-2240M | 140 Bar | 41 L/min | 15 HP | Flagship Heavy-Duty: High-demand metalworking requiring maximum pressure and flow. |
