Romanoff KWS EB 20/30: 6-Flask Industrial Vacuum Investing System
The Romanoff KWS EB 20/30 is a premier industrial investment mixing machine designed for high-capacity production without sacrificing the precision required for boutique designer studios. Engineered with a complete stainless steel casing and a high-torque 220V 3-phase motor, this system is optimized to mix up to 30 kg of powder under a full vacuum. It is specifically configured to accommodate up to 6 flanged flasks simultaneously, delivering the superior surface quality and contour sharpness that professional jewelry manufacturing demands.
Precision Vacuum Engineering
Achieve flawless molds through a synchronized mixing and pouring process that eliminates air entrapment at every stage of the investing cycle.
- 6-Flask Simultaneous Fill: Engineered to fill up to 6 flanged flasks (max 140 mm diameter) under constant vacuum and vibration.
- Pneumatic Lift System: Features a unique pneumatic lift for the mixing chamber, significantly reducing physical labor and improving cycle efficiency.
- Variable Speed Control: The drive motor allows for precise rotational speed selection, ensuring the perfect slurry consistency for every investment type.
- Bubble-Free Results: Simultaneous vacuum and vibration during the pour stage allow for the production of the highest-quality, high-density flasks.
Industrial Longevity
Constructed with premium materials to resist the corrosive nature of gypsum and water in a high-volume manufacturing environment.
- Stainless Steel Construction: The complete stainless steel casing and aluminum components result in minimum wear and tear and zero corrosion.
- Pump Protection: An integrated advanced filter system traps particulates before they reach the vacuum pump, substantially extending the pump's life cycle.
- Special Alloy Taps: Filling taps are manufactured from a proprietary alloy specifically designed to resist the corrosive effects of gypsum and water.
- Fast Maintenance: Long-lasting gaskets (2-3 year lifespan) can be replaced by loosening just two screws—no machine dismantling required.
Technical Specifications
The KWS EB 20/30 is a robust workstation designed for rapid throughput and effortless cleaning. For maintenance, the mixer swivels over a dedicated drain bowl for rinsing with an integrated spray nozzle, maintaining a clean and pleasant work environment.
Shipping & Support: This unit weighs 211 kg (uncrated) and ships via truck freight. Romanoff International provides comprehensive remote training and technical support for all KWS installations.
