Speed Regulators

Speed Regulators

Speed Regulators are precision control devices used to manually or electronically adjust the rotational speed (RPM) of stirrer drives, agitators, and mixing systems. They provide stable and repeatable speed control for laboratory, pilot-scale, and industrial glass reactor applications where simple, reliable, and cost-effective control is required without full VFD complexity.

Key Features & Benefits

• Smooth and stepless RPM adjustment
• Stable speed under varying load conditions
• User-friendly operation with rotary knob or digital interface
• Compact and robust construction
• Low maintenance & high reliability
• Cost-effective alternative to VFDs for fixed-torque applications
• Improves mixing consistency and process repeatability

Types of Speed Regulators

• Electronic Speed Regulators
• Analog Potentiometer-Based Controllers
• Digital Speed Regulators with RPM Display
• Panel-mounted & stand-alone units
