Laboratory Stirring Systems & Precision Stir Testers |
G. K. Heller stirrers offer a wide range of features and capabilities including:
- Feedback circuitry on all models to maintain speed even when viscosity changes
- Standard horsepower ratings from 1/40 to 1/4 horsepower, 50/60 Hz operation
- A selection of propellers & paddles from 1-1/2" to 6" diameter
- Reference circuitry maintains speed even with voltage fluctuations of ±10%
- Cord connections between drive motors & controls increase convenience & allow placement away from hostile environments
- Stirrers filter the drive current for better performance. This filtering process:
- Eliminates the objectionable pulsing action common to unfiltered DC current
- Reduces motor heating
- Allows the use of a smaller motor for the same power rating
- Ensures smooth rotation for precise stirring
- Lengthens motor brush life
- Prevents demagnetization of permanent-magnet motor fields

Stirring Systems
GT31 Stirring System - A favorite with chemists and lab technicians everywhere. Totally enclosed, 1/40 hp, permanent magnet motor with two output shafts for maximum speeds of 4,000 and 333 rpm. The armature shaft provides high speeds for mixing light materials, while the geared shaft generates 3.6 lb. - in. (4.2 kg-cm) of torque at slower speeds for stirring more viscous mixtures. Continuously variable speed control. |
 |
| GT24 Stirring System - Combines today's permanent-magnet motor technology with solid state electronics. Totally enclosed, 1/17 hp, cool, and quiet-running motors with direct-drive and geared options. Models available with speeds up to 2,500 rpm and torques up to 12 lb. - in. (13.8 kg-cm). Continuously variable speed control. |
