HRI Refurbished & Demonstration Spinners



The model PWM32 Spin Controller has been upgraded and new product is now called model PWM50. We buy used equipment and factory re-furbish it at times, so the PWM32 may linger in our terminology and sales material for a considerable time. References to the PWM32 will be updated as soon as practical.

See the special page explaining the main differences in the two models.

A limited number of low cost, non-programmable, single speed/single time EC101D & EC101DT Refurbished Spinners are now available for purchase. Information on the two EC101 models available is listed below.

These low cost spinners are being sold on a first come/first served basis.

We also have a limited number of demonstrator and refurbished PWM32 controllers. Information on our PWM32 controllers can be found at http://www.headwayresearch.com/products/pwmcontrol.htm

EC101D Digital Photo Resist Spinner Series Refurbished Models

EC101D: The EC101D spinner series offers high acceleration, high torque, electronic speed regulation, automatic cycle control, and automatic braking.

The Motor Control Unit contains a full wave SCR motor drive circuitry. The unit includes a digital tachometer along with speed and timer potentiometers. The acceleration adjustment is accessible on the front panel. The digital tachometer on the front panel indicates spinner speed directly in thousands of RPM.

The EC101D spinners are supplied with a dual function footswitch. The front part of the footswitch initiates the spin cycle. The rear part stops the cycle if desired.

EC101D Bowl Arrangements:

The R790 Bowl Assembly is capable of spinning up to 5" diameter substrates. The assembly consists of a rectangular box with stainless cover and a two piece stainless bowl insert and deflector ring. An angled stainless steel catch pan with drain encircles the inner bowl. The base of the inner bowl has exhaust ports on the outside edge, which direct resist into the catch pan and airflow into the exhaust system. A plastic bowl insert and deflector are included with this assembly.

The CB15 Bowl Assembly is capable of spinning up to 9" diameter substrates. The assembly is equipped with a hinged, counterbalanced lid (interlocked electrically for closed operation only) that completely exposes the entire bowl when opened. The CB15 is designed for handling large substrates with an integral flange to permit flush mounting in a table top. Drains in the inner bowl may be connected to a waste collector or left closed for periodic dumping. Included with the assembly is plastic bowl insert and deflector.

The R485 Bowl Assembly is capable of spinning up to 3.5" diameter substrates. The bowl arrangement is designed for minimum space requirements. The spinner has a rectangular box with polished stainless steel cover, stainless bowl and fume exhaust port.

EC101D Features

High Adjustable Acceleration - The acceleration is set at the factory at approximately 600 milliseconds to 10,000 rpm. Acceleration may be easily adjusted from 200 milliseconds to 1.2 seconds. This adjustment is accessible on the front panel.

Wide Adjustable Speed Range - Standard speed is variable from approximately 50 to 10,000 rpm.

Automatic Cycle Control - In the automatic mode, the footswitch initiates a complete spin cycle. Vacuum is automatically applied; spin started and timed, brakes applied at the present time, and the vacuum released. The timer resets for the next cycle. The standard timer range is 1 to 999 seconds.

Automatic Dynamic Braking - The automatic dynamic braking system quickly stops the spinner at the end of the spin cycle. In the event of a vacuum failure, the dynamic brake will normally stop the spinner before the substrate can be thrown.

Vacuum Interlock Protection - Adjustable vacuum interlock circuit protects the operator and the substrate. If the substrate is not properly seated or if the vacuum source is inadequate, the spinner will not operate. If the vacuum drops during a spin cycle, the machine will stop. A warning buzzer indicates vacuum difficulties when the start switch is pressed.

EC101DT Digital Photo Resist Spinner Series Refurbished Models

EC101DT: The EC101DT spinner series offers high acceleration, high torque, electronic speed regulation, automatic cycle control, and automatic braking. The electronics are housed in the motor controller and the motor package is nitrogen purgable.

The Motor Control Unit contains a full wave SCR motor drive circuitry. The unit includes a digital tachometer and timer. The acceleration adjustment is accessible on the front panel. The digital cycle timer is adjustable over a time range of 1 to 999 seconds. The digital tachometer on the front panel indicates spinner speed directly in thousands of RPM.

The EC101DT spinners are supplied with a dual function footswitch. The front part of the footswitch initiates the spin cycle. The rear part stops the cycle if desired.
