MODERNIZATIONS / UPGRADES

Western States offers a wide range of modernization upgrades for existing batch and continuous centrifugals. The robust construction of the Western States centrifugal assures a life of 30 or more years. As technology advances and new innovations are incorporated into the TITAN centrifugals, Western States has created a line of modernizations that will allow the older Western States centrifugals to take advantage of the new technology. Upgrading existing Western States centrifugals will increase performance, reduce spares parts requirements, reduce maintenance, and greatly extend their life.

Modernizations for Batch Centrifugals

• The ringless basket will increase capacity by 20%
• Requires no modification to the curb
• Bolts to existing basket spindle
• Can be used with existing two speed motors with no reduction in cycle time
  Available for the
  • 48" x 30" x 7", 1200 rpm basket
  • 48" x 36" x,7", 1200 rpm basket
  • 54" 40" X 7", 1200 rpm Basket

Variable Frequency Drive

• Eliminate power spikes and reduce overall power consumption
• Active front end drive and full regenerative braking returns power to the factory grid each cycle
• Near unity power factor throughout the entire cycle
• Encoderless operation reduces complexity and increases reliability
• Eliminates the Turn-Tork slow-speed reverse drive
• TEFC motor eliminates sugar dust contamination

Electronic Loading Control

• Replaces the mechanical servo loading system
• Generates a 4 to 20 mAmp signal in response to changing sugar load to control the loading gate
• Retains the sequenced gate closing action to assure maximum loading of the basket
• Can be used with the sliding wedge or roller wedge loading gate
• Available in a paddle type (standard) or non-contact ultra-sonic type (optional) configuration

Enclosed Feeding System

• Replaces the sliding wedge and roller wedge type loading gate
• Feed control is a round butterfly valve
• Dripping is prevented by an oval butterfly valve mounted on the curb top
• Requires an electronic loading control

PLC Automation

• Replaces old relay and obsolete PLC controls
• Reduces spare parts costs
• Compatible with DCS systems
• Industry standard Allen Bradley PLC with world-wide support
• Can be configured for Modbus communication

Touch Screen Graphical Operator Interface

• Replaces mechanical pushbuttons
• Full color graphical touch screen for manual or automatic control of the centrifugal cycle.
• Set all process timers from the screen
• Control gate opening and basket fill from the screen
• Screen displays operating information throughout the cycle
• Displays diagnostic information to aid problem solving
• Requires PLC upgrade

Tork-Master Motor Controller

• Replaces the high and low-speed contactors used with the two-speed motor
• Electronically controls the application of power to the low and high-speed windings greatly reducing the wear on the contactor contacts
• Eliminates the Turn-Tork slow-speed reverse drive.

Modernizations for Continuous Centrifugals

100 HP drive motor

• Replaces the 75 HP drive motor of a CC-6A
• Increases throughput

Needle-Valve Feed System

• Replaces older style orifice plate feed system
• Changes feed rates as massecuite consistency changes without stopping the feed
• Achieves better pretreatment with the improved feed guide rod and halo steam design

Single Loop Control

• Replaces old-style PLC and relay controls
• Accurately maintains the preset operating level as massecuite levels in the mixer change
