Chemtrak Jr.

4-Washer, 8-Product Laundry Chemical Allocation System
Up to 250 lb. (114 kg.)

Chem-Trak Jr is an advanced yet simple chemical dispensing system designed to service up to four washers with capacities up to 250 lbs (114 kg). Washers are accurately and automatically dosed with up to eight chemicals through a single chemical and water flush line at flow rates up to 36 oz/min (1065 mL/min). A central microprocessor control receives each chemical request from the washers and reliably manages the specific chemical volume delivered to the load. Smaller laundry facilities can now realize the same benefits of many large plants including:

  • Centralized chemical storage
  • One dispenser on the wall
  • Fewer chemical delivery lines
  • Rapid chemical dispensing with flush
  • Data management reports in plain text and Excel formats
  • 90 Formula capability
  • Simple programming w/menu-driven display
  • Simple user Interface w/formula indicator

  • Detailed data management reports
  • Integrated chemical flush manifold
  • Low voltage controls
  • Network to other Knight dispensers
  • Reliable Knight peristaltic pumps
  • Load weight entry
