Model 2250 Microprocessor-Based Boiler Controllers

Discontinued Model

Microprocessor,Based,Boiler Controller,Model 2250,Lakewood,InstrumentsLONWORKS is the latest in microprocessor technology that gives the user the highest level of application flexibilty. A large graphic screen, multiple inputs and very easy setup, with easy field upgrade characterize this new technology.

Features

  • Steam flashing detector and compensation.

  • Sample/cycle or continuous conductivity control of blowdown.

  • Use sample/cycle for blowdown less than 1,000 lb./hr.

  • Use continuous for blowdown greater than 1,000 lb./hr.

  • Can feed chemical according to water meter percent of bleed or percent on-time.

  • Interactive communications software datalog and control (-RS2L & -RTC Options).

  • Four different languages.

English Spanish (standard)
English French (optional)
English German (optional)

Benefits
  • Accurate control of boiler conductivity.

  • Control results in fuel savings by preventing excessive blowdown.

  • Prevents carryover due to excessive conductivity.

  • Two water/flowmeter inputs provided.
