WBL/WDB Boiler Controllers

Walchem offers four different Boiler Water Controllers and Condensate Monitors.  The WBL Series controls conductivity blowdown/chemical feed for one boiler and the WDB Series controls two boilers within 500 feet of each other. 

Walchem's WBL Series controllers keep boiler water at the correct conductivity by automatically blowing down water at high solids levels and adding low conductivity make-up water.

Simultaneous control of chemical feed inhibits corrosion, solids precipitation and scale build-up. Intermittent sampling is available to facilitate inexpensive operating costs on small boilers.

The WBL controller features four methods of chemical feed via the program menu. The WBL300 is a lower cost controller with one feed/alarm output. The WBL310 has four feed/alarm outputs, giving the ultimate flexibility for your chemical feed program.

The WCM Series Condensate Monitors control the conductivity of a boiler's condensate. When conductivity of the condensate exceeds an operator-adjustable set point, the unit initiates the opening of a diverter valve to prevent contaminated condensate from returning to the boiler or sets off an alarm, or both.

WBL boiler controller and WCM condensate monitors are low cost, microprocessor-based, menu-driven industrial controllers. Exceptionally versatile, WBL, and WCM units are easily customized on site.  UL/CSA/CE certified.
