CHEMTROL® BT112 Dual Boiler Controller
Two boilers, one controller
The CHEMTROL® BT112 controls blowdown on two boilers at once, each with its own conductivity (TDS) sensor and temperature reading, and runs up to three chemical feeds – inhibitors, biocides, dispersants and more.
It calculates the Langelier Saturation Index for water balance and logs its readings automatically. Add web access to see and adjust both boilers from your computer or phone.

BT112 Installation
The BT112 is straightforward to install, as the plumbing set-up below shows. Every controller comes with a detailed installation and operation manual.
BT112 Operation
Everything is set from the front panel. The LCD screen and keypad give direct access to every menu: sensor calibration, set points, alarm levels and the feed programs.
Remote Monitoring & Control
Every CHEMTROL® programmable controller can be monitored and controlled remotely, 24/7. Log in to our web-server from any browser to see the controller’s own display, or use the CHEMTROL app for Android and Apple.
Change settings in real time, check status reports and trend graphs, and receive alerts by email or text message – for one site or many. See remote monitoring and control.
Connect the controller by Ethernet cable, Wi-Fi, or a 4G or 5G router. Find out more: web-access options.
