Model 3175 - Water Treatment Controller
Boiler Installation with Sample Hold
Features & Benefits
Features:
- 7 inch capacitive touchscreen.
- Data Logging via on-board micro SD card.
- Email notification of alarm conditions.
- Controller can be used for Cooling towers, Chill loops, Boilers, and Condensate systems
- Removable power cord and receptacles for conduit installations. Enclosure is rated NEMA 4X
- Five user configurable relays for conductivity control and chemical addition. These relays can be configured in multiple ways including scheduled feed for biocide addition.
- Two (2) water meter inputs, two drum switch inputs, conductivity input, flow switch input, 4-20 mA output, and a 4-20 mA input are all standard features.
- Designed with a single circuit board for high reliability and lower cost.
- Large open shallow enclosure for easy wiring.
- Ball valve delay feature allows accurate control of motorized ball valves.
- Easy to program, the Model 3175 Controller uses an intuitive menu and programs identical to the Lakewood 2000 Series controllers.
- Controller can be removed from a cooling tower and be placed in another type of application when used with the appropriate conductivity sensor and plumbing assembly.
Benefits:
- Modern Connectivity & Data Logging
- Responsive Touchscreen
- Simple to Configure
- Affordable
- Updated Processor
- Five (5) Relays
- No add-on options. 4-20mA output, 4-20mA input, and biocide features are standard.
