The new BL Micro Controller Boiler Control System (left), the “brain” behind Miura’s enhanced energy management system, offers signicant advancements including many new individual monitoring points –an increase of over 60% compared to our popular XJ1 Controller. The BL Controller provides robust 24/7 boiler Monitoring, Measuring & Verication (MM&V) capabilities and enhances troubleshooting by identifying problems and suggesting solutions via an easy-to-read display that interfaces with Miura Online Maintenance® software. Information is accessible both on site and on-line. The BL Controller features simple, intuitive programming that is easy to set up, program and operate. When combined with our O&M training program, the easy-to-use interface provides your facility with an intelligent boiler system to optimize energy and personnel management for increased productivity, efciency and a reduced environmental impact.

Now you can enjoy the exibility of switching fuel, without the need for a separate burner, typically required by other manufacturers. Miura technology means outstanding innovation and ease of use. Reduced Boiler Footprint Miura’s unique compact modular design utilizes a low volume pressure vessel offering output capacities comparable to much larger conventional boilers. The resulting reduced boiler footprint provides design exibility, reduced construction costs and enhanced utilization of existing space. Built-in Online Monitoring 2 in. 3 in. 3 in. 4 in. 4 in.

Miura’s On-line Maintenance® (“MOM”) system provides a unique“sliding window” feature that records cautions / alarms in real time + 4 seconds preceding them to provide enhanced troubleshooting capability. The “MOM” system is standard with every unit and Miura offers monitoring to subscribing customers with a free 6-month trial of the service. Miura offers its ER monitoring system to those facilities that wish to integrate boiler monitoring into their on-site control system rather than subscribe to an off-site monitoring service. 12 Adjustable Pressure Transducer and Switch Liquid Volume Control Overheat Protection Note: *1 *2 *3 *4 *5 *6 *7 *8 *9 *10 *11 Electric Conductivity Type Low Water Cut Off & Thermocouple Optional EXH-SGO Series at 250 PSIG MAWP, 225 PSIG maximum operating.
