Miura Boiler - Low NOx Industrial Steam Boilers, Commercial Boilers, Steam Generators, Hot Water Boilers

Split Flow

Quality brine is supplied throughout
the entire resin layer so ideal
regeneration is performed every cycle

Conventional Parallel Water Flow
(while regenerating)

As brine circulates from top to bottom,
it absorbs the hardness released from
the resin, but does not fully regenerate
the bottom portion of the layer.

Boiler Operation

The MW will automatically engage a 24 hour regeneration for each tank in the event the integral water totalizer is compromised. (Connection from a makeup water solenoid valve is required).

If Colormetry detects hardness leakage, it sends a signal to the boiler's hardness alarm contactor, and will automatically switch tanks to continue to supply softened water. The control system interfaces with the boiler controller to initiate automatic blowdown after receiving hardness alarms.

Monitoring the brine flow rate with a flow meter at the brine input line, the MW prevents hardness leakage by managing regeneration of the brine amount and detecting brine introduction failure.

A brine concentration sensor monitors the specific gravity of the brine, detecting the status of the regenerating salt and preventing regeneration failure in the event the tank is allowed to run empty.

Colormetry* (CMU-224H Hardness)

Water hardness is a common cause of boiler damage. Typically, water-hardness levels are checked manually through the use of chemical reagents. Such measurements are timeconsuming and can result in incorrect readings.

Colormetry solves all these problems by offering automated reagent injection, mixing and evaluation integrated into the boiler control system.

• Automatically monitors water quality
• Controls MW regeneration if hardness is detected
• Alarm and fault history logging
• One-touch reagent replacement
• Compact design

The MW system is fully compatible with Miura's PC dashboard monitoring systems, as well as third-party PLC integration (Modbus & BACnet), to further enhance oversight of softener performance. Integrating the softener system into the comprehensive boiler controls/ monitoring system maximizes operational awareness and provides real-time boiler water quality management, acknowledging its role in supporting overall system optimization.

Note 1: This is the pressure loss during normal operation. (With water flowing through one unit and other unit on standby, at standard flow rate, with a water temperature of 68°F.)
Note 2: This is the amount of salt per regeneration; settings are changeable.
Note 3: This value expresses hardness removal capacity per unit, which increases and decreases depending on the set amount of regeneration salt.
Note 4: Minimum pressure is the water pressure required for regeneration; maximum pressure is the maximum allowable water pressure of the unit.
Note 5: This is the value for the specified pressure range when the amount of regenerating salt is set to default.
Note 6: This is the value for the specified pressure range.
Note 7: This is the value per unit.
Note 8: This is the value per unit.
