Boiler Blowdown Control System – Model 61
The Model 61 Automatic Boiler Blowdown Control System from ECD provides a reliable solution for the continuous control of the surface blowdown rate for commercial and industrial boilers. The Model 61 Boiler Blowdown Control System is a rack-mount, plug-and-play system, which is easy to set-up, simple to operate and provides cost-savings over manual blowdown. The modular design of the BBS includes a 316 stainless steel sediment trap and sample cooler, temperature gauge, sample control valve and safety relief valve. The Model 61 sample cooler reduces water temperature prior to sample measurement. By cooling the sample, the accuracy and reliability of the conductivity (TDS) measurement is improved.
The conductivity measurement is made with the Model C22 controller and the ECD Model CS10 conductivity sensor or the Model T80 Universal transmitter with the S80 conductivity sensor. The Model C22 is a line powered instrument, 110/220 VAC or 24 VDC, with PID control functions, logic functions and timers and is supplied with one 4-20 mA output and two alarm relays in it’s standard configuration, up to (3) 4-20 mA outputs and (4) relays are optionally available. The Model T80 transmitter is supplied with (1) 4-20 mA output, MODBUS RTU and (3) relays, HART 7 is optionally available.
The Model 61 Boiler Blowdown Control System is a rack mounted modular design that includes: a 316 SS sediment trap, 316 SS sample cooler, temperature gauge, sample control valve and safety relief valve, all tubing and fittings are 316 SS. All system components, except the jacket of the sample cooler system, can be supplied in carbon steel. The Model 61 is optionally available in a NEMA 4 enclosure.
