Safety Drives The Industry
Boiler manufacturers throughout the world have been
striving for years to provide safe and reliable equipment.
Adhering to rigid construction standards such as ASME,
UL, CSD-1, NFPA, cUL, etc., the safety in boiler design
has made significant strides as they go about satisfying a
plethora of needs from comfort heating to an assortment
of process applications.
Much of the increased safety over the last 20 years, has
been a direct result of boiler manufacturers incorporating
some of the advances in control technology into their operating
systems. Microprocessors and solid state based componentry
have proven to be extremely effective and reliable
replacements to the old electro-mechanical controls which
were prevalent for so many years. The additional benefits
offered by this type of technology in addition to enhanced
safety, is the ability of the device to self check itself to assure
its operating properly, enhanced security through password
protection, communication either locally or remotely, diagnostic
checking and logging of alarm history, just to name
a few.
The primary control on the boiler; however, which has been
mostly overlooked when it comes to incorporating state of
the art technology, is the low water cutoff.
New Technologies Enhance Safety
Cleaver-Brooks, knowing this was a vulnerable area, and
wanting to provide the safest boiler possible to its thousands
of valued customers, decided to take direct action.
The basis of design called for use of a microprocessor based
control system which embraced six (6) important design criteria:
Simplicity, Safety, Security, Dependability, Adaptability
and Environment. The result is the revolutionary C-B Level
Master low water cutoff and pump control using the proven magnetostrictive
technology (used for many years in various
industries for measuring level and distance relationships) in
conjunction with a solid state sensor and microprocessor
based controller. Simply, the safest control on the market
today.
C-B Level Master offers 6 key features for keeping your boiler operation as safe and reliable as possible
Simplicity
- Magnetostrictive technology eliminating levers and switches
- Non contact and non wearing titanium float
- User friendly controller with easy to read parameters/alarms
- Uses single phase power to a central connection point
- Can be used for on/off pump operation or modulating feed
Safety
- Column blowdown reminders and message it's been done properly or improperly
- System allows for checking the auxiliary low water cutoff and its proper operation
- Float movement is constantly checked; stuck float shuts boiler down
- Electrics and microprocessor circuits checked several times per second for continuity and performance
- Low water shutdown and alarming
- High and low water warnings
- Alarm and blowdown history logging with time and date stamps
Security
- Password protected regarding level settings and alarm and blowdown history files
- On going level indication; easy to see and read exactly
Dependability
- Alarm and blowdown history logging
- Blowdown reminders
- Constant checking of electrics/electronics
- Remote communication access (RS-232)
Adaptability
- Direct replacement and retrofittable to all makes of boilers
- On/off or modulating boiler feed control with same unit
Environment
- C-B Level Master eliminates the mercury!
The C-B Level Master. Simply, the safest control on the market today.
