“A low-cost upgrade for obsolete CB-Hawk systems” Preferred Instruments CB-Hawk Replacement System Based on BurnerMate TS Technology

Known as Honeywell BC-7700 and Cleaver-Brooks Hawk systems, thousands of units have been installed since the early 90’s. Honeywell abruptly stopped manufacturing system components and spare parts over a year ago. The History.

The Problem  CB has literally thousands of systems installed with very limited repair parts--many already gone.  CB’s answer is a very expensive PLC-based upgrade costing $17K-$40K plus installation.  Alternatively, C-B will convert the Hawk system to an RM-7800 for $7,000 (and lose all the functions of the Hawk system)

Preferred’s Solution Introduced in 2005, the BurnerMate TS consists of:  A programmable DCS  A Honeywell flame relay  A touch-screen HMI.

Preferred’s Solution Preferred has configured a BurnerMate TS system to be a wire-for-wire replacement for the CB Hawk system.  Replace Hawk sub-panel with Preferred sub-panel.  Replace gas & oil pressure sensors with pressure switches. Installation is as simple as…

Preferred’s Solution Preferred has configured a BurnerMate TS system to be a wire-for-wire replacement for the CB Hawk system.  Replace steam pressure sensor with a pressure transmitter. (or temp. transmitter for hot water boilers)  Replace mod motor with Preferred SM-15 servo actuator

Preferred’s Solution Preferred has configured a BurnerMate TS system to be a wire-for-wire replacement for the CB Hawk system.  Remove CB Hawk keypad.  Install the Preferred touch- screen display. Blockware is pre-programmed. Commissioning is as easy as filling- in-the-blanks.

Preferred’s Solution Preferred has configured a BurnerMate TS system to be a wire-for-wire replacement for the CB Hawk system.  Existing control panel, entrance box, control switches, flame scanner, and operating limits are re-used.  Existing solid state gas and oil pressure sensors can be re-used for monitoring purposes. But don’t! They will fail eventually too and replacement parts are unavailable.

Easy Set-Up Fill-in-the-blanks on factory-configured screens.

 The screen pages closely resemble the language and logic of the old Hawk systems.  “Fill-in-the-Blanks” commissioning.  Operators should not be intimidated and won’t have to “re-learn.”

Retrofit Advantages  Lowest cost, full function replacement  Easiest Conversion  Technology proven in thousands of PCC-III and DCS-III installations  Lowest install time

Product Improvements  Touch-screen is easier to use.  DCS-III is configurable for future upgrades.  PV inputs are standard, non-proprietary.  Gas and oil switches are standard, non- proprietary.  10” touch-screens are available  NFPA compliant  U.L. 508 compliant

Product Improvements  Ethernet IP-Standard  Modbus-Standard  Remote monitoring through standard web browser. The BurnerMate TS can communicate with building management systems, energy management systems, or a DCS via open protocols including:

Cost Competitive  Material cost is under $15,000.  Product is packaged for easy installation in existing Hawk enclosures. This makes for a less expensive project than CB’s upgrade options.

Support  Proven BurnerMate Technology.  Fewer proprietary parts.  Industry-standard communications.  Software is pre-programmed for simplicity, but can easily be expanded for more functionality.  Rep and factory support available.  Free factory training is available.
