HVAC Solutions from McDonnell & Miller:
* Boiler Controls.
STEAM BOILERS - Steam Heating Boilers are classified as boilers in closed heating systems where all condensate is returned to the boiler. Best recommendation for all automatically fired boilers is a feeder cut-off combination. It adds water as needed to maintain a safe operating level, and stands by to interrupt circuit to burner if water level drops into emergency zone. Steam Process Boilers are classified as boilers in systems where not all the condensate is returned, and some make-up water is needed. A separate feeder and separate cut-off are recommended, so operating levels can be set for the wider differential required in such service.
HOT WATER BOILERS - Best recommendation for all automatically fired boilers is a feeder cut-off combination. It adds water if needed to match the discharge capacity of the relief valve, and stands by to interrupt circuit to burner if water level drops into emergency zone.
COMBINATION Low Water Cut-Off/Pump Controllers for Steam Boilers (42S, 93, 94, 150S, 157S, 193, 194).
WATER FEEDERS - For low pressure steam boilers with cold water feed
• Slide switch allows the timing cycle to be matched to
that of the boiler size and operation
• Electronic operation provides consistent, accurate cycleto-cycle repeatability
• Universal design simplifies selection and reduces stock
• Can be used with mechanical or electronic low water cut-off controls
• Manual feed button
• Includes 3⁄8 NPT thread x 1⁄2" (13mm) tubing adapters for quick installation with 1⁄2" (13mm) copper tubing
• Easy to clean strainer
• Maximum water pressure 150 psi (10.5 kg/cm2)
• Maximum boiler pressure 15 psi (1 kg/cm2)
• Maximum water temperature 120°F (49°C)
• Maximum ambient temperature 100°F (38°C)
• Maximum power consumption (during water feed only)
– 15 VA at 24 VAC
– 20 VA at 120 VAC (50 or 60 Hz)
* Liquid Level Controls.
VALVES (Blow Down 14-B, Test-N-Check TC-4 Pressure Relief 250, 260 and Flow Switches)
CONDUCTANCE ACTUATED (General Purpose Sensors and Controls 750B, RS Sensors, 750B-C3, AS Probes)
FLOT ACTUATED PNEUMATIC
FLOT ACTUATED VALVES
* Flow Switches: The flow of liquids in pipelines plays an important role in industry and commerce. Under most circumstances it is essential to know whether or not there is a flow in a pipeline, and to act upon that knowledge. That is the reason for, and the function of, McDonnell & Miller Flow Switches.
A complete line of Liquid Flow Switches has been developed for a wide range of applications and literally
hundreds of uses, including:
• Air Conditioning
• Hot Water Space Heating Systems
• Hot Water Supply Systems
• Pump Systems
• Water Cooled Equipment
• Blending or Additive Systems
• Liquid Transfer Systems
• Fire Sprinkler Systems
• Water Treatment Systems
• Swimming Pool Chlorination
• Industrial Laser Coolant System
