CMB Low Pressure Steam Generator­ Delivers 9 to 45 lbs. of steam per hour at 0 - 90 psig, and is used in many manufactur­ ing processes. The CMB's small size and small capacity make it an ideal "point of use" steam source in industrial plants, computer rooms, laboratories, hospitals, jewelry stores, steam rooms and other spot heating applica­ tions. The CMB is also ideal for stand-by operations which require small amounts of steam or humidification during off season periods when the main plant boiler may be shut down.

Advantages

The metal sheath isolates and protects the resistor wire from the environment. At the same time it maximizes heat transfer capability to the work. Fintu be® elements can be bent to put the heat where it works best. Fi ns greatly increase surface area and permit faster heat transfer to the air, resulting in lower element surface temperatures. High watt density permits use of fewer elements and a higher concentration of installed kW for a given area.

Fin tube~ heaters are ideal for both comfort and industrial process air applications.

Electrical Table for ADH and ADHT Duct heaters For selecting the proper control panel for use with . ~~ro I Circuits the ADH and ADHT duct heaters, the number of cir­ cuits is of crucial importance. The Electrical tabl e, at 1 right, should be used for the purpose of determining the number of circuits in the panel. 1 1 Field Wiring- Refer to Graph ADHTB Terminal 1 Box Temperature field wiring selection guide in the ~ 1 technical section of this catalog (Section 1).

Gas tight construction should be considered if the gas pressure in the duct is at a higher relative pres­ sure than in the terminal box which is at room air pressure. Refer to ADH/ADHT terminal box tempera­ ture and field wiring selection guide showing the temperatu re in the terminal box at various gas outlet 4 temperatures.

Insulation Housing -Includes 3' of high tem­ perature thermal insulation to reduce duct heat conducted into terminal enclosure. Overtemperature Protection -A type K thermo­ couple is welded to the element sheath surface to sense element temperature, and is wired to a terminal block located on the outer surface of the terminal housing.
