TYPE FB FURNACES 



110-220-440 VOLTS 



Hoskins Type FB Electric Furnaces are for work requiring temperatures up to 

 1100 C. (2000 F.). They are especially adapted to heavy duty or continuous operation, 

 and are capable of twenty-four-hour-per-day service if required. The heating units of 

 all Type FB Furnaces can be removed and replaced by the operator within a few 

 minutes. 



Temperature The maximum working temperature of all Type FB Furnaces is 

 1100 C. (2000 F.). The minimum temperature at which the rheostat-controlled fur- 

 naces can be maintained (after having come up to heat) varies between 316 C. (600 F.) 

 and 536 C. (1000 F.) for the different designs. The Types FB 204 to 235 inclusive can 

 be maintained at any temperature between that of the room, in which the furnace is 

 operating, and 1100 C. (2000 F.). 



Operation Type FB Furnaces operate on low voltages (10 to 67.5 volts), for 

 which reason they are best adapted for use on alternating current circuits in connection 

 with a transformer. They are regularly supplied for use on 110, 220 or 440 volt, 25 or 60 

 cycle lines, but can be supplied for other voltages and cycles at prices which will be 

 quoted on application. Temperature regulation of the Types FB 204 to 235, inclusive, 

 is by means of regulating transformers; the types of smaller power in-put are con- 

 trolled by means of rheostats. 



Power Consumption None of the furnaces described in this bulletin, of course, 

 draws the full load except when heating up. Once up to heat, they operate on a greatly 

 reduced current, in some cases less than half the maximum.
