STANDARD FEATURES  Back to Top


MODEL NT-800
Provides 4.3 cubic feet of work space at temperatures to 800°F. Double doors for easy loading of large parts or baskets. Includes 304 stainless steel interior and two (2) removable nickel plated wire shelves easily adjustable on 2" centers. Holds a maximum of six (6) shelves. Widely used for medium temperature applications such as tempering and relieving hydrogen embrittlement from plated parts.

MODEL NTR-800
Identical to Model NT-800, but also includes a recirculating blower to improve temperature uniformity and reduce heat-up time of oven and parts.

MODEL NT-1000
Similar to Model NT-800, but provides temperatures to 1000°F. Includes 304 stainless steel interior and two (2) removable 304 stainless steel shelves. Ideal for high temperature processes such as preheating prior to welding or stress relief of steel springs and stampings.

MODEL NTR-1000
Same as Model NT-1000, plus recirculating blower system to improve temperature uniformity and reduce heat-up time of oven and parts.

*Requires 30 ampere service on 115 volts. †Accuracy as percent of controller span. Uniformity at 50°F below maximum
temperature. Rise Time in minutes to 50°F below maximum temperature.
Tests run with empty oven and minimum exhaust. Performance will vary with
load, exhaust rate and application. See Bulletin TC-920 for additional details.


STANDARD EQUIPMENT  Back to Top

  • Standard Electrical Characteristics
    — 115 volts, 60 Hz, 3-wire cord with plug
    — 208 volts, 1-phase, 60 Hz
    — 230 volts, 1-phase, 60 Hz
    — Other electrical characteristics available
  • Standard Temperature Control System
    Analog, thermocouple actuated, main temperature controller regulates desired oven temperature. Independent manual reset excess temperature controller, adjustable over temperature range of oven, protects against failure of main temperature controller. Separate heating element relay protects against failure of main control relay. On-off switch located on panel controls electrical power to oven. Red pilot light indicates heater operation.


    • Circulation Diagrams
    (Front View)
        
    NT Series
    Heated air rises by natural convection
    from heating element beneath drip pan at
    bottom of work space.
    		    
    NTR Series
    Air is pulled from work space by
    recirculating blower, blown by heating
    element and returned to work space
    along sides of drip pan.
