Provides 7 cubic feet of work space at temperatures to 350°F. Includes two (2) removable nickel plated wire shelves easily adjustable on 2" centers. Holds a maximum of seven (7) shelves. Widely used for drying small items, preheating plastics, drying powdered metals and curing potting compounds. Double doors for easy loading of large parts.
Similar to Model NB-350. Also includes two (2) shelves and will hold a maximum of seven (7) shelves. Provides over 5 cubic feet of work space at temperatures to 550°F. Ideal for high temperature processes such as annealing springs and plated parts.
Specially designed for processing and drying of plastic granules, powdered metal parts and other small parts that must be separated. Eight (8) individual 304 stainless steel drawers keep parts separated and allow individual inspection or removal without opening conventional doors. This reduces heat loss and prevents process interruption. Temperatures to 350°F. Standard drawers have 3/4" diameter perforations on 1 1/4" staggered centers on bottom and sides. Solid drawers also available.

- 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 Systems
Calibrated main temperature controller regulates desired oven temperature. Independent manual reset excess temperature interlock protects against failure of main temperature controller. On-off switch located on panel controls electrical power to oven. Red pilot light indicates heater operation.
- Additional Shelves, 20 lbs distributed load per shelf, 40 lbs maximum oven load, specify oven model when ordering.
- Dial Thermometer 10-290°C, 50-550°F dual scale range
- Digital Indicating Temperature Controller, microprocessor based, thermocouple actuated, in lieu of standard controller.
- Digital Timing Temperature Controller, microprocessor based, digital indicating, incorporates 99 hour 59 minute timer. Starts timing when temperature reaches set point and shuts down oven heat at end of set time.
- Programmable Temperature Controller, microprocessor based, digital indicating, thermocouple actuated, in lieu of standard controller.
- Recording Thermometer, thermocouple actuated, 24-hour, 10" diameter circular chart requires optional Digital Controller DIG1, DTS1 or PTC1 (side mounted).
- Adjustable Excess Temperature Interlock, thermocouple actuated, manual reset.
- Solid State Relay, in lieu of standard contacter.
- Shut Down Timer, with continuous "hold" feature
- 60 minute range.
- 12 hour range.
- Set of Eight (8) 304 Stainless Steel Drying Pans, 11 1/2" W x 20" D x 2" H (NB Models only, requires two (2) add'l shelves).
