Pit Furnaces СШО, СШЗ

Explanation markings of pit furnaces:
with protective atmosphere СШЗ - X1.X2.X3 / T or СШЗ - X4.X3 / T
with an oxidizing atmosphere СШО - X1.X2.X3 / T or СШО - X4.X3 / T  where is,    
С   – type of heating – the resistance electric furnace;
Ш   – main constructive sign – shaft-type furnace;
З (О)   – atmosphere in the working space – protective atmosphere (oxidizing atmosphere);
[X1 - width. X2- length. X3 - height] or [X4 - diameter. X3 - height] - the size of the camera in decimeters (1 dm = 100 mm);
T – nominal temperature in hundreds of °C

Control system
 

Temperature regulator ТРП-08-ТП (by default)	Electric oven operation is controlled by a digital temperature regulator type ТРП-08-ТП (by default), and ТРП-09-ТП.   Temperature regulator type ТРП-08-ТП (by default) allows You to set one-step heat treatment program.   Programmer temperature regulator type ТРП-09-ТП allows You to organize Input, Working off and Storing 5 independent programs; rise time (lowering) the temperature and time maintaining the temperature at each step (ramp function). Total of 16 steps.   All current programs and settings the device is stored in nonvolatile memory. Thermocouple brand ТХА is used as a temperature sensor. When ordering, You can set the temperature regulator with programmer (ТРП-09-ТП), which sets the heating program up to 12 temperature regimes, heating rate and the cages holding time.
Programmer temperature regulator ТРП-09-ТП

Electric furnace control system further provides:

•  Turning off the power of heaters when you open the door (physical open circuit);
•  Protection against short-circuit and longer overcurrent;
•  Protection from accidental overheating during incorrectly specified temperature;
•  electric furnace power units are managed by means of contactless semiconductor switches, that includes the maintenance of the power key and ensures quiet operation of the furnace.
