Standard Temperature Control Systems
  • MODELS LO-201C AND LW-201C
    Bimetal control thermostat sets desired oven temperature. Thermal cutoff limits maximum oven temperature. Red pilot light indicates heater operation. Top mounted mercury thermometer.
     
  • MODEL LR271C
    Primary hydraulic control thermostat sets desired oven temperature. Second manual reset hydraulic thermostat limits maximum oven temperature. Red pilot light indicates heater operation. Top mounted mercury thermometer.
Gravity Convection
  • ALL MODELS
    Heat is transferred from the bottom up through the oven chamber by natural convection and exits through vents in the oven top. Adjustable fresh air inlet damper at the oven bottom provides control of the amount of fresh air entering the oven.
