1. ELECTRICAL BOX TYPE OVEN
Purpose of use : Powder curing
Maximum temperature : 220ºC
The furnace heating system is designed as forced convection system. It
is based on the principle of pumping the oven volume air into the oven
with the help of a circulation fan and increasing the oven temperature
with the heat transfer provided by the air passing through the heating
unit.
The walls of the furnace and heating unit are made of modular sheet
metal and high density insulated panels. Air distribution ducts with
regulated flaps inside the oven ensure that the oven temperature is
homogenous at every point. The temperature control device is digital
type and provides precise adjustment of the oven temperature.
The heating unit is placed on the side, rear or top of the oven and
consists of an insulated heating chamber, heating cell with resistance
inside, circulation fan that can operate at 250ºC and maintenance
cover.
