Microtherm Series 1550 Furnace System 16x16

includes Furnace with built in Power Supply and Control System plus Over-temperature Alarm

MELLEN recommends that the maximum operating temperature of the furnace by 50^oC to 100^oC below the maximum rating to prolong element life.

The furnace is designed for horizontal operation.  (MELLEN recommends that the maximum operating temperature of the furnace by 50^oC to 100^oC below the maximum rating to prolong element life. )

ELEMENTS:  The furnace utilizes hanging helical Silicon Carbide elements capable of 1650^o C element temperature.  The layout has been engineered for that the elements radiate directly to the work charge.  In addition to the element design, the element placement works to increase element life.

INSULATION:  The insulation for the furnace consists of an insulation package with 4" wall thickness.  The furnace roof (3"thick)  is comprised of multi-layered high temperature insulation.   Element support comes from a ceramic layer on the top of the furnace rather than the furnace roof for structural stability.  This designs prevents the elements from "falling in", due to insulation cracking, as well as removes stresses of the element weigh on the roof.

FURNACE SHELL:  The furnace has a double wall shell separated by a fan cooled air space to facilitate lead cooling  and provide a cooler exterior.  The shell is comprised of 1/16" thick sheet metal.

All MELLEN Box furnaces are furnished with a double-pivoting insulated door to keep the "hot face" safely away from the operator.

CONTROLLER:  The Microtherm furnace includes an integral digital temperature control system featuring 126 segments and 31 programs.  One "B" type thermocouple is located in the upper half for temperature feedback.  A circuit breaker is provided on the front of the unit.

OVER-TEMPERATURE ALARM: One over-temperature alarm (O.T.) utilizing an independent digitally indicating, digital set-point "hi-limit alarm" controller.  The O.T. Alarm package is furnished with appropriate thermocouple, T/C extension wire and sufficient mechanical power connector to interrupt power to the furnace in the event of an over-temperature condition at the location of the sensor.  The O.T. alarm is mounted in the main temperature controller enclosure.
