Chamber Furnaces The chamber furnace consists of an iron framework insulated with mineral wool and Superwool. The insulation is enclosed between steel sheets inside the furnace and coated sheets outside the furnace. The furnace is heated up by a heat fan unit that is placed on the furnace roof. The heat fan unit consists of an electrical motor, fan wheel, elements and air-intake. The heat fan unit heats up and recirculates the air in the furnace. The air circulates from the fan unit via air channels, towards goods inside furnace and returns to fan on the roof. The airintake on the heat fan...

Conveyor Belt Furnaces The conveyor belt furnace is built up by an iron framework and is insulated with mineral wool. The furnace is heated up by a heat fan unit that is placed on the furnace roof. The heat fan unit consists of an electrical motor, fan wheel, elements and air-intake. The conveyor belt is available in various designs like a net band made by fiber glass and Teflon or spiral belt in steel. It is also possible to transport the parts hanging by an overhead conveyor. The conveyor belt has a variable speed, can be either step or continuously feeded. The number or belts, hatches...

Car Bottom Furnaces The car bottom furnace consists of a fixed chamber and a car. The chamber is insulated with mineral wool and Superwool and on the sidewalls elements are assembled to achieve a constant temperature and for easy maintenance. Circulation fan with two motor driven dampers are assembled on the roof. There is also one motor driven damper on the roof connected to a cooling fan. The motor driven car is built up by insulating and fire resistant bricks. Between car and chamber are electrical sealings on both sides of the car which closes during heating and opens when the furnace...

Car Bottom Furnace with motor driven lifting door The furnace consists of a chamber which is built up by an iron framework and is insulated by superwool and mineralwool. Heating elements are attached to the side walls. On top of furnace two circulation fans and one cooling fan are assembled. The car bottom which consists of insulation and heat resistant bricks can be loaded with approximately 5 ton goods. Both car bottom and lifting door are motor and chain driven. They are both operated by a two-hand control. Technical specifications Heating power Max. Temperature Dimensions Laboratory...

Top Hat Furnaces The industrial furnace is used for heat treatment of steel products such as tempering, annealing, soft annealing, normalising, stress relieving, homogenising and recrystallization. The bottom, which is mounted on the floor, is built up by insulating and fire resistant bricks. The top hat is insulated with Superwool and mineral wool and needs to be lifted off the bottom with lifting equipment when loading and unloading. On the bottom, guiding profiles is mounted, to force the top hat to be placed correctly on the bottom. The elements are either assembled on the sidewalls or...

Gas Furnaces The furnace is build up by an iron framework and is insulated with mineral wool. The furnace is covered with steel sheets on the inside and with coated steel sheets on the outside. Natural gas burners heat up the furnace. The hot air is guided from the burners to the fan units for circulation of the air in the furnace. The furnace has fan units containing circulation fans and motor driven dampers. It is also provided with a fan unit for cooling and for removing exhaust gases. The gas heated furnace can be used for drying of welding electrodes. Technical specifications Heating...

Temporary Furnaces Steel sheets insulated with mineral wool for temporary heat treatment installations. Can be heated with gas or electric heating power. Unique solutions can be manufactured depending on the product, process and environment. The picture shows an example of a temporary oven with ø16m and 8m high. Pit Furnaces The pit furnace is used for heat treatment of steel products in inert gas atmosphere and for nitriding. Loading and unloading is made with lifting equipment. The goods are heated by electrical elements placed along the sides. The circulation fan in the furnace makes the...

Control Systems ElectroHeat can offer different temperature control systems specific for the perature controller used for Electro- Heat ovens. The controller enables to reach a predetermined set point temperature in the shortest time or with a specific ramp rate. controller used for ElectroHeat furnaces. The controller can hold 9 programs and each program can— contain 64 segments. The segments ramp down and dwell time. Furnblog X51 is an own-developed control system specially designed for industrial ovens and furnaces. Furnblog is a program controller and a temperature logger which is...
