COOPERHEAT FURNACES

Low thermal mass furnaces reduce overall heat treatment costs by increasing production and improving product quality. Their special linings require less total heat input to reach operating temperatures quicker than old-style refractory lined furnaces. Therefore, the lower thermal conductivity of the linings delivers  much lower heat loss from the furnace, achieving impressive energy savings. Close temperature uniformity can be achieved using Stork Cooperheat’s advanced programmable temperature control systems with multi-zone controls.

The theory of high velocity heating is now accepted practice industry wide and Stork Cooperheat has been one of the pioneers of high velocity heating within fuel fired furnaces. The rapidly recirculating gases break down the layer of still air surrounding the object being heated and increases the heat transferred by convection. Shorter heat up times and improved temperature uniformity are the resulting benefits.

Features

• High burner discharge velocity requires no extra recirculation fans
• Close temperature uniformity throughout the furnace
• Positive furnace pressure via pressure control prevents cold air ingress and improves temperature uniformity
• Hot spots eliminated by low flame temperatures
• Fewer burners needed reducing the cost particularly in expensive burner safety systems

Financial Benefits

• Reduced energy costs using low thermal mass materials in furnace construction, ensuring energy is used to heat the load, not furnace brickwork
• Recuperative high velocity gas burners reduce power costs

Operational Benefits

• Uniform distribution of heat controls the heating cycle and heating zones providing by a fully automatic temperature programmer.
• Design and operational flexibility associated with low thermal mass furnaces
• Modular construction enables the furnace to be extended in length to cope with larger work pieces or alternatively a temporary extension for one off applications can be added. The larger furnaces use preformed panels as standard. In many instances it can be more economical to extend existing furnaces rather than replacing them
• Wide range of fuel sources which can be more economical. It is Stork Cooperheat’s philosophy to design a system around the fuel choice of the customer, or if necessary to convert existing units
