Long established as the market leaders in the design and manufacture of gas fired rapid heating furnaces, Fairbank Brearley successfully applied significant knowledge and technology to increase manufacturing production in leaf, coil spring and anti-roll bar production worldwide. The expansive range to date  extends from 45kg/hr to 8.5tonne/hr. with purpose built equipment designed to maximise energy efficiency and product quality in the spring making, mining, forging, agricultural and horticultural industries in particular.

Based on convective heating technology, gas fired rapid heating furnaces have transformed the entire metal reheating process from an inefficient, low productivity procedure to a highly efficient, fast and cost-effective operation. Fairbank Brearley individually design each system to the customer’s specification, using advanced technology and the depth of knowledge and experience built up over 40 years experience in the field.

Traditionally, furnaces have diverted a large proportion of heat input into wasteful heating of large chambers and refractory walling, with the consequent slow start up and cool down times as troublesome as scaling and decarburisation problems. The gas fired rapid heating furnace’s low thermal inertia allows heating of stock within minutes of start up, rather than hours. Additionally, sensitive response to changes in heat input contributes to a more efficient control of product temperature and to the resultant improved product quality.

From initial installation the system promotes continuous economies whether on automated, high volume production lines, or intermittent use in small workshops. In some instances, pay back in gas savings alone has been achieved within twelve months.

Compared to equivalent conventional furnaces, the reduced floor area requirement, simple maintenance and quick servicing, means that the gas fired rapid heating furnace system offers significant benefits.
