TEMPORARY FURNACES The heat treatment of large workpieces often has to be carried out on site. The transportation of large workpieces in stationary furnaces is a costly, time-absorbing and sometimes impossible operation. In such cases, a temporary furnace can be built from modular furnace elements - on the site or in a production bay. HeatMasters’ modular furnace system makes it possible to carry out on site heat treatment of large components, such as spherical tanks, gas tanks or columns. The size of the furnace can be specified in 1000 mm modules.
