Welmech engineering has developed eco-friendly, pollution free auto controlled gas / oil fired furnaces suitable for use in heat treatment plants. These furnaces are equipped with ecoflam italian burners and are 30 to 40 % cost effective than the other conventional furnaces.The furnaces are constructed with ceramic modular lining. These gas/oil fired furnaces are available with salient features like programmable controlling devices and digital temperature recording devices. These furnaces can be applied in areas such as annealing, tempering, hardening and stress relieving process.
