Coil Heaters

----Coil Heaters.jpgDurex Industries manufactures coil heaters that feature continuous operating temperatures up to 1200°F (649°C). Rapid heating and cooling occur, due to the low mass construction. All heating elements are sealed from contamination and the stainless steel sheath provides maximum corrosion resistance. An optional internal thermocouple may be utilized for over temp control.
