WTG 634 heaters are horizontal indirect fired water bath heaters. WTG 634 gas heaters are designed to preheat the natural gas prior to the pressure reduction process in order to prevent cryohydrates formation because of the Joule-Thomson effect. The working principle: the heat is transfered from the firebox to the coil tube brundle through wich gas flows, by means of the wather bath.
