Natural Gas Preheaters
Pressure requirements were stringent – 2000 psi that required precise digital controls capable of maintaining steady increased temperatures (70 degree increments) and a fail safe backup. This was required in 4 separate facilities.
Solution
Wattco offered our skid mounted triple decker circulation heaters with 14 inch 900# stainless steel 316 flanges with pressure ratings of up to 2000 psi. The skid allowed for future modular changes along with NEMA 7 explosion proof controls mounted to facilitate easy access and temperature changes.
Inlet and outlets contained 6 inch 900# ANSI flanges that allowed easy hookup with existing piping and thermocouples at each exit port to monitor temperature increases. An SCR was used instead of contactors. Considering the area was classified as Class 1 Div 1, a NEMA 7 explosion proof terminal box was integrated for safety purposes. Wattco also offered a team of installers to help calibrate the temperature controllers as well as the installation of the units.
