Closed-welded reactors with main opening

The standard design glass-lined steel reactor for over 40 years, the SA series soldiers on into the 21st Century. The signature feature of the SA reactor is the large top head main cover. This “J” bolted opening was originally designed to accommodate installation and removal of the wide Retreat Curve Impeller (RCI). The RCI was the glass-lined steel industry’s standard from the 1920’s until the mid 1980s, when the introduction of the GlasLock^® separable blade impeller made obsolete the RCI, and the need for a large top-head opening.

Jacketed reactors are available with either a conventional jacket (SA) or with a HemiCoil® split pipe-coil jacket (CSA).

Advantages of the SA:

• Rugged heavyweight design
• Superior 3009 one formulation glass resists a wide range of chemical attack
• Jacket inspection/cleanout port eliminates dismantling of jacket piping, allows fast inspection and cleaning of reactor jacket
• Narrow annulus jacket spacing provides quicker heat-up and cool-down
• Standard 3000-lb. ANSI forged-steel jacket couplings are stronger, with greater corrosion allowances than other manufacturers
• Large main opening easily accepts wide one-piece glass-lined, alloy or fluoropolymer coated agitators (available through De Dietrich)

Upgrades available

De Dietrich’s high efficiency glass-lined steel GlasLock^® agitator easily retrofits all SA reactors. (Request Bulletin 118 for details on the GlasLock^® agitator.) Upgrades of drives, mechanical seals, baffles and other accessories will equip your SA reactor for years to come.

SA sizes range from 300 to 25,000 gallons. Popular sizes 300 through 4000 gallons (new and reglassed) are stocked at De Dietrich’s Corpus Christi, Texas manufacturing facility for quick delivery.

Spraying the Glass

Here we see a skilled technician applying our high performance 3009 glass formulation to a welded-up SA reactor. The glass lining is sprayed on the prepared steel, and then moved into the furnace to “fuse” the glass and steel together, via mechanical and chemical adherence. The 3009 glass formulation offers superior corrosion resistance over a broad range of chemical applications. (For more information request Bulletin “3009 Glass”.)
