AA & STA Series construction
BAFFLES CNC manufactured baffles to provide maximum turbulence and heat transfer with a minimum fluid pressure drop. FINISH
THREAD C N C p r e c i s i o n threading to provide accurate leakproof connections.
TUBE JOINT Roller expanded tube joint to integral forged hub.
CAST BONNET Provides f luid into tubes with minimum restriction. One, two, or four pass inter- changeability.
FLOW CAVITY Generously sized to al- low for minimum pres- sure drop and more uniform flow.
Gray semi - gloss enamel. Can be used as a base for additional coats.
MOUNTING BRACKET
Heavy gauge steel mount ing brackets are ad j us t ab l e i n orientat ions to 360 degrees.
BUNDLE ASSEMBLY CNC precision manufac- tured parts to guarantee a close f i t between the baffles, tubes, and shell. Clearances are minimized to provide for maximum heat transfer.
FORGED HUB Premium quality forg- ing with full opening designed for minimum pressure drop.
FULL FACE GASKET Ful l - face composi te gasket.
DRAIN PORT Drain ports allow for easy draining of tube side. Opt ional zinc anode can be inserted in place of plug.
