AES Floating Head Heat Exchanger For Fine Electronic Chemicals
TEMA AES type floating head shell-and-tube exchanger with removable straight tube bundle. The floating head (S-type) allows free thermal expansion and eliminates differential thermal stress. Front head is A-type (flat cover), shell is E-type (single pass). The entire bundle can be extracted for mechanical cleaning and maintenance, suitable for high temperature difference and severe fouling services.
