Stainless Steel DOUBLE-TUBE

Double-Tube & Triple-Tube Economy Pays For Itself.
When you install a Triple-Tube Heat Exchanger, your first investment is just about your last. The stainless steel and Teflon gasketing are practically impervious to chemical reaction and for all suitable purposes has a "life time durability". Maintenance costs, therefore, are practically nill.

Double-Tube Construction allows for Product-to-Product Regeneration. The raw cool product flows in the inner tube counter-current to the heated product which comes from the heating section and heats this product. Savings of over 90% of the total heating or cooling load are realized.

The Unique Feldmeier Construction of bolted stainless steel flange joints and Teflon gasketing like the Triple-Tube, allows for tubes to be inspected separately. This construction also maintains product integrity, making co-mingling impossible. Tubes are mounted for complete drainage.

Clean-In Place is also a unique feature of the Feldmeier Double-Tube Heat Exchanger. Cleaning solution velocities of 5 ft. per second and up are readily attained in the inside tube and also the annular space.

Dimpled Tubes are a unique feature of Double Tubes and Triple Tubes. Outside-in dimpling insures concentric tube alignment and uniform flow space by eliminating tube sag. Dimpling produces C.I.P. cleanable smooth curved surface protrusions into product steam and permits use of 20 ft., 30 ft. or 40 ft. long tube systems.
