JAD Shell & Coil Heat Exchangers

JAD heat exchangers JAD heat exchangers due to their design and performance are ideally suited to the most demanding applications. Large heat exchange area within compact dimensions and high performance comparing to standard solutions are widely appreciated on the market. Made entirely of stainless steel, they constitute a durable construction. Design flexibility make them suitable for most heat transfer systems. Due to their properties, JAD heat exchangers are mostly used in heating installations and substations, while JAD X in installations with increased requirements.

Why to choose JAD heat exchangers? SPACE SAVING Compact dimensions and vertical installation reduces space required for installation. X-shaped connections and corrugated tubes make the exchangers more resistant to fauling. HIGH EFFICIENCY WIDE APPLICATION Higher heat transfer coefficient - corrugated tubes promote flow turbulence and thus intensify heat exchange. Wide range of temperature and pressure, flow velocity and media. EASY SELECTION Manufactured in accordance with ASME, PED. With user-friendly CAIRO Selection Software.

JAD construction Coil ended on both sides with tube sheets placed in heads. Tubes side connections Dished head Heat exchange area consists of layers of helicoidal coaxial counter coiled tubes of diameter Ø 8 mm or 10 mm (0.31 in or 0.39 in). Connections to be welded WD external thread GZ Victaulic VC shell side connections Non-dismountable welded construction. High-alloy austenitic stainless steel. Vertical mountin
