Shell and tube heat exchangers are the work horse of the industry since ages and still going strong even today. Efforts have been made in the past and also being made recent times for augmentation in the heat transfer and increase the efficiency of the heat exchanger. JONAM offers shell and tube heat exchanger with smooth and augmentated tubes. JONAM offers all type of TEMA and ASME configurations for all types of applications in Stainless steel and exotic material of construction. JONAM has an entire range of standard heat exchangers in single pass and multipass design which helps in quick selection of the heat exchanger to give an optimal and economical solution. Jonam can perform the thermal and mechanical designs for heat exchangers applications such as Condensers, Chiller, Cooler, Re –boilers (Thermo-siphon and Forced circulation) and Pre-heaters. The heat exchangers are designed for both the thermal and mechanical consideration an dintegration between these two aspects the design, be it tube sheet layout or baffle spacing and selection , Jonam has the expertise to apply the knowledge to design the heat exchanger optimally and i n entirety. The heat exchanger design does not end at providing sufficient heat transfer area for the given duty but to consider the design configurati on i n totality in the aspects of Impingement plates, Bellow requirements, Gasket selection and Arrangement and also the suitability of the tube to tube sheet joint for the application. The heat exchanger are designed as per GEP, TEMA, ASME, BS5500 etc and as per PED / CE mark. Pre-Engineered Heat Exchanger : Jonam has engineered heat exchangers to meet the needs of the customer With hi gh level of standardization Jonam has ready in stock semi finished components of heat exchanger such as Tubes, Plates and Flange. A comprehensive inventory of pre-engineered and stocked components ensures timely product delivery. The heat exchanger can be assembled i n the quickest possible time to meet the customer requirement. The heat exchanger are standardized to pass all the international standards and de-signs. The Standard model range includes the BEM fixed tube sheet and BEW Removable tube bundle and the BEU tube heat exchanger. Jonam offers standard range of heat exchangers from 1 m2 to 120 m2 in single and multi-pass confi gurati on in SS304 L and 316 L material of construction.

Jonam applies Corrugated tubes in its shell and tube heat exchangers. The corrugated profile on the inner and outer side of the tubes creates extra turbul ence. It disrupts the boundary layer near the tube wall where most of the resistance to the heat transfer takes place. The boundary layer near the tube wall helps the fouling to build up due to zero velocity at the tube walls. The extra turbulence created due to corrugation reduces the formation of fouling layers. Jonam has heat exchangers for Industrial applications based on TEMA and ASME configurations. The heat exchangers find successful applicati on in heat recovery , condenser and re -boilers. The major advantage of the Augmented tube heat exchangers are   Lower and reduced fouling Increased heat transfer due to increased turbul ence Lower heat transfer area is obtained for a given heat transfer duty. Reduction in the size / length of the heat exchanger. Lower floor space / foot print .
