One of the most characteristic features of the JAD family is the closely packed, circular layers of helically, corrugated tubes that constitute the tube bundle. Each layer is positioned in the opposite direction to the surrounding layer, resulting in an overall criss-cross pattern. The effect is a high heat transfer surface area within a compact space. The tube orientation fosters turbulent flow and creates more uniform heating of the fluids, thus increasing the overall heat transfer coefficient. Additionally, the inherent spring-like characteristics of the coiled tube bundle enable these heat exchangers to withstand high temperature differentials between the two mediums, variations in steam pressures, and possible steam hammers and shocks in the system.
The JAD angular connections accommodate smooth, gradual flow entrances and exits from the unit, reducing any sharp corners that can result in flow separation and where dirt buildup can occur. The vertical configuration has the intrinsic advantage of being used as a condenser or evaporator for supporting changes of fluid phases within the unit (e.g. steam to liquid). The small footprint results in less installation space requirements and low installation costs. It is ideal for applications with space constraints. The strength and durability of JAD heat exchangers are due to their complete welded, stainless steel 304L (316L-option) material of construction. This allows for high pressure and temperature ratings on standard products, and ensures that the products are suited for the most demanding of applications. After fabrication, the heat exchangers are additionally passivated and electropolished to enhance the corrosion resistance of the material.
Shell & Coil Models are available in: Smooth or corrugated (K models) tubes.
Steam
- Flooded Heat Exchanger
For steam applications, contrary to conventional designs, the unique JAD helically corrugated tube bundles and its vertical structure enable the heat exchanger to not only condense the steam, but also to sub-cool the condensate to within degrees of the incoming cold water, recovering the maximum amount of excess heat available. The bottom of the heat exchanger can be flooded to various degrees with condensate, enabling the operator to have smoother and better control of the performance of the overall system.
- Clean Steam Production
The vertical JAD design is often used in the generation of clean steam. Considered a refined ‘thermosiphon reboiler’, the partially flooded exchanger has the ability to superheat the steam, facilitating better control of the steam output, and allowing the transport of dry steam to other parts of the system. Additionally, its compactness is more desirable than standard submerged kettletype reboilers, which has larger footprint requirements.
Typical Applications
• district energy heating
• hydronic heating
• steam-water systems (flooding heat exchangers)
• chilled water systems
• ground water systems
• refrigeration systems (ammonia absorption, freon)
• clean steam generation
• vapour condensers
JAD Typical Construction
• Stainless steel 304L (316L-option) welded material of construction
• helically coiled tube bundles (corrugated or smooth)
• cascading connections
• vertical installation
Advantages
• large heat transfer surface area within a compact space results in a highly efficient and effective system
• complete Stainless steel 304L (316L-option) welded construction ensures strength and durability of product
• in reboiler applications design allows superheating of the steam
• as a vapour condenser it sub-cools the condensate
• coiled tube bundle and cascading connection angles prevent debris build-up, creating a selfcleansing effect
• compact vertical design requires small installation footprint – ideal for applications with space constraints
