Spiral Heat Exchanger
Conceptual Engineering & Design
In the conceptual engineering phase, we evaluate and refine process feasibility, operational efficiency, and financial viability. Our team develops optimized process schemes, process flow diagrams, and material and energy balances to guide decision-making. Whether scaling up from laboratory or pilot plant to commercial operations or modifying existing systems, we focus on enhancing throughput, improving yield, reducing emissions and adapting to changing feed conditions or operational modes.Basic Engineering
Basic engineering forms the foundation of every successful project. During this phase, we translate initial ideas into defined design parameters. We establish key project specifications, select appropriate technologies, and create initial design documents, setting the stage for detailed engineering. Our team ensures thorough feasibility studies and initial calculations are conducted, with all documentation aligned to industry standards to keep stakeholders aligned and the project on track.Front-End Engineering Design (FEED)
Our FEED services provide a comprehensive framework for project development. We combine engineering design expertise with project management skills to deliver high-quality results. From ensuring compliance with global standards to adapting to regional requirements, our team is equipped to handle multi-project, multi-geography demands. We support diverse industries, including chemicals, oil and gas, mining ensuring efficient and effective project delivery across India, the Middle East, Asia Pacific, the USA, and Europe.Technical Specifications

Product Features and Benefits
Self Cleaning
At fluid velocities that would normally be in laminar flow in other types of heat-transfer equipment, the flow in our Spiral Heat Exchanger is in fully developed turbulent flow. The continuously curving flow channel produces an intense scrubbing effect that prevents fouling deposits from forming.
No Leakage Risk
The single flow channel of the spiral heat exchanger eliminates leakage and bypassing streams common in shell-and-tube equipment (such as shell-to-baffle or tube-to-baffle leakage). The unit's single flow passage also eliminates flow plugging caused by mal-distribution and entrance/exit problems, which allows for easy handling of viscous materials.
No Dead Zones
Since there are no sharp turns or corners in the flow channel, eddying and stagnant areas are reduced or eliminated. This has the added benefit of reducing potential problems commonly caused by erosion. The spiral's thicker gauge material minimizes possible erosion and corrosion effects.
Higher Heat Transfer Rates
The flow in Spiral Heat Exchanger is practically 100% counter-current, which allows a high degree of heat recovery. The studs and the curvature of the single channel help to promote turbulence and thus heat transfer, which gives our Spiral Heat Exchanger up to twice the heat transfer coefficient compared to the S&T.
Smaller Footprint
The high heat transfer rate in combination with the spiraling channel makes our Spiral Heat Exchanger very compact in terms of m2/m3 and offers a small installed footprint. In addition, the service footprint is significantly smaller than for an S&T, which requires space for removing the bonnets, rodding the tubes or even extracting the tubes.
High Vacuum Applications to Highly Viscous Fluids
The single flow channel & reduced fouling results in achieving very low pressure drops in vacuum operations. Efficient handling of highly viscous fluids is also possible with compact Heat Exchanger size, minimum fouling & maintenance.
Suitable MOC for Every Critical Application
Spiral Heat Exchanger can be manufactured in materials such as Stainless Steel to be used in pharmaceutical industry or in exotic materials such as Hastelloy, Titanium, etc. to handle corrosive fluids used in Steel, Chemical, Fertilizer & Petrochemical industry.

Frequently Asked Questions (FAQ)
Although Spiral Heat Exchangers are suitable for all basic heat exchange applications, the most preferred or suitable application is with fluids having higher viscosity or solid suspension where higher velocity can be achieved even with lower flow rates to increase the heat transfer coefficient and simultaneously reduce the Heat Transfer Area ultimately reducing the equipment cost.
The size of the heat exchanger depends on factors such as the flow rates, temperature requirements, and specific heat transfer needs. Our team can assist you in selecting the appropriate size based on your application.
Yes, spiral heat exchangers are designed to accommodate both pressure and vacuum conditions, making them versatile for various processes.
Routine inspections and cleaning are recommended to ensure optimal performance. The frequency of maintenance depends on the application and fluid characteristics.
Spiral Heat Exchangers can be manufactured in almost all metal materials which are available in plates/ sheets since we are rolling the sheets one over the other to form flow channels. The restriction is on plate thickness and not on the material.
The Spiral Heat Exchanger has a size limitation in manufacturing which is dependant on the roller machine capacity. As far as concerned, we can manufacture up to 120m2 Heat Exchanger in current setup. For going above the this requires more space availability along with funds.
