As global manufacturing moves toward greater flexibility, energy efficiency, and faster project deployment, manufacturers are focusing not only on production capacity, but also on operational flexibility and cost efficiency. Traditional large industrial facilities are generally characterized by extensive infrastructure requirements, civil engineering, and lengthy development time. Today, however, there is a tendency to abandon those traditional approaches in favor of more agile methods represented by modular air separation unit (ASU) technology.

As a professional gas separation equipment manufacturer that offers comprehensive industrial gas separation services for over two decades, DINAK has been actively involved in developing modular cryogenic air separation solutions for industrial applications. DINAK has already delivered almost 300 projects and improved operational efficiency and reduced industrial gas supply costs through modern technologies. DINAK specializes in providing highly efficient Skid-Mounted Air Separation Unit designs based on advanced cryogenic technologies that enable rapid on-site industrial gas generation. In this blog, we explain why the modular approach to industrial gas plants has become popular nowadays, as well as the benefits that you can receive by using customizable gas systems from DINAK.

Understanding Modular ASU Technology

Defining the Modular Air Separation Unit

A Modular Air Separation Unit, also referred to as a Small-Scale ASU, is a compact cryogenic air separation system designed for on-site industrial gas production. In contrast to conventional plant construction, this kind of modular plant is extremely integrated, with the main modules being the air compressor, the pre-cooling module, the purifier, the turbo expander, and the distillation column. The process includes air compression, purification, cryogenic cooling, and low-temperature distillation to separate oxygen, nitrogen, and argon.

Evolution of Cryogenic Design

The transition from the conventional design to the modular design is a big step forward in terms of engineering approach. We at DINAK always concentrate on achieving the highest level of productivity within the smallest space occupied by our machines. Our Modular ASU systems are compact and easier to operate and maintain in comparison with bulky installations of earlier gas plants.

Fast Deployment with Skid-Mounted Designs

Benefits of Skid-Mounted Structures

The key feature of the DINAK modular ASU lies in its fully skid-mounted configuration. The advantage of such an arrangement is that the core process modules is assembled on a stable frame known as a “skid” within the manufacturing plant premises itself. Thus, the testing of the apparatus under pressure and vacuum conditions can be done in the factory itself.

Shortening the Installation Cycle

One of the biggest strengths that we offer to our customers is the rapid project deployment capability. Since the systems are modular, the number of tasks related to installation at the client’s facility is substantially reduced.

Significant Cost Reductions for Facilities

Lowering Civil Engineering Expenses

Air separation units that use conventional methods need extensive foundation construction and complicated structures to construct their plant. On the other hand, our Small scale ASU has a smaller requirement for foundation work because of its compact nature.

Minimizing Logistics and Assembly Costs

The transportation of the modular system will be much easier compared to that of the loose parts. Our modular systems can easily be transported; moreover, using the modular piping and quick-connect interfaces for our modules will make assembling the modules much easier, reducing the need for large construction crews on-site.

Flexibility Through Customized Gas Solutions

Tailoring Systems for Specific Needs

We recognize that each industrial process has its unique needs. DINAK designs customized gas systems according to the individual operating conditions and energy utilization needs of our customers.

Scalability and Future-Proofing

This modularity enables a degree of scalability that cannot be achieved by conventional plants. In case there is an increase in gas demand for the plant, additional modules may be added to the already existing configuration.

Ideal Solutions for Overseas Projects

Simplifying Logistics for Global Sites

DINAK has supplied modular ASU systems to customers in more than 30 countries, ranging from Russia, Southeast Asia, and even the Middle East. Modular units work great in these international settings since they are almost fully built and require little local assistance.

Reliable Generation in Remote Areas

The Modular ASU is crucial for any industrial unit situated far away from centers where the access to reliable industrial gas supply is limited, since using this equipment allows such industries to produce industrial gases on-site.

How DINAK Optimizes Your Supply

Advanced Engineering for Efficiency

Efficiency is one of the key principles we follow in our engineering philosophy. DINAK employs an advanced low-pressure technology, which ensures that the pressure requirement of our main air compressor can be brought down to as low as 0.43 MPa. Moreover, we do not require any additional external oxygen compressor for generating pressurized gas products.

Full Lifecycle Service Support

We don’t merely supply equipment; we have a full-service and guarantee program in place. One of the features of our service is Remote Monitoring and Diagnostics, enabling our engineers to give you 24-hour technical assistance, as well as warning signals before any failures occur. Moreover, we also conduct professional training of your technicians for optimal management of the Modular ASU.

Conclusion

The move towards modularity in the industrial gas industry is the move towards smarter and more sustainable manufacturing processes. A Modular ASU by DINAK is not simply a piece of industrial equipment; it's an intelligent choice towards a more flexible and sustainable manufacturing process in general.
