In the production chain of the pharmaceutical industry, the steam system is called the vital "lifeline", from the synthesis reaction to the final sterilization and packaging of drugs, every link is inseparable from its support. Spirax Sarco, as a global leader in steam and thermal solutions, has built a set of professional solutions covering the whole life cycle of "Research - Design - Implementation - Operation and Maintenance" for the pharmaceutical industry based on a hundred years of professional accumulation, which can meet the stringent regulatory requirements while realizing the double enhancement of production efficiency and energy efficiency.
Industry Pain Points and System Value: The Multi-Dimensional Challenges of Steam Applications
In the energy consumption map of pharmaceutical companies, the steam system occupies a prominent position, and its energy consumption can often be up to 30% - 50% of the total energy consumption of the whole plant. behind this huge energy consumption, there are a number of key challenges: on the one hand, the cGMP specifications put forward very high requirements for the quality of the steam, such as the purity of the clean steam must meet the USP Class VI standard, to Eliminate any possible product contamination; on the other hand, the specificity of pharmaceutical processes, such as sterilization in vaccine production, temperature control of bioreactors, etc., all have nearly demanding needs for steam stability and precision. Any fluctuations in the steam system can not only lead to production interruptions and increased operating costs, but can also affect the quality of the drug product, posing serious compliance risks.
Spirax Sarco has found through in-depth industry research that there are three major pain points in traditional steam systems: unstable steam quality, which directly affects the uniformity of pharmaceutical production; inefficient condensate recovery, which results in a double waste of energy and water resources; and a lack of foresight in system maintenance, which leads to frequent unexpected failures. The root cause of these problems lies in the disconnect between system design and process requirements, as well as the lack of professional management of the entire life cycle.
Full chain solution: professional closure of the loop from blueprint to landing
Scientific research: data-driven systematic diagnosis
Spirax Sarco's steam system research service is the industry's "Precision Physical Examination". A team of professional engineers uses advanced testing equipment, such as steam quality testers and trap testers, to quantitatively analyze the system in all aspects. In the case of a biopharmaceutical company in Hubei, engineers pinpointed design flaws in the condensate recovery system through on-site inspections and found that the system wasted as much as 151 TP3T of energy due to flash steam losses. based on this data, they customized a retrofit plan that included a flash steam recovery unit and high-efficiency traps, which ultimately helped the company achieve an annual energy savings of 8,664,600 MJ. The result was an annual energy saving of 86,646,600 MJ.
This research is not only limited to the equipment itself, but also covers multiple dimensions such as energy management processes and operator habits. By creating detailed system accounts and energy consumption models, Spirax Sarco is able to identify improvement opportunities for its customers along the entire chain, from equipment optimization to management enhancement.
Compliance design: the fusion of international standards and customization
As a member of ASME - BPE and ISPE, Spirax Sarco's design solutions strictly follow the highest international standards. In a project for an insulin manufacturer, its customized clean steam system was strictly controlled from material selection to welding process. The system is made of 316L stainless steel and is electropolished with surface roughness Ra≤0.8μm, which fully meets the cGMP requirements for clean surfaces. Meanwhile, the design team also innovatively integrated the total depressurization metering station, clean steam generator and condensate recovery unit into a compact skid-mounted unit, which not only saves the installation space of the 30%, but also improves the maintainability of the system through the modular design.
During the design process, Spirax Sarco always adheres to the dual orientation of "compliance" and "functionality". Its solutions not only meet the requirements of cGMP, FDA and other regulations, but are also optimized according to the customer's specific process requirements, such as the sterilization temperature profile and the temperature control accuracy of the reactor. For example, the TCU temperature control unit designed for a biopharmaceutical plant has improved the temperature control accuracy to ±0.5℃, effectively solved the problem of large temperature fluctuations in traditional jacketed reactors, and significantly improved the batch stability of the product.
Full life-cycle services: from "one-off projects" to "continuous optimization"
Spirax Sarco has overturned the traditional "project delivery is the end" model and launched a service system that covers the entire life cycle of the steam system. Its annual maintenance service takes preventive maintenance as the core, and realizes the standardization and visualization of maintenance work through the establishment of detailed equipment accounts and maintenance plans. In the service of a foreign-funded pharmaceutical company in Shanghai, a team of engineers conducts quarterly system inspections, updates steam system PID charts annually, and provides customers with 24-hour emergency response services. This forward-looking maintenance model has reduced the customer's system downtime by 40% and extended equipment life by 20%.
In addition to hardware maintenance, Spirax Sarco also focuses on the improvement of "soft capabilities". Its steam system training courses have trained more than 8,000 people, with course contents ranging from basic steam principles to advanced system optimization, covering different levels of needs. This "teach a man to fish" approach helps customers develop a professional internal technical team and realize the continuous improvement of maintenance capability.

Spirax Sarco has the most complete steam system product matrix in the industry, providing the pharmaceutical industry with a full chain of products from steam generation to delivery, from quality control to condensate recovery. In the steam generation segment, its pure steam generator adopts multi-effect distillation technology, with steam production ranging from 50kg/h to 10,000kg/h to meet the needs of enterprises of different sizes; in the delivery segment, the pilot-type diaphragm pressure reducing valve can control pressure fluctuations within ±1% to ensure the stability of the process parameters; in the field of condensate recovery, the trap pump combines the functions of trap and pumping, and can realize condensate recovery without the need for external power supply. In the area of condensate recovery, the trap pump combines the functions of trapping and pumping to realize efficient condensate recovery without the need for external power supply, with remarkable energy-saving effects.
For the special requirements of clean systems, Spirax Sarco has set up an independent clean product factory, where its clean valves, fittings and other products are manufactured and packaged in a clean environment. For example, Steri - Trol pneumatic control valves with all stainless steel construction and no dead space design meet sanitary requirements and can be widely used in aseptic processes.
Rigorous Validation: Compliance Assurance from Documentation to Practice
In the pharmaceutical industry, compliance is a red line that cannot be crossed. Spirax Sarco has constructed a complete validation system, from design validation (DQ) to performance validation (PQ), and each step is supported by strict processes and documents. The documentation package it provides covers more than 20 items such as technical parameters, material reports, welding test reports, etc. Among them, the FDA and USP Class VI material reports provide a strong proof of the safety of the product contact surfaces.
In a project for a tablet manufacturer, Spirax Sarco's validation team ensured that the clean steam system complied with regulatory requirements from design to installation through rigorous FAT (Factory Acceptance Test) and SAT (Site Acceptance Test) processes. This "controlled process" validation concept not only helped the customer successfully pass the FDA and EMA audits, but also laid the foundation for the system's long-term stable operation.
Sustainable Development Practices: Synergizing Energy Efficiency and Environmental Protection
In the context of global energy saving and emission reduction, Spirax Sarco deeply integrates the concept of sustainable development into pharmaceutical steam system solutions. Through highly efficient heat exchange technology and condensate recovery system, its solutions can help enterprises realize energy savings of 15% - 30%. In the renovation project of a traditional Chinese medicine company, through the installation of a flash steam recovery unit and optimization of the steam piping network, the annual energy consumption was reduced by 10,800,000MJ, which is equivalent to a reduction of about 1,200 tons of carbon dioxide emissions.
Meanwhile, Spirax Sarco's solutions are also dedicated to the recycling of water resources. In a biopharmaceutical plant, the condensate recovery system designed by Spirotech has increased the condensate recovery rate to more than 90%, which not only saves a large amount of industrial water, but also reduces the load of sewage treatment. This double benefit of "energy saving + environmental protection" is an important reason for more and more pharmaceutical companies to choose Spirax Sarco.
