Skid Mounted Unit

“Compact” means the solution is engineered to reduce complexity on site. Instead of building a filling station from multiple separate packages, this approach streamlines deployment with a practical, integrated layout. That is valuable for remote sites, fast projects, and facilities that want a dependable cylinder-filling capability without extensive engineering work or long commissioning timelines.

For installations where mobility matters, compact skid configurations support practical relocation and easier movement within a facility. This is useful when operations evolve, when construction phases require temporary positioning, or when the oxygen supply needs to be moved to match production changes.

The station generates oxygen using PSA (Pressure Swing Adsorption) technology and includes high pressure compression for filling oxygen cylinders. In PSA oxygen generation, compressed air is separated through molecular sieve beds that preferentially retain nitrogen under pressure, allowing oxygen enriched gas to pass through as product. After oxygen is produced, it is compressed to the required high pressure so cylinders can be filled consistently and efficiently.

An important operational advantage is automated control behavior during filling. The station is designed so filling can stop automatically when charging is complete, helping reduce operator workload and supporting repeatable daily filling routines.

Capacity planning becomes straightforward because the compact station is specified with both oxygen production and cylinder filling throughput. Oxygen production ranges from 3.4 to 34.9 m³/h, while the filling capacity range of 13.6 to 139 cylinders per day is presented in a way that helps procurement and operations teams align equipment selection with real cylinder consumption. The cylinder/day figure is defined using a standard cylinder volume reference, making it easier to estimate results for typical cylinder fleets.

Purity choices of 93% and 95% allow you to align the station with your process requirements and filling strategy. End pressure options of 152 to 207 bar support high pressure cylinder storage needs commonly used in industrial distribution and on site inventory.

Oxywise supports multiple deployment approaches for oxygen filling stations so customers can match the solution to site conditions. A stand alone setup is a practical choice for indoor installations where space is available and service access is a priority. A skid mounted solution supports faster deployment and easier movement, typically with a compact, pre assembled layout that minimizes installation effort. A containerised version is ideal when the station must operate in harsh environments or remote locations, with the ability to specify the unit for challenging climate and exposure conditions.

This flexibility makes it easier to standardize oxygen filling capability across multiple sites—using a common technology foundation while selecting the physical format that best fits each location.

The compact station is designed to be robust and practical for real operating conditions. Standard features include stainless steel oxygen piping for durability, automatic behavior that stops filling when charging is complete, and an integrated oxygen analyzer with alarm function so operators have continuous visibility of oxygen quality during filling operations. Connection interfaces can be aligned to customer requirements, supporting integration into existing cylinder handling workflows.

Many sites want added protection and visibility in high pressure oxygen service. Optional features support this with remote alarm and control capabilities (including SMS), audio/visual alarms, sequential start/stop for simplified operation, and filling ramp options suitable for different cylinder sizes. For quality management and equipment protection, additional sensing such as product gas dew point measurement and temperature monitoring can be specified, alongside options that help protect the system from oil contamination—an important consideration in oxygen systems.

For compact skid deployments, planning the installation environment is essential for long-term reliability. A covered shelter or indoor installation is recommended for harsh or adverse conditions such as extreme temperatures, high humidity, saliferous air, or dusty/sandy environments. When planned properly, the compact skid approach can support semi permanent operation while still allowing relocation when needed.

Oxygen systems require disciplined safety practices because oxygen enrichment increases combustion risk. Safe operation depends on correct equipment selection, compatible materials, good housekeeping, and strict contamination control—especially in high pressure cylinder filling. A well-designed station supports safer operation through integrated monitoring, alarms, and protective options that help operators maintain control over the process.
