More so than ever before, companies are looking for reliable equipment solutions to maximize production and minimize downtime.
In particular, temporary air and nitrogen solutions play a valuable role in maintaining seamless operations during several phases in industrial projects.

Air compressors can be categorized as either oil-free or oil flooded. The type of compressor selected for the application is critical as the air quality between the different categories varies substantially.
Low emission diesel engines and electric-driven oil-free compressors are the types most commonly utilized in the industry.
For moisture-free air, desiccant air dryers can be supplied together with compressors to achieve different dew points. The typical dew point requirement is -40°F (-40°C). However, solutions for extra dry air with dew points of -94°F (-70°C) are also available.
Onsite nitrogen generation using membrane technology to supply nitrogen gas at different flow and pressures, with purities up to 99%, is becoming a preferred choice for most customers.
A typical nitrogen spread includes Class 0 feed air compressors and nitrogen membranes.
The onsite nitrogen membrane generation system provides nitrogen on demand and at various purities, flows and pressures. It also eliminates the boil-off losses during the transportation and gasification of liquid nitrogen, which can sometimes be substantial.
When considering the procurement of a specialized rental solution for a temporary need, it is important to look at the total solution, not just the equipment supply. It is advantageous to have contingency planning of temporary air and nitrogen requirements for the critical process and applications system and to work with a supplier that is well educated of the various applications and who has excellent project management and engineering capabilities. A supplier qualified in these attributes can add significant value during the contingency planning process.
The logistics of the operation can often be managed from project commencement, to completion and installation. Commissioning and operator services may also be useful where site labor is constrained. Energy management, such as re-fuelling services, also reduces the project management workload.
Final consideration should be given to the level of remote monitoring required. This is where a satellite-based system can alert the supplier of any potential problems. A rental company that provides this service, will remotely monitor fleet performance to improve machine up-time, security and safety.
The reliability and quality of equipment, the ability to provide the highest quality oil-free air, specialized knowledge and engineering capabilities make a compressed air and nitrogen rental company a preferred choice for industrial customers worldwide.
