Oxygen/Nitrogen Air Separation Plants
7-20 metric tons/day Liquids

The Spruce ASU’s meet the demanding needs of remote island locations and emerging markets. With models ranging from 7 – 20 tons per day, the Spruce ASU plants were specifically designed to meet the logistical,¬†technical, infra-structural and environmental challenges of remote locations such as tropical islands or¬†emerging countries. They provide an elegant, cost-effective and robust solution to the challenges of island¬†industry, or those locations where infrastructure and technical resources may be limited. These flagship¬†packaged plants represent a new era for modular ASU’s, combining our Cosmodyne plant‚Äôs traditional robust¬†mobility with high efficiency and state-of-the-art control and PLC logic.


A vast amount of time and energy has gone into transforming our modular concept plants into a product that meets the modern needs of these remote locations. Mobility, reliability, safety and durability have always¬†been important, but the cost of energy and resources is now a primary concern for all of our customers, as is¬†the need for fast and inexpensive technical support. We have utilized innovative thinking and the¬†phenomenal technology now available in the world of instrumentation and PLC control, to create a solution¬†that represents a whole new platform of small ASU’s. We‚Äôre extremely proud of the Spruce range.


Cosmodyne Packaged Plants is pleased to offer our Spruce Air Separation Plants that produces liquid nitrogen and oxygen by cryogenic distillation of atmospheric air. The Spruce plants are pre-wired and pre-piped for a compact, modular design. This allows for simple initial field erection or relocation.
