The CEDAR series is designed to produce high purity industrial and medical grade liquid oxygen, nitrogen and argon. Plant capacities range from 54 to 61 metric tones per day of high purity product. Unique modular plant design with a single compressor cycle minimizes installation time and cost. A simple battery limits – power to the air compressor and power to the medium voltage distribution, instrument N2 (for start-up only), and LIN, LOX and LAR connections. A comprehensive scope of supply including interconnecting piping and electrical, installation drawings and a complete set of reference documentation that simplifies plant installation.

Ultra-low specific power consumption minimizes operating cost. Low capital cost through the highly efficient single compressor design. High purity nitrogen gas is available for future pipeline supply or liquefaction. Advanced PLC based control system with user friendly PC based HMI is designed for unattended and automatic operation, with provision for local or remote access via the internet. Single button start is available as an option.

The plant is configured for ease of maintenance and a minimum footprint. Designed for simplicity and ease of operation, the CEDAR uses the latest technology and high quality components. All plant modules – process air compressor, air chiller, air purification, turbo-expander skid and cold boxes are factory tested prior to shipment.

The TGN series plants produce high gaseous nitrogen by cryogenic distillation of atmospheric air. In addition, they also produce a small amount of liquid nitrogen to store for peaking or back-up purposes. The TGN series plants are efficient, reliable, and compact.

The TGN series plant utilizes a waste gas expansion cycle using a Turboexpander to produce gaseous and liquid nitrogen. The layout is configured to provide maximum efficiency and ease of maintenance. The plant consists of three modules, an Air Compressor Module (ACM) that provides process air, a Warm Equipment Module (WEM) that purifies compressed air and a Cold Box Module (CBM) that houses the distillation equipment. These modules are pre-wired and pre-piped for ease of installation.
