Nitrogen Liquefiers provide sub-cooled liquid nitrogen from gaseous nitrogen feed gas for the many applications that use liquid nitrogen. Our Nitrogen Liquefiers are designed to provide you with liquid nitrogen from any clean and dry gaseous nitrogen source. Typically from the overhead nitrogen stream from an air separation plant (ASU) that would otherwise be vented.

Our modular Nitrogen Liquefaction Plants can be configured to specific needs, such as liquefying an oxygen gas stream or simultaneous liquefaction of oxygen and nitrogen gas streams. Flow rate, pressure, and purity level are all completely adjustable. These are equipped with single or dual Nikkiso Cosmodyne turboexpanders (> 500 Nm³/hr).

Ideal for emerging markets and remote locations, the ELM plants’ efficiency makes it equally suitable for more long-term production applications. The ELM Liquefiers allow conversion of a gas supply from an existing plant to liquid for storage. The gas can be supplied from a pipeline or vent gas off a PSA or Air Separation plant. The liquefier can also be used to recover flash gas in storage tanks. This innovative plant is built to meet the highest industrial gas safety and quality standards to ensure flawless and reliable performance under the most severe operating conditions.

The ELM plant is designed to minimize shipping and allow for rapid installation by providing the plant in distinct pre-piped, pre-wired modules. The plant system is self-contained and can be completely installed outdoors.
