Overview

The Noblegen Cryogenics LN240B liquid nitrogen generator is the reliable and efficient on-site cryogenic solution. With a small footprint, low power consumption, and low cooling water requirement, the LN240B is the perfect solution for you.

With cooling water, the system can operate in up to +52°c ambient temperatures which makes it suitable to operate in most parts of the world. Simply connect the power, cooling water (integrated air compressor), press start and the generator will automatically produce liquid nitrogen when needed

The Pressure ‘BOOST’ system increases liquid nitrogen production with no additional power or cooling water required. Coupled with the ‘No Loss’ pressure maintaining system, the LN240B is one of the most efficient and intelligent GM-based generators available.
