Used Nitrogen Generators, Oxygen Generators and Accessories

Used Equipment

Holtec Gas Systems (Holtec) offers used equipment for prices substantially below new equipment prices. We invite you to contact us should you have a Gas Generator or related equipment you would like to sell or trade, or if you are interested in buying used equipment.

Holtec does currently have one NEVER USED membrane system and several used PSA and Membrane type Nitrogen Generators for sale. One Membrane System shown below, supplied with feed air compressor, was built for hazardous area classification and used by a major Norwegian oil company. A description of some of the systems we have for sale is given below:

Pressure Swing Adsorption type Nitrogen Generators:

Holtec does currently have a used PSA system with air and nitrogen receivers, 10,000 gallon storage tank, air compressor, desiccant dryer and deoxo system in stock. The system was originally built by MG Industries and of CarboTech design. It can be sold "AS IS" or refurbished to "AS NEW" condition. The capacity for the PSA system was 16,000 SCFH = 428 Nm³/h - 98% N^₂. However, this capacity can be more than doubled by replacing the Carbon Molecular Sieve (CMS). Please contact Holtec for pricing and detailed performance information. The system can be seen on following pictures:

Membrane type Nitrogen Generator:

Holtec does currently have a new Membrane Type nitrogen generator with nitrogen receiver in stock as shown in the picture to the right. This generator is typically used for tire inflation, but can be used for other applications as well. The system is available for a very favorable price. We have parts in stock to make several similar nitrogen generators as well. These systems are blue with a white panel mounted on the front of the tank.
