The Munro series provides flexibility to match your system requirements.
The Munro series of high flow rate Nitrogen generators which is a range of
discrete, efficient and modular Nitrogen generators that produce dry nitrogen only
when you need it. The Nevis series uses Pressure Swing Adsorption (PSA)
technology for superior performance and reliability. The series includes a range
of models to cover most applications. When selecting a system, consideration
should be given to the required flow rate, purity and delivery pressure. Additionally
Apex will be happy to consult with you as to which specific model would suit you.
Each high purity nitrogen generator in the series can be run from an external source of
compressed air or can be built with an integral compressor. Using an external air source
air will provide almost silent operation. An integral compressor allows the system to run as a
complete stand-alone solution.
Maintenance of your Nevis Series High Purity Nitrogen Generator is simple with all regular maintenance parts being easily accessible, for peace of mind we offer a service package. Currently, this is only available to UK customers but if you are elsewhere, we have a wide network of service companies which we trust.
An on-site nitrogen generator provides several benefits over bottled gas:
Save money: You never have to pay for bottled nitrogen again.
Save space: A nitrogen generator requires less space than storing gas cylinders.
Improve workplace safety: Employees don’t have to move heavy gas cylinders, nor do you have to store high-pressure tanks.
Reduce delays: You don’t have to wait for deliveries of bottled gas.

All Apex units are supplied with our standard 1 year warranty. Accompanied with our on-going care and servicing facilities Apex provides the highest quality peace of mind.
Designed for the Mass Spectrometry market, the Munro Nitrogen Generator range is an extension of the Nevis range. The system is economical to run, producing nitrogen only when needed.
The Apex Munro is a discrete, efficient, modular system that produces high purity nitrogen only when you need it. The Munro uses PSA technology for superior performance and reliability.
A range of models, including options for built-in compressors, is available to cover a wide range of applications. The larger units are fitted with castors to allow them to be manoeuvred easily into position. Most models in the series will fit under a workbench.

How it works:
Air from an external source enters the generator via a 0.01-micron filter  that removes contaminants and bulk moisture via an integrated auto drain. When the control system assesses that more nitrogen is required, the solenoid valve  is opened and pressure is allowed to build in the column  containing Carbon Molecular Sieve (CMS) and a residue moisture catcher .This sieve adsorbs the oxygen and leaves the dry nitrogen free to flow through the non-return valve into the direction of the variable reservoir capacity (VRC)  Following on from this the Nitrogen is allowed to flow to the application via another 0.01-micron filter  and pressure and flow regulators .The trapped oxygen is meanwhile filtered out through the exhaust valves
