Expo is a world leader in the design and manufacture of purge & pressurization systems for electrical enclosures, analysers and other equipment.
As one of the most compact and flexible X purge systems on the market, the SmartPurge II is ideal for OEM systems and gas analyser applications.
It can be configured to operate in leakage compensation mode with a separate intrinsically safe solenoid valve, or in continuous flow mode with a manually operate needle valve. We can also supply a variant that can work with external fan air, where clean, dry compressed air is not available.
With a maximum flow rate of 540 NLPM, the SmartPurge II can protect enclosures up to 10m3, depending on purge time.

Not all electrical equipment is installed in a fixed location, some applications require mobility, such as service equipment or analysers. Purge and pressurization are still a great protection method and, provided instrument air is available, enables these mobile applications.
Expo Has built many mobile systems - take a look at these case studies for more details:
