Z8 functionality in a sealed NEMA enclosure

The Zaxis Z8N is a Z8 multi-tester packaged in a larger sealed NEMA enclosure for industrial leak-testing installations. It provides the same functionality as the Zaxis Z8 or Z5 leak tester while placing the tester in an enclosure designed for use in large industrial areas.

The enclosure is not a one-size-fits-all cabinet. Multiple enclosure sizes are available, and the orientation of the fittings can be customized to suit the installation environment. That configuration flexibility lets the Z8N fit the physical needs of an application while retaining the tester’s configurable leak-test platform.

For production setups that require larger pneumatic hardware, the Z8N enclosure has large internal capacity for large valves. Valve options are available from valve sizes from low-flow to high-flow, and custom configurations are available for application-specific requirements.

The Z8N is tightly sealed to reduce dust and water accumulation. The NEMA box is generally rated at IP66 or IP67 and is rated NEMA 12, giving teams a clearly identified enclosure option when dust and water exposure are part of the installation environment.

Why Choose a Z8N NEMA Enclosure for Industrial Leak Testing?

The Z8N brings the Z8 multi-tester platform into a larger sealed enclosure for industrial areas. Its purpose is to pair configurable leak-test functionality with an enclosure that can be sized, fitted and configured for the surrounding installation rather than asking the installation to conform to a fixed cabinet. This makes enclosure size, fitting orientation and internal capacity part of the same configuration conversation as test pressure, test method, valve selection and communications. The platform can therefore be arranged around the application instead of a fixed product layout.

A Z8N configuration starts with the physical enclosure. Several sizes are available to fit the environment, and fitting orientation can be customized. Inside that enclosure, capacity for large valves and the available valve sizes from low-flow to high-flow valve options support configurations that need more pneumatic hardware than a smaller fixed enclosure can accommodate.

Benefits of the Z8N Industrial Air Leak Tester

The Z8N combines a configurable tester with a sealed NEMA enclosure. Its available pressure ranges, screen sizes, valve options, communications and power configuration give each installation a defined set of choices; the enclosure then adds multiple size options, customized fitting orientation and room for large valves.

✓Larger sealed NEMA enclosure with the functionality of the Zaxis Z8 or Z5 leak tester.
✓Tightly sealed enclosure that reduces dust and water accumulation.
✓Multiple NEMA enclosure sizes available for the installation environment.
✓Customizable fitting orientation to suit the surrounding equipment and access needs.
✓Large internal capacity for large valves.
✓valve sizes from low-flow to high-flow valve options.
✓5-inch or 8-inch color touchscreen options.
✓Custom configurations available for application-specific requirements.
✓RS232, I/O, Ethernet (TCP/IP) and Ethernet/IP communication options.

Configuring a Z8N for an Industrial Installation

The Z8N is configured around the requirements already established for the application: the enclosure size, fitting orientation, valve option, display size, test pressure, test type and communications. Those selections allow the NEMA-box platform to be matched to the environment and leak-test task. The configuration also has a material-compatibility check: use clean, dry, non-corrosive gases compatible with aluminum and 316 stainless steel.

Select the enclosure

Choose from the available NEMA enclosure sizes to fit the installation environment. The sealed enclosure is used where reducing dust and water accumulation is important.

Arrange the fittings

Specify the orientation of the enclosure fittings to suit the environment. This makes the connection layout part of the configuration rather than a fixed detail.

Set the tester configuration

Select the test type, available pressure range, display size and valve option required for the application. valve sizes from low-flow to high-flow valve options and either a 5-inch or 8-inch color touchscreen are available.

Connect the installation

Use the communication options that fit the application: RS232, I/O, Ethernet (TCP/IP) or Ethernet/IP. The Z8N uses 115/230 VAC, 50/60 Hz auto-sensing power at 60 Watts.

For media compatibility, use clean, dry, non-corrosive gases compatible with aluminum and 316 stainless steel. When a gas is not compatible, contact Zaxis to examine alternative solutions.

Leak Test Types

The Z8N can be configured for pressure decay, vacuum decay, occlusion, mass flow, burst, chamber and pressure-cracking testing. The selected test method is paired with the required configuration, and up to 100 stored programs provide a way to program and automate leak-testing specifications while minimizing user error.

Where the Z8N Fits

The Z8N is intended for installations where the enclosure itself needs to be part of the leak-test configuration. Its available choices address the application’s space, fitting layout, pneumatic-valve capacity and environmental exposure.

Large industrial areas

The Z8N packages Z8 or Z5 functionality in a larger sealed NEMA enclosure for use in large industrial areas.

Dust and water exposure

The tightly sealed enclosure reduces dust and water accumulation and is generally rated IP66 or IP67; it is rated NEMA 12.

Large-valve configurations

Large internal capacity allows for large valves, with valve sizes from low-flow to high-flow valve options available.

Technical Specifications

The Z8N is configured to the application. The values below cover the enclosure, measurement, pressure, display, valve, media, communication and power options for this NEMA-box platform. Select the configuration that fits the testing environment and the required test method. The 0–3 up to 1,000 PSIG positive-pressure choices and the vacuum to −14.5 PSIV option allow the pressure selection to be matched to the application, while the 7-inch and 4.5-inch display choices provide an operator-interface option.

Testing Performance

Zaxis air leak testers share the same test methods and resolution; they differ in enclosure, channel count and interface. The Z8N puts the Z8 feature set inside a sealed NEMA enclosure for large industrial areas, so compare it against the panel-mount models when the environment, not the test, is the deciding factor.

Industries We Serve

The Z8N suits plants where the tester has to live on the floor rather than in a control cabinet. The sealed enclosure keeps dust and washdown away from the same test electronics used across the Zaxis range, so the method can stay matched to the part while the enclosure matches the environment.
