Welker designs and manufactures turnkey sampling systems, odorization systems, and gas conditioning solutions. Our turnkey systems bring specialized expertise, manufacturing quality, and single-source accountability to your operation.

Welker Made™

When It's Welker Made™, You're Getting Quality.

Welker Made™ is our promise. Every system that carries the name is engineered and manufactured with care by the people who designed its critical components — not assembled from parts sourced across multiple vendors.

Critical components designed and built in-house

Engineered for your application, site, and standards

Assembled and tested under one roof before it ships

Supported directly by the manufacturer for the life of the system

Manufacturer vs. Integrator

Why Not Get the Whole System From the Experts?

Integrators assemble systems from third-party components. Welker designs and manufactures the components that make the system work — and engineers the system around them.

Consideration Welker Made™ System Typical Integrator
Who Designs the Core Components? Welker designs and manufactures the critical components, including probes, samplers, cylinders, conditioners, and odorization hardware. Core components are typically sourced from multiple third-party manufacturers.
Application Expertise Sampling and odorization are our specialties, backed by decades of application-specific engineering and manufacturing experience. Sampling and odorization may be one of many disciplines within a broader engineering project.
System Accountability One manufacturer responsible for engineering, manufacturing, system integration, and support. Responsibility may be divided between the integrator and multiple component manufacturers.
Quality & Manufacturing Engineered, manufactured, assembled, and tested under Welker's ISO 9001:2015 certified quality management system. Component manufacturing and quality processes may vary between suppliers.
Service & Support Direct access to the manufacturer for technical support, replacement parts, and system expertise. Support and replacement parts may require coordination between multiple suppliers.
How It Works

From Concept to Commissioning

Tell us about your application, site conditions, and standards. Our engineers size the system with you.

2

Engineer

We design the complete package — enclosure, skid, or building — around Welker components.

3

Build & Test

Manufactured, assembled, and tested under one roof before it ships.

4

Commission & Support

Startup assistance, training, and factory support for the life of the system.

FAQ

Common Questions

Why buy a complete system instead of components?

A complete Welker system is engineered as one package, so every component is sized and matched to work together. You get one point of accountability instead of coordinating multiple vendors.

Our project uses an EPC or engineering firm. Can we still get a Welker system?

Yes. Ask your EPC or engineering firm to specify a Welker Made™ system. We work directly with your project team on drawings, specifications, and documentation.

What does Welker Made™ mean?

It means the system was engineered and manufactured by Welker, with critical components designed and built in-house and tested before it ships.

Can I still buy individual products?

Yes. Components are available on its own. Browse the full line on the Products page.

Who do I call for service?

Call Welker directly at 281.207.1887 or email sales@welker.com. The team that built your system supports it.
