Four Key Credentials. One Commitment to Manufacturing Excellence.

When selecting a manufacturing partner for modular MEP systems, certifications matter. They demonstrate a commitment to established industry standards, rigorous quality-control processes, and technical manufacturing capabilities.

At Envirosep, our extensive portfolio of certifications and authorizations reinforces our ability to deliver reliable, factory-manufactured solutions for data centers, pharmaceutical facilities, healthcare systems, commercial and industrial applications.

From complex pressure vessels to fully integrated Modular Central Utility Plants, our credentials reflect the quality and expertise behind every project.

Certification and What It Means to our Customers

UL Listings - Independently evaluated product and system designs supporting electrical safety, compliance, and reliable integration.

ASME U Stamp - Certified manufacturing of pressure vessels under ASME Section VIII, Division 1, supporting dependable, code-compliant equipment.

ASME U2 Stamp - Advanced pressure vessel manufacturing under ASME Section VIII, Division 2, supporting specialized engineering and demanding operating conditions.

SBA HUBZone Certification -Federally recognized small-business designation supporting government contracting opportunities and American manufacturing communities.

UL Listings: Safety and Quality in Integrated Systems and Modular Plants

Envirosep's UL Listings demonstrate compliance with applicable safety standards for specific products and assemblies, including packaged pumping systems and industrial control panels.

As a manufacturer of integrated modular equipment, Envirosep combines mechanical systems, electrical components, controls, and automation into coordinated factory-built solutions.

UL-listed equipment helps customers address electrical safety and project compliance requirements while reducing the complexity of coordinating multiple suppliers.

The advantage: Integrated mechanical and electrical manufacturing capabilities supported by recognized product safety evaluations.

ASME U Stamp: Confidence in Pressure Vessel Manufacturing

Envirosep's ASME U Stamp authorization demonstrates our ability to manufacture pressure vessels in accordance with Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code.

For customers, this means pressure equipment is manufactured under established design, fabrication, inspection, and testing requirements.

Whether incorporated into modular mechanical systems or supplied as individual equipment, ASME-certified pressure vessels provide an important foundation for safe and reliable operation.

ASME U2 Stamp: Advanced Engineering for Demanding Applications

Envirosep's ASME U2 Stamp authorization extends our pressure vessel manufacturing capabilities to Section VIII, Division 2.

Division 2 provides alternative design methods, including more detailed engineering analysis and additional fabrication and inspection requirements, making it valuable for specialized pressure equipment and complex applications.

The advantage: Access to both Division 1 and Division 2 pressure vessel manufacturing capabilities through one experienced manufacturing partner

HUBZone Certification: Supporting American Manufacturing and Government Contracting

Envirosep, operating under Tilley Mechanical Technologies, Inc., holds SBA HUBZone certification #59317.

The HUBZone program supports economic development and employment opportunities in historically underutilized business zones. 

For qualifying federal projects, HUBZone certification can provide access to specialized contracting opportunities and support prime contractors pursuing small-business subcontracting objectives.

With manufacturing operations in Georgetown, SC, Envirosep is proud to contribute to skilled American manufacturing and local economic growth.

The advantage: A qualified manufacturing partner offering additional opportunities for federal procurement and government-related projects.

Additional Certifications and Professional Expertise

Beyond these four primary credentials, Envirosep's broader qualifications strengthen our engineering, fabrication, inspection, and system integration capabilities. these include:

NSF/ANSI 61 and Lead-free Listings that support applicable potable water equipment

National Board R Stamp which gives authorization for qualifying pressure equipment repairs and alterations

ASME PP and UM Stamps that gives additional authorizations for applicable pressure piping and miniature pressure vessels

National Board Authorization which supports pressure equipment inspection and certification requirements

TSSA Authorization which supports applicable Canadian pressure equipment requirements

Professional Engineer (PE), AWS Certified Welding Inspection (CWI), Project Management Professional (PMP), and LEED credentials which demonstrates technical expertise across engineering, manufacturing, quality, and project management.

Together, these qualifications support Envirosep's ability to manufacture complex systems for customers with demanding specifications and regulatory requirements.

Why It Matters: The Envirosep Difference
