CLEANROOMS

Cleanroom mechanical contractor in Connecticut.

ISO 5 through ISO 8 environments built and maintained by crews that understand pressurization, particle control, and what certifiers look for at testing.

Cleanrooms run on airflow, pressurization, and filtration. We design-assist, fabricate, and install the mechanical scope that holds the classification, then we stay on after handoff to maintain it.

Our biotech, pharma, and semiconductor clients in CT use us because the install gets sequenced with validation in mind. Less rework at commissioning, fewer surprises at certification.

Pressurization cascades

Room-to-room differentials tuned with airflow stations and BAS coordination.

HEPA terminal housings

Room-side replaceable terminals installed for access, with scan testing coordinated through your certifier.

Stainless duct in-house

Welded stainless duct fabricated in our Middlefield shop for sterile and pharma rooms.

Process gases & DI water

High-purity utilities tied into the envelope without compromising the classification.

Phasing around production

Tie-ins planned to keep adjacent classified spaces in spec while work happens.

Validation coordination

We work alongside your QA, validation firm, and certifier so commissioning doesn't slip.

What we deliver

  • ISO-classified cleanroom HVAC systems
  • HEPA filtration and terminal hood installation
  • Exhaust and makeup air balancing
  • Negative and positive pressure zoning
  • CRAC and CRAH unit installation and modification
  • Rooftop tie-ins and duct drops
  • Humidity and temperature control tuning
  • Clean build practices and documentation

We coordinate with your engineers, commissioning agents, and certifiers so the space is ready for compliance review and certification.

Industries we support

  • Compounding pharmacies
  • Life sciences labs
  • Biotech and medical device manufacturing
  • Research and university labs
  • BSL and BSL-3 facilities
  • Clean packaging and sterile production lines

Need a refresher on terms like HEPA, CRAC units, or USP 797? Check the glossary.

Bring us in early.

The earlier we're on a project, the more we can value-engineer, prefabricate, and de-risk the install. Let's talk specs, timeline, and budget.
