The Angstrom Group delivered a new dry room for lithium battery production, within a new scale-up facility for Anaphite. Anaphite is a chemistry company developing CNT enhanced cathode powders that can be used to produce dry coated electrodes for low-cost, high-performance Li-ion batteries. To disregard any effects of moisture affecting materials, Anaphite needed an ultra-low dewpoint air supply that could be driven down to minus 75°Cdp, with a target return of at least minus 40°Cdp measured at the point of air return.
Dry room with combined airlock gowning area
CFD airflow analysis ensured even distribution of horizontal airflow
Multi-rotor system to quickly drive the dry room down to specification
Ultra-low dewpoint air supply that can be driven down to minus 75°Cdp
Fully sealed panel system combined with fully welded stainless steel providing an ultra-low air leakage rate
HEPA filtration to deliver ISO 14644-1 Class 7 compliant air within the main area
The main requirement for the dry room was the target dew point and the size, but Anaphite also needed the dry room to be modular. As a start-up, demands, and requirements can soon change, so a modular and relocatable design gives Anaphite the flexibility to adapt to unforeseen changes. The dehumidifier unit, amongst other elements of the project build, is movable, satisfying the need for modularity.

The Angstrom Group delivered a new 24,000 square foot clinical manufacturing cleanroom facility for the Azzur Group in Morrisville, NC. Azzur Cleanrooms on Demand™ (COD) offers a hybrid early-phase manufacturing model geared specifically to the challenges early-phase manufacturers face when it comes to starting up and scaling out. The need for clinical manufacturing capability and lengthy facility design-build timeframes are both barriers that COD can remove.
24,000 square foot COD facility in Morrisville
24 independent cleanroom suites
Each suite has a Material Airlock (MAL), Personnel Airlock (PAL), Cleanroom and Exit PAL
Shared entry and exit corridors provide easy access to and from each cleanroom
Locker room and changing area
Material airlocks provide a path for large equipment to enter the suites via the GMP warehouse
All cleanroom suites are controlled and monitored by state-of-the-art systems which are tied into the building management system.
This is the first COD facility Angstrom has delivered for the Azzur Group and the 4th in the Azzur COD group. In June 2023, a grand opening ceremony was held for Azzur Cleanrooms on Demand™ Raleigh, and Angstrom Technology is currently under construction on Azzur COD facilities in Devens, MA and Alameda, California.

Angstrom Technology delivered a new 1,700 square foot OEM packaging cleanroom facility to a global supplier of single-use components.
The global company needed to expand to accommodate the increased growth of its business to the medical and bioprocess industries. This expansion of the company’s pick and pack process allows the company to increase capacity, and reduce lead times for customers.
OEM packaging cleanroom highlights
1700-square-foot, state-of-the-art ISO Class 8 cleanroom
Designed for the packaging of single-use components to serve the medical and bioprocess industries
Gives customers the confidence and peace of mind that the components that are manufactured in a cleanroom are always opened and repacked in a similar environment
The cleanroom features ten workstations designated for the scale counting and repacking process
Optimized layout to facilitate the movement of bagged parts into the cleanroom via curtained pass-through openings for weighing and repackaging
Installed within a temperature-controlled warehouse, pre-cooled supply air is pulled through terminal HEPA filtration to provide a controlled environment suitable for the process

The Angstrom Group delivered a new 3,600 square foot cleanroom facility for R&D at a solid-state battery manufacturing facility. Delivered from order to handover in just 6 months, this cleanroom was built between February and August 2021. This schedule was achieved, despite COVID-19 restrictions and disruption, through high levels of communication and collaboration.
Designed and built in 6 months – from order to handover
8 zones – process-built layout with 3 process areas and 5 ancillary zones
Zones achieve ISO classes 6-8, plus 20±1°C and 45%RH±10%RH in all classified areas
Construction was undertaken during the COVID-19 pandemic
Daily project management meetings and weekly steering group meetings with a multi-disciplinary team
The Site Project Lead, gave weekly tours to the CEO, CFO, and CSO — to keep senior management up to date on the progress at the site
Eight zones provide segregated spaces for various process activities — three main process areas and five ancillary zones.
These batteries are created on the surface of a wafer by layering semiconductive materials in intricate patterns. Each layer is part of a step and it takes over 60 steps to achieve the exact electrochemistry. Batteries needs to move back and forth between the zones, so an optimised layout was critical to achieving people and product transfer.
You enter the cleanrooms through an ISO class 8 changing room into the ISO class 7 dry etching zone. There are then three routes. Either progress into the ISO class 8 chase zone, the ISO class 6 photolithography (wet etching) zone, or through the ISO class 7 tool 1 processing zone into the ISO class 8 semi cleanroom. From the semi cleanroom, you can access the unclassified corridor and cleaning room. Some machinery crosses zones and so apertures were created to profile walls around the specialist equipment.

The Angstrom Group delivered a 20,000 square foot biopharma cleanroom within a new manufacturing facility. This project was built across 3 phases as part of a two-year $1.5bn global expansion plan for a global life sciences company. The site manufactures mixer bags, flow kits, and tubing assemblies — including COVID-19 vaccines.
ISO Class 7 with elements of GMP qualification, through DQ, IQ, OQ, and PQ
HVAC system controls temperature and humidity with terminal HEPA filtration providing particulate control with 99.99% efficiency at 0.3 microns
Temperature and humidity control, flush envelopes, air showers, vision panels, swipe card entry, and intercom systems
The speed of delivery was a key factor in our appointment – phase 1 was built in 9 months
On-site management team maintained a consistent presence on-site
Air return columns withdraw air from 4 sides, so when any heat or particulate is generated from processes, they are pulled straight out of the room
The site will help to increase our client’s global manufacturing capacity for single-use products by 20%.
