Turnkey cleanroom, HVAC, equipment and MEP solutions.
Accord delivers the complete cleanroom, HVAC and MEP package under one roof, engineered around your process, manufactured in our own plant, installed and qualified by our teams.
Four disciplines held in a single contract
Most facility problems appear at the seams between trades, where the panel contractor, the HVAC contractor and the electrical contractor each assumed someone else owned the interface. We remove those seams.
Cleanroom Envelope
Modular wall panels, walkable ceiling systems, GMP doors and view panels, epoxy and PU flooring, pass boxes and air showers. This is the physical boundary that holds your classification.
Explore cleanroom envelopeHVAC & Air Systems
Air handling units, dehumidification, chillers and chilled-water piping, GI / Aluminium / SS ducting, HEPA terminal filtration, VFDs and controls. This is the system that actually creates the classification.
Explore HVAC systemsCleanroom Equipment
Laminar and reverse laminar airflow units, biosafety cabinets, static and dynamic pass boxes, air showers, gowning benches, stainless-steel furniture and accessories, standard or tailor-made.
Explore equipmentTurnkey MEP & Validation
HVAC power panels and MCC, control panels and PLC, GMP light fixtures, cleanroom wiring, earthing and safety, utility and process piping, pump houses and cooling towers, plus full DQ, IQ and OQ.

Classification we design and validate to
Facilities engineered to ISO 14644-1 and FS 209E, using turbulent-dilution or unidirectional airflow according to the risk in each room.
| ISO 14644-1 | FS 209E Class | Max particles ≥0.5 µm / m³ | Typical ACPH | Typical Application |
|---|---|---|---|---|
| ISO 5 | Class 100 | 3,520 | 240–480 (unidirectional) | Aseptic filling, critical exposed product zones |
| ISO 6 | Class 1,000 | 35,200 | 150–240 | Sterile support, high-risk compounding |
| ISO 7 | Class 10,000 | 352,000 | 60–90 | Core manufacturing and processing suites |
| ISO 8 | Class 100,000 | 3,520,000 | 20–40 | Secondary operations, packing, material airlocks |
Indicative industry values. Final ACPH is derived from heat load, occupancy and process during design qualification.
Design parameters we control
- Air changes per hour (ACPH) per room
- Pressure cascade, typically 10–15 Pa steps
- Temperature and relative humidity setpoints and tolerances
- Staged filtration: pre → fine → HEPA H13 / H14
- Airflow patterns and recovery time
- Contamination and cross-contamination control

Validation Planning
Protocols and acceptance criteria agreed before fabrication.
Equipment Construction
Factory manufacturing of panels, doors, AHUs and equipment.
Factory Testing
FAT completed and signed off before dispatch to site.
Shipping & Installation
Site erection executed by our own installation teams.
Site Testing
SAT, IQ and OQ execution with your quality team.
Documentation
Complete validation dossier compiled and handed over.
Training & Commissioning
