Professional Services
Comprehensive cleanroom engineering services covering the full project lifecycle
Cleanroom Design & Consulting
From feasibility study to 3D BIM modelling β our engineers design cleanrooms that balance performance, compliance, and budget.
Our Approach Every project starts with a detailed User Requirements Specification (URS) workshop. Our HVAC designers, process engineers, and project managers collaborate with your team to translate operational needs into a compliant, cost-effective cleanroom design. What We Deliver Feasibility assessment and site survey Air-change rate (ACR) and pressure cascade calculations 3D BIM modelling with Revit / AutoCAD MEP P&ID diagrams and equipment schedules ISO 14644 classification strategy Construction timeline and phased commissioning plan Standards We Follow ISO 14644, EU GMP Annex 1, FDA 21 CFR Parts 210/211, ISPE Baseline Guides, and ASHRAE 170 for healthcare applications.
HVAC System Integration
Precision air-handling systems engineered for temperature Β±0.5 Β°C, humidity Β±3% RH, and multi-zone pressure control.
Integrated HVAC Solutions Cleanroom HVAC is not ordinary HVAC. We design and install dedicated air-handling units (AHU), return-air systems, chilled-water piping, and BMS controls that maintain your critical parameters 24/7 β with built-in redundancy for the most demanding production schedules. Core Capabilities Custom AHU design with HEPA supply, activated-carbon, and chemical filtration stages Temperature control: Β±0.5 Β°C (standard) to Β±0.1 Β°C (precision) Humidity control: Β±3% RH (standard) to Β±1% RH (precision, with steam or ultrasonic humidification) Positive/negative pressure cascade across multiple zones VFD-driven supply and exhaust fans for energy optimization BMS integration: Siemens, Honeywell, Schneider, or open BACnet protocol Energy Recovery Plate or rotary heat exchangers recover up to 70% of exhaust-air energy, reducing HVAC operating costs in high-air-change cleanrooms by 30β40%.
Installation & Commissioning
Turnkey on-site installation by our 120+ skilled team β from steel structure to final HEPA filter integrity testing.
Full-Scope Installation Our in-house installation teams handle every trade: structural steelwork, panel erection, HVAC ductwork, piping, electrical, BMS wiring, flooring, and finishing. Single-source responsibility eliminates coordination gaps and accelerates handover. Installation Process Pre-construction meeting β Detailed method statements, RAMS, and quality plan Structural works β Steel framing, raised floors, ceiling grids Envelope β Sandwich panel walls, ceilings, doors, windows, coving MEP first fix β HVAC ductwork, pipework, electrical conduits MEP second fix β FFU/HEPA installation, lighting, power outlets, controls Sealing & finishing β Epoxy flooring, silicone sealing, cove application Commissioning β HVAC balancing, DOP/PAO HEPA integrity test, airflow visualisation Quality Assurance ISO 9001:2015 quality management system applied throughout. All welding, ductwork, and panel installation documented with photographs and inspection reports.
Validation & Performance Testing
IQ/OQ/PQ protocols and ISO 14644 classification testing β particle counts, airflow, pressure, temperature, and humidity mapping.
Comprehensive Validation Validation is not just a formality β it is the proof that your cleanroom performs as designed. Our validation engineers follow GAMP 5 principles and provide complete IQ/OQ/PQ documentation packages accepted by regulatory auditors worldwide. Testing Scope Particle count testing β ISO 14644-1 classification (at rest and in operation) HEPA filter integrity β DOP/PAO aerosol challenge per ISO 14644-3 Airflow velocity & uniformity β Anemometer traverse per ISO 14644-3 Pressure differential β Multi-point manometer mapping across all zones Temperature & humidity mapping β 24-hour data-logging at grid points Recovery test β Time to return to classification after contamination event Sound level measurement β Compliance with occupational limits Lighting level measurement β EN 12464-1 compliance Deliverables Bound validation report with raw data, calibration certificates, deviation management, and summary of compliance. Re-qualification schedules recommended per ISO 14644-2.
Maintenance & Recertification
Annual recertification, preventive maintenance contracts, and 24/7 emergency support to keep your cleanroom compliant.
Preventive Maintenance Programs A cleanroom is a living system that requires regular attention. Our maintenance contracts ensure filters are changed on schedule, HVAC performance stays within spec, and you remain audit-ready at all times. Service Inclusions Semi-annual or annual HEPA filter integrity retesting Pre-filter and medium-filter replacement HVAC system inspection: belts, bearings, coils, condensate drains BMS sensor calibration verification Differential pressure gauge checks Door interlock and air-shower functional testing Detailed service report with photographic evidence Emergency Response 24/7 hotline with guaranteed 4-hour telephone response and 24-hour on-site response for critical facilities. Spare-parts consignment stocking available for key clients. Recertification Full ISO 14644 classification retesting at intervals required by your quality system β typically every 6 or 12 months. We supply updated validation reports and certificates.
