Sussex Air Conditioning provides specialist cleanroom air conditioning and laboratory HVAC installation, commissioning, and maintenance across East Sussex, West Sussex, and the wider South East. We design and install bespoke controlled environment systems from conception to completion – working with pharmaceutical, biotech, electronics, research, and healthcare clients who require precise environmental control, regulatory compliance, and long-term system reliability.
Cleanroom air conditioning is a specialist HVAC discipline that goes well beyond standard temperature control. A clean room air conditioning system must simultaneously manage particulate levels, air pressure differentials, air change rates, temperature, and humidity – all within the precise tolerances required by the facility’s ISO classification or GMP grade.
The HVAC system is the most critical element of any cleanroom design. It controls cleanliness and containment for both product integrity and personnel safety. An incorrectly specified or poorly maintained cleanroom HVAC system can compromise regulatory compliance, contaminate sensitive processes, and invalidate test results. This is why cleanroom and laboratory air conditioning must be designed, installed, and maintained by engineers with specific experience in controlled environments – not adapted from a standard commercial AC specification.
We offer a complete cleanroom and laboratory HVAC service covering every stage of the project:
We carry out full cleanroom installation projects for new builds and facility refurbishments. Our scope covers HVAC plant, ductwork design and installation, HEPA and ULPA filtration, pressurisation systems, humidity control, and building management system integration. Every clean room installation is designed to the specific ISO classification or GMP grade required by the facility, and commissioned to the relevant standard before handover.
Laboratory environments have HVAC requirements distinct from both cleanrooms and standard commercial spaces. Fume cupboard extract systems, hazardous materials ventilation, humidity-sensitive research environments, and precision cooling for analytical equipment all require careful specification. We install laboratory air conditioning systems for research facilities, university laboratories, testing environments, and industrial laboratories across Sussex and the South East.
Beyond cleanrooms and laboratories, we design and install HVAC systems for a range of other controlled environments – including temperature-controlled storage, manufacturing environments with strict humidity requirements, and facilities requiring positive or negative pressure containment. If your facility requires a controlled environment installation that does not fall neatly into a standard cleanroom or lab category, contact us to discuss your specific requirements.
For regulated facilities – particularly in pharmaceutical, biotech, and medical device sectors – cleanroom commissioning must be supported by formal qualification and validation documentation. We provide installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) alongside particle count testing, airflow visualisation, and pressure differential verification to support your regulatory submissions.
A cleanroom or laboratory HVAC system requires regular planned preventative maintenance to maintain its classification, ensure ongoing regulatory compliance, and protect operational continuity. We provide laboratory air conditioning maintenance contracts across Sussex covering filter replacement, HEPA integrity testing, airflow measurement, pressure differential checks, and compliance certification.
When a cleanroom or laboratory air conditioning system develops a fault, rapid response is critical – unplanned downtime in a controlled environment can have serious consequences for product integrity and regulatory compliance. Our engineers provide priority callout for laboratory air conditioning repair across Sussex and the wider South East, carrying comprehensive spare parts for all major manufacturers.
For environments requiring exceptionally tight temperature control – server rooms, data centres, analytical laboratories, and calibration facilities – we specify and install precision cooling systems with close-control capabilities. Unlike standard air conditioning, precision cooling systems maintain temperature within tolerances of plus or minus 0.5°C and control humidity to within 1-2% relative humidity, providing the stable environment that sensitive equipment and processes require.
Redundant configurations are available for business-critical environments where system availability cannot be compromised.
We have designed and installed cleanroom air conditioning and laboratory HVAC systems for clients across a wide range of regulated and precision sectors:
We carry out cleanroom air conditioning and laboratory HVAC projects across Sussex and the wider South East. Our service area for controlled environment work includes:
Cleanroom and laboratory HVAC projects are highly specific to each facility’s requirements, classification, and regulatory context. Contact us today to discuss your project – whether you need a new cleanroom installation, a laboratory air conditioning upgrade, ongoing maintenance, or validation support. We will arrange a site visit and provide a detailed specification and quotation with no obligation.
