HVAC Validation of Controlled Environments

Many products and processes require the control of airborne contamination during manufacturing and processing include aerospace, food & drink, healthcare, medical devices, microelectronics, pharmaceutical, biotechnology and automotive industries.

Control environments require continuous testing, monitoring and routine re-qualification to ensure compliance with the controlled low levels of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapours, sometimes using separate devices such as Clean Airhoods, Gloveboxes, Isolators and mini environments.

Some HVAC systems also control temperature, pressure and humidity using ionizers to prevent electrostatic discharge problems. All these systems require routine re-qualification, testing and monitoring to provide evidence of continual compliance with the legislation.
