Heating, ventilation, and air conditioning (HVAC) system consumed huge energy. Especially chillers, hot water generation, boiler operation consumed lots of energy. We can understand the qualification requirement from the table 1. Loosing microbial controls is very high due to unplanned shut down. An efficient design and qualification approach can help firm for long run. […]
The control and monitoring systems are considered the core of the environmental control system. The final performance of the environmental control system can be evaluated only after these have been validated. PQ protocols covering this system, in general, include the performance challenges for the all the components of the environmental control system described in the […]
Building Management System (BMS) is monitor and control the parameters of HVAC system like temperature, relative humidity and air quantity to maintain a controlled environment.
There are different sizes and types of Air Handling Units. Some will fit in a closet or within a ceiling space, while others will require a mechanical room or will need to be placed on the roof of a building. Within all of them, however, there is at least one fan and one method of […]
An essential element in ensuring aseptic conditions is the maintenance of HEPA filter integrity. Integrity testing should be performed at installation to detect leaks around the sealing gaskets, through the frames or through various points on the filter media. Thereafter, integrity tests should be performed at suitable time intervals for HEPA filters in the aseptic […]
I. PURPOSE OF VALIDATION High-quality water and air are essential for the manufacture of pharmaceuticals. Water is the most commonly used raw material in pharmaceutical manufacturing; it is indirectly used in the manufacture of all dosage forms for cleaning manufacturing equipment, and is also used as a major component which constitutes injectable products. It is […]
Introduction: Heating, ventilation and air-conditioning (HVAC) play an important role the manufacture of quality pharmaceutical products. A well designed HVAC system will also provide comfortable conditions for operators. HVAC system design influences architectural layouts with regard to items such as airlock positions, doorways and lobbies. The architectural components have an effect on room pressure differential […]
About HEPA (High efficiency particulate air) High-Efficiency Particulate Air or HEPA is a type of air filter. It is a type of filter which has high efficiency to filter out about 99.997% that is why they are termed as High efficiency particulate air filter,HEPA filters are made up of a mesh of fiber glass […]
