Telstar designs an innovative HVAC control system that provides automatic regulation in clean rooms

Telstar has designed and developed a new HVAC control system that has been proven to keep the optimum quality of the air by an automatic control mechanism providing steady, stable air changes, without oscillations, in accordance with the GMP environment classification standard corresponding to each room or installation. The new system integrates a particular technology that automatically activates air renovation cycles whilst maintaining pressure, temperature, and humidity variables under stable conditions. The precision in the HVAC control process is an asset that allows the system to reduce the frequency of air renovation cycles to reach the maximum level permitted of particles in the room, in accordance with GMP classification. This is an attribute of the new automatic system that provides the operator with a significant efficiency level as well as over a 40% reduction in energy consumption, depending on the activities carried out in the room and its classification. The power consumption of the new smart clean room HVAC system decreasing the room air changes, has proven to guarantee the air quality in accordance with the room classification following the regulations stated in EU GMP Annex 1 and ISO Standard 16644-1.

The new HVAC control system driven by an advanced PLC is connected to a particles counter and an air handling unit adapted by Telstar to the new installations and clean rooms. The innovative system, which offers flexibility to be adapted to a conventional system in operation, can be adjusted to the specific needs of each room and be customized by the operator using a control touch screen to define many parameters, for example security margins and control mode. The innovative control system has been validated by GAMP 5 which, promoted by the International Society for Pharmaceutical Engineering (ISPE), guarantees a good automated manufacturing practice in the pharmaceutical industry.
