Critical environments includes a wide variety of specialized space and code compliance requirements. There are many lab types and each has specific rules and regulations that apply. The labs for the entry level uses in higher education chemistry and biology that are looking for ways to ensure student and instructor safety while reducing overall energy consumption. As research has evolved designing for adaptability and flexibility to meet future code requirements has become more important. BSL levels, Vivarium and pharmaceutical applications require much more stringent control of temperature and humidity in the spaces while keeping the manufactured product pure and safe for consumption. Some of the most critical would be CDC experimentation applications with highly infectious diseases where safety and containment are the most important aspects. Our 25+ year knowledge in correctly applying our products deliver value in all critical environment designs.
