Double Skin AHUs are generally preferred when stronger casing, insulation and environmental performance are important. Single-skin construction may be suitable for simpler applications.<\/p>\n<h3>Are Double Skin AHUs suitable for pharmaceutical plants?<\/h3>\n<p>Yes. They can be configured with appropriate filtration, cooling, heating, humidity and pressure-control features for pharmaceutical applications.<\/p>\n<h3>Can HEPA filters be installed in a Double Skin AHU?<\/h3>\n<p>Yes. HEPA filtration can be incorporated where required by the application.<\/p>\n<h3>Can a Double Skin AHU be used as a Fresh Air AHU?<\/h3>\n<p>Yes. A Double Skin AHU can be configured for fresh-air treatment and can include appropriate filtration, cooling, heating and humidity-control systems.<\/p>\n<h3>Can Double Skin AHUs connect to a chiller?<\/h3>\n<p>Yes. Chilled-water Double Skin AHUs can use chilled water from a central chiller plant through the AHU cooling coil.<\/p>\n<h3>Does a Double Skin AHU require maintenance?<\/h3>\n<p>Yes. Regular filter, coil, fan, motor, drain, sensor and control-system maintenance is important for reliable performance.<\/p>\n<h3>Does VIPUL HVAC supply Double Skin AHUs?<\/h3>\n<p>Yes.
