Fire and Smoke Dampers play a crucial role in the safety in ducting connected to a heating, ventilation and air conditioning system. They prevent the spread of fire and smoke through ductworks. Fire and smoke dampers are known as shut off dampers this is because the blades inside the metal panels will close and allow no additional air to flow through - the blades are forced to shut, this happens because of a fusible link which is set to trigger at It is a legal requirement to have these dampers tested at a minimum once every two years. Failure to do so can result in a fine, prison sentence and closure of business premises until rectified. AJS offer this essential fire safety service of a full fire & smoke damper testing and certifications with nationwide coverage. All test are carried out by fully qualified and trained technicians. Testing will include: Identify and locate each fire damper Retrofit access doors if any of these are inaccessible Carry out fire damper test

AD SMALL PREMIUM evaporative air conditioners for evaporative air conditioning in industrial, commercial, agricultural or livestock premises Evaporative coolers are a natural cooling system that uses water as a cooling element. Its basic operating principle is to suck in the outside air and pass it through some cooling panels moistened with water. Once the air passes through this panel, it cools and increases its humidity. Once this process has been carried out, the air is propelled inside the premises to be air-conditioned and, based on the appropriate renovations and extraction of air, a comfortable comfort temperature and adequate indoor air quality are achieved for people. AD SMALL PREMIUM evaporative air conditioners, develop an air flow from 5,760 m3/h to 17,145 m3/h with an available pressure at a maximum flow of 100 Pa, its cooling capacity is suitable for premises from 67m2 to 255m2

The FDA12 round fire dampers are designed for use in general ventilation systems to seal off smoke and fire between adjacent fire partitions. The fire dampers are classified according to EN 135013+A12010P (Fire classification f construction products and building elements). The fire resistance was tested as per PNEN 136622001P (Fire resistance tests for service installations Part 2 Fire dampers). The entire manufacturing process meets the requirements of EN 156502010. The FDA12 fire dampers can be installed in horizontal and vertical fire partitions to provide fire resistance of EI 120 (ve ho i↔o) S (which may depend on the actual fire resistance of the partition). The fire dampers are available in the nominal diameter sizes DN100, DN125, DN160, DN200, DN250, and DN315. All fire dampers have a pull spring control gear and a fusible thermal trip (in FDA12T) or a returnspring actuator coupled with a thermal trip (in FDA12M).
