Air handling unit (ahu) 8 different models which provide required humidity and temperature by conditioning air volume in wide ranges. Standard series Application area: business centers, schools, hospitals, factories, hotels and restaurants. 8 different models which provide required humidity and temperature by conditioning air volume in the range of 3000m¦/h and 100.000 m¦/h. The framework which is formed by combination of aluminum frames, which are connected specially, with plastic and aluminum comers. Boards which are made up of double skilled galvanized iron in a standard way. Polyurethane insulated panels, which are 30 mm in thickness, for thermal and acoustic insulation in a standard way. Standard accessories; Filter chambers; chamber design which provides easy mounting and de-mounting in filters and filters with different productivity levels on demand. Heating and cooling coils; seamless cooper tubes. In heating coils, 4 options: warm water, vapor, hot water, electrically heated; in cooling coils, 2 options: chilled water and dx (direct expansion). Dampers; rigid aluminum frame in multi airfoil structure which is the least resistant against airflow. Rubber gaskets which reduce air leakage through blades to the minimum level. Fans; statically and dynamically balanced aspirators and ventilators in double inlet belt driven centrifugal type. Forward curved fans in systems with low, medium and high duct pressures, . Optional accessories; Gonka vapor humidifier, standard vapor cylinder, immersion electrodes, stainless vapor distributor and microprocessor control unit. Mufflers which are made up of coulisses to provide required sound holding capacity. Plate heat exchanger or heat recovery wheel for recovery of the heat emitted with exhaust air. Electrical board. Frequency converter Depends on the size, model and chambers
