The Air Handling Units that we manufacture are composed for different types of cells. The frames of the unit cells are made of extruded aluminum carcass. Specially cast aluminum triangle connectors with high elasticity and strength are preferred as connecting elements. Sheets of 1 mm thickness are used for the exterior surfaces and sheets of 0,7 mm thickness are used for the interior surfaces of the Air Handling Units. The exterior surface of the Air Handling Units are made of PVC sheets with European paint and electrostatic oven-dried paint as per request. The interior sheets are made of stainless material of requested quality in Hygienic type Air Handling Units. During the manufacturing process, a polyurethane foam with a density of 70 kg/m³ is injected between the walls in the form of a 20-30 mm-thick layer for units with an air ﬂow rate that is lower than 30,000 m³/h, and as a 40-50 mm-thick layer for units with an air ﬂow rate that is higher than 30,000 m³/h.In addition, rock wool Izocam insulation can be applied optionally. Air tightness is provided by the use of rubber seals on surfaces where the panel is in contact with the carcass. The device is equipped with easily operated service hatches with special hinges and handles that allow servicing in order to provide easy access to the interior structure of the unit. Rubber wedges with springs are used to dampen the vibrations on the extraction ventilators and fans. A special viewing window is located on the service hatches of each ventilation fan and extractor cell.
The fans that are used on the Air Handling Units are double-suction radial fans. The fan shaft bearings are designed as closed type, maintenance-free components with protective rubbers. The low-pressure components of the units utilize forward curved fans with frequently placed blades, while the high pressure devices use statically and dynamically balanced recurvate fans with sparsely placed blades. The fans that are used on the units are selected with a computer-aided special fan program in order to ensure the highest efﬁciency, minimum noise level, minimum energy consumption and the desired amount of air and pressure. On the sections of the fan and the motor that are in contact with the interiors of the cell, special vibration-dampening spring wedges are utilized. This prevents the noise and vibrations from permeating into the frame. Exported ﬂexible connection systems are used for fan outlets and cell connections. The service hatches are designed in a way to ensure that the fans and the motor are easily accessible.
Panel Filter: Panel ﬁlters, which are used as a pre-ﬁlters, are manufactured in a zigzag pattern within cartridges in order to increase the air intake volume in comfort applications. These ﬁlters, which can be categorized as G2, G3 and G4 depending on their dust suppression capacities, can be cleaned with air and are also manufactured in washable types as per request. They can also be manufactured in the form of metallic oil traps in order to retain oil and similar materials. The dimensions of the ﬁlters are standard and they allow easy servicing and replacement. Carbon impregnated types are also available to prevent the odor in the air.
