How should the air vents and pipe joints of air-conditioning boxes be protected before leaving the factory for transportation?

Before the air-conditioning box leaves the factory for transportation, the air inlets, coil joints and other exposed interfaces should be sealed and mechanically protected suitable for transportation conditions to prevent foreign matter, moisture and collision from entering the equipment. Packaging must not only cover openings, but also avoid transmitting pressure to fragile joints, and specify inspection and removal requirements upon arrival.

Arrange protection methods by interface type

The large air vents need to prevent foreign matter and rainwater from entering, the water joints need to protect the threads, flanges and sealing surfaces, and the extended sensors or actuators need independent anti-collision measures. Temporary sealing should be fixed reliably and identifiable, and should not use loose materials that can easily fall into the equipment and be difficult to count and remove after arrival.

The air openings must be closed, protected from rain, and the transportation of foreign matter must be controlled; the pipeline interfaces must be anti-collision, anti-pollution, and the connection surfaces must be kept intact; exposed accessories must be fixed, buffered, and have necessary independent packaging and markings. The protection objectives of the three types of interfaces are different and cannot be covered with the same film. Please refer to the relationship between the size of the air outlet and the mode of transportation.How to choose between combined and integrated air conditioning boxes?。

The sealing material must be fixed reliably

Vibrations and bumps during transportation may cause the temporary cover to shift or fall off. The sealing parts should be able to withstand the wind pressure and vibration during transportation, the edges should be firmly fixed, and they should be easy to be completely removed after arrival. If tape or film is used, materials should be selected that will not leave adhesive residue that is difficult to clean on the surface of the box, and should avoid blocking equipment markings and hanging points.

The closure itself should not become a new source of foreign matter. If materials such as foam and cardboard break during transportation, the fragments may fall into the box, making cleaning more difficult. Identifiable, inventoryable, and completely dismantling are three points that need to be considered simultaneously when choosing a sealing method.

Do not transfer pressure to fragile joints

The threads and flange surfaces of the coil water joint cannot withstand the weight of the entire machine or the extrusion of the packaging. When hoisting and stacking, the packaging structure should transmit the load to the box frame or base, rather than through pipe joints or air outlet flanges. The extended pipe sections and sensors should have independent supports or protective covers to avoid stress deformation during loading and unloading.

The use of transportation lifting points should also distinguish between temporary lifting and long-term suspension. Please refer toCan the loading and unloading lifting points and operating lifting points of the air-conditioning box be mixed? . Units transported in sections should also pay attention to the protection of the connection surface. Please refer toHow to identify the assembly sequence for segmented transportation of combined air-conditioning boxes?。

What to check when handing over

Record the appearance of the packaging, interfaces and boxes. If any damage or water intrusion is found, evidence should be retained in a timely manner and handled according to the handover process. Temporary protection should be removed before the corresponding installation process. After removal, check whether the interior is clean. The equipment cannot skip inspection of openings and joints just because the outer packaging is intact, nor can any transportation seal be left behind after connection.

During the inspection, you can check the number and location of the sealing parts against the packing list to confirm that nothing is missing inside the box. If the sealing material is found to be damaged or missing, check whether foreign matter or moisture has entered the corresponding opening. For internal cleaning, please refer toWhat conditions need to be checked before the air-conditioning box is turned on for the first time?。

Open storage and long-distance transportation require additional considerations

If the equipment needs to be stored in the open air on site for a period of time, or it may encounter rainfall during transportation, the rainproof requirements for sealing and packaging should be increased accordingly. The top of the box, the air vent and the access door are places where rainwater can easily enter. It is necessary to confirm that the packaging is complete and that drainage does not accumulate in the blocked areas. The packaging status should also be checked regularly during long-term storage.

On-site storage conditions should be informed to the manufacturer before shipment to facilitate confirmation of packaging protection level and on-site inspection requirements. If the storage time is long, please refer toHow to determine the maintenance cycle of air conditioning box according to the operating environment? According to the inspection ideas in the inspection, the packaging and sealing status are included in the inspection.

Aili industrial supporting equipment

Explaining the transportation route, whether it is open-air and on-site storage time to Aili Industrial will help confirm packaging protection and on-site inspection requirements. Aili Industrial can confirm the protection methods of air inlets, coil joints, exposed accessories and box structures at the manufacturing stage; the manufacturing end covers sheet metal, complete machine assembly and air filters. Blocking positions, hanging points and packaging markings can be corresponding in the same set of delivery materials. The protection methods of non-standard interfaces can be adjusted according to transportation conditions.

Product form can be viewedAir handling unit andFan box page; clean air supply package can be combinedFFU fan filter unit andEFU equipment end fan filter unit verification; terminal particle filtration can be combinedHEPA/ULPA filter confirmation; when it comes to gaseous pollution control, you can communicate separatelyChemical filter solutions. The specific packaging method, protection scope and delivery requirements still need to be verified based on the corresponding configuration information and transportation conditions. The actual results are subject to on-site inspection and on-site leak detection results.

Related questions and answers

Is it enough to cover the air outlet with film?
not enough. It must also be fixed reliably, protected from rain and foreign objects, and prevent the sealing parts from being damaged or falling into the box during transportation.

Do pipe joints need to be protected individually?
need. The threads and flange surfaces cannot bear the weight of the entire machine or the extrusion of the packaging, and should be independently protected so that the load is transmitted to the box frame rather than the joints.

Can Aili Industrial help confirm transportation protection requirements?
The sealing and packaging method can be determined based on the transportation route, storage conditions and interface form. The specific plan needs to be confirmed according to the project conditions.
