In general, all mechanical devices that are installed under the false ceiling of the building, need a door to visit and access for periodic services or repairs. Therefore, inspection doors are used to access these equipments. The aluminum fan coil inspection door, which is one of the types of access and inspection valves, is used for ventilation devices such as fan coils and split ducts.

If the return air suction of these devices is through the return channel, these inspection doors do not need a grill or groove, but if the return air suction is from under the device, the inspection door needs a grill or groove. For these cases, Shahrokhi Technical Institute offers different solutions in different models.

Fan coil inspection doors are divided into two general categories: Siemens lock and weighted fan coil inspection doors. In the lock and hinge models, grills are not considered by default, but there is the ability to add a mesh grill with linear valves and an egg basket valve on them. Weight models are also divided into two single-groove and two-groove products, which are selected according to the ventilation rate of the device and decorative taste. In these models, the door is separate from the valve frame and the door is placed on the frame as a weight.

Single-groove and double-groove opening under the fan coil valve are also produced by combining two models of weight and lock and hinge. This model is used when the distance from the ceiling to the device is not enough and it is not possible to separate the weighing inspection door. Therefore, both the beauty of single-slot and double-slot inspection doors is achieved, and the limitation of the space above the inspection door to the machine is eliminated.

Final cover and valve installation under the fan coil

Like most of the valves produced in this collection, an automatic screw is used to install this product, and instead of a screw (treasure), it is created before applying the color coating on the valve frame. It is better to install this valve on a wooden or metal frame to be sure, because if the valve is installed directly on the plaster, there is a possibility of the valve loosening over time. In order to install this valve on false walls with dry materials (Kenaf, etc.), it must be ensured that special false ceiling profiles are used all around the opening of the valve for strength and reliable connection of the valve to the wall.

Electrostatic paints are used for the final coating of these valves. After carrying out the production steps to remove any grease dust and other particles, the valves are acid washed and after applying the desired undercoating (it is selected according to the type of metal and a different coating is used for each type of metal) it is placed on the spraying camwire line and the furnace. they take. At this stage, the color needed by the customers is sprayed on the surface and the valves enter the oven for the baking stage. In the baking stage, the temperature of the oven (the temperature graph that the valve experiences) is very important, and incomplete baking has an adverse effect on the final coating. It should also be kept in mind that overcooking the paint will change the color shade and make it dull.

On 12/16/1390, Shahrokhi Technical Institute succeeded in receiving the license to use the mandatory national standard mark of air valves for the first time in Iran, and according to the decree of the National Standards Department of Iran, it started working as a partner laboratory of the Standards Department. All products produced in Shahrokhi Technical Institute, including this product, have the ability to perform various types of tests in the presence of supervisors and customers in accordance with standards 7693 and 7695 for pressure drop, launch length, flow distribution pattern and other relevant parameters; It should be noted that the function of the air distribution terminal and the valve under the single slot fan coil is different.
