Production

The production of Fan coils includes a full production cycle from the manufacture of parts and assemblies, to assembly and testing. At each stage, a detailed quality control is carried out, and the design of the Fan Coils is made in such a way that minimizes the risks of accidental error and human factors. All body parts of the Fan Coils are made of sheet steel by laser cutting. This cutting method ensures maximum quality and precision of the manufactured parts, which ensures ease and ease of assembly.

Standard rolling profiles are not used in the Fan Coil housing, as this often leads to overspending of material and an increase in weight. The volumetric elements are made on a CNC bending machine. Thanks to the precision of laser cutting and bending, we managed to avoid the use of welded elements. All housing elements are assembled exclusively on bolted connections. This gives the Fan Coil an aesthetic appearance and ease of assembly and repair.

To protect against corrosion, all the housing elements of the Fan Coil are powder-coated. This coating has high aesthetic and operational properties. Powder coating does not require additional care and reliably protects the structural elements for the entire life of the Fan coil. Due to the absence of welded joints, each element of the housing is covered with paint separately and only then connected to the overall structure. This approach eliminates the presence of unpainted surfaces, and therefore the risk of corrosion.

All pipes and tanks of the Fan Coil are made of stainless steel. This extends the service life of the critical elements of the Fan Coil under environmental conditions. Pipeline elements are manufactured on a screw-cutting machine and welded in a protective gas-argon environment using a semi-automatic welding machine. After welding, all seams are processed mechanically and etched. This is done to avoid corrosion at the welding sites and to increase the service life of the pipelines.

After assembling the housing, the piping elements are installed. Fan coils work in the open air, which means that a reliable and unpretentious way of sealing the entire internal piping is required. The assembly of the pipeline elements is carried out with the help of special modern threaded sealants, which ensure the reliability of the connection for a long time and do not need to be revised. Such connections are "collapsible" and in case of need for repair and maintenance work, the connections are unwound without much effort.

In parallel, the Fan Coil control cabinet is assembled and the automation elements are installed. The basis of the Fan Coil control is a programmable logic controller (PLC), which contains the programs of the main standard and auxiliary service modes. In addition, the controller monitors the main parameters of the cooling system-temperature and pressure. Inside the cabinet, an optimal microclimate is automatically maintained-heating or cooling is activated depending on the ambient temperature. This protects the automation elements and extends their service life.

The fan speed is continuously controlled by a frequency converter and maintains the optimum temperature of the coolant depending on the ambient temperature. This ensures economical operation and optimal power consumption. The fans are located on top of the Fan Coil and warm air is also released there. In the cold season, warm air can be used to heat production facilities without significantly modifying the Fan Coil and affecting its operation.

For the transport of Fan Coils over short distances, no additional packaging is required. For long-distance transportation, the Fan coil is packed in a stretch film or wooden container to prevent damage and preserve its presentation. All models of the V and W series Fan Coils have standard transport dimensions and are allowed to be transported on conventional roads. The shipment is made by road using a crane or manipulator. On the frame of the Fan Coil there are special slinging loops and limiters for slings, and on the upper belt there are loops for fixing tie belts and cables.

After the final assembly, tests are carried out to check all the operating modes of the Fan Coil. During the tests, various situations that the Fan Coil may encounter in real operation are simulated. Emergency and pre-emergency modes are tested, factory settings and setpoints are debugged and set. Marking and information data in the form of plates and stickers are applied to the Fan coil. Data on testing and acceptance are recorded in the Fan Coil passport, which is an integral part of the technical equipment.
