Product Categories
The products produced by KOVENT-KLIMA OOD are designed and manufactured in accordance with the Law on the technical requirements for products and the safety and health requirements of the Ordinance on the essential requirements and assessment of conformity of machines, introducing the introductory Directive 2006/42/EC.

Axial fans
Axial fans are designed to transfer a large volume of air masses with a relatively small increase in pressure. They are suitable for applications where airflow resistance is minimal, such as general ventilation, engine cooling or air conditioning systems.

Centrifugal fans
Centrifugal fans are designed to transfer a larger volume of air masses at a large pressure rise. They are extremely useful in industrial processes such as material transportation in dust collection systems, combustion air for burners, drying and cooling, general ventilation and air circulation.

Local dust collectors
Local dust collectors are designed to capture dust and particles released during the processing of various types of materials. They are used for equipping circular saws, edging machines, grinders and other carpentry machines. Help to maintain clean and safe conditions around dust generating machines in workshops and factories.

Air-heaters
Air heaters designed to operate in areas with explosive atmospheres are used for heating production premises, warehouses, garages and other objects where there is an explosive environment.
Our services
We are open to various forms of cooperation. KOVENT-KLIMA OOD offers services and fulfills orders according to the specific needs of the recipient or provided documentation. We have production facilities, technological capabilities and equipment for:

Laser Cutting
Laser cutting allows production of various in size, complexity and design elements from metal or sheet metal. Machined surface has sharp cut edges and corners of the workpiece, as well as very accurate contours.
We work according to customer's drawings or with those drawn up by our engineers. Price is formed depending on the kind of material, thickness of the sheet, dimensions of the workpieces and their quantity.
The MSF 3001.15L fiber laser cutting machine is equipped with two movable worktables with dimensions of 1500 x 3000 mm.
Maximum cutting thicknesses for different materials are:

Plasma cutting
Process of plasma cutting is a thermal cutting method. The plasma arc can cut a very wide range of electrically conductive alloys, including common carbon and stainless steels, aluminum and its alloys, nickel alloys and titanium. Initially, the method was developed for cutting on materials that could not be cut satisfactorily by an oxy-fuel process.
The disadvantage of plasma cutting is that it results in a wider notch. Plasma cutting can lead to the formation of slag or re-solidified metal at the lower edge of the cut, beveling of the cut and tapering of the holes.
Kovent-Klima OOD has a digital-program cutting machine with a Hypertherm HSD130 plasma source and performs plasma cutting of details up to 1500 x 3000 mm with a positioning accuracy of 0.1 mm.
Maximum cutting thicknesses for different materials are:

Bending
Metal bending is a process in which metal is deformed when a force is applied to the object, causing it to bend at an angle and form the expected shape.
The difference between Press-brake bending (bending of metal sheets at an angle) and Roll bending (bending of metal sheets at a radius) is the radius of curvature.
KOVENT-KLIMA OOD possesses:
Hydraulic press-brakes with computer numerical control (CNC) - BAYKAL APHS 2100 x 40t. The machine technical specifications are:
Three-roll sheet bending machine (Roll bending machine):

Guillotine cutting
The cheapest and most cost-effective method of cutting and shaping sheet metal is guillotine cutting. It is used to produce details and blanks with straight sides and different shapes – rectangles, triangles, squares, etc.
Guillotine cutting with numerical program control is recommended for sheet material that should be precisely and inexpensively cut. Our BAYKAL RGS 2060 x 4 electromechanical guillotine guarantees precision and cut quality.
The material required for the execution of the order can be provided by the customer or by KOVENT-KLIMA OOD.
Working range:
Stamping
Stamping is a type of cold forming process that is widely used in the metal forming industry and other tasks that require high force. Hydraulic presses are extremely functional and capable of meeting the needs of most industrial environments.
Precision sheet metal stamping is a highly efficient solution suitable for mass production, providing high-quality metal parts for aerospace, automotive, medical equipment, electronics, industrial and urban infrastructure. We have a double-acting hydraulic deep drawing press ELMALI EHSP-250.
Technical specifications:

Balancing
Balance machines are used to balance rotating machine parts such as rotors for electric motors, impellers of fans and pumps, turbines, disc brakes, disc drives, propellers, pumps, spindles, gears and others.
Well-balanced parts increase the service life and reduce the vibration levels of the machines. Improve the speed, performance and efficiency of the machines on which they are installed.
The balance machine HM 30, manufactured by SCHENCK, is combined with a measuring instrument CAB 820, ensuring high accuracy of dynamic balance.
Possibility of correction:
Balance detail size:
The cost of the balance is formed on the basis of the type of balance (in one or in two planes), directly depending on the diameter and/or weight of the rotor.
Field balancing
The SMARTBALANCER provides extensive possibilities for field balancing. With this device, rotors of almost any size and weight can be balanced quickly, cost-effectively and accurately, in the installed state and therefore without having to disassemble the machine.

Welding
Welding is a process through which a monolithic joint is obtained from welded parts. Between the welded parts, atomic-molecular bonds are obtained, ensuring the continuity of the structure in the weld zone.
KOVENT-KLIMA OOD has MIG/MAG welding machines, as well as a spot welding machine. The price is determined individually for each order.
