Aerotecnica Coltri Spa exports 90% of its production to 60 countries. In light of this, the company can boast a global vocation and is an internationally recognized “brand”. Aerotecnica Coltri Spa is based in Desenzano del Garda (Brescia) and manufactures high-pressure compressors that can be used in different sectors: from the diving industry to fire departments, from hunting to target shooting weapons, from natural gas to industrial gas.
Production and export
•Production cycle – The company has an in-house workshop that processes and obtains nearly all the mechanical components from die casting or bars to drawn bars using high-tech CNC tool machines and horizontal machining centres. The production process starts from a foundry that provides cast iron and aluminium for cylinders and casings. The company’s palletized horizontal machining centre allows obtaining high-quality products. Highly qualified personnel run these machines and oversee the robotic cells, too. The company consists of four interconnected facilities, and a separate facility is reserved to the assembly of the pumping units of the major machine line. Today, a project involving the company’s patented nickel and silicon galvanic coating cylinders is also being developed. •Quality control and tests – All tests are run in the metrology room in order to maintain the high quality of the production while meeting the required parameters. The technical department constantly runs random checks using measurement tools ranging from simple gauges to DEA measuring machine, a system that serves as a highdefinition scanner detecting any dimension difference (in microns) of the analysed item, checking the tolerance, and providing information on any improvements to be applied to the entire production. A trio of robots combined with automated CNC machines are also in use: these fully automated robots comprise an island that needs no human supervision.
•Global export – 90% of the company’s production is exported to 60 countries. In some countries, the distribution network involves the acquisition of companies that operate in the machine maintenance industry, such as Coltri Sub Asia Pacific in Bangkok, in the free-trade zone for East Asia; and a company in Sharm El Sheikh for the Middle East and Egypt. Moreover, a network of dealers is also present in almost every country with spare parts warehouses for both routine and special maintenance.
The compressors
The company offers a wide range of breathing-air and technical gas compressors from the small portable compressor of the Mch6 series, with a flow rate of 100 l/min and a pressure of 300 bars, to more powerful machine for large refilling centres, such as the Mch36 with a flow rate of 600 l/min and a maximum pressure of 425 bars. These compressors are available with single and three-phase electric engines as well as combustion engines powered by gasoline or diesel fuel. Additionally, a series of important accessories is offered, such as filling panels, transfer hoses, oxygen carbon dioxide and helium analysers, 300 to 200 bar reducers with safety valves and other useful accessories. “The use of high-pressure air compressors – says the owner of the company, Claudio Coltri – is very much diversified. They can be used for breathing air, diving or fire departments; to refill systems for air guns such as “paint ball”, a war game with spherical dye-filled gelatin capsules, an anti-stress game; to refill real high pressure weapons, equipped with a 300 bar tank for hunting or target shooting. Last but not least, the industrial use. High-pressure compressors for natural gas and technical gases.
