Blygold® is a polyurethane coating containing aluminium pigments. It gives long-lasting protection without reducing efficiency or causing loss of pressure, and can be applied during manufacture or on site. A thin coating of Blygold® ensures good heat exchange and a high level of chemical protection.
When applied by certified operators working to Blygold® specifications, PoluAl XT is extremely effective at preventing damage to air conditioning systems and curbing excessive energy consumption. Corrosion resistance (ASTM B117): 4,000 hours.
This is an anticorrosive coating containing thermosetting phenolic resins for special applications requiring complete covering of the heat exchanger. It provides high corrosion resistance in marine and saline environments and is effective against a wide variety of corrosive fumes, chemicals and condensates.
Heresite® coating is widely used in the HVAC-R sector, extending the life span of heat exchangers, coils and other devices that treat air and smoke containing particles of light metals. Corrosion resistance (ASTM B117): 6,000 hours.
Thermoguard® has developed Finguard Silver SB for protecting heat exchangers. This polyurethane coating with aluminium pigments protects against saline environments, chemical agents (resistance table available) and UV radiation. Finguard Silver SB is applied by spraying performed by certified operators both in the factory and on site. Corrosion resistance (ASTM B117): 3,000 hours. Colour: silver.
This is an ideal anti-corrosion treatment, applied by immersive cathodic electrodeposition. It can be customised with specific chemical formulae to match the technical characteristics of each heat exchanger, and is effective in marine and industrial environments. The consistency and uniformity of Electrofin® E-Coat provides protection against a wide range of corrosive chemical fumes. Guaranteed for 5 years, corrosion resistance (ASTM B117): 6,000 hours.
Tinning is an electrolytic immersion treatment used to protect metals such as copper, iron, aluminium and their alloys. Compact tin coatings are widely used for protection against atmospheric agents, water, solutions and many other substances, including foodstuffs. In addition to high corrosion resistance, tinning gives visual appeal and very high electrical conductivity.
This electrodeposition process is recommended for creating a primer coat on the surfaces of elements made of iron, steel and other alloys. It offers excellent resistance to atmospheric corrosion and other forms of attack, and improves the adhesion of powder coatings. This type of coating has poor resistance to UV exposure, and is therefore not suitable for use in direct sunlight.
High quality raw materials, advanced machinery, quality control at every stage.
The frame is made of galvanised sheet steel, 304/316 stainless steel, copper, aluminium, brass or descaled steel plate, and is made in such a way that the fins and bends are well protected.
The tube holes in the tube plate are fitted with collars made of the same material as the fins, which allow the tubes to move freely in order to prevent thermal expansion causing cuts and breakages.
The finned core is made from materials that can be selected in our calculation program. The fins are fitted with a collar of variable height enabling fin spacing to be controlled. Fin surfaces are corrugated to increase stability and to generate air turbulence for a higher heat exchange coefficient.
This type of surface also prevents dust accumulating inside the finned core and helps to disperse condensation.
We use tubes of various diameters and internal finishes to construct the most appropriate heat exchangers for user requirements.
Tin-plated tubes have anticorrosive properties while grooved tubes provide much better energy exchange than those with smooth inner surfaces.
A hairpin-bender is used to make tubes for exchangers with a finned length of up to 4,000 mm, and a pipe straightener for greater lengths. Eurotec takes great care during mechanical expansion of the tubes, which must be in perfect contact with the fins for optimal heat exchange.
The headers of the exchangers, produced in-house, are made of copper in a work centre equipped with a latest generation tube-end closing machine.
The ends of the headers are shaped appropriately for the way in which the heat exchanger will be used.
All our heat exchangers undergo rigorous sealing tests before delivery. Eurotec tests all its products in a tank at pressures ranging from 20 to 55 bar.
All freon exchangers are delivered hermetically sealed and charged with nitrogen.
Product quality and customer service that give maximum satisfaction
The German certification body TUV confirms that the ISO standard has been applied in a manner that creates maximum customer satisfaction with regard to delivery times, levels of service and compliance with contract terms.
The internal Quality Department supervises every stage of the process, from the heat exchanger design to the selection of suppliers and raw materials, from careful monitoring of construction to the rigorous 21-stage final testing, the results of which are reported on the QC label of every product.
The company conducts an annual self-assessment by means of an internal audit of every business area and a system of digital tracking and control that performs real-time health checks of the production unit.
Eurotec SRL has a modern and functional 2,500 sq.m. plant in the industrial area of Stezzano, 3 km from Bergamo.
It has a young and dynamic staff, and over 30 years experience in its sector.
Our heat exchangers are manufactured on cutting-edge machinery to help us meet our goal of offering products with superior quality-to-price ratios.
Our values are people, product quality and customer care. Our mission is to give maximum customer satisfaction.
Regular staff training, continuous monitoring of production and success in obtaining relevant certification are evidence of our determination to excel. The technical office is always at the service of customers to respond to any need or to assess the viability of customised products. We can also provide clients with software for the thermodynamic calculation of our exchangers.
