Denaline is widely recognised as a global leader in its sector, selling innovative products for over 40 years, created out of a natural-born desire for continuous improvement.


    Our products are entirely manufactured at our Pordenone facility and have conquered the main international markets, with an export quota reaching 80% of total turnover. That’s thanks to their controlled, certified quality, performance and competitiveness coupled with our professional, customised service. The Denaline strategies are designed to ensure long-term stability.


    Investing in training our workforce and collaborators and in innovation has allowed us to develop a fully integrated, technologically advanced production cycle.
    As a company we encourage talent, free thinking and responsible behaviour and we nurture our collaborators, who have ample freedom to make decisions according to agreed guidelines..


    Our company has received a non-repayable grant for the following project: “Computerisation of high pressure receivers” under Competition POR FESR 2014-2020, Activity 2.3.a.1 bis “Grants to help SMEs make technological investments.

    The aim of this project is to extend the capacities of an existing production plant by reorganising the production processes of the lines producing high-pressure receivers and involved in galvanic treatments, to the purpose of increasing production efficiency and product quality.
    The project’s goal is to instal new equipment and cutting-edge software that is very flexible to use. The new investments are developed with electronic process controls and come into action in delicate production phases and during the surface treatment of semi-finished products.
    The expected results consist in the rationalisation of material logistics and flows, the reduction of manual operations for tooling and reworking of pieces, and the reduction of product throughput times.

    Expense permitted: 152,550.00 Euro
    Grant awarded: 55,249.15 Euro

    Our company has received a non-repayable grant for the following project: “New, flexible, efficient production processes backed by «Industry 4.0» technologies, under Competition POR FESR 1.2.a.1 “Innovation – food and drink, strategic production chains, maritime technologies and smart health” (2017 Competition).
    This project regards the introduction of a new process for the company that wants to acquire the technological and computer science know-how necessary to automate and control in real time – even remotely - one of the main production processes of the company, i.e. the square valve body, one of the cruxes of the factory’s flow.
    Implementation of this project will achieve the following goals:
    - a minimum 2% increase in turnover on current volumes;
    - acquisition of new sectors of the industrial and commercial refrigeration market;
    - acquisition of new customers.

    Expense permitted: € 259,898.73
    Grant awarded: € 103,959.49

    Our company has received a non-repayable grant to conduct a research project under COMPETITION POR FESR 2014-2020, Activity 1.2.a “Incentives to companies for collaboration in industrial research and experimental development – Food and Drink, Strategic production chains”.

    By means of this project, Denaline intends to study and define new organisational models able to support and develop new operational strategies, guaranteeing management of the new technological solutions identi- fied, based on the use of intelligent equipment.

    The following end results are expected from the project:
    - start of a new organisational model
    - set-up of some production processes
    - implementation of ongoing control
    - implementation of automatic adjustments to accura- tely check dimensions
    - intergration and interfacing of various operational environments
    - remoting software.


    Denaline has been operating for 40 years in Pordenone, North Eastern Italy, a city with a thriving entrepreneurial scene which has over the years kept pace with innovation and technology, successfully developing numerous manufacturing companies and thus generating growth for the local area.

    Set up in 1977 by an engineer, Mauro Avanzini, founder and current CEO of the company, Denaline started out selling products for air conditioning and industrial refrigeration such as tube condensers, liquid receivers and bronze connections, mostly within the Italian territory.

    Manufacturing of the first valves and rotalock connections started in 1984, in a rented 300 sq.m. plant just outside Pordenone.
    In 1990 in line with a rising demand for industrial refrigeration products and components from major global firms, the company decision makers opted for setting up the first company-owned facility in Pordenone’s new industrial zone, on a 1,400 sq.m. site including manufacturing space, offices and services. In 1996 the manufacturing facility was expanded by a further 2,100 sq.m.

    Simultaneously, the management, organisational, technical, sales, administration, research, automated warehousing and logistics departments were all upgraded and made more efficient over the years.
    Quality, service, competitiveness and responsible, well-considered corporate decisions led overseas turnover to reach 80% of the overall figure.
    Our clients are guaranteed controlled, tested and certified products, exclusive patented technical and industrial solutions, and a registered brand that's protected at European and world level via direct correspondents.

    The current site, which doubled in size between 2006 and 2008, sits on 8,500 sq.m., including 900 sq.m. of offices and services. Manufacturing capacity: 250,000 receivers and over a million valves per annum.

    Our manufacturing processes and systems have been a continuing focus for the company, with the goal of continuing improvement of production cycles, energy saving, environmental responsibility and scrupulous attention to mental and physical working conditions for our workforce .

    A fine example of Made in Italy drive and ability shaped by an intense passion for working hard that has always been shared by the Denaline staff - from the current company president Mr Mauro Avanzini to senior management and across the entire workforce.


    A leader is not a leader unless he’s not only thinking about technological innovation and product performance, but also about our shared heritage: the environment.

    Denaline has always focussed on green issues which means
    - developing a new category of products using natural, environmentally compatible refrigerants,
    - systems in which the components are fitted are low environmental impact,
    - long product life cycle, another important sustainability factor.
    Our products, industrial processes, from design to disposal, and work environment are all particularly environmentally sustainable, environmentally clean and economically efficient, and we ensure energy saving in offices and services


    Further to an idea of the Municipality of Pordenone, Denaline has joined the “Solidarity for Transport Services on the Municipal Territory” project by contri- buting to purchase a new vehicle to transport patients requiring treatment in specialist centres.
    This free transport project has been developed by a specialised company that makes specific, accessorised vehicles available to Social Services who use them to transport people with reduced mobility.


Research and development is the foundation of Denaline quality
