Unilab was established

in the eighties, in January 1987 to be precise. However, our passion for heat transfer has much earlier origins; the year 1979 when Ing. Fucile first developed pilot calculation software for finned packed heat exchangers.

Since 1987, Unilab has been

putting customers’ needs at the centre of our mission. Since our earliest days, we have experienced constant growth in terms of Product Catalogue and Expertise. Initially, we focused mainly on the domestic market.

We have continued to

offer advanced software solutions for the design and rating of the single component (originally coil, shell, plate, coaxial, tube in tube and electrical heat exchangers) and the estimation of the whole unit (i.e. air handling units).

  • From the mid-nineties to the early 2000s, Unilab rose through the ranks, by consolidating our international customer portfolio, visiting the most important trade exhibitions, and developing customized software solutions.

We have gradually

developed a customized electronic catalogue for the selection of the whole unit (e.g. liquid chillers, industrial heat pumps, air conditioners, fan-coil units, and ventilated units).

  • In 2008, Unilab exhibited at two major International Trade Fairs for the first time: MCE and CHILLVENTA.

Little by little,

we have increased our international presence, which has led to interesting and successful business ventures in locations such as Russia, India, Turkey, Germany, China, Japan, and Spain, through our participation in events such as Chillventa Rossjia, Acrex India, ISK Sodex, ISH Frankfurth, China Refrigeration, HVAC Japan, MCE and Climatizacion.

We have met many key players in the sector, either when they visited our booth at trade fairs, or while visiting such events ourselves, enabling us to get to know them and discover new business opportunities.

We have extended our boundaries by enhancing our top-selling software (Electric Suite, Smart Air, Coils) to embrace the latest technologies, in order to create new cutting-edge software solutions.

This innovation was the key to the development of new software (i.e. for microchannel condensers, indirect electrical heaters, dehumidifier heat pipes, and for batch processing equipment, such as pillow plate heat exchangers).

  • In 2015, Unilab thought outside the box, by attending ACHEMA – an International Trade Fair which focuses on the Chemical Engineering and Processing Industries. It proved to be a successful strategy, helping us forge links with many potential clients.

In Unilab,

In Unilab, you will find a well-qualified business partner who understands your requirements and objectives. We share your goals and speak the universal “heat transfer” language.

Thanks to our solid experience, we can offer you advanced software solutions for the design and rating of the single component (any typology of heat exchangers) or the simulation of the whole unit (i.e. liquid chillers, ventilated units, or air handling units).

Our reliable and accurate

Our reliable and accurate software makes the designer’s work much easier. Our technical and scientific experience are especially valued by our customers. We analyse and decipher their needs, and shape our findings to create tangible software solutions. We are the ideal partner when it comes to the development of customized software solutions and engineering design services.

Despite being a relatively small company (a team of 13), Unilab is capable of overcoming new challenges in order to help our clients become leaders in the new ‘niche’ markets.

We have become the trusted partner of many leading domestic and overseas companies among our 500 clients in more than 70 nations. Work with us and become part of the Unilab success story.
