UNILAB COILS is the most accurate software for the design and rating of finned pack / smooth tube heat exchangers. And EASY is its little brother: an indipendent software which allows you to generate a 3D view of the Coil, metal sheet drawings for the production and to create its circuiting automatically! Discover EASY!


UNILAB COILS allows you to calculate using any geometry and tube size (such as 7mm, 3/8 in., 1/2 in., 5/8 in., etc.) and comes with a list of more than 100 sample geometries. An easy to use wizard also help you create new custom geometries in a few clicks. 


UNILAB COILS comes with more than 1000 fluids and also offers the option of using New Refrigerants such as R32, R1234yf, R1234ze, R445A, R446A, R447A, R448A, R449A and many more, constantly updated from the latest version of the Refprop library. 

UNILAB COILS is the best & most accurate software for the calculation of Coils Heat Exchangers and can be used in air conditioning, fancoils, industrial chillers and air handling units. It is an advanced tool for the calculation of both finned pack and smooth tube heat exchangers, and includes specific features for the HVAC market.
Compared to laboratory tests, UNILAB COILS calculation results show a very high level of accuracy in both capacity and pressure drops, allowing you to certify your heat exchangers, fancoils or air handling units with Eurovent and AHRI at the first attempt.
UNILAB COILS is the result of over 30 years of experience in the HVAC market, validated by experimental data and consolidated customer satisfaction.

Estimate performance of new geometries

In UNILAB COILS there are no limitations to calculation using new geometries, making it possible to analyse their performance before mass production begins.

Coils for Automotive Radiators

UNILAB COILS is also capable of calculating the performances of radiators with rectangular tubes, in both design and rating, making it possible to design or optimise radiators with linear fins to cool endothermic engines, with either aligned or staggered tubes.


Several of our customers have achieved EUROVENT or AHRI certification by submitting UNILAB COILS software to test their units. Compared to the laboratory test, COILS results on capacity and pressure drops are within the narrowest range and our COILS customers have been successful in achieving certification at the first attempt!
