Unilab SHARK Build 210228 is now available for download! We have published a new SHARK update (build 220228) related to the management of 36 coefficient compressors.

Please be advised that we have made changes to our terms and conditions of sale and annual technical support.

Unilab is proud to announce that our Microchannel Evaporator software is here and available! Our new Microchannel Evaporator module is a uniquesolution in the market for this application. Until now, areal software development for microchannel evaporatorshad never been addressed, mainly due to lack of demandfrom the market and constructional problems of this typeof exchanger.

In previous articles about Pillow Plate exchangers, we’ve looked at the advantages of this innovative technology. In the end, however, a notable advantage of this technology is especially the economic one: because producing a pillow plate exchanger is really cheaper than a Shell&Tube. In fact, except in the case of small S&T heat exchangers, generally the cost of producing a Shell & Tube is significantly higher than the cost of starting a Pillow Plates business, and we see why in this article.

In recent years, there has been a growing interest in pillow plate heat exchangers (PPHEs) because of their versatility to cover a large number of applications in most industries, as well as their high heat transfer efficiency.  In our last article of this series, we will present a comparison, on different aspects, between a PPHE and Shell and Tube, Gasketed Plate, and Spiral Heat Exchangers. We will also discuss in particular the use of PPHE applied to high-temperature flue gas energy recovery.

Last week, we published our very brief introduction about this innovative heat exchanger, explaining the origin of the name pillow, citing some examples of applications, and explaining the fabrication process of the plates.

Pillow-Plates Heat Exchangers (PPHE) are classified as innovative heat exchangers and are used today in a large range of applications such as ice machines, heat pumps, column reboilers, latent heat storage systems, waste heat recovery, jacketed tanks, etc.
