Why Choose UniSuite WEB?

Most companies don’t need—or can’t justify—the high cost of traditional heat exchanger software. Especially when calculations are only needed a few times per year.

What if you could run accurate simulations, anytime you want, from anywhere, without consultants or long-term contracts?

That’s exactly why we created UniSuite WEB: Unilab’s online, browser-accessible Design, Rating and Selection as a Service platform.

Flexible Time & Payment Model

  • Pay-per-use: No mandatory annual contracts. No ties.

  • Scalable packages: 2 days, 7 days, 1 month, 6 months, 1 year

  • No long-term license lock-ins: Ideal for occasional users

 Fully Web-Based

  • No VM installation or deployment on the cloud, just access and calculate.
  • Works on any system — no installations, no compatibility issues

  • Use from home, office, or site — just an internet connection is enough

Cost-Effective

  • Avoid large upfront software investments. Ideal for infrequent use or when outsourcing to consultants is too expensive.
  • Choose the right plan for your workload, with unmatched flexibility.
  • No more five-figure yearly or 3 year licenses.

Simple & Modern Interface

  • Clean UI/UX — no training required, Get started immediately.

  • Built-in fluid properties archive and tubes archives

  • Save, download, share projects with your colleagues.

Always Up-to-Date

  • Cloud-based updates — no downloads or patches required

  • You always work with the latest version

Focused Support

  • Report issues directly within the platform

  • Priority support packages available

Maximum Safety and Privacy

  • Your data stays yours, managed under GDPR compliance.
  • Unilab accesses your profile only if you request support.
  • All data stay private, and shared, even with your colleagues, only if you choose.

Transparent & Neutral

  • Many tools on the market aren’t truly general-purpose — they’re engineered marketing tools, not neutral technical solutions.

  • A software tightly tied to a brand may hide technical, commercial, or strategic limits.

  • UniSuite is independent and neutral, designed specifically for engineers and designers.

Start with SHELL & TUBE

The first tool in the UniSuite WEB ecosystem is our powerful SHELL & TUBE module: a complete Design, Rating and Selection solution for Shell & Tube Heat Exchangers.

Features

SHELL & TUBE

YOUR FLUID DATABASE

All UniSuite software uses NIST’s REFPROP library for thermodynamic properties of over 300 fluids, 12 mixtures, and various OILS and refrigerants, plus our own extension of 200+ liquid foods and beverages and NON-NEWTONIAN FLUIDS. And you can EXPAND IT WITH YOUR FLUIDS. Our solutions serve industries like process, chemical, pharmaceutical, energy, food & beverage, automotive, and are a trusted asset in HVAC&R since over 35 years.

YOUR TUBES DATABASE

Along with a wide, extendable tube database, UNISUITE now allows geometrical insertion of one-start corrugated tubes in Shell & Tube and Tube-in-Tube applications—with no corrective factors needed. This exclusive feature, the result of months of research, adds to our archive of corrugated and low-finned tubes for precise, efficient steam and fluid-fluid simulations. 

CASCADE

Our advanced shell software now supports precise design and rating of cascade evaporator-condensers. The new Cascade Mode lets one fluid evaporate while another condenses in the same heat exchanger—like ammonia evaporating and CO₂ condensing—boosting thermal efficiency. Both configurations are supported: evaporation on the shell side or on the tube side.

VAPORIZER

SHELL now allows to calculate two-phase/two-phase vaporizers, where water vapour at low pressure, low temperature on one side is vaporized with water vapour at higher pressure and temperature on the other. Another case where this application is used is also water vapour on one side an methane passing from liquid to gas on the other. 

FAST LEARNING CURVE

Immediate use of fluid archive and mixtures: no need to know which calculation mode to use before calculating. Simply choose the fluid, and let Shell do the rest. Fast learning curve: no need for high level training or high skills to use it. And if needed, training can be tailor made to face your case studies (contact sales@unilab.eu)
