Your solution provider for Steam systems
• Steam Production: poor energy efficiency
• Steam Distribution: water hammers, leaks, insulations
• Heat Exchange: water hammers, corrosion, unstable temperature, joint leaks, poor
energy efficiency, insulation problems
• Liquid, Air and Steam trapping: losses of live steam, flooded installation, frequent
maintenance
• Condensate recovery: abnormal pump maintenance, low condensate recovery rate,
water hammers, loss of flash steam

SteamStar is the first and only Web-based application (www.SteamStar.com) to record,
control and manage your steam trap system data. It gives you several important
advantages:
 Accurately shows losses in steam, fuel, money and CO2 emissions, based on formulas approved
by the United Nations Technical Committee
 Database of more than 6,000 Cv factors allows to calculate real steam losses for any trap model
from any manufacturer
 Lets you easily compare and view data from local, regional or global locations
 Provides ROI prioritization through failed steam trap work order reports
 Survey data from Microsoft Excel, third-party software or handheld testing devices can easily be
uploaded
 Eliminates the need for expensive software maintenance, training, upgrades and licensing fees
 Numerous reporting capabilities include benchmarking and trend analysis
 Reports in multiple languages, measurements and currency values

Optimizations of steam systems
 During trap survey, the Armstrong specialized technician detects other
anomalies of the steam system (outside of trap stations)
 A monthly visit of Armstrong Specialist Engineer to confirm (or not) the
anomalies
 Summary report is presented during Site Unit’s debriefing meeting
 Contract option foresee the possibility to study in details the Steam
System’s anomalies
