PROTO-SPRINKLER^TM performs steady–state analyses of fire suppression sprinkler systems calculates the required riser pressure to meet minimum nozzle demands or the actual flowrates with known pump curves or pressures. Using a complex set of simultaneous equations represented by a matrix the program calculates corrections to the initial pressure estimates using a combination of a successive overrelaxation method and the Newton-Raphson method. PROTO-SPRINKLER also follows the standard methodology and approach for calculations as specified in NFPA 13, Standard for the Installation of Sprinkler Systems, and NFPA 15, Standard for Water Spray Fixed Systems for Fire Protection.

PROTO-HX^TM calculates steady-state temperatures and heat transfer through shell and tube heat exchangers, finned tube air coolers, and chillers. The user defines the heat exchanger physical parameters as well as design and actual performance parameters in an interactive, easy-to-learn, easy-to-use environment with the flexibility to model simple or complex heat exchanger configurations. After the model is established, field test data can be evaluated using PROTO-HX to predict current heat exchanger fouling and heat transfer capability extrapolated to design conditions.
