Gas Flex® is an easy to use PC based Windows 9x, Windows NT and Windows 2000 program that uses Benedict-Webb-Rubin (BWR) equations of state for accurate compressor performance analysis.

Program features include:
State Point Calculation - Input a pressure and temperature, Gas Flex® calculates enthalpy, entropy, saturation point, specific volume, sonic velocity, Cp , K value, and dynamic viscosity. Saturation Point Calculation - Input a pressure or temperature,

	Gas Flex® calculates the corresponding saturation temperature or pressure.
	Compressor Estimation - Input flow rate, inlet conditions, & discharge pressure, Gas Flex® calculates inlet and discharge volume flow, polytropic head, discharge temperature, and gas power for multi-section compressors including sideloads.
	Compressor Test Data - Input field or factory test data, Gas Flex® calculates overall compressor performance including flow rates, power, and efficiency. Note - this option can also be used to verify compressor performance in new proposals.
	Detailed Printout - includes all relevant pressures, temperatures, enthalpies, specific volume, performance calculations and field test results.
	Control of Units - for any input or output item. All of the commonly used units (e. g. psia, Bar a, kg/cm2 a, etc.) are available.
	State Point Calculation
	Pull Down Windows - Pull Down Windows are used for ease of program operation.

Monitor your compressor performance "Live" and continuously using Gas Flex RL. You can "see" where the compressor is operating and monitor transients as well as long term trends. Confirm Vendor guarantees and know the effectiveness of overhauls. Save time and money over expensive field performance analysis procedures yet still have PTC-10 quality results in hand.

Features Include:

	Dynamic Data Transfer
	Data Trend Plot
	Speed Compensated Curve
	Coefficient Curve

Air Flex is an easy to use PC based Windows and Windows 95 program that accurately calculates air compressor performance including flow rates based on orifice or annubar data, and state point data for various conditions.

Program features include:

	Compressor Estimation - Input flow rate, inlet conditions, & discharge pressure, Air Flex calculates inlet and discharge volume flow, adiabatic head, discharge temperature, and gas power.
	Compressor Test Data - Input field or factory test data, Air Flex calculates overall compressor performance including flow rates, power, and efficiency. Note - this option can also be used to verify compressor performance in new proposals.
	State Point Calculation - Input a pressure and temperature, Air Flex calculates, specific volume, sonic velocity, Cp , K value, and dynamic viscosity. A detailed summary printout is available which includes pressure, temperature, specific volume, sonic velocity, Cp , K value, and dynamic viscosity for: state points, compressor performance calculations and field test results. The units of measurement may be varied for any item. All of the commonly used units (e. g. psia, Bar a, kg/cm2 a, etc.) are available.
	Pull down windows - Pull down windows are used for ease of program operation.

Steam Flex is a program based on Keenan & Keyes steam tables. Various steam properties can be calculated by the user.

Program features include:

	State Points - Steam state points can be calculated given a pressure and any of the following: temperature, entropy, enthalpy, and moisture.
	Steam Rates - Theoretical steam rates can be calculated given inlet and exhaust pressures, plus inlet temperature, inlet enthalpy, inlet entropy, or inlet moisture.
	Estimations - "Straight through" steam turbines can be estimated given power or inlet steam flow, speed, efficiency, inlet and exhaust pressures, plus inlet temperature, inlet enthalpy, inlet entropy, or inlet moisture. A feature allows the estimation of blade heights when disk base diameters are given.
	Extractions - Extraction or induction steam turbines can be estimated similar to the straight through type.
	Field Test - Turbine efficiency can be evaluated based on Field operating data. Detailed print outs are available with each program function. Full control of the input and output units is available. All normally used English system and metric system units are user selectable.

Heat Flex® is a program that calculates steam turbine regenerative cycle heat balances. This type of program has been used for several years in numerous applications. The Heat Flex® program will calculate the entire cycle with great accuracy.

Program features include:

	Up to four heat mediums can be used in the cycle. Open de-aerating, normal shell and tube, condensate cooled shell and tube, plus pumped condensate shell and tube heaters are available.
	Inlet steam flow or generator power are the primary inputs. Fixed pressure and floating pressure extraction steam are options.
	The final feed water temperature may be fixed or selected by the program.
	Off design cases may be run with fixed or floating feed water temperatures.
	Heater terminal temperatures and pressure drops are user selectable.
	The boiler feed water pump is estimated.
	A detailed printout is available which includes all relevant pressures, temperatures, and enthalpies
	Full control of the input and output units is available. All normally used English system and Metric system units are user selectable. Steam conditions are based on Keenan & Keyes steam tables.
