Software
​ECT’s TurboPAC suite of application software solutions are implemented on multiple high performance hardware platforms with trouble-free operation on over a thousand installations worldwide. Our ECT engineers extensively test our systems using closed-loop simulations during product development and customer-witnessed tests to ensure we exceed our customers’ expectations on every project.
SurgePAC
ECT’s SurgePAC Surge Controller uses three specialized algorithms to prevent surge in your compressor. These algorithms are practically designed to be used in the field for better machine protection, quick process recovery during upset conditions, and maximum steady-state energy efficiency.
​
-
Surge Adapter Surge Adapter safely controls the compressor operating point during medium and large disturbances by temporarily widening the surge control margin and then reducing the margin back to its original position during steady-state conditions providing extra protection when you need it and minimizing recycle when you don’t.
-
-
Surge Preventer During very large process upsets, Surge Preventer backs up Surge Adapter by opening the surge control valve using a fast closed loop response using process feedback to prevent the operating point from hitting the surge limit line without over-opening the valve. This patented response is proven more effective than outdated open loop response used in legacy systems.
-
​
-
Surge Stopper In the unlikely event your compressor reaches the surge limit line (usually due to a problem with the surge control valve), Surge Stopper will detect surge and take corrective action by moving the Surge Control Line and Surge Preventer Lines out to the right to prevent subsequent surge cycles. If surging continues, ECT’s Surge Detector will count the cycles within a configurable timeframe and can initiate a machine trip to protect the machine.
PerformancePAC
ECT’s PerformancePAC Process Controller controls your plant’s main process variable while limiting up to five additional process, performance, or mechanical constraints. PerformancePAC controls with the following control elements:
​
-
Inlet throttling valve
-
Inlet guide vanes
-
Turbine speed control
-
Variable speed electric drives
​

NetPAC
ECT’s NetPAC Network Control System works with companion LoadPAC Loadsharing Controllers to precisely control your compressor suction and discharge headers using supervisory and distribution algorithms to distribute the load among operating compressors in parallel or series networks.
LoadPAC
ECT’s LoadPAC Load sharing Controllers work with the NetPAC Controller using the companion SurgePAC Surge Parameter Distance calculation for optimum load distribution of the compressors in the network.
Interaction Control
Control loop interaction can be a significant problem when controlling turbocompressors. The interaction between process and surge controllers can lead to control instability resulting in compressor surging and operators detuning the system or switching the system to manual leaving the machine unprotected with the operators continually needing to change outputs to try to maintain process control.
SpeedPAC
ECT’s SpeedPAC Speed Controller provides the following functionality for steam turbine control:
​
-
Startup/Shutdown Sequencing
-
Critical Speed Avoidance
-
Extraction Control
ECT provides industry-available separate overspeed trip systems in addition to the SpeedPAC Speed Controller for complete steam turbine control and protection. ECT also works with partners for upgrades of old mechanical governors using the latest designs for mechanical retrofit kits for speed measurement and actuation systems.
ExpanderPAC
​ECT’s ExpanderPAC is a Dual Performance Controller Application designed to seamlessly control the expander inlet nozzles and bypass valve eliminating fighting between the valves using Interaction Control and smooth transitions when moving between the nozzles and bypass valves.
LogicPAC
​ECT’s LogicPAC is an application designed to standardize compressor logic with embedded configurable components. This design allows for easier troubleshooting in the field - especially lube oil and seal gas system parameters.
AirPAC
​ECT’s AirPAC is used for plant air compressor control including performance control, load sharing of plant air networks, surge control and logic/sequencing.
QuenchPAC
ECT’s QuenchPAC Quench Controller works with its companion SurgePAC Surge Controller through Interaction Control to minimize the interaction between hot gas recycle and liquid quench typically used on multi-section refrigeration compressors with sidestreams.
StationRecyclePAC
​ECT’s StationRecyclePAC controls the overall station recycle valve frequently used in large compressor networks with multi-section machines. StationRecyclePAC works with the individual SurgePAC Surge Controllers to operate the station valve so that individual recycle valves remain closed during steady state reduced throughput for stable control of process setpoints.
ScrewPAC
​ECT’s ScrewPAC is designed for critical process screw compressors often in compressor networks including process reciprocating compressors and centrifugal compressors.
RecipPAC
​ECT’s RecipPAC is designed for critical process reciprocating compressors often in compressor networks including process screw compressors and centrifugal compressors.
