Surge protection that throttles deeper before it bypasses.
E Care's controllers define the true surge point by Deviation, not by a fixed guess — so your compressor runs further into its efficient range before the bypass valve ever opens.
Deviation defines the real surge point — at zero.
The industry-standard method calculates the surge point from Polytropic Head, which is affected by stage inlet temperature, inlet pressure, and discharge pressure — meaning the calculated point can drift from where the compressor actually surges.
E Care's Surge Deviation control instead defines the surge point directly, as "0" Deviation, and opens the bypass valve only as that threshold is approached. Because the reference point is real rather than calculated, the compressor can safely throttle deeper before bypass begins — reducing energy consumption every time the system is throttled.
1Polytropic Head Control
Measures the work performed by the compressor in foot-pounds per pound of gas (ft-lb/lb). It's the standard method — but sensitive to shifting inlet and discharge conditions.
2Surge Deviation Control
Defines the actual surge point as zero deviation, letting the compressor throttle deeper before the bypass valve opens — for meaningfully lower energy use under part load.

TSI Remote Monitor extends that same system into a browser — live thresholds, alarm history, and email alerts, so you can see machine health without walking the floor.
Explore Remote MonitoringThree coordinated PID loops
The ECC / 10RCC platform runs three Proportional-Integral-Derivative loops in parallel to keep the machine both safe and efficient:
- Bypass valve control — modulates the blow-off valve based on Surge Deviation to prevent surge without wasting more air than necessary.
- Inlet valve pressure control — regulates inlet guide vanes/valves to hold discharge or system pressure at setpoint.
- Motor current / Full Load Amp protection — continuously monitors motor current to protect the machine from overload conditions.
