Real-time PID temperature control
Adjustable proportional, integral, and derivative gains with live outlet-temperature response.
PiTemp is a real-time dynamic simulator of a temperature controller for shell-and-tube heat exchangers. Built by PiControl Solutions, PiTemp is process control simulation software that models how a PID temperature loop responds to hot- and cold-side flow disturbances and set-point changes. It gives engineering students and process engineers hands-on practice with a specific, common unit operation: temperature control across a heat exchanger.
Heat-exchanger temperature control is one of the most common loops in a process plant, and it behaves differently from a simple flow or level loop: the process gain and dead time shift with flow rate, fouling, and the counter-current or co-current arrangement of the exchanger. PiTemp exposes that nonlinearity in a safe, offline simulator, so PID tuning and process-response intuition transfer to real equipment.
PiTemp simulates the real-time dynamics of a heat-exchanger temperature-control loop, so students and engineers can tune the PID controller, observe closed-loop response, and build intuition for how flow disturbances move outlet temperature. PiTemp runs on standard Windows hardware, requires no DCS hardware, and ships with configurable process parameters for matching classroom exercises or specific plant equipment. Because it models the same loop behavior engineers later encounter in advanced process control work, the skills transfer directly from simulator to plant.

Setpoint, PV trend, and MV trend in a layout familiar to plant operators.
Runs entirely on a Windows PC — no licence server, no cloud, no internet required.
Engineering colleges and universities use PiTemp to teach heat-transfer fundamentals, process dynamics, and PID tuning in chemical engineering courses focused on process control and unit design. PiTemp replaces static heat-exchanger textbook problems with an interactive simulator, letting students see how process conditions actually influence exchanger performance in real time.
Industrial plants use PiTemp to onboard process engineers onto heat-exchanger temperature loops before they touch a live production loop, and to build tuning intuition on the nonlinear, flow-dependent dynamics that characterize exchanger temperature control across industrial process control systems.

Lets instructors and engineers match the simulator to a specific classroom exercise or real exchanger.
Heat-exchanger temperature control is deceptively hard to teach from a textbook. The process gain and effective time constant change with flow rate, fouling, and the direction of the two streams, so a single steady-state heat-balance problem cannot show a student what closed-loop tuning actually feels like. Temperature loops are also among the most common loops in a process plant, so a gap in this specific skill shows up across nearly every unit that exchanges heat.
A textbook exchanger problem produces one steady-state answer for one set of flows. It never captures how the loop behaves as flow ramps, as fouling builds, or as the controller fights a disturbance in real time.
A student who can derive the heat-transfer equations for an exchanger can still produce oscillating tuning on the loop that controls it, because tuning competence comes from repeated closed-loop practice, not from equation-solving.
Learning to tune a temperature loop on a real production exchanger risks off-spec product, wasted energy, and equipment stress — an expensive way to build a skill that a simulator can teach safely first.
PiTemp removes the structural problem: closed-loop temperature response in real time, on a model that captures the nonlinearity of a real shell-and-tube exchanger, with no production equipment at risk.
PiTemp is one member of a family of single-loop unit-operation simulators from PiControl Solutions, each focused on a specific piece of process equipment.
PiHEx simulates the broader dynamics of a shell-and-tube heat exchanger itself, including overall thermal performance, rather than only its temperature-control loop. PiTemp and PiHEx are often used together: PiHEx for exchanger behavior, PiTemp for the control loop around it.
PiFlow gives the same real-time, hands-on treatment to a flow-control loop, the fast, low-dead-time counterpart to PiTemp's slower thermal dynamics.
PiLevel simulates a vessel level-control loop, an integrating process with dynamics that contrast sharply with PiTemp's self-regulating temperature loop.
Engineers and students train on PiTemp across every sector PiControl serves — each runs heat-exchanger temperature loops with slightly different dynamics, and PiTemp's configurable parameters reproduce the loops their own equipment runs.
PiTemp is deployed in engineering colleges and industrial training departments worldwide, part of PiControl Solutions' family of real-time unit-operation simulators used for process control education and engineer training. Read more in our customer success stories.
