Pignat Electrical Engineering Training Systems are high quality, innovative units that will provide your students with top of the line educational experience. Here are a few  example trainers to illustrate the level of quality and detail you can expect from every Pignat trainer.

Continuous Distillation

Distillation is a method that involves the transfer of heat and materials to achieve the separation of one or more products with varying levels of volatility. This separation is accomplished through a series of vaporizations and condensations.

The underlying principle is that vapor generated from a mixture is in equilibrium with the liquid phase of the mixture and typically has a higher concentration of the most volatile compound. The process takes place within a column, which can be either packed or consist of plates, strategically designed to optimize contact and material exchange between the ascending vapor and descending liquid within the column.

These separations can be conducted through either continuous or discontinuous (batch) processes.

Water/Waste Water Treatment – Automated Biological Treatment

In this approach, an aerated reactor serves as the habitat for thriving populations of microorganisms responsible for breaking down dissolved organic pollutants, such as COD (Chemical Oxygen Demand) and BOD5 (Biochemical Oxygen Demand).

This reactor is intricately linked to a clarifier, facilitating the physical separation of the treated effluent and biomass through settling processes. Additionally, the treatment of nitrogen compounds, specifically nitrates, can be achieved by either cultivating an anoxic working range within the aerated basin (characterized by a lack of ventilation) or by establishing a separate, unventilated anoxic basin upstream.

Instrumentation and Process Control – 4 Variable Process Control Trainer

This independent unit consists of two tanks and two pumps operating within a closed circuit, providing a platform for the exploration and configuration of various control loops, either individually or in cascade.

Key features include:

  • Control of water flow rate through valve adjustment
  • Water level regulation via valve manipulation
  • Discharge pressure management through pump variator control
  • Water level adjustment through pump variator control
  • Bath temperature regulation utilizing an electrical heater
  • Control of exchanger outlet temperature via valve manipulation
  • Flow/level cascade control through valve adjustment
  • Discharge pressure/level cascade control by manipulating the variator

Simultaneous operation of two control loops is possible, facilitated by safety plugs connecting sensors, controllers, and actuators. The components employed are industrial-grade, allowing for in-depth technological study with the aid of technical documents provided in the accompanying technical file.

A tactile screen displays measurements, control parameter settings, the auto/manual operating mode, and records data onto a USB stick.
