Types of MDI Controllers

The MDI controller is a key element in the machine for making PET bottles. It takes care of blowing the preform to its final capacity and has different kinds of controllers that help with this by measuring pressure, temperature, and air flow.

According to how the different parts work together, there are two main categories of MDI controllers:

  • Type A: This is when all the blowing equipment and air tanks are together in one place on the machine. This makes everything simpler and easier to manage. The operator can see and control all parts related to pressurized air systems from a single station.
  • Type B: When the blowing equipment is separated from the rest of the machine, this type is used. The operators can change different air pressure and temperature controllers spread across multiple stations in this kind.

The choice really depends on the kind of machine and operator preference. While type A controllers combine everything in one location, which makes it possible for quickly adjusting and monitoring all parameters from a single point, type B controllers offer better flexibility by separating blowing apparatus from other machine components.

Apart from these two types, there are more types of MDI controllers available:

Different processes will likely require distinct types of material and instruments.

  • MDI 1: It can precisely control the MDI production process to uphold required quality criteria.
  • MDI 2: This kind has a dual function, and while controlling the MDI production process, it does the first step of the reaction needed to create the isocyanate.
  • MDI 3: With its cutting-edge features, this model enhances efficiency and productivity in the workplace.
  • MDI 4: It has a variety of functionalities to optimize various stages of the MDI production process.
  • MDI 5: This type can be used in an explosive environment, helping safe operation under dangerous conditions.
  • MDI 6: It is known for its simple installation requirements, making it easier to integrate into existing systems.
  • MDI 7: This kind has to do with temperature control in the production of medical devices, ensuring that the prepolymer and isocyanate temperature stays within required limits.

Functions and Features of MDI Controllers

Every MDI controller has its functions and features. They include;

  • Multiple Signal Outputs

    MDI controllers provide various output signals, such as 4-20 mA analog outputs, Modbus RTU, and digital outputs. These signals enable system operators to monitor and control their processes actively. With these signals, process parameters can be continuously monitored, and their values can be transmitted to the control system. These controllers receive values from different sensors and transmit them to other systems for further analysis and decision-making.

  • Proven Technologies

    MDI controller makes use of proven technology. Its efficiency and reliability have been recognized by different industries. The controller features microprocessor technology and generates outputs for measuring devices. It also has an electronic circuit with an LCD for potential future upgrades. Due to its proven reliable technology, MDI controller minimizes risks found in unproven technologies.

  • Output Signal Standardization

    The MDI coordination system improves safety and saves on costs by standardizing output signals. The system harmonizes output signals according to specifications so that personnel can operate and maintain the signals efficiently and systematically. Standardization minimizes errors, enhances safety and facilitates troubleshooting and maintenance.

  • Measurement Points

    MDI controllers have numerous measurement points, which are the number of locations in a system where measurements must be taken. Each measurement point has a dedicated measuring instrument to provide accurate data for the process controls. The number of measurement points varies depending on the application, complexity and system requirements. The greater the number of measurement points, the more accurate the assessment of the operating conditions will be. This ensures effective monitoring and control of the system. Each controller provides data for up to 12 measurement points. This improves the assessment of operating conditions.

  • Electronic Pressure Switch

    The electronic pressure switch is a vital component of the MDI control system. It measures and monitors pressure within a system and provides accurate and reliable pressure measurement. The electronic pressure switch has features like digital output that provide information on system pressure. It also has an adjustable pressure set point for controlling and monitoring system pressure.

Uses of MDI Controller

Main purposes of an MDI controller are to manage an engine's mechanically injected diesel system, provide controllers for the operator, and continuously monitor, display, and record information about the system's temperature, fuel, and pressure. The MDI controller is for mobile machinery, and the controller helps with starting, stopping, and speed regulating the diesel engine. When using an MDI controller, it is important to follow the manufacturer's guidelines to avoid any potential hazards. The controller can extract a lot of information from the engine to improve efficiency and performance.

The MDI controller is used to integrate with CANbus sensors. It uses the data from the diesel engines to provide feedback to the driver/operator. With this technology, operators can learn more about the engine's performance based on what is displayed on the main screen. Since the controller can control engine speed, it plays a crucial role in modulating how much power the engine makes. In turn, this power affects the machine's drivetrain and wheels/track movement.

  • Marine Applications: The MDI controller allows marine vessel engine managers to control and monitor multiple diesel engine parameters and instantly respond to changes in operating conditions. It helps with starting/stopping the engine and controlling engine speed/setting mode. Therefore, the controller contributes to the overall safety and efficient operation of marine diesel engines.
  • Generator Sets: If a generator set's main engine fails or has issues, the MDI controller can quickly and effectively shut down or alter operating conditions. The controller continuously tracks and monitors different functions and parameters of the engine, which are critical for normal and safe operation. Moreover, the controller helps the generator achieve optimal overall performance by controlling its speed.
  • Industrial Machinery: An MDI controller can control mobile machinery powered by diesel engines in various fields, including mining, construction, or material handling. In these situations, the controller helps achieve efficient and reliable operation of the diesel engine, contributing to the overall productivity of the mobile machinery and minimizing unplanned downtime.

Q&A

Q1: Can MDI controllers be used with any type of diesel engine?

A1: Not really. MDI controllers are specifically designed to work with engines that require diesel exhaust fluid (DEF) systems for emissions control. Therefore, they are most applicable to modern diesel engines compliant with stricter emission standards.

Q2: What are the signs of failure in an MDI controller?

A2: Some common symptoms of MDI controller failure include increased emissions, harsh engine shutdowns, poor engine performance, and diagnostic trouble codes related to DEF systems.

Q3: Can I upgrade my existing MDI system using MDI controllers?

A3: Yes, upgrading is possible if the current setup is compatible with the aftermarket MDI controller being sought. Aftermarket parts often provide enhanced functionality features alongside improved performance standards.

Q4: Are there any maintenance requirements for MDI controllers?

A4: Yes, controller MDI maintenance involves periodic system checks, software updates, and ensuring good-quality diesel exhaust fluid (DEF). It's also essential to inspect related components, like sensors and pumps, to ensure everything functions properly and avoid potential issues.

Q5: How Should DEF Be Stored?

A5: To maintain DEF quality, store it between 12°C and 30°C. Although urea in DEF does not freeze, if it is exposed to temperatures below 12°C for long periods, it should be tested before use. DEF will remain stable for at least 24 months at this temperature.
