PAMEL PRD2U power and temperature controller (up to 2 probes)

PRD2U+ – power and temperature controller for smoking, distilling, and other applications

PRD2U+ from a Polish company PAMEL is a universal controller designed for precise control heating power and temperature. Depending on the version, the device can control receivers with power up to 5.5 kW, making it suitable for both home applications and more demanding technological processes. PAMEL positions this series as a solution for smoking, distilling, brewing, tank heating, and other processes where stable heater operation and temperature control are essential.

The greatest advantage of the PRD2U+ is its practical versatility. Without connected probes, the device operates like a classic power controller, allowing you to conveniently set the heating power percentage. After connecting the stainless steel probe with a 1.8 m cable the controller becomes a device for controlling power and temperature, giving the user significantly greater control over the process. This is how the manufacturer describes the PRD2U+ on the product page and in the series manual.

One device, multiple operating modes

The PRD2U+ can be adapted to various user needs. Without the probes, it works as a simple power controller. With one probe, it allows you to control the process temperature. With two probes, it offers even greater possibilities, as the second probe can perform not only a measuring function but also terminate the process when the set alarm temperature is reached ThisThe manufacturer describes this solution as particularly useful in smoking and distilling.

The controller offers power regulation resolution of 0.25%, which allows for very precise adjustment of the heater's operation to a specific application. According to the current PRD2U+ series manual, the temperature setting range is 10 to 130°C, and the temperature measurement resolution is 0.05°C. This is important because your sketch shows 10–115°C, while the newer PAMEL manual for the PRD2U/PRD2U+ series specifies 10–130°C.

Second probe and automatic process termination

A major advantage of the PRD2U+ is the ability to connect a second probethat can automatically stop the process once the set temperature is reached. This. This is a very practical solution for applications where stopping work at the exact right moment is crucial.

In smoking , a second probe can monitor the temperature inside the meat. When the product reaches a preset value, for example, Ta = 80°C, the controller can end the heating process. In distillation , a second probe can monitor the temperature in the keg or another important point in the process, and when a preset threshold is reached, for example, Ta = 90°C, the device can trigger an alarm and stop further operation. Such examples are provided directly in PAMEL materials.

When the set temperature is exceeded, the device triggers an audible alarm. To resume operation, simply press the center button, which turns off the alarm. The controller operates with an approximately 30-second delay, allowing time to change the settings if necessary. The manufacturer also indicates the availability of a version with remote alarm notification.

Smoker Application

The PRD2U+ works very well in electric smokers. The Smoking category on pamel.pl includes this series as one of the basic solutions for controlling heaters and process temperature. The controller can operate both as a simple power controller and as a device for maintaining the chamber temperature. By connecting a second probe, it can additionally monitor the temperature inside the product and help complete the process precisely at the right time.

In practice, this means greater convenience and improved repeatability. The user can control the chamber temperature, limit the maximum batch temperature, and better manage the entire process without constant manual supervision.

Uses in Distillation

The PRD2U+ is also widely used in distillation. The Distillation category on pamel.pl describes PAMEL controllers as solutions that ensure stable heater operation and precise temperature control on the column and in buffers. The PRD2U+ is well-suited for this method of operation, allowing both heating power regulation and temperature control using probes.

In distillation, the controller can be used to smoothly adjust the heater power, stabilize the process, and terminate operation after reaching a set alarm temperature. The PAMEL manual also notes that the process termination temperature should be determined based on actual device operation, and that "water" tests do not accurately reflect alcohol conditions.

Use in brewing and other processes

PRD2U+ will also be useful in brewing, for tank heating, and in various heating systems and anywhere stable power or temperature control is needed. PAMEL's power and temperature controllers category describes these devices as intended for smoking, distilling, brewing, tank heating, and other technological processes.

It's simply a universal tool for those who want more control over the heater than a standard power controller without the need for a complex industrial controller.

Easy Installation and Convenient Operation

The PRD2U+ has been designed for quick and intuitive operation. The device features a clear LCD display, a simple control system, and easy installation. The ability to operate with one or two probes allows for a configuration tailored to the user's needs. This is especially important if someone wants to start with a simple system and later expand it with additional temperature control functions. The manufacturer's description emphasizes this flexibility of use.

Operational Safety

The PRD2U+ is equipped with overcurrent protection and thermal protection. The device also features forced cooling using a built-in fan. The current series manual also lists a self-extinguishing housing, an IP20 protection rating IP20 and a warranty of 60 months from the date of sale.

Key Advantages of the PRD2U+

The PRD2U+ combines ease of use with extensive functionality. It can operate without probes as a power regulator or with probes as a power and temperature regulator. It offers precise power control 0.25%, supports up to 2 probes, allows for setting an alarm temperature This, has an audible alarm, and is suitable for smoking, distilling, brewing, and other heating processes. The maximum power of the PRD2U+ version is 5.5 kW.
