Temperature controls upgraded for washdowns

A new controller added to Mokon's range of temperature systems and chillers is designed to withstand the harsh washdowns used in food plants, its manufacturer claims.

With the increased regulatory emphasis on hygiene in manufacturing plants, equipment makers are upgrading machines to withstand frequent cleanings and harsh chemicals.

Mokon claims its microprocessor-based controller self-tunes using a proportional-integral-derivative (PID) overshoot protection system, providing improved accuracy in temperature readings.

The new device, housed behind a washdown-resistant faceplate, is now standard for all Mokon circulating water and heat transfer fluid temperature control systems and portable chillers.

The controller will provide freeze protection for portable chiller systems and auto air purge for water and heat transfer fluid systems, claims its manufacturer.

A dual computer display on the 1/16 DIN controller, which measures 48mm by 48mm, indicates the set point and the actual temperatures measured.

The controller is compatible with thermocouple sensors, which are cheap, resistance-temperature detectors (RTD), which are known for their excellent accuracy, and milliamp (mA) inputs, which measure an extensive temperature range.

Programmable soft start, which improves energy efficiency, comes as standard on the controller, as well as advanced algorithms to improve cooling, its manufacturer claims.

A parameter password prevents tampering and unintended changes to the controller.

Operators can configure the controller for unique process requirements and view system functions and safeties via scrolling text messages displayed by the unit.

Controllers are also available as 1/8 DIN, measuring 96mm by 48mm, and ¼ DIN, which are 96mm by 96mm. They are available with high/low deviation alarm, remote set point and retransmission and serial communication.

All controllers come with a five-year warranty as standard.

Mokon manufacturers circulating liquid temperature control systems as well as cooling apparatus.
