KRIWAN Diagnosis System

 

 

Kriwan Diagnosis Systems 
The basis for comprehensive diagnosis:
Precise and secure protection: 
The KRIWAN Diagnosis System is a milestone in the development of compressor protectors. The system offers communication capabilities for comprehensive and detailed diagnosis and analysis in addition to proven monitoring and protection features.

Accurate measurements are a prerequisite for the efficient diagnosis of your system's operation. KRIWAN diagnosis motor protectors reliably provide relevant information about any compressor.They continuously monitor parameters such as motor temperature, current consumption, phase status, oil (pressure, level, temperature) and discharge gas temperature. Possible shorts and discontinuities are detected and saved to memory for later evaluation. Separate inputs enable selective detection, evaluation, and responses, for targeted intervention at any time.

Take advantage of the excellent KRIWAN diagnosis control and protection system for your refrigeration units.

Benefit : 
***  Storage of all relevant compressor data
***  Comprehensive functionality: Blockage detection; individual delays; current measurement; protection against abnormal operation 
***  Early fault detection Available for nearly any compressor

Easy access to diagnosis data:
User-friendly interfaces and communication
Communication interfaces turn the KRIWAN Diagnosis System into a comprehensive source of data about a refrigeration system. The well-designed and standardized system is easy to use: On site, data can be accessed directly at the compressor via USB or Bluetooth using a smartphone, a tablet, or a laptop.

For permanent integration of all compressors into the system controller, the INT600 DM® Gateway provides a Modbus interface.
The Modbus-LAN Gateway periodically sends the data to a server for web-based diagnosis and analysis. From there, they can be accessed from any Internet-capable device via a web portal. Of course, both devices can be easily refitted at any time.

Benefits 
***  Standardized interfaces & protocols
***  Easy integration into control systems
***  Available worldwide via Internet
***  Easy refitting


For clear analysis:
Diagnosis software with a well-structured visualization

KRIWAN has an innovative solution for visualizing operation and diagnosis data:

The INTelligence web portal displays all parameters in a clear and organized manner, for easy interpretation of, for example, switch cycles, runtime, or temperature. The intuitive comparison features enable the instant comparison of several compressors or systems. The collected error messages provide more detailed insights into the condition of the system. Significant changes due to wear, changed operating conditions, or other causes can be detected in time by observing trends based on documented long-term data.

The KRIWAN Diagnosis System can be integrated into the system controller via Modbus. The evaluation is implemented in the controller, where it enables advanced compressor diagnosis for power management and system optimization, as well as detailed fault analysis.

Quick, efficient, proactive, sustainable:
a diagnosis system that thinks ahead
Building on a long tradition in compressor protection, KRIWAN has set a course for the future with its Diagnosis System. Thanks to precise, reliable measurements and analysis, errors and their root causes are instantly detected.

The advanced KRIWAN diagnosis technology provides direct access to compressor data and a comprehensive analysis of system parameters. This turns a compressor into a source of data about your refrigeration system.

Quick – fault detection
***  Efficient troubleshooting
***  Root cause and fault time detection
***  Early detection of out-of-range errors (e.g. refrigerant low, condenser pollution, faulty defrosting of key components)

Efficient – fault correction
***  App interface
***  Error memory

Proactive – error prevention
***  Focused maintenance
***  Evaluation of compressor load

Sustainable – longer system service life, reduced environmental impact
***  Reduced CO2 emissions through minimized power consumption
