The BITZER IQ MODULE transforms compressors into intelligent, connected system components. It combines monitoring, control, and protection functions in one integrated unit.
The module continuously tracks critical operating data such as temperature, pressure, and motor parameters, enabling reliable system protection and improved operational safety.
Thanks to modular expansion boards, the IQ MODULE can be adapted to different application requirements – from standard refrigeration systems to complex HVAC installations. This flexibility makes it suitable for both new systems and retrofitting projects.
By simplifying commissioning, diagnostics, and service, it reduces installation time and lifecycle costs while increasing system availability.

VARIPACK frequency inverters enable precise, demand-based speed control of BITZER compressors, ensuring optimal system performance under varying load conditions.

By adjusting compressor capacity dynamically, VARIPACK solutions significantly reduce energy consumption and improve overall system efficiency – especially in part-load operation.

Designed specifically for refrigeration applications, these frequency inverters allow fast commissioning, stable operation, and seamless integration into existing control systems.

With protection classes up to IP66 and compatibility with reciprocating, screw, and scroll compressors, VARIPACK is suitable for a wide range of industrial and commercial applications.
