Danfoss introduces variable-speed VZH compressor management

Danfoss has upgraded its MCX15B and MCX20B controllers with the introduction of the MCX15B2 and MCX20B2 controllers. Both models combine best-in-class connectivity, security, and performance with improved compressor control logic for VZH inverter scroll compressors.

Danfoss' MCX15B2 and MCX20B2 controllers provide several key benefits that mitigate the industry's most common pain-points when designing connected HVAC systems and smart buildings. These new controllers go beyond and deliver embedded connectivity, stronger web security, and enhanced performance.

To advance WEB server and TCP protocol connectivity, the MCX15B2 and MCX20B2 controllers are ethernet-enabled with web server features and Modbus/TCP protocol, CAN bus as a fieldbus towards other controllers, remote user interfaces, up to two Modbus RS485 opto-isolated serial interface, and USB access for easy software uploading and datalogging.

The MCX15B2 and MCX20B2's basic architecture and increased safety monitoring ensure a solid security base. Secure protocols, cipher suites, protected keys and certificates, strict user and access authorization, strong safeguarding policies, and frequent safety updates allow you to track and respond to security threats quickly and easily.

With the increased capacity and speeds available for customer software applications, managing additional languages, datalogging, and the creation of webpages, the MCX15B2 and MCX20B2's enhanced performance shines above both its predecessors and the next best alternatives currently on the market.

The MCX15B2 and MCX20B2 controllers deliver the industry's best-in-class compressor management for VZH scroll compressors. They perform time- and level-based functions for both envelope and discharge gas temperature control and single oil management, such as generating alarms and increased speed and maintenance when necessary.

In short, with its connectivity, security, and performance enhancements, These programmable controllers deliver improved energy efficiency, comfort, flexibility, and faster assembly times for your HVAC systems and smart buildings.
