Isotherm SEE00011DA – “Black” Resistance Kit for Medium RPM on Danfoss BD35F / BD50F
The Isotherm SEE00011DA is a medium-speed resistance kit designed for use with Secop/Danfoss BD35F and BD50F refrigeration compressors. Identified within the standard Danfoss speed-select resistor color system as the “Black” resistor, this module sets the compressor to a medium RPM operating level. This provides an ideal balance between cooling capacity and energy efficiency, making it well suited for typical marine refrigeration applications where steady performance and reduced battery usage are required.
The resistor installs directly into the controller’s speed-selection input and requires no calibration or additional configuration. As an OEM-grade marine component, it is engineered to withstand humidity, vibration, and temperature variations frequently encountered on boats and yachts. It is commonly used as a replacement part or when adjusting a system for optimized performance.
