Isotherm SEE00008DA – “Red” Resistance Kit for Max RPM on Danfoss BD35F / BD50F
The Isotherm SEE00008DA is a dedicated resistance kit engineered to configure the Secop/Danfoss BD35F and BD50F compressors for maximum RPM operation. Known as the “Red” resistor kit, it is part of the standardized Danfoss/Isotherm resistor color coding used to define compressor speed in refrigeration systems. By inserting the resistor into the controller interface, the compressor is driven to its highest operating speed, enabling faster temperature pull-down, rapid recovery after door openings, and maximum cooling capacity—ideal for demanding marine conditions or during heavy load scenarios.
The kit is plug-and-play and can be easily installed on compatible electronic control boards. It provides a reliable performance setting that does not require additional calibration, making it suitable for service, replacements, or system optimization. Built for marine use, the resistor assembly withstands vibration, moisture, and thermal variation.
