• REFRIGERATED DC COMPRESSOR

    -- Powering Compact & Lightweight Refrigeration Systems

    RIGID Miniature Refrigerated Compressors are engineered to deliver high cooling capacity, precise temperature control, and exceptional power density in an ultra-compact form factor. Designed for modern mobile, portable, and space-constrained refrigeration systems, these miniature DC compressors enable powerful thermal management solutions while remaining discreet, lightweight, and energy efficient.

    Since 2010, RIGID has led innovation in miniature rotary compressor technology, developing compressors up to 10× smaller and lighter than traditional units with comparable cooling capacity. This breakthrough allows product designers to focus on system performance and differentiation — while the compressor quietly does its job in the background.

    Your product will stand out. Your compressor will go unnoticed.
