The Danfoss 104L2197HS Compressor (also recognized as the Secop SC21CL) is a high-performance light commercial reciprocating compressor engineered for low back pressure (LBP) applications. Designed specifically for R404A and R507 refrigerants, this unit is a staple for refrigeration contractors managing commercial freezers, cold rooms, and display cases. It operates on a 220-240V 50Hz single-phase power supply and features a robust 20.95 cm³ displacement. This model utilizes Capacitor Start Run (CSR) motor technology, providing the high starting torque (HST) necessary to handle demanding pull-down cycles in high-ambient environments. With POE oil pre-charged for moisture-free operation and a compact hermetic design, the 104L2197HS ensures reliable thermal management in systems requiring precision cooling. Refrigerant Compatibility: Optimized for R404A/R507 systems, ensuring high volumetric efficiency. Robust Motor Design: Features a high-torque CSR motor to handle frequent cycling and low-temp start-ups. Thermal Stability: Engineered for Low Back Pressure operations with effective fan-cooled heat dissipation. Technical Reliability: Constructed with Polyolester (POE) oil for superior lubrication and system longevity. Contractor Ready: Standardized mounting and electrical connections for streamlined onsite replacement projects. Common Questions What is the displacement and oil type for this model? The 104L2197HS features a 20.95 cm³ displacement and is filled with POE (Polyolester) oil, which is essential for compatibility with HFC refrigerants like R404A. Is this compressor suitable for high-temperature applications? No, this is an LBP compressor designed for low-temperature applications such as freezers. Using it for high back pressure (HBP) can lead to motor overheating and premature failure. What is the required starting torque? This unit is an HST (High Starting Torque) model, utilizing a start capacitor and relay to ensure reliable start-up against high pressure differentials. This item is not eligible for free shipping.
