Wide range of applications from light commercial to medical. Typical application scenarios include: supermarket island freezers, glass door display cabinets, beverage dispensers, drink coolers, commercial refrigerators/freezers, vending machines, ice cream display cabinets, air curtain cabinets, cold room integrated units, heat pumps, ULT freezers, biomedical freezers, and other medium-to-low temperature refrigeration equipment.
Technology and flexible start-up configurations provide equally reliable deep-freezing capability.
Selection logic:
Small beverage coolers, vending machines, light display cabinets → SC12FT
Medium commercial freezers, air curtain cabinets, ice makers → SC15FT
Ice cream display cabinets, supermarket island freezers, cold room integrated units → SC18FTX
Large frozen display cabinets, biomedical freezers, heat pumps, ULT equipment → SC21FTX
SC12FT — Compact Light Commercial First Choice
Features: 12.87 cm³ displacement, LBP 321W, height only 209 mm, weight 12.7 kg
Advantages: Compact size, low cost, energy-optimized for small vending machines / beverage coolers / light display cabinets, making it a cost-effective choice for low-capacity applications
SC15FT — The Versatile Mid-Range Workhorse
Features: 15.28 cm³ displacement, available with four electrical configurations including CSIR (HST) and RSIR (LST), single pack includes start relay + 80 μF start capacitor
Advantages: Most flexible configuration, supports both hot gas defrost and long interval pull-down, compatible with virtually all medium-sized commercial freezers, air curtain cabinets, ice makers, and glass door display cabinets
SC18FTX — Tropical Deep-Freeze Powerhouse
Features: 17.69 cm³ displacement, marked as "Tropical Compressor", CSIR high starting torque, maximum condensing temperature 60°C (short-term 70°C)
Advantages: Stable deep-freezing performance even in high-temperature, high-humidity environments such as Southeast Asia and the Middle East; ideal for supermarket island freezers, ice cream cabinets, and cold room integrated units
SC21FTX — Series Flagship
Features: 20.95 cm³ displacement, LBP cooling capacity 569W, CSIR start, 13.7 kg, dual voltage versions: 220-240V/50Hz and 208-230V/60Hz
Advantages: Maximum single-stage deep-freezing capability achievable with R134a, suitable for large frozen display cabinets, heat pumps, biomedical freezers, and other applications demanding high cooling capacity
Q1: What refrigerant are these four compressors designed for? Can they be converted to use R290 or R404A?
A: SC12FT / SC15FT / SC18FTX / SC21FTX are designed for R134a only.
Q2: How do I select the voltage/frequency? Are they globally compatible?
A: These four models mainly cover two versions:
220-240V / 50Hz (Europe, China, Middle East, etc.)
208-230V / 60Hz (North America, Latin America, etc.)
Q3: What does the "FTX" suffix stand for? What is the difference between FT and FTX?
A: FTX stands for Tropical Enhanced Version (Tropical Compressor).
