The Topchill Air-cooled Semi-hermetic Compressor Chiller (4–80HP) is a water-free cooling solution designed for regions with limited water resources or high water costs. It integrates a semi-hermetic piston compressor, a copper-tube aluminum-fin condenser, and an intelligent control system, delivering reliable cooling capacity from 10.6 kW to 184.2 kW. With a temperature range of +10°C to -25°C, it is widely used in plastic processing, food storage, and small-to-medium industrial workshops, offering the same durability as water-cooled models while eliminating the need for cooling water pipelines.
Water-Free Operation: The copper-tube aluminum-fin condenser (model TQ－NCH series) uses ambient air for heat dissipation, saving 100% of cooling water consumption. This makes it ideal for arid areas (e.g., desert regions) or facilities with high water tariffs.
Durable Semi-hermetic Compressors: The semi-hermetic piston compressor (TQBZ4–TQBW40) features a reinforced cylinder design, supporting 18,000+ hours of continuous operation. Its hermetic structure reduces refrigerant leakage by 90% compared to open compressors.
High Energy Efficiency: Advanced air flow optimization (fan speed adjustment) and a variable refrigerant flow design reduce power consumption by 22%. The unit is certified for low energy consumption by global standards (e.g., CE, UL).
Wide Temperature Range: Operates from +10°C (for beverage cooling) to -25°C (for frozen meat storage), adapting to mixed-temperature industrial needs without additional equipment.
Intelligent Control & Protection: A microprocessor controller manages temperature with ±0.5°C accuracy and provides real-time alerts for fan failure, high pressure, or phase loss. It also supports remote monitoring via a mobile app (optional).
Compact & Easy to Install: The all-in-one design (compressor, condenser, and controller integrated) requires no separate water pipeline installation, cutting installation time by 40%.
This air-cooled chiller series offers cooling capacities from 10.6 kW (4HP, TQ-LSBF04) to 184.2 kW (80HP, TQ-LSBF80), with total power consumption ranging from 4.51 kW to 66.9 kW. The maximum running current is 7.6 A (4HP) to 156 A (80HP), and all models use a 380V/50HZ/3PH power supply. The refrigerant is R22, with a refrigeration circuit of 1 for models below 50HP and 2 for 60HP–80HP. The copper-tube aluminum-fin condenser (TQ－NCH series) has a fan power of 0.36 kW (4HP) to 2.96 kW (80HP) and an air volume of 6,300 m³/h (4HP) to 60,000 m³/h (80HP). The shell-and-tube air cooler uses water or glycol as the secondary refrigerant, with an inlet temperature of 12°C, outlet temperature of 7°C, and a flow rate of 2.4 m³/h to 36.2 m³/h. Connecting pipe sizes range from 1–1/2” to 3”, compatible with standard industrial pipelines.
