The Topchill Water-cooled Semi-hermetic Compressor Chiller (4–100HP) is a robust industrial cooling solution engineered for continuous operation in harsh environments. It features a semi-hermetic reciprocating compressor—known for long service life—and a high-efficiency shell-and-tube condenser, delivering stable cooling capacity for plastic processing, food production, and chemical industries. With a temperature range of +10°C to -25°C, it meets both medium and low-temperature application needs, while its compact design saves 30% of installation space compared to traditional water-cooled chillers.
Reliable Semi-hermetic Compressors: The semi-hermetic reciprocating compressor (models: TQBZ4–TQBW50) is designed for 20,000+ hours of trouble-free operation. Its hermetic structure prevents refrigerant leaks, reducing maintenance frequency by 50%.
Superior Energy Efficiency: Advanced refrigerant throttling (external balanced temperature-sensing thermal expansion valve) and optimized heat exchange design reduce power consumption by 25% while maintaining stable cooling capacity.
Wide Temperature Adaptability: Operates seamlessly from +10°C (for dairy processing) to -25°C (for frozen food storage), eliminating the need for multiple chillers in mixed-temperature facilities.
Intelligent Precision Control: A microprocessor-based controller manages temperature with ±0.3°C accuracy. It also provides real-time alerts for abnormalities (e.g., high/low pressure, water flow loss), protecting the system from damage.
Space-Saving Compact Design: The integrated layout (compressor, condenser, and controller in one unit) reduces installation space by 30%, making it ideal for factories with limited floor area.
Comprehensive Safety Protections: Equipped with 8+ safety devices, including compressor overheat protection, power phase-loss protection, and cold water over-low temperature protection, ensuring 24/7 safe operation.
This chiller series covers a cooling capacity range of 11.2 kW (4HP, model TQ–LSB04) to 245.6 kW (100HP, model TQ–LSB100). Total power consumption ranges from 3.58 kW to 66.9 kW, with a maximum running current of 7.6 A to 184 A (all models use 380V/50HZ/3PH power supply). The refrigerant is R22 (environmentally compatible with Freon systems), and the refrigeration circuit is 1 for models below 50HP and 2 for 60HP–100HP (ensuring redundancy). The shell-and-tube condenser has a water inlet temperature of 30°C and outlet temperature of 35°C, with a water flow rate of 3 m³/h (TQ–LSB04) to 60.4 m³/h (TQ–LSB100). The air cooler (shell-and-tube type) 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 46.4 m³/h. Connecting pipe sizes range from 1–1/2” to 4”, compatible with standard industrial pipelines.
