OverviewClosed-circuit circulating chiller for industrial use providing stable temperatures from -65°C to -20°C while preventing contamination of the heat-transfer fluid.
Key features- Closed-loop pipeline design prevents circulating fluid contamination and extends heat-transfer liquid life.
- Cascade refrigeration architecture with brand compressors (Tecumseh / Copeland) and an efficient two-condensate system.
- ASET multifunctional controller with PT100 sensor and 7-inch color touch screen; temperature resolution 0.1°C; temperature curve recording and Excel export.
- Computer-cascade temperature control; adjustable compressor on/off differential; monitoring of ambient temperature to protect system stability.
- High-performance circulating pump for 24/7 operation; available pump options for higher flow/pressure.
- Comprehensive safety package: multi-level protections and alarms (over-temperature, sensor fault, high pressure, compressor overheat, liquid level), power-on delay and equipment grounding.
- Plate heat exchanger and copper-tube evaporator for effective heat transfer; refrigerant R-404A.
Technical specifications- Series / models: LRC-65 Series — LRC-6018, LRC-6030, LRC-6062, LRC-6090, LRC-60A1, LRC-60A2.
- Temperature range: -65°C to -20°C.
- Controller: ASET multifunctional controller; PT100 feedback; MODBUS RTU (RS-485) communication.
- Cooling capacity examples: at -20°C: 0.85–7.2 kW; at -40°C: 0.7–6 kW; at -55°C: 0.4–3 kW (varies by model).
- Circulation: pump flow up to 75 L/min and ~1 BAR typical depending on model; storage capacity 15–45 L (model dependent).
- Evaporator: copper tube; refrigerant: R-404A; construction: cold-rolled steel with paint (SUS304 optional).
- Power & dimensions: model-dependent (AC220V 50Hz for some models; AC380V 50Hz typical; optional 220V/60Hz or 440–480V/60Hz three-phase).
Options & customization- Circulation pump upgrades: 35 L/min, 50 L/min, 110 L/min at 2.5 bar; high-pressure pumps up to 6 bar; SUS304 construction option.
- Alternative power configurations and increased liquid storage available on request.
Applications- Low-temperature industrial testing, laboratory cooling, material conditioning and processes requiring contamination-free closed-loop cooling.
