The Lytron RC045 is a recirculating chiller engineered for demanding industrial and laboratory environments requiring precise temperature management. This semi-hermetic, oil-free unit delivers 5900 W (20.1 kBTU/Hr) cooling capacity with ±0.1°C temperature stability, making it ideal for heat-sensitive equipment in laser cooling, analytical instrumentation, and process control applications. The split-chassis, modular design incorporates a recirculating heat exchanger and 1.5 HP semi-hermetic compressor optimized for reliability and low maintenance.
Technical Specifications
• Cooling Capacity: 5900 W (20.1 kBTU/Hr) at 60 Hz; 17% reduction at 50 Hz
• Compressor: 1.5 HP, semi-hermetic, oil-free
• Temperature Stability: ±0.1°C
• Coolant Temperature Range: 5°C to 35°C (40°F to 95°F); freezing point depressant required below 10°C
• Ambient Temperature Range: 10°C to 35°C (50°F to 95°F)

– Key Features
• Multiple pump options: positive displacement (4.3 GPM / 16.3 LPM), centrifugal, and turbine configurations rated at 60 Hz
• Integrated temperature and humidity probe with real-time ambient feedback
• Low-side pressure transducer for system monitoring
• Electronic control box with digital display (°C/°F selectable), ±0.1°C precision control, and temperature/airflow/power readings
• Alarm functions: low level, low/high temperature, fault shut-off, and low flow shut-off
• Configurable relay contacts (NO/NC)
• Optional RS-232 communication
• Compressor and pump vibration isolation with foam-padded panels for noise reduction
• Sight glass window for condenser performance monitoring
– Typical Applications
Laser cooling systems, analytical instrumentation, precision process temperature control, and laboratory environments where consistent thermal management is critical.
– Compatibility & Integration
Fluid connections accept 1/2″ FNPT fittings. Cartridges are not recommended with centrifugal and turbine pump options. Filtered clean water is required for operation above 10°C; ethylene glycol or equivalent freezing point depressant must be added for sub-10°C operation.
