Air cooler LRC series

for refrigerationfor circulating bathsfor the pharmaceutical industry

Product overview
Compact low-temperature circulating chiller for laboratory and industrial bench applications. Compressor-cooled unit with integrated bath for direct immersion or external circulation. Temperature performance varies by model, with ranges from typical -20°C down to -50°C and temperature control accuracy to ±0.1°C (model-dependent). Designed for continuous operation and process cooling tasks.

Key features

• Dual operation modes: external circulation or open bath for direct immersion
• Vertical footprint for space-efficient installation; user-friendly interface
• Non start-stop refrigeration combined with microprocessor PID control for rapid, stable temperature control
• Display of temperature, pressure and liquid level; software lock to protect settings
• Enclosed air-cooled compressor with delay, overheat and over-current protection for reliable service
• Bath and condenser manufactured in SUS304 stainless steel; multiple stainless steel interfaces and hose fittings available
• Suitable for continuous 24×365 operation where specified

Applications
Engineered for low-temperature laboratory processes and industrial bench usage: rotary evaporators, fermenters, low-temperature chemical reactions, biopharmaceutical reactors, analytical instruments and other applications requiring precise temperature control of circulated fluids.
