Labmate Explosion-Proof Refrigerated and Heating Circulator LMERH-A109

Labmate Explosion-Proof Refrigerated and Heating Circulator LMERH-A109

Overview:
The Labmate Explosion-Proof Refrigerated and Heating Circulator LMERH-A109 is a high-capacity, dual-mode temperature control system designed to provide both refrigerated cooling and high-temperature heating in hazardous and flammable environments. Engineered with explosion-proof electrical systems and robust safety protections, it delivers stable thermal management across a working range of –30 °C to 200 °C. The large fluid capacity and powerful thermal performance make this model ideal for external circulation in reactors, pilot-scale processes, semiconductor and vacuum systems, and material testing in chemical, pharmaceutical, and energy applications.

Key Features:
• Explosion-proof construction for safe use in hazardous zones
• Wide dual cooling and heating range from –30 °C to 200 °C
• Large 18 L fluid reservoir for extended thermal runs
• High-flow circulation at 45 L/min for efficient heat transfer
• Water-cooled refrigeration system for stable cooling performance
• Intuitive 7-inch LCD display for monitoring temperature and system status
• USB, RS485, and Pt100 interfaces for external control and integration
• Multi-layer safety protections for overheat, pressure, leakage, overload, and electrical faults
• Sealed fluid circuit to reduce fluid loss and maintain reliability
• Emergency stop and reset switches for safe operation

Applications:
• External temperature control for reactors and pilot production lines
• Heating and cooling for semiconductor and vacuum tools
• Thermal management in fermentation, extraction, and process testing systems
• Hazardous-area environmental simulation and quality assurance
