Labmate Explosion‑Proof Refrigerated and Heating Circulator LMERH‑A101

Labmate Explosion-Proof Refrigerated and Heating Circulator LMERH-A101

Overview:
The Labmate Explosion-Proof Refrigerated and Heating Circulator LMERH-A101 is a dual-mode temperature control system designed for precise and safe operation in hazardous and flammable environments. Combining water-cooled refrigeration and high-temperature heating within an explosion-proof platform, it delivers reliable performance across a wide range from –30 °C to 200 °C. The unit supports external fluid circulation for reactors, pilot-scale processes, and thermal testing, ensuring stable, accurate, and safe temperature control for laboratory and industrial applications.

Key Features:
• Explosion-proof construction for hazardous zones
• Dual refrigeration and heating capability with water-cooled system
• Wide working temperature range: –30 °C to 200 °C
• Real-time fluid level monitoring to prevent dry-run conditions
• Large, color LCD display for clear temperature and system status
• Safety protections for over-pressure, leakage, overload, and electrical faults
• USB, RS485, and Pt100 interfaces for external control and data access
• Stable operation with controlled temperature transitions and low noise (~65 dB)

Applications:
• External temperature control for laboratory reactors and pilot lines
• Heating and cooling for chemical synthesis, fermentation, and extraction processes
• Thermal conditioning in pharmaceutical, biotechnology, and food processing
• Hazardous-area thermal management and quality control
