Description
The Laboratory Refrigerator CHL 3 ATEX is a high-performance, explosion-protected cold storage solution engineered specifically for hazardous environments where flammable gases, vapors, or combustible dust may be present. Certified to meet ATEX safety standards, this refrigerator delivers dependable, uniform cooling while minimizing ignition risks, making it ideal for use in chemical plants, refineries, pharmaceutical facilities, oil & gas laboratories, and other industrial settings.
Designed to maintain a stable temperature range of 0 ?C to +15 ?C, the CHL 3 ATEX supports safe storage of temperature-sensitive samples, chemicals, reagents, and other materials requiring controlled refrigeration. The unit?s forced air circulation system ensures even temperature distribution throughout the chamber, reducing hot spots and enhancing overall temperature stability.
Control and monitoring are managed through a microprocessor-based touchscreen controller engineered for intuitive operation and precise temperature regulation. All electrical components and user interfaces are adapted to comply with ATEX safety criteria, reducing the potential for sparks and ensuring safe performance in classified zones.
The interior is equipped with internal LED lighting for clear visibility and stainless-steel wire shelves that provide durable, adjustable storage. Standard safety features include an open-door alarm to alert users to accidental openings or temperature excursions and a door lock to secure valuable contents. An external access port enables integration with optional sensors or third-party monitoring devices.
Constructed with robust materials and designed to withstand the demands of hazardous work environments, the CHL 3 ATEX combines laboratory-grade performance with enhanced safety. Its explosion-protected design allows laboratories and industrial facilities to implement critical refrigeration solutions where standard equipment may pose a risk, delivering reliability, precision, and compliance in one certified system.
