Description

The Laboratory Refrigerator CHL 4 ATEX is a professional, explosion-protected cold-storage solution engineered for laboratories and industrial environments where flammable gases, vapors, or volatile substances are present. Designed in compliance with ATEX safety standards, this refrigerator ensures reliable cooling while minimizing ignition risks, making it suitable for use in classified hazardous areas.

The unit provides a stable temperature range of 0 ?C to +15 ?C, allowing secure storage of temperature-sensitive chemicals, reagents, samples, and laboratory materials. A forced air circulation system guarantees uniform temperature distribution throughout the chamber, ensuring consistent cooling performance and rapid recovery after door openings.

Temperature control and monitoring are managed via a microprocessor-based touchscreen controller that offers intuitive operation and precise regulation. All electrical and control components are adapted to meet ATEX requirements, reducing the risk of sparks and ensuring safe operation in explosive atmospheres.

The interior is equipped with energy-efficient LED lighting for clear visibility and durable stainless-steel wire shelves that provide flexible storage configurations and ease of cleaning. Standard safety features include a lockable door system to protect stored contents and an open-door alarm to alert users to unintended access or temperature deviations. An optional external sensor access port supports additional monitoring and compliance needs.

Built with robust materials and designed for continuous operation in demanding environments, the CHL 4 ATEX delivers dependable laboratory-grade performance with enhanced safety. It is an ideal solution for chemical laboratories, pharmaceutical production areas, oil and gas facilities, and industrial research centers that require certified explosion-protected refrigeration without compromising precision or reliability.
