Explosion Showcase: Model: BL-900 features: Explosion refrigeration power: 220/50 (V / Hz) Rated power: 550W Noise: ≤41 (db) Power consumption: 5.5 (Kw.h / 24h) Protection against electric shock Category: I always effective volume: 900L freezer capacity: 900L freezer temperature: 0-10 ℃ refrigerant: R134a Net Weight: 195kg proof mark: ExdmibII BT4 Dimensions (W * D * H): 1220 * 665 * 2190 ( mm) Cooling method: air-cooled frost-free, temperature display (Note: According to customer requirements, the actual standard) Product Features: 1. brass fin condenser, forced ventilation, cooling rapidly 2. The maximum surface temperature limit protection technology and a variety of security technologies. 3. Explosion full CNC digital refrigerator temperature accuracy ± 5 ℃, with fault overtemperature alarm. 4. Using the box outside the box full proof in the form, not only can store all kinds of dangerous goods inside, and can be placed in the freezer explosion hazardous areas. 5. Press Zone 0 design, produce and meet the GB3836.14 GB3836.15 mandatory national standard products can store all kinds of dangerous goods. 6. refrigeration system uses "tightness" proof and "positive pressure" proof composite structure, the inside zone 0 according to the requirements of the design, meet the latest safety regulations. 7. The control circuit leading international microwatt level full optical isolation intrinsically safe circuit, the safety factor higher than the internationally recognized security of energy three orders of magnitude or more. Scope and explosion-proof refrigerator principle: Explosion showcase mainly used in petroleum, chemical, military, medicine, scientific research, laboratory and other fields, for cooling the storage of drugs and other agents at lower temperatures do not keep at room temperature volatile flammable dangerous goods. Its structure divided into single doors, double doors and more doors and horizontal and vertical points. It consists of the refrigeration compressor, a condenser, a condenser blower, an evaporator, a temperature controller. To make it safe for use in hazardous locations, we also employ complex technology explosion-proof freezer were processed. Compressor, condenser fan using encapsulation or flameproof technical processing, as a passive temperature control switch with active opto-proof solid-state relays intrinsically safe automatic temperature control system. To protect the compressor will not be damaged, the use of delayed-proof solid-state relays and overload protection and thermal protection devices, the use of explosion-proof electrical part of the control handle. In order to prevent the harm caused by static electricity, for display cabinet conductive paint spray chamber to eliminate electrostatic effects, use more secure.
