Explosion-Proof Refrigeration for Safer Operations: Shanghai Kub Refrigeration Powers Temperature Control in Biopharma

Shanghai KUB Refrigeration Equipment Co.,Ltd. — a source manufacturer with over two decades of expertise, delivering integrated explosion-proof cooling solutions In biopharmaceutical, fine chemical, lithium battery material and electrolyte production, as well as hazardous-chemical cold storage, refrigeration equipment must do more than deliver precise temperature control — it must eliminate every potential ignition source, from electrical sparks to hot surfaces. With more than twenty years of hands-on experience as an integrated manufacturer and trader, Shanghai Kub Refrigeration EquipmentCo., Ltd.has become a long-term designated supplier for demanding temperature-control applications across these high-risk sectors.

1. A True Source Manufacturer: R&D, Production and Installation Under One Roof
Founded in March 2000 and headquartered in Jiading District, Shanghai, with registered capital of RMB 5 million, Shanghai Kub  Refrigeration owns its proprietary brand  “KUB”and holds multiple independent  patents, including “A Refrigeration Unit,” “Semi-Hermetic Medium-Temperature Screw Condensing Unit” and “Energy-Saving Refrigeration Unit for Cold Storage.” The company integrates R&D, manufacturing, sales and engineering installation, controlling the entire chain from compressor selection and unit fabrication to cold storage design and
installation. Its products have served major projects such as the Beijing Olympic Games and Shanghai World Expo, and are exported to over a dozen countries across South America,
the Middle East and Europe. For core components, Kubao distributes world-renowned compressor brands including Carrier, Bitzer, Danfoss and Emerson, complementing its own product lines and enabling flexible configuration for virtually any operating condition.
2. Explosion-Proof Units: Engineered to Hazardous-Area Standards, Balancing Safety and Efficiency
Kub’s explosion-proof refrigeration units are designed and electrically configured in strict accordance with codes for explosive atmospheres. Electrical components feature flameproof and increased-safety protection, and explosion-proof ratings can be customized to the site’s hazardous-area zone classification (e.g., Zone 1 or Zone 2) and gas group — making them suitable for storage and production environments containing flammable gases or vapors.

The product portfolio includes:
Air-cooled explosion-proof condensing units: Multiple series including Tecumseh piston-based explosion-proof air-cooled units, Copeland open-type air-cooled explosion-proof units, U-type box explosion-proof heating/cooling units and V-type box explosion-proof units, covering a wide range of capacities — from low-temperature laboratory cold rooms to large hazardous-chemical warehouses; Explosion-proof unit coolers: Available with hot-gas defrost, which uses the sensible and latent heat of compressor discharge for rapid evaporator defrosting — significantly reducing energy consumption and temperature fluctuation compared with conventional electric defrost. This is critical for temperature-sensitive, fire-prohibited materials such as electrolytes; Explosion-proof heating/cooling units: Providing both cooling and heating from one unit for chemical materials requiring anti-solidification in winter and cold storage in summer; Cascade ultra-low-temperature units: Delivering -60°C to -80°C through optimized multi-stage compression cycles, serving deep-freeze storage and process cooling for specialty pharmaceutical intermediates and lithium battery materials.

3. Four Industry Scenarios, Precisely Matched Pain Points
Biopharmaceuticals: Vaccines, biologics, plasma, strains and APIs demand stringent storage temperatures (2–8°C, -20°C, -40°C or even -80°C), where cleanliness and operational stability are non-negotiable. Kubao provides multi-temperature-zone explosion-proof unit and cold-room solutions with intelligent control and remote monitoring, supporting
GSP/GMP-compliant warehousing. Fine chemicals: Production involves large volumes of flammable and explosive raw materials and intermediates; both feeding and finished-goods storage require reliable low-temperature and explosion-proof protection. Kub customizes evaporating temperature and refrigerant schemes based on medium characteristics, covering both process cooling and storage refrigeration. Lithium battery materials and electrolytes: lectrolyte solvents such as carbonates have low flash points and high volatility, requiring
continuous low-temperature storage free of ignition sources; processes involving NMP and cathode/anode materials likewise demand stable cooling. Kubao’s explosion-proof units
and unit coolers operate reliably in electrolyte tank farms and lithium battery material warehouses, safeguarding safe production across the new-energy supply chain.
Hazardous-chemical cold storage: For hazardous-chemical warehouses, Kub offers end-to-end delivery from unit selection and explosion-proof electrical configurati
