MEIAL Air-Cooled Box Chiller, R22 Refrigerant Industrial Cooling Unit for Aluminum Anodizing & Electrophoresis Line, Multi Safety Interlock Precise Temp Control No Cooling Tower Required

MEIAL air-cooled integrated box chiller eliminates cooling tower & circulating water system investment. Equipped with complete multi-protection circuit, precise constant temperature control within ±5°C, R22 eco refrigerant. Custom cooling tonnage for manual & full-auto aluminum oxidation workshops, solve bath overheating & uneven oxide film defects.

Traditional water-cooled chillers bring multiple hidden costs and production risks to oxidation workshops:

• Extra budget for cooling tower, circulating pump & water pipeline construction, occupying large workshop space;
• Scale blockage, pipeline leakage and winter anti-freezing maintenance raise daily labor & chemical expense;
• Unstable bath temperature caused by poor cooling leads to uneven oxide thickness, color difference and high rework rate;
• Single protection function easily triggers unplanned shutdown during 24h continuous oxidation production.

MEIAL air-cooled box chiller adopts all-in-one cabinet air heat dissipation design, completely cutting tower auxiliary facilities while delivering stable precise cooling for anodizing & electrophoresis processes.

1. Tower-Free Integrated Layout, Cut Upfront Civil Investment
   All refrigeration, pumping and heat dissipation components are pre-installed inside one sealed cabinet. No need to reserve outdoor space for cooling tower, no complicated water pipeline laying, greatly shorten installation cycle and reduce one-time factory reconstruction cost for new oxidation plants.
2. Stable Air Heat Dissipation, Constant Bath Temp To Guarantee Consistent Oxide Film
   Large-area fin condenser + high-speed silent axial fans realize efficient heat exchange. Even long-time high-current hard anodizing production will not cause rapid bath temperature rise, effectively avoid edge thin film, matte spots and color deviation on aluminum profiles.
3. Full Multi-Layer Safety Interlock, Reduce Unplanned Line Shutdown
   Centralized integrated protection system monitors compressor, fan, water pump and refrigerant pressure in real time. Once abnormal parameters appear, automatic alarm and delayed shutdown to protect chiller, rectifier and whole line equipment, minimize production loss caused by sudden equipment failure.
4. Low Maintenance Workload, Save Daily Operation Labor
   Cancel cooling tower cleaning, pipeline descaling and antifreeze maintenance work. Daily inspection only needs to clean condenser surface dust, no special water treatment chemicals required, long-term comprehensive operation cost far lower than water cooling systems.
5. Perfect Matching With Full MEIAL Surface Treatment Equipment
   Seamlessly coordinate with SCR oxidation/coloring rectifier, three-acid mist scrubber, electrophoresis curing oven and wastewater treatment unit. Support one-stop whole workshop layout design, unified delivery, installation and after-sales technical training.
