Core Working Principle
Only sensible heat exchange, NO latent cooling & zero condensate:
Supply chilled water temp is controlled 1~2℃ higher than indoor air dew point, coil outer surface never drops below dew point → no water condensation on fin/tube surface.
Remove only room sensible load: equipment heat, lighting & human heat; indoor RH stays stable (humidity load fully undertaken by MAU fresh air unit).
Matches classic cleanroom system: MAU+FFU+DCC, mainstream for ISO5~ISO8 clean workshop.
Standard Chilled Water Spec
Typical supply/return: 16℃ /21℃ medium temp chilled water (custom per site dew point calculation).
Construction & Material (Cleanroom Grade Full Stainless Steel)
Component | Material | Cleanroom Design Feature |
|---|---|---|
Heat exchange tube | SUS304 / SUS316 stainless seamless tube, OD9.52/12.7mm, wall≥0.45mm | Anti-corrosion, no rust flake falling to contaminate clean air |
Cooling fin | Epoxy coated aluminum / full SS fin option | Smooth surface, low dust adhesion, easy CIP cleaning |
Header & manifold | SUS304 stainless steel | Welded seamless, pressure tight |
Outer frame & drip tray | SUS304 stainless | Sloped drain pan (DN20 drain port) for rare accidental condensate discharge |
Auxiliary fitting | SS air vent + drain valve on inlet/outlet | Automatic air exhaust for stable water circulation |
Tube-fin connection: hydraulic expansion for tight contact, high heat transfer efficiency.
Factory pressure test: 1.5×design working pressure hold 24h before delivery.
Core Advantages for Cleanroom Application
Zero condensate risk: Eliminate mold/bacteria breeding from condensed water, meet GMP/pharma/semiconductor clean standard
Humidity & temperature decoupling: MAU controls RH, DCC controls room temp; ±0.1℃ precise temp control for precision production
Low maintenance: Smooth SS structure, less dust deposit, convenient periodic compressed-air cleaning
Space flexible: 3 installation styles: ceiling suspended, vertical cabinet, horizontal duct-mounted
