Frameless Labyrinth Casing to EN 1886
A new-generation frameless design: high-strength ABS composite profiles and a forced-seal compression labyrinth lock every panel tight.
- Air leakage class L1, thermal transmittance T2
- Thermal bridging TB1, casing strength D1 (EN 1886:2007)
- Leakage only ~9% of the Chinese GB limit for purification units
- Smooth arc inner walls — no hard-to-clean corners
Clean, Aseptic-Ready Interior
An adhesive-free fillet seal and flat interior leave nowhere for dust to settle, making the unit suitable for aseptic clean spaces.
- Non-toxic, antibacterial soft colloid sealant exported to the EU
- Silicone-free, resistant to high humidity and temperature
- Optional stainless-steel drain pan
- Optional hydrophilic aluminium fins
Multi-Stage Filtration
High-quality filters from well-known domestic and international brands, on sliding pull-out frames for easy service.
- Pre-filter: nylon, G3 / G4 plate or metal filter
- Medium-efficiency F5 / F6 bag filter
- Optional activated carbon or electronic electrostatic purifier
- Large dust capacity, low resistance, long service life
Four Standard Layouts
Choose the section line-up that fits the application — horizontal or vertical, return air or fresh air.
- H1: pre-filter + cooling coil + fan
- H2: mixing box + G3/G4 filter + coil + fan
- H3: mixing box + G3/G4 + F5/F6 bag filter + coil + fan
- V1: vertical type for compact plant rooms
AMCA-Certified, Low-Noise Fans
Brand-name centrifugal fans are selected for quiet running and mounted on a rigid welded steel frame.
- AMCA certified, impeller balanced to G4.0
- Hot-dip galvanized shell, cold-rolled steel impeller
- High-quality ball or roller bearings
- External static pressure up to 570 Pa
AHRI-Verified Coil Selection
Professional coil software selects the optimal coil for low water and air resistance and low energy use.
- Selection compliant with US AHRI certification
- Four chilled-water coil types: C, D, E, F
- Cooling 8.6 – 419.3 kW (standard condition)
- Optional hot-water heating coil, type A or B
Start-up Cabinet & Intelligent Control Box
From a simple machine-room starter to automatic room-temperature control linked to the BAS.
- Local start/stop, local/remote switch, run & fault lights
- Controller modulates the coil valve to hold room temperature
- Optional RS485 link to the building automation system
- Direct start < 11 kW, star-delta ≥ 11 kW, VFD or soft starter
