Sheet Metal Workshop
CNC laser cutting, turret punching, and robotic bending maintain housing dimensions within plus-minus 0.1mm tolerances.
Core Production Lines
In-house polymer membrane and aluminum enthalpy core manufacturing ensures airtight lamination and zero cross-contamination between airstreams.
Assembly and Testing
Two automated production lines use computerized wind tunnel test rigs to check airflow, pressure, and electrical safety on every batch.
OEM Customization
Custom cabinet dimensions, controller firmware integration, private label silk-screening, and export-grade packaging.
Incoming Material Inspection: Raw steel thickness and electronic component stability are checked using spectral analysis and digital calipers.
Aero-Acoustic Testing: Air performance is tested according to AMCA standards to verify actual CFM output against static pressure curves.
Electrical Safety Checks: Dielectric withstand testing, grounding continuity checks, and leakage current analysis are run on 100 percent of finished units.
Structural Design
Adjustable casing thickness, flexible duct collar positions (top, side, or end entry), and ultra-slim ceiling layouts.
Control Systems
Support for standard 0-10V analog signals, Modbus RTU communication protocols for building management systems (BMS), and custom Wi-Fi app interfaces.
Component Selection
Options for specialized EC backward-curved centrifugal fans, custom filtration stages (HEPA H13 or activated carbon), and automated defrost modules.
Calculate Required Airflow
Determine air volume using local building regulations or room occupancy rates to choose the correct CFM rating.
Evaluate Static Pressure
Add up resistance from duct lengths, bends, distribution boxes, and diffusers to ensure the fan maintains airflow under pressure.
Choose Core Material
Select polymer enthalpy cores for heat and humidity recovery in humid climates, or aluminum sensible cores for dry industrial applications.
Determine Acoustic Limits
Match sound pressure level limits with installation locations, such as ceilings near bedrooms or dedicated utility rooms.
