Thermal Break vs Non-Thermal Break
Parameters
Thermal Break
Non-Thermal Break
Construction
Aluminium outer shell + nylon insert separating inner and outer faces
Single-material aluminium extrusion
Heat Transfer
Nylon insert prevents heat conducting across the structural profile frame
Heat conducts freely across the structural metal frame
Condensation Risk
Significantly Reduced
Higher Proneness Risk
EN 1886:2007
Supports structural classification standards
Not applicable across parameters
Primary Use Case
Energy-rated, cleanroom, healthcare, and pharmaceutical AHU variants
Standard commercial layout AHUs
Profile System Logic
Each series is a matched set of four fundamental components — interface geometry tolerances are engineered collectively to eliminate leakage paths.

Structural Profile Variants
Engineered profiles developed for specific functional application demands across specialized installation configurations.
Variant Classification
Functional Scope & Operation
Section Joining
Interlocks two separate sub-frame chassis modules seamlessly into a single line array during field site installation deployment.
Inner Open Door
Integrates a flush access door perimeter framing seat natively into the system framework panel configuration layout.
Snap Fix
Secures enclosure wall sheeting panels via mechanical snap clamping blocks, removing internal protrusion rivet heads.
Serration Surface
Features high-density microscopic surface grooving patterns to increase liquid thermal adhesive bite thresholds.
Clean Room
Ensures smooth, zero-crevice transitions across profiles to prevent microbial dust particle containment pockets.
Hygiene Standard Compliance
VDI 6022 Standard
Classification Scope
The primary European/German governing baseline metric setting structural requirements for structural hygiene parameters within central ventilation systems.
Material Imperative
Demands internal structural surfaces completely resist microbial culture growth, fungal tracking propagation, and toxic volatile chemical off-gassing.
Component Integration
Compliant Hardware Group
All injection-molded composite accessories — corner joiners, drive gearings, outer operating handles, structural hinge components, and inner casing seals.
Critical Environments
Essential for modular handling assemblies targeted at hospitals, biopharma production sites, chemical research cleanrooms, and food facilities.
VCD Mechanics
Volume Control Damper Mechanics
Mechanical operational breakdown of the custom volume control damper system logic components and dynamic balancing paths.
Damper System Component
Mechanical Role & Application Performance
Base Profile (AL DMTB)
Acts as the rigid outer frame channel securely mounted within structural ventilation or duct connection openings.
Shoulder Profile (AL DMSH)
Spans internal structural channel dimensions to anchor blade pivot bearing points in true linear horizontal alignment.
Blade Profile (AL DMBL)
The main airfoil component that rotates on its axis to accurately modulate or isolate airflow volume rates.
Gear Wheel (NY DMGR)
Translates external handle rotational torque into opposing interlocking blade movement tracking paths.
H-Bush Bearings (NY DMHB)
Provides a low-friction pivot bearing configuration surface to prevent rotational sticking over prolonged exposure cycles.
Blade Plates LH/RH (NY DMPL / R)
Clamps structural blade terminal end profile sections to block lateral air slice blow-by gaps.
Stopper Stick (NY DMST)
Establishes mechanical travel boundaries at exactly 0° and 90° reference points to prevent over-rotation.
Intermediate Profile (AL DMIM)
Reinforces wider industrial damper spans to eliminate high-pressure central structural bowing deflections.
