Technology Overview
NAllen Holdings’ patented radiant heating platform is engineered for full configurability, delivering 40–200 watts per inch (136.5–682.4 BTU/in²) of targeted thermal energy.
Unlike traditional single‑output heaters, this technology is built as a scalable thermal platform — enabling precise watt‑density selection, controlled thermal profiles, and application‑specific configurations for cementitious assemblies.
Why This Platform Is Different
The Problem We Solve
Construction sites, especially large cementitious assemblies and 3D‑printed concrete, operate inside unpredictable micro‑climates—wind stripping heat, moisture trapped in mass walls, cold substrates delaying coatings, and weather windows that evaporate mid‑shift. Traditional air heaters fight ambient air (and lose). NAllen’s platform solves the surface‑first problem with a short‑wave radiant (SWIR) system that delivers targeted watt density (40–200 W/in) directly into the material, creating localized, stable micro‑environments around the work zone.
What Makes It Unique
-
Patent‑anchored configurability: Our IP covers a 40–200 W/in range, posturing us to tune heat profiles for substrate thickness, moisture load, geometry, and weather—now and for future form factors.
-
Portable, jobsite‑ready architecture: Lift‑mounted or ground‑portable units position the emitter where the work is, not where the outlet happens to be—preserving productivity in tight, windy, or elevated work.
-
Micro‑climate engineering: Fans, hoods, and simple airflow management establish updrafts that keep visible emissions off workers and out of intakes while concentrating energy into the substrate—a controllable micro‑environment at the wall.
-
3D‑printing advantage: Layer‑based deposition demands tight inter‑layer temperature and moisture control. Our platform stabilizes the micro‑climate around lifts, helping bonds form predictably, minimizing shrinkage and rework—even outdoors.
Proven by Independent Testing
-
NCMA ISO/IEC 17025: Short‑duration exposures representative of our field process produced moderate internal temperature rise, no observed surface damage, and ~30 °F max rise at the non‑exposed face; saturated panels lost ~41 lb (18.6 kg) of water in 116 minutes.
-
Retail live‑site IH sampling (Walmart MS & KY, Target OH): Dust, respirable dust, crystalline silica, metals, VOCs, and PNAHs were non‑detect or below OSHA/ACGIH limits across campaigns; residues characterized non‑hazardous (TCLP). (One short‑term worst‑case respirable‑dust reading in Louisville was flagged as a sampling‑setup anomaly.)
Patent‑Based Configurability
Our patented watt‑density range allows systems to be tuned for:
-
Variable substrate thicknesses
-
High‑moisture or slow‑drying materials
-
Large CMU or concrete envelope assemblies
-
Cold‑weather stabilization
-
Accelerated coating workflows
-
Localized microclimate conditions
This adaptability makes the technology a platform, not a fixed‑output device.
307,080 BTU Configuration (Example Implementation)
The widely referenced 307,080 BTU field unit is a single physical configuration of our platform.
It demonstrates what becomes possible when the patent’s watt‑density range is scaled into a full‑size, high‑capacity system.
Because the patent covers the full 40–200 W/in range, future systems can be:
-
Higher or lower watt‑density
-
Shorter, longer, narrow, or wide
-
Modular or multi‑zone
-
Built for specific substrates or environmental conditions
NAllens platform scales with the needs of the project.
Core Capabilities
Our patented radiant heating platform supports:
Substrate Conditioning
Balances moisture and temperature within CMU and concrete assemblies.
Moisture Management
Accelerates the removal of trapped moisture prior to coatings or finish work.
Coating Workflow Optimization
Enhances coating dehydration, curing consistency, and adhesion stability.
Environmental Thermal Control
Creates controlled microclimates around substrates for predictable outcomes.
Rapid Thermal Response
Short‑wave radiant energy delivers immediate, targeted heat with minimal loss.
Micro‑Climate Engineering for Layer‑Based Cementitious Systems
(Including 3D‑Printed Concrete)
3D‑printed concrete depends on rapid, repeated deposition of cementitious layers — each requiring stable thermal conditions to achieve proper bonding and structural performance.
Traditional heating systems introduce air turbulence or uneven heating, disrupting curing and destabilizing moisture profiles.
NAllen Holdings’ radiant platform produces localized, stable micro‑climates that maintain predictable conditions around printed assemblies.
Benefits for 3D‑Printed Structures
-
Uniform reduction of moisture across layers
-
Stable interlayer temperatures for better bond formation
-
Penetrative radiant energy that reaches deeper into extruded material
-
Accelerated, predictable curing cycles
-
Reduced risk of cracking, shrinkage, or delamination
-
Weather‑resilient performance for outdoor or cold‑weather printing
Why the Patent Matters
NAllens patented watt‑density range enables thermal profiles to be matched to:
