Overview
The Hoenle jetCURE LED is a high-intensity, modular linear UV LED curing system engineered for precision photopolymerization in demanding industrial environments—particularly within architectural coatings, concrete additive manufacturing, precast concrete surface treatment, and construction-grade adhesive bonding. Unlike broadband mercury arc lamps, the jetCURE LED employs narrow-band solid-state UV-LED emitters operating at discrete peak wavelengths (365 nm, 385 nm, 395 nm, or 405 nm), each with a spectral bandwidth of ±10 nm. This spectral fidelity enables optimal matching to the absorption profiles of modern photoinitiators used in UV-curable construction materials—including acrylate-based sealants, epoxy-acrylate hybrid coatings, and reactive silane-modified polymers. The system operates on the principle of free-radical or cationic photopolymerization, where photon absorption triggers rapid crosslinking without thermal degradation—critical for temperature-sensitive substrates such as fiber-reinforced cementitious composites or polymer-modified bituminous membranes.
Key Features
- Modular linear emitter design with scalable length options (standard units from 100 mm to 1,200 mm active irradiation zone)
- Dual-wavelength capability: Independent control of two distinct UV bands within a single housing—enabling sequential or simultaneous irradiation for multi-stage curing protocols
- High irradiance output: Up to 12 W/cm² at 10 mm working distance (dependent on wavelength and configuration)
- Thermally stabilized LED architecture with active cooling and real-time junction temperature monitoring to ensure irradiance stability over extended operation cycles
- IP54-rated enclosure suitable for factory-floor deployment in humid, dust-prone environments common in precast concrete plants and dry-mix mortar production facilities
- Integrated analog/digital I/O interface supporting 0–10 V, PWM, and Ethernet/IP for seamless integration into PLC-controlled production lines and Industry 4.0 MES systems
Sample Compatibility & Compliance
The jetCURE LED is validated for use with UV-curable formulations compliant with EN 1504-2 (products for protection and repair of concrete), ASTM D7235 (test method for UV-cured coating adhesion on mineral substrates), and ISO 11998 (resistance to wet abrasion of coatings on building materials). It supports uniform curing of viscous, pigmented, and filler-loaded systems—including calcium carbonate–filled acrylic sealants, silica-fumed epoxy coatings, and UV-reactive polyurethane grouts—without surface wrinkling or subsurface inhibition. All optical components meet EU RoHS 2011/65/EU and REACH Annex XVII requirements. The system’s electrical design conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions), and carries CE marking for machinery safety under Directive 2006/42/EC.
Software & Data Management
The jetCURE LED integrates with Hoenle’s optional CURAControl software suite, which provides traceable process parameter logging—including irradiance profile mapping, cumulative radiant exposure (J/cm²), lamp-on time, and thermal drift compensation data. All operational records are timestamped and exportable in CSV or XML format for quality documentation per ISO 9001:2015 and EN 1504-9 (quality control of repair products). When configured with optional Ethernet connectivity, the system supports audit-trail functionality aligned with FDA 21 CFR Part 11 requirements for electronic records and signatures—making it suitable for GMP-aligned R&D labs developing construction chemical formulations under regulatory oversight.
Applications

- On-line curing of UV-reactive waterproofing membranes during roll-to-roll lamination
- Final cure of UV-activated structural adhesives used in façade anchoring systems
- Rapid pre-cure stabilization of digital inkjet-printed decorative patterns on fiber-cement boards
- Curing of low-VOC, solvent-free encapsulants for embedded sensors in smart building envelopes
- In-process consolidation of UV-crosslinked polymer-modified mortars in automated troweling lines
FAQ
What is the typical service life of the LED modules under continuous industrial operation?
Rated minimum L70 lifetime exceeds 20,000 hours at nominal drive current and maintained junction temperature (<65°C).
Can the jetCURE LED be integrated into existing conveyor-based curing lines?
Yes—standard mounting brackets, adjustable height stands, and configurable cable lengths support retrofitting into conveyors with speeds up to 15 m/min.
Is spectral calibration traceable to national standards?
Each unit ships with a NIST-traceable spectral irradiance certificate issued by PTB Braunschweig (Physikalisch-Technische Bundesanstalt), including full spectral power distribution (SPD) curves.
Does the system support variable intensity zoning along the linear axis?
Not natively—but optional segmented emitter arrays (e.g., three independently addressable zones) are available upon request for graded-cure applications.
Are replacement emitters field-serviceable without specialized tools?
Yes—modular LED bars are designed for tool-free hot-swap replacement with alignment pins ensuring repeatable optical positioning.
