The Sun-Spot HT-100 and HT-200 are flameless catalytic infrared heaters, an industrial paint drying and curing system for paint, primer, clear coat and wood finishes. A catalyst pad turns natural gas or propane into medium-wave infrared heat without a flame. The coating absorbs that energy directly, so parts cure in minutes, with less dust and far less wasted energy than a hot-air convection oven. Both models are designed and built by Sun-Spot in Joliette, Québec.
Which model do you need?
- HT-100 (Standard): one heating head on an articulated arm, curing area of about 4 × 4 ft. Best for smaller parts, spot repairs and flexible production.
- HT-200 (Premium): two 20 × 20 in heating pads on a 60 in arm with 180° rotation, curing area up to 4 × 8 ft (1250 × 2450 mm). Best for large panels, doors, cabinets and high-volume lines.
Why choose Sun-Spot
- Fast cure: 2 to 20 minutes for common coatings, up to 4 times faster than hot-air convection.
- Low running cost: under $1 CAD per hour in gas, up to 80% less than convection and up to 60% less than electric short-wave infrared.
- Flameless and clean: no open flame, and the only by-products are carbon dioxide and water vapour, with no CO or NOx.
- Precise control: built-in pyrometer with ±3°F (±1.6°C) accuracy, plus programmable ramp time, cure temperature and cure time.
- Built to last: CSA (Canada and US) and CE approved, with a service life of up to 20 years.
What it cures
Water-based and solvent-based coatings on wood, metal, plastic, fibreglass and composites: lacquers and pre-cat or post-cat wood finishes, kitchen cabinets, doors and windows, automotive primers and clear coats, and industrial polyurethane.
Typical cure times
| Coating | Cure time |
|---|---|
| Automotive water-based coating | 2 min |
| 2K automotive primer | 8 min |
| Wood coating, pre-cat or post-cat | 8 min |
| Automotive clear coat | 15 min |
| Industrial polyurethane | 15 min |
| Polyurethane varnish for wood | 20 min |
Sun-Spot figures. Real cure times depend on the coating, film thickness, substrate and shop conditions.
