Product Overview
The V Series is Solar Products’ fastest heater — V-shaped stamped elements permanently bonded to a high-temperature insulation board, a low-mass emitter that heats up and cools down fast. Element temperatures run to 2100°F with a 2-micron peak wavelength, so its power density and response rival short-wave heaters while it keeps the durability of a medium-wave package — at watt densities up to 100 watts/in², the highest in the Solar Products line. That combination suits fast drying of water and solvent, heating plastics and glass, and processing heat-sensitive coated webs and textiles. Sizes are custom-configured to the application. Solar Products is the Aspeq Infrared Division — an industrial infrared process-heating manufacturer, not a solar-energy company.

Key Features & Benefits
- Energy lands on the product, not the air — radiant infrared sends heat straight to the workpiece, so the part absorbs it directly while the surrounding air stays comparatively cool — faster heat-up, energy concentrated where it counts, and output that drops almost the moment you turn the panel down. The right tool when you are heating a defined surface or web, not a roomful of air.
- Medium-wave output most materials readily absorb — the emitter works in the medium-wave band, which is well matched to plastics, coatings, paints, and organic materials — the energy is absorbed at the surface and converted to heat rather than passing through or reflecting away. Match the wavelength to the material and the heating is fast and efficient; the wrong band wastes energy on the air.
- Built to your drawing, not pulled off a shelf — every panel is made to order — dimensions, wattage, watt density, emitter type, and mounting are specified per job and arranged to the oven zone or fixture, which is why these go into OEM machinery and process lines rather than a catalog. The panel fits the process, not the other way round.
- Proportional zone control comes with the panels — fast radiant response pairs naturally with SCR / PID control, and Solar Products supplies the matched zone controls and tuning, so the heat profile can be trimmed across the oven width and length. The control scheme is built to the panel layout, not bolted on after.
- Drops into — or re-optimizes — an existing oven — because the panels are built to drawing, a replacement can match the dimensions, wattage, wavelength, and mounting of the panels it replaces, or be re-specified if the original was the wrong wavelength or watt density for the substrate. A retrofit is a chance to fix the original spec, not just swap a failed panel.
Specifications
- Operating principle
- Electric radiant infrared heating — an electric resistance element heats an emitter face (or tube) that radiates medium-wave infrared energy directly onto the workpiece or web, rather than warming the air the way a convection oven does. The energy lands on the product surface, so drying, curing, laminating, thermoforming, and preheating run faster and under tighter control.
- Emitter / face construction
- V-shaped stamped elements permanently bonded to a high-temperature insulation board — a low-mass emitter construction built for fast heat-up and cool-down.
- Wavelength band
- Element temperatures up to 2100°F with a 2-micron peak wavelength — short-wave-like output character in a durable medium-wave package.
- Watt density
- Up to 100 watts/in² — the highest watt density in the Solar Products line.
- Emitter / face temperature
- Element temperatures up to 2100°F.
- Panel / element dimensions
- Sizes are custom-configured to the application and built to drawing.
- Response time
- Fast — the low-mass stamped elements heat up and cool down quickly, with power density and response rivaling short-wave heaters.
- Life expectancy
- 12,000+ hours, temperature-dependent.
- Voltage / phase
- Built for any commercial or industrial supply voltage — 120, 208, 220, 230, 240, 277, 380, 415, 460, 480, 575, and 600 V, single- or three-phase, with dual- or triple-voltage configurations available. The voltage and phase are set with the order.
- Control method
- Medium-wave panels respond quickly, which suits proportional control: an SCR power controller proportioning each zone, a PID loop reading panel or product temperature, and multiple independently controlled zones to tune the heat profile across the oven. Solar Products supplies integrated SCR zone controls and PID tuning with the panels.
- Options & accessories
- Configurable to the application — back-mounted fans, multi-zone heaters, a pyrometer view port through the heater, a replaceable type-K thermocouple, cool-down / drying air holes, parallelogram modules for zoning across wide webs, stainless-steel or no housing (heater board only), wire leads, an electrical junction box, and ¼-20 mounting studs. Specified per drawing.
- Material & process match
- The stamped-element V is the pick where you want fast, short-wave-like response — drying water or solvent, heating plastics and glass, and processing heat-sensitive coated webs and textiles — in a durable medium-wave heater. Use the input form to tell us the substrate, process temperature, and line speed and the construction follows.
- Build & lead time
- Custom build-to-order — virtually every panel is built to the application (dimensions, wattage, wavelength, watt density, emitter type, and mounting). No published price list; pricing is quote-only. Lead times typically run about 3 to 14 weeks depending on configuration.
Common Applications
- Thermoforming oven top and bottom heating zones
- Paint, powder-coating, and e-coat curing ovens
- Screen-print curing and high-speed drying lines
- Glass tempering, bending, and annealing furnace banks
- Semiconductor and electronics process heating
- Automotive fiberglass and composite curing
The common thread is a part or web that passes in front of the panel and absorbs the radiant energy directly. A slow convection oven heating a surface is often a candidate for IR; for heating a large enclosed volume of air uniformly, convection still suits better. Use the input form to send the target material, process temperature, line speed, and area, and the series, watt density, and panel layout are specified from there.
Design & Selection Considerations
- Match the wavelength to the material — not the other way round — materials absorb some wavelengths far better than others; the medium-wave band suits most plastics, paints, coatings, and organics, but the substrate is what should drive the emitter choice. Use the input form to tell us the material and the series and emitter follow. The wrong wavelength heats the air and the oven instead of the part.
- Watt density is bounded by what the substrate can take — a higher watt density heats faster but can scorch a heat-sensitive web or coating; the safe density is set by the substrate and the line speed, not by the maximum the panel can deliver. Size the density to the product, then pick the series that reaches it.
- Standoff distance and reflective / convective losses size the system — the wattage to reach temperature at the required line speed, the panel footprint that matches the oven zone, the standoff from panel to product, and the number of zones all factor into the layout. Use the input form to give us the target material, the process temperature, and the line speed and the panel count, wattage, and layout follow.
- Run the panel at its rating — over-firing is the main life-limiter — kept within design conditions an emitter lasts for years; the common early-failure causes are running hotter than rated, mechanical damage to the emitter face, contamination or overspray baking on, and thermal-cycling stress at the connections. A panel that fails early is usually run above its rating or is the wrong construction for the duty.
- Read the right temperature — panel or product — a PID loop can hold panel temperature or product temperature, and the two behave very differently on a moving web; decide which you are controlling before you pick the control points and zone count. Use the input form to tell us how many zones and whether you read panel or product temperature, and the scheme is built to match.
To spec the right Solar Products V Series stamped-element panel:
Solar Products panels are custom build-to-order, so the quote is only as good as the application data. To spec and price the right panel, have ready: the target material (substrate type and thickness), the process temperature and required line speed or dwell time, the oven zone dimensions and standoff distance, the number of control zones, and the available voltage and phase. The more complete the data up front, the faster and tighter the quote.
