Quartz Heaters – Precision Infrared Heating

Quartz Sheath
The quartz tube shields the heating coil from ambient heat loss caused by external drafts. It offers the highest infrared transmission of any available material, delivering efficient and uniform heat. More durable than tungsten filament lamps or sealed quartz tubes, quartz heaters provide a long service life—often lasting several years—while producing very low visible light for reduced glare.

Heating Coil
The optimally designed coil ensures uniform heat distribution and emits a clear red glow at full rated voltage. Operating in the infrared medium wavelength range (2.30–3.00 microns), it delivers fast and efficient heat transfer. Fast-acting designs are available when rapid heating is required. Coils are designed for horizontal operation only.

Ceramic Caps
Specially engineered ventilated ceramic caps allow the heater to “breathe” during heating and cooling cycles. These caps also provide mechanical support for the heater and are available in multiple configurations to suit different termination styles.

Terminals
Standard configuration includes a 10-32 stainless steel screw terminal. Additional termination options are available, including lead wires, quick disconnects, and custom styles to meet application requirements.

High-Temperature Cement
A low-expansion, high-temperature cement bonds the quartz tube to the ceramic caps, ensuring durability and thermal stability. Cement-free designs are also available using alternate support methods.

Features

All hot materials radiate energy. Energy is transferred in line of sight by electromagnetic waves, emitted by the source (hot surface) and absorbed by the sink, i.e. the cooler surface. The amount of radiant energy transferred depends on temperature, emissivity and the effective surface area of the source and sink.

Heaters, which utilize radiant energy to transfer heat, are commonly known as infrared radiant heaters. Radiant energy is absorbed into the surface layer of material being heated and then dispersed through the material by conduction. Before you dry, heat, bake or cure any product with any heat source check Akinsun quartz heater features.

Fast Response & Efficient Heat

Standard quartz heaters have a response time of 80% within 15 seconds and 100% within 30 seconds with almost the same cooling time. These heaters are quiet, cool and emit no significant glare. Infrared heat waves are absorbed by both light and dark color surfaces at the same speed. Special heaters can be designed for response times quicker than 15 seconds.

Clean Heat Energy

Akinsun radiant heaters are highly resistant to corrosion, since the heat source is quartz glass. Hardware is made of stainless steel and rust resistant material. An occasional wipe with a cloth keeps it clean.

Mounting Ease and Compact

The termination on our quartz heater are built such that it is easy to hang, easy to detach and hang in new ways. They are compact, so you do not need much room to move around, to make new layouts. The units are very light which makes mounting easy.

Economy and Conservation of Energy

Quartz heaters emit infrared energy, the energy that is most easily absorbed by a mass and converted to heat. The energy goes directly into your product. It does not have to heat a lot of air at first. We use clear (transparent) tubes and also can supply translucent if needed.
Akinsun heaters are up to 80% efficient. Some heat sources return as little as 30% of your input energy in the form of finished work. Because quartz heaters are so efficient you need fewer units, and less floor space to do a job. All which usually equal the cost of the heater in a year's time.
