Product Introduction
Far-infrared drying equipment
We focus on drastic reduction of drying cost and development of eco-friendly high-efficiency system,
future-oriented eco-friendly energy, and far-infrared drying equipment.
- Product Introduction
Ortech drying equipment dries the paints after painting or moisture of agricultural and fishery products by far-infrared radiation heat radiated from a far-infrared electric heater installed inside the drying booth without using any oil boiler.

-
-
01
High efficiency
The far-infrared heater drying equipment transfers heat directly to the heated object to be almost 100% in heat efficiency compared to the indirect heating type that heats the air layer in the middle with a heat efficiency of only 30~40% level.
-
02
Low operating cost
Operating cost is low due to high heat efficiency and maintenance is simple and easy.
-
03
Safe
The risk of fire is low because the temperature control is easy relative to hot-air drying by indirect heating. Also, safe thanks to own safety device and sensing device.
-
04
Comfortable to be good for health
Safe because the far-infrared ray, which is not harmful to human body, is used and convection, radiation, and conduction work together, so there is no excessive drying to make the interior space pleasant and comfortable.
-
05
Eco-friendly, no pollution
Not using oil, it is an environment-friendly drying system to have pleasant and comfortable indoor air because it does not emit harmful gases such as CO2 and does not smell.
-
06
Uniform paint and moisture drying
Indirectly heated drying equipment has an inconsistent temperature in the painting booth. Therefore, there is no uniform drying in the automotive paintwork. However, the far-infrared paint drying equipment is of a direct heating type and of a radiation type, so uniform paint drying is available.

Details / Type Hot air drying type (Existing) Far-infrared ray radiation heat type How it works 
The air heated by an oil boiler is infused inside the booth so that its convection around the painted body surface may dry it.
Following the principle of nuclear magnetic resonance using far-infrared radiation heat, self-heating and drying effects simultaneous temperature rise inside and outside the body.Combustion by oil Far-infrared radiation heat is generated using electricity Cost of using for 1 month 2,311,750 KRW (5 hrs/day*25 days)
with unit price: 1,321 KRW/ℓ222,750 KRW (5 hrs/day*25 days)
Electrical expense: 81 KRW/KWHEnvironmental issues Danger of using oil, harmful gas generated when burned Safe in use, no pollution, eco-friendly Quality difference Dust or powdery dust generated by forced circulation and convection makes the surface treatment hard. good painting surface due to generation of radiation heat like a light with no air movement Operational use Breakdown of combustion burner, danger of overheat and fire, stoppage due to no fuel supply, heat loss due to burden of heating the whole booth Operation is simply done by controller. Efficient operation with uniform heating is possible. Future prospect Financial burden due to high oil prices, VOC- and THC-based burden Most suitable for drying water-soluble paints in the hybrid era.
- How drying works
-
In the far infrared drying the heat, as a radiation energy, reaches the heated object in a straight line like a electromagnetic wave while having a little heat loss and the temperature of the organic material rises both inside and outside at the same time to have a high drying efficiency and dry in a shorter time.
