HINO-TEC List of Products and Services

The heat exchanger of the Oil Heaters A adopts a cross-wave method, achieving high efficiency. It is compact yet secures a heat transfer area of over 5m². Warm air at approximately 40°C blows out from the ducts installed in the oil heaters in two directions. By directing the ducts to areas where the temperature is less likely to rise inside the house, temperature unevenness is improved. 【Features】 ○ More than 20% fuel reduction possible ○ Improvement of temperature unevenness ○ Stainless steel body with excellent corrosion resistance ○ Easy maintenance For more details, please contact us or download the catalog.

• Heat exchanger

At HINO-TEC, we offer a "fin tube type heat exchanger" in the form of a hot water generator (air cooler) and a steam air preheater. The hot water generator (air cooler) is a heat exchanger designed to extract hot water at approximately 60°C to 90°C using gas-liquid type, with heated air or exhaust gas as the heat source. The steam air preheater is a heat exchanger that heats air or exhaust gas using steam as the heat source, and it can utilize superheated, high, medium, or low-pressure steam. 【Features】 ○ Compact design using fin tubes (large surface area per unit area) in the heat transfer tubes ○ Fin tubes are particularly effective when there is a large difference in the film coefficient between the two fluids (hot water generator) For more details, please contact us or download the catalog.

• Heat exchanger

HINO-TEC's "superheated steam heat exchanger" consists of a gas reheater, combustion air preheater, and white smoke prevention air preheater. It is used in waste incineration facilities, industrial waste treatment facilities, and mining and industrial furnaces. 【Features】 ○ Gas Reheater → A device that reduces corrosion of downstream equipment and prevents the generation of white smoke. ○ Combustion Air Preheater → A device that reduces fuel consumption. ○ White Smoke Prevention Air Preheater → A device that prevents moisture in the gases discharged from the chimney from turning into white smoke in the atmosphere.

• Heat exchanger

The "Dust Adhesion Prevention Device for Square Tube Type Heat Exchangers" is a device designed to remove and prevent dust (particulate matter) from adhering inside the tubes of tube-type heat exchangers. Its primary purpose is to prevent adhesion rather than removal. 【Features】 - There are over 100 delivery records in combination with square tube type heat exchangers. - Patent obtained: Patent No. 3326596. For more details, please contact us or download the catalog.

• Heat exchanger

The "square tube type heat exchanger (corrugated tube)" has a high internal boundary layer coefficient due to the spiral groove processing (corrugation) of smooth pipes (bare tubes), allowing for a reduction in the heat transfer area. The fluid flows in a swirling motion, making it difficult for dust to adhere, and it is also excellent for weight reduction. 【Features】 ○ The high internal boundary layer coefficient allows for higher wall temperatures of the heat transfer tubes compared to smooth pipes. ○ Effective against low-temperature corrosion. ○ In cases with a lot of dust, maintenance can be reduced by installing a dust adhesion prevention device.

• Heat exchanger

HINO-TEC's plate heat exchangers consist of two metal plates pressed into a cross-wave shape and seam-welded together to form a set. These sets are combined in groups ranging from several to hundreds and housed within an outer frame via expansion joints at both ends, creating a direct flow and counterflow heat exchanger that prevents mixing of the two fluids. Due to the cross-wave structure, a high heat transfer rate can be achieved, allowing for a reduction in heat transfer surface area, resulting in a more compact design compared to conventional plate heat exchangers. 【Features】 ○ No leaks due to the welded structure ○ Made of heat-resistant steel ○ Elements are wave-shaped curved plates ○ Capable of withstanding thermal expansion differences For more details, please contact us or download the catalog.
