DexThermic je toplotni izmenjevalnik umazanega zraka (DAHX)® z edinstveno zasnovo, razvit iz nič z uporabo najsodobnejših tehnik računalniškega modeliranja, analitičnih metod, eksperimentalne validacije in inženirskih proizvodnih tehnik.
Izziv, poglobljen, znanstveni postopek za izdelavo enostavnega komercialnega toplotnega izmenjevalnika, ki čisto preprosto, dela tako trdo kot ti.
Ustvarjen za vgradnjo v sisteme kontaminiranega odvodnega zraka, DexThermic rekuperira odpadno toploto iz procesov, kjer se običajne metode rekuperacije toplote pokvarijo in so nagnjene k odpovedi.
Razvito, optimizirano in potrjeno s strogimi raziskovalnimi in razvojnimi potmi za ustvarjanje najbolj praktične in učinkovite zasnove.
Zasnovan tako, da se nahaja v sistemu za odsesavanje onesnaženega zraka, plošča z rebri tekočine poenostavlja toplotno pot med zrakom in tekočino za rekuperacijo toplote, hkrati pa ohranja visoke stopnje rekuperacije toplote in zmanjšuje fizične ovire v zračnem toku.
DexThermic je mogoče konfigurirati za integracijo z Sistem DexTherm za maksimalne rezultate.
Šest let v razvoju. Izdelek obsežnega raziskovalnega projekta UKRI.
Lahko se kombinira v različne konfiguracije, ki ustrezajo vašim potrebam.
Naša brezkompromisna zavezanost kakovosti zagotavlja dolgo življenjsko dobo in zanesljivost.

The design of a Tube Coil Heat Exchanger transfers heat between the air and fluid via the wall of the tubes. The fluid flows through a series of tubes, while the air passes over the tubes, transferring heat energy to the fluid.
This design has a simple thermal resistance pathway, where the resistance is determined by the tube material’s thermal conductivity, the thickness of the tube wall, and the heat transfer coefficient between the fluid inside the tubes and the surrounding air. This offers several advantages, including simplicity, ease of manufacture and cost- effectiveness.
Using a simple flow regime with non-turbulent flows has several disadvantages. One of which is that it results in low heat transfer coefficients for both air and fluid flows. To compensate for this, more tubes can be added, and flow rates can be increased, but this can lead to reduced fouling resistance, increased pressure drop, and increased specific fan power requirements.
The Finned Tube Coil Heat Exchanger was initially created to enhance the performance of the Tube Coil Heat Exchanger through the introduction of extended surfaces (Fins). As a result, this design employs a more intricate thermal resistance network.
The presence of extended surfaces (fins) increases the heat transfer area and alters the air flow patterns, resulting in a more complex thermal resistance pathway. More complex external flow regimes create turbulence and higher heat transfer coefficients for the air flow pathway. This, combined with the increased surface area, results in improved thermal performance and a reduction in overall tube lengths and fluid pressure drop.
The increased surface area and complexity of the thermal resistance pathway in a heat exchanger result in a higher potential for fouling, air side pressure drop, and increased specific fan power requirements.
Our innovative solution combines the best of Tube Coil and Fin Tube Coil designs to deliver an application-specific product that actively resists fouling.
The system facilitates efficient heat exchange between air and fluid by utilising a simple thermal resistance pathway, which enhances high heat transfer coefficients between the fluid enclosed within the Fin-Panels and the surrounding air. The fluid and air circulate through a complicated network of internal and external passages, consistently altering direction and generating turbulence. This design improves fouling resistance, reduces pressure drop, and lowers specific fan power requirements.
For Dext, the disadvantage of this design was that it required us to go back to the drawing board and carry out extensive, in-depth research & development, testing, and validation; requiring significant investment and several years of hard work. The result was exceptional though, thanks to Dext’s determination and the support of a UKRI research projecti.
This new Fin-Panel technology has the potential to revolutionize the field.
Prenovili smo toplotni izmenjevalec rebra in cevi, tako da smo odstranili cevi in omogočili rebrom, da prenašajo tekočino za prenos toplote. Pri tradicionalnih sistemih plavuti in cevi se delci, ki prehajajo skozi sistem, sčasoma upočasnijo in zamašijo. Niz FFP to obravnava z zmanjšanjem poti odpornosti na delce na zračni strani in uvedbo tehnično naprednih površin za prenos toplote na strani zraka in tekočine.
