History of Sondex
Sondex was founded in 1984 in Aarhus, Denmark, by Aage Søndergaard Nielsen. From the beginning, the company specialized in designing and manufacturing plate heat exchangers, focusing on customized solutions for industries such as district heating, food and beverage, marine, and industrial processing.
Sondex quickly gained a strong reputation for innovation and high-quality engineering, leading to rapid global expansion. Over the years, the product range was significantly broadened to include brazed, welded, and spiral heat exchangers, as well as freshwater distillers and district heating units. This growth positioned Sondex as a key global player in the heat transfer solutions market, with around 40 subsidiaries and manufacturing facilities worldwide.
In July 2016, Sondex was fully acquired by Danfoss, another Danish company renowned for its expertise in heating and cooling solutions. This acquisition allowed Danfoss to strengthen its position in the heat transfer market by combining its technologies with Sondex’s extensive product line and technical know-how.
Today, SONDEX products are part of the Danfoss portfolio, continuing to deliver innovative, energy-efficient heat exchanger solutions. The legacy of Sondex lives on through Danfoss’s commitment to quality, customization, and customer satisfaction across global industries.
Heat exchangers of the brand
SONDEX offers a wide range of plate heat exchangers designed to meet the needs of various industrial applications. These include:
Brazed Plate Heat Exchangers
Designed for applications involving high temperatures and pressures, brazed plate heat exchangers offer efficient heat transfer in a compact footprint. The plates are permanently brazed together, eliminating the need for gaskets and allowing for high-performance thermal efficiency.
Welded Plate Heat Exchangers
Suitable for demanding environments, welded plate heat exchangers are built to handle aggressive media and extreme operating conditions. The plates are welded together to ensure high mechanical strength and resistance to pressure and temperature.
Gasketed Plate Heat Exchangers
Ideal for applications with moderate temperatures and pressures, these exchangers use replaceable gaskets between the plates, allowing for easy maintenance and cleaning. They provide excellent thermal performance and flexibility in a wide range of industries.
Choosing PHEwtur gaskets
At PHEwtur, we specialize in providing high-quality replacement gaskets for plate heat exchangers. Our products offer exceptional performance at competitive prices, meeting the needs of even the most demanding industrial users.
We understand that gaskets are critical to the efficiency and sealing integrity of a plate heat exchanger. That’s why we offer a wide selection of compatible gaskets for major brands, including SONDEX®, Alfa Laval, Tranter, APV, and many more.
Our gaskets are manufactured to strict quality standards, ensuring performance equal to or better than original parts. We use top-grade materials such as Nitrile (NBR), EPDM, Silicone, and FKM (Viton), which provide excellent resistance to wear, chemicals, and high temperatures.
