Description

Sondex is a professional plate heat exchanger brand under Danfoss (Denmark), specializing in the design and production of high-performance plate heat exchangers and related components. It is one of the well-known manufacturers in the global plate heat exchanger industry.

I. Core Product: Plate Heat Exchangers

Its products are characterized by high heat transfer efficiency and customized design, covering multiple types of heat exchangers:
  • Conventional Gasketed Plate Heat Exchangers:Adopt unique Sonder series components (such as SonderLock fasteners, SonderSnap clips, and Hang-On suspension parts), which fix gaskets without glue for easier installation and maintenance.The plates use Micro Plate™ technology, featuring high heat transfer efficiency and low pressure drop, suitable for HVAC, food & beverage, chemical, and other industries.
  • Semi-Welded / Fully Welded Plate Heat Exchangers:Suitable for high-pressure and corrosive medium working conditions (e.g., chemical, petrochemical industries), with a maximum working pressure of 30bar and a temperature range of -20°C to 180°C.Plates are welded via laser/TIG processes, eliminating gasket leakage risks while retaining partially detachable structures for easy maintenance.
  • Wide-Gap Free-Flow Plate Heat Exchangers:With a plate gap of up to 5mm, they can handle media containing particles or fibers (e.g., slurries in papermaking and sugar industries) and support CIP (Clean-in-Place) online cleaning.
  • Brazed Plate Heat Exchangers:Made via vacuum brazing, they have a compact structure, suitable for refrigeration, heat pumps, oil cooling, etc., with a maximum flow rate of 7200m³/h.

II. Sonder Series Components (Corresponding to Your Provided Models)

Models like "S4A, S16, SW40" are plate/component codes for heat exchangers, corresponding to Sondex’s core technical components:
  • SonderLock: A fastener-based gasket fixing system that locks gaskets in plate grooves via rubber buttons (no glue required), enhancing sealing performance and durability.
  • SonderSnap: Clip-type components that assist plate alignment and prevent "snaking misalignment" during assembly.
  • Hang-On: Suspension systems that ensure long-term stable operation of plate assemblies.
  • Suffixes (e.g., A/B/D): Represent different specifications/versions of the same basic component (e.g., differences in size or material).

III. Application Fields

It covers industries such as HVAC, food & beverage, chemical, petrochemical, marine, papermaking, and sugar production. It is widely used in scenarios requiring high heat transfer efficiency, compact space, or handling of special media.
