Barriquand Group

Plates and gaskets heat exchangers are made up of a series of corrugated plates that follow profiles which form, after assembly, the circulation channels for the fluids. Thanks to their shape, the gaskets insure the peripheral sealing of each plate and authorize or prohibit the fluid flow between the plates.
Plates and gaskets heat exchangers are used for different processes: heating / cooling of evaporation fluids, condensation….

Advantages

• Evolutionary countercurrent heat exchangers
• Minimal pressure drop, high turbulence, very high heat transfer coefficient
• Easily openable and cleanable on both circuits
• Joints are clipped or glued according to model
• Options: double-walled plates, wide gap plates…
• Easy to install

Technical Characteristics

• An extensive range
• Up to 45 plate sizes with 3 different angles (including wide gap plates)
• Single-stream exchangers in most cases

Technical Solution

• Flange diameters from 32 mm to 500 mm (1"1/4 to 20")
• Design pressure up to 25 bar (362 psi)
• Lateral flow distribution
• Automatic centering between plates
• Clipped or bonded gaskets (or fixed with gasket glue)
• Deeper gasket grooves
• Flush-fitting gaskets
• Highly resistant gaskets

Materials Of Construction

The brazed plate heat exchanger is used on DHW applications, refrigeration (evaporation/condensation), substations and small and medium-sized district heating installations.

Advantages

The Platular® fully welded plate heat exchanger’s thermal performance and minimal temperature approach is particularly suitable for exchanges on difficult, viscous fluids or fluids charged with suspended materials, but also for the condensation of vapor under vacuum (steam, C.O.V...). Thanks to the multi-pass design possibilities on each circuit, the Platular® is also well suited for lengthy exchanges.

Advantages

• Exclusive patented technology
• Custom manufacturing in France
• For viscous and / or difficult fluids
• Fully visitable and openable, easy to maintain

The Platular® is a compact heat exchanger that brings many advantages in terms of the volume of treated fluids and space required for installation. BARRIQUAND has developed 5 types of exchange stream with different geometrical characteristics offering complementary thermal and hydraulic performance levels and enabling a low thermal approach and minimum pressure drop.

• Technical characteristics
• Complex process fluid (with extraneous matter or viscous) on B channel
• Utility or process fluid on A channel
• Versatile wide gap of B channel (optimized pressure drop)
• Perfect for a long transfer programme with low temperature approach
• Multi-stream design on A channel available
• Easy and fast access for cleaning of the process side
