HEXNOVAS independently manufactures welded plate-and-block heat exchangers for Compabloc-type duties, including process heat recovery, condensation, reboiling and replacement projects. These are HEXNOVAS-engineered units, not Alfa Laval original products.
Laser-welded corrugated plates form a rigid rectangular plate pack inside a bolted steel shell. The two media flow through alternating crossed or counter-current channels, and removable side covers provide direct access to each channel group.

Engineering explained
See what is happening inside the exchanger.
Product imagery is paired with technical context so buyers and engineers can understand construction, flow path and configuration—not just the exterior.
01
Accessible welded block construction
The exploded view identifies the fully welded plate pack, removable side sheets, headers, seals, girders and support feet.
02
Cross-flow welded channels
The two media pass through separate welded corrugated channels in cross-flow.
03
Baffled multi-pass arrangement
Internal baffles reverse the flow direction to create the required multi-pass pattern.
04
Condenser and reboiler duties
Dedicated arrangements manage vapour, non-condensable gas, condensate and liquid paths for phase-change service.

Review a Compabloc duty with HEXNOVAS FW-PB
Compabloc is an Alfa Laval product name. HEXNOVAS FW-PB is our own plate-and-block series, not an Alfa Laval original product. For a replacement review, send the original model, nameplate, general arrangement (GA) drawing, media, flow rates, inlet/outlet temperatures, operating and design pressures, allowable pressure drop, connection sizes and installation space. Similar duty or nominal size does not establish dimensional, thermal or mechanical interchangeability.
For replacement assessment, provide the original model, nameplate, GA drawing, media, flow rates, inlet/outlet temperatures, operating and design pressures, allowable pressure drop, connection sizes and installation space. Confirm materials, pass arrangement and cleaning access. Performance, dimensions and mechanical fit require project-specific verification.
Frequently asked questions
Key questions before product selection.
How does a Compabloc-type heat exchanger work?
A fully welded corrugated plate pack creates separate hot and cold channels. The media pass through crossed or multi-pass flow paths, while removable side covers provide access for inspection, cleaning and maintenance.
Does HEXNOVAS manufacture the original Alfa Laval Compabloc product?
No. HEXNOVAS manufactures its own welded plate-and-block heat exchangers for Compabloc-type duties. Each unit is selected and engineered by HEXNOVAS; it is not an Alfa Laval original product.
What information is needed for a Compabloc replacement or alternative?
Provide both-side fluids, flow rates, inlet and outlet temperatures, allowable pressure drop, design pressure and temperature, fouling risk, material requirements, nozzle drawings and installation dimensions. Thermal performance and mechanical fit are confirmed for each project.
Can a Compabloc-type heat exchanger be mechanically cleaned?
Yes. The welded plate pack remains sealed, while removable side covers can provide direct access to the channel groups for inspection, mechanical cleaning or clean-in-place procedures.
Can Compabloc-type units handle high temperature or pressure?
Standard and engineered pressure-temperature envelopes depend on the model, plate material, cover design, seals and applicable code. HEXNOVAS confirms the allowable limits against the complete operating and design conditions.
