01
No interplate gaskets
Welded heat-transfer channels remove interplate elastomer gaskets. Removable covers still use panel seals selected for the service.
WELDED BLOCK MANUFACTURING · COMPABLOC REPLACEMENT
Welded Block Heat Exchangers for Demanding Industrial Applications
Fully welded plate heat exchangers with no interplate gaskets, engineered for chemical, petrochemical, refinery, oil & gas and high-temperature process duties.

WHY WELDED BLOCK
Why choose a welded block heat exchanger?
Compare the construction against your process duty, available space and maintenance requirements.
02
Compact footprint
A corrugated plate pack concentrates heat-transfer area in a compact block. Compare the complete installed envelope, including maintenance clearance.
03
Mechanical cleaning access
Removable side panels expose the channel groups for inspection and suitable mechanical cleaning. The welded core remains intact.
04
Temperature and pressure capability
Assess welded construction where plate gaskets limit the duty. Confirm design pressure, temperature, materials and code together for the selected unit.
05
Corrosion-resistant alloy options
Select the plate alloy and panel seals against the actual fluid composition, concentration and temperature. Alloy availability alone does not establish suitability.
06
Condensation and evaporation
Channel arrangement can be engineered for phase-change duties, with vapour distribution, drainage and allowable pressure drop included in selection.
07
Retrofit and replacement
Assess a replacement solution for existing Compabloc installations, from the welded plate pack to the complete unit. Mechanical fit and thermal performance require project review.
Shell & tube
Assess available space, fouling behaviour and maintenance access before changing exchanger technology.
Gasketed PHE
Consider welded channels where operating temperature or fluid compatibility limits interplate gaskets.
Existing Compabloc
Start with the existing datasheet and casing condition to decide between plate-pack and complete-unit replacement.
REPLACEMENT SOLUTIONS
Replace the core. Or the complete unit.
Replacement solutions for existing Alfa Laval Compabloc and GEA / Kelvion K°Bloc installations, subject to engineering review.
Compabloc core / plate pack replacement
Review the welded core, plate pattern, materials, baffles and interfaces with the existing casing. Retained components require inspection.
Request replacement assessment ↗Compabloc complete-unit replacement
Assess a complete exchanger against the thermal duty, design conditions, nozzle arrangement, supports and available service space.
Request replacement assessment ↗GEA / Kelvion K°Bloc unit replacement
Evaluate a complete-unit alternative for the existing installation. K°Bloc core interchange is not offered.
Request replacement assessment ↗Send the nameplate, datasheet, general arrangement drawing and operating conditions. Compatibility is confirmed for each project; model numbers alone do not establish a direct fit.

DESIGN THAT WORKS
Performance meets practicality.
A compact process solution
Bring heating, cooling and heat recovery into a compact equipment layout. Selection starts with your thermal duty and available space.
Precision in the plate pack
Automatic laser welding and butt-joint construction are part of PANSTAR’s documented welded-product manufacturing process.
Designed for maintenance
Mechanical cleaning access and accessible welds help make inspection and maintenance part of the equipment lifecycle.
