Spiral Heat Exchangers Removal for Industrial Refrigeration Facilities

Spiral Heat Exchangers removal context in Industrial Refrigeration

A spiral heat exchanger (SHE) is a highly efficient, compact heat transfer device constructed by rolling two parallel metal plates around a central core to form two separate, concentric spiral channels. Installed removal from a industrial refrigeration plant also depends on the actual process, residual service, isolation status, surrounding systems, and facility access described in the industrial refrigeration evidence record.

The removal plan must be based on the submitted unit and site. This page does not imply a local crew, permit authority, preapproved lift, guaranteed pickup, or unconditional service availability.

Isolation and residual-service record

Before commercial or logistics commitments, document how both exchanger sides were isolated, drained, cleaned, released, and separated from the industrial refrigeration system. Unknown conditions should be identified as unknown.

• Verify the type of refrigerant used (e.g., anhydrous ammonia, CO2, or synthetic) via equipment nameplates and system documentation.
• Check for maintenance logs and Process Hazard Analysis (PHA) records, especially for ammonia systems subject to OSHA and EPA regulations.
• Inspect the condition of compressors, heat exchangers (shell-and-tube or plate), and piping for signs of corrosion, wear, or component fatigue.
• Ensure complete isolation, depressurization, and draining of both hot and cold fluid circuits before disconnection.
• residual viscous fluids, slurries, or solids may remain trapped in the spiral channels and require specialized flushing or handling.
• rig securely using manufacturer-designated lifting lugs or structural frame points, accounting for the heavy, dense nature of the coiled metal construction.

Dismantling, loading, and freight planning

The physical plan should connect the spiral heat exchangers configuration to verified dimensions, weight, lifting points, access, staging, carrier profile, and responsibility boundaries.

• Ensure complete isolation, depressurization, and draining of both hot and cold fluid circuits before disconnection.
• residual viscous fluids, slurries, or solids may remain trapped in the spiral channels and require specialized flushing or handling.
• rig securely using manufacturer-designated lifting lugs or structural frame points, accounting for the heavy, dense nature of the coiled metal construction.
• protect flanged connections and machined cover sealing surfaces from mechanical damage during transit.
• Decommissioning requires specialized procedures to safely evacuate and recover refrigerants, particularly hazardous substances like anhydrous ammonia, to prevent dangerous releases.
• Piping and components must be carefully isolated and purged to avoid trapped liquid or sudden pressure releases that could cause hydraulic shock or component failure.
• Heavy lifting equipment is necessary to remove large compressors, condenser units, and heat exchanger vessels from the facility.

Written scope before work

Dismantling, rigging, loading, freight, scheduling, and payment are conditional project functions. A written scope must identify responsible parties, safety release, access rules, exclusions, equipment boundaries, carrier requirements, and commercial terms before performance.
