Level Wound Coils(LWC)

Continuous defect-free lengths spooled on robust cardboard cores, formatted for high-speed uncoiling, automatic bending, and fin-block assembly.

Inner Grooved Tubes

Internally micro-ribbed bore geometries engineered to maximize heat transfer coefficients inside high-pressure commercial refrigeration and chiller coils.

Service Packaging

Pancake Copper Coils

Phosphorized deoxidized copper coils coiled in single or dual flat layers, dried and capped for field fabrication and clean fluid routing.

Eddy Current Testing

Specification Access

Automated optical sensors record wall concentricity, outer diameter boundaries, and internal rib geometry down to micron tolerances.

Online defect detection scans full tube lengths under electromagnetic inspection to eliminate microscopic surface fissures before winding.

Procurement engineers download mill schedule sheets, temper certificates, and packaging parameters for instant manufacturing evaluation.

Compliance Benchmarks

Alloy temper and wall concentricity certified to ASTM and EN refrigeration standards.

Every production lot undergoes rigorous chemical analysis, tensile testing, and internal cleanliness verification to withstand demanding eco-refrigerant operating pressures.
