Chilled Water Coils

Copper tube / aluminium fin chilled water coils engineered for AHUs, FCUs and central HVAC systems. Staggered tube layout and corrugated fins maximise heat transfer at low air-side pressure drop.

  • Tube OD: 3/8" or 1/2"
  • Fin spacing: 5.5 – 12 FPI
  • Hydraulically expanded tubes
  • Galvanised / SS casing

DX (Direct Expansion) Coils

Custom DX coils with engineered distributor circuiting for uniform refrigerant flow. Compatible with R-410A, R-407C, R-22 and R-32. Built for OEM split and packaged unit applications.

  • Multi-circuit refrigerant distributor
  • Brazed copper headers
  • Mechanically / hydraulically expanded
  • Custom face area to order

Air Cooled Condenser Coils

Air-cooled condenser coils designed for high ambient Indian conditions. Available in single bank, V-bank and W-bank configurations with corrosion-resistant fin coatings on request.

  • Single / V / W-bank construction
  • Pre-coated hydrophilic fins (optional)
  • High ambient duty design
  • Custom header and connections

Evaporator Coils

Wide-fin evaporator coils for refrigeration and cold-room duty. Generous fin spacing prevents frost blockage and allows easy defrost cycles.

  • Fin spacing tuned for frost duty
  • Electric / hot gas defrost ready
  • Drain pan & casing options
  • Low / medium temperature designs

Hot Water & SS 304 Coils

Hot water heating coils for AHU pre-heat and re-heat sections. SS 304 tube construction available for corrosive or hygienic environments.

  • Copper or SS 304 tubes
  • Working pressure up to 16 bar
  • Single / multi-row designs
  • Pharma & food grade options

Steam Coils

Heavy-duty steam coils engineered for industrial drying ovens, AHU heating and process applications. Designed to handle thermal shock and high steam pressures.

  • SS 304 / copper construction
  • High pressure steam compatible
  • Thermal-shock tolerant design
  • Custom flanged connections
