05 — Copper parts

Everything between the coil and the compressor

Small parts that stop a shipment: strainers, accumulators, valves, flare fittings and brazed copper assemblies, packed with the coils.

Accessories
Copper fittings, valves, filters and accumulators

Copper fittings & refrigeration accessories

We consolidate the small hardware with the main equipment so your installation team receives one complete kit instead of three separate deliveries.

  • Filter driers
  • Accumulators
  • Schrader valves
  • Flare fittings
  • Sight glasses
  • Brazed assemblies
  • Capillary tubes
  • Mounting brackets

06 — OEM & custom

Built to your drawing, packed under your brand

Send a drawing, a sample or a performance target. We quote the coil geometry, the motor match and the packaging as one programme.

Custom
Custom manufacturing and export consolidation

Custom coils, private label, mixed containers

Our tooling is developed in-house, so a new fin pattern or casing does not wait for an outside mould shop. Typical custom work:

  • Drawing-based coils
  • Custom fin pitch
  • Private-label cartons
  • Your model codes
  • Sample before batch
  • Mixed-product containers

Not sure which model?

Send us the application — we will size it.

Tell us the cabinet volume, the target temperature and the refrigerant. We will come back with the compressor, the coil and the motor that match.
