ACR Tubes

ACR Tubes

Inner Grooved Tubes

We produce a specialised air-conditioning and refrigeration tube with an enhanced inner surface for superior heat transfer performance. The surface enhancement can be varied according to the application and we can control the weight and the dimensions of the tube with very close tolerances.

Applications for Inner grooved ACR Tubes

  • Air-conditioning (residential and commercial)
  • Refrigeration (commercial and transport)
  • Heat-exchanger manufacturing (all HVAC/R segments)

 

Smooth Tubes

We supply smooth tubes, which are characterised by their bright, clean and dry internal and external surfaces. We can control the weight and the dimensions of the tube with very close tolerances to ensure trouble-free performance and cost saving.

Our smooth ACR tubes are 100% rotary eddy-current tested to ensure the highest quality.

Applications for Smooth tubes

  • All ACR industries including household refrigeration

 

Hairpins

Luvata is one of the world’s largest producer of thin-wall heat exchanger tubes. In order to further support our customers we have added the capability to provide hairpins in various dimensions with several different tube surfaces. This has resulted in increased efficiency without increasing the size of the heat exchanger, therefore lowering production costs and allowing the use of new environmentally-friendly coolants.

Luvata also offers a variety of other high performance products and solutions for the ACR industry.

ACR tube types

The type most frequently used by the industry we serve is layer-wound coils (LWC), with or without cardboard reels (flanges). Today we mainly supply the most cost efficient types, which are large coils without cardboard packaging, i.e. so called eye-to-sky or bare-pack type of coils.

 

TypeApplication
High performance Most demanding heat exchange applications
Standard Normal heat exchange applications
Lightweight replacement Cost cutting applications

 

All of our different types of tubes meet national and international standards.

Around the Equator

Luvata's annual production of air-conditioning tube would reach over 35 times around the Equator, with single lengths available from a few metres to many kilometres.

Corrosion Solutions

Luvata offers a variety of corrosion solutions including:

  • UNIGUARD®
  • Tinned hairpins

UNILLOY®

UNILLOY is a specially configured alloy for ACR and is patent pending.  It is targeted to reduce metal content and enable the use of new high-pressure refrigerants.
