Indus pioneered introduction of Conveyorized Auto-Brazing technology to produce up to 12 rows of All Aluminum HEX Coils using Al fin with Al tube diameter ranging from 5mm to 12.7mm (1/2”) in both plain & rifled surface.
Indus offers a wide selection of Fin Pattern using bare as well as pre-coated (hydrophilic / hydrophobic) fins with varied fin pitches and tube thicknesses to meet customers’ design pressures per industry standards for all conceivable applications.
Our products are UL Certified & compatible with commonly used refrigerants in the industry including natural & flammable low GWP refrigerants like R290.
Indus All Aluminum Coils are
- Direct substitute to Cu tube Al fin Coils with similar performance & design pressures
- Durable with no occurrence of Galvanic corrosion & no effect of formicary corrosion
- Light weight, low cost to offer competitive advantage to customers
Indus all Aluminum Coils come with robust Copper End Connection for ease of assembly at customer’s end. Our engineering team works closely with customers’ engineering team to select an optimum design to offer cost effective product to meet their performance requirements.
