Mueller Middle East’s Halstead refrigeration service coils are designed to meet the demanding conditions of modern HVAC/R applications and refrigerants. Our coils are cast from the highest purity copper and manufactured to global standards.

Each coil is dehydrated, nitrogen purged, sealed with end caps, and shrink-wrapped individually to maintain high cleanness from our factory to your job site. Our standards ensure long life expectancy for your HVAC/R system devices and equipment.
