Product Description – Suction Line Accumulator with Internal Heat Exchange Coil
1. Product Overview
The suction line accumulator with internal heat exchange coil is specially designed to prevent liquid slugging in refrigeration and air conditioning syste
ms while improving evaporation efficiency. It incorporates an internal coil that uses suction line heat to assist in vaporizing residual liquid refrigerant, combining protective and energy-saving functions.
2. Structural Features
· Vertical cylindrical shell with multiple copper tube connections (inlet, outlet, oil return, and heat exchange).
· Built-in heat exchange coil to enhance refrigerant vaporization.
· High-strength steel construction with corrosion-resistant coating.
· Oil return design at the bottom to maintain compressor lubrication.
· Available in different volume capacities from 1.6L to 18L.
