40XX Series Suction Accumulator

ACCUMULATOR - Anti-Slug, Industrial Pressure Rating

Function of the accumulator

The accumulator stores refrigerant and ensures stable liquid supply while preventing liquid refrigerant from reaching the compressor.

Accumulator vs receiver dryer

Accumulators manage suction-side liquid; receiver dryers combine storage with filtration for reliable system operation.

Kilterra receiver dryers combine liquid storage and moisture filtration in one precision component for reliable system operation.

Kilterra accumulators and receiver driers are precision-welded to store refrigerant and ensure stable liquid supply for the system.

Kilterra accumulators pass strict pressure and cleanliness tests, widely used in residential AC, refrigeration and heat pump systems.

Key Features

Six core advantages that keep your refrigeration system protected around the clock

💧

U-Bend Suction Tube

The U-bend keeps maximum refrigerant flow while trapping the least oil, so settled liquid is never re-entrained.

🔍

Offset Inlet Guide

The inlet is offset from the U-bend to stop liquid refrigerant entering the compressor directly, eliminating slugging.

🛡️

30bar Design Pressure

Maximum working pressure of 30bar (3.0MPa) meets industrial high-pressure requirements.

🌡️

Epoxy Powder Coating

A corrosion-resistant epoxy powder coating supports long service in harsh environments.

TP2 Copper ODF Ports

ODF connections use TP2 copper stubs for easy field brazing and a reliable seal.

🔧

Multiple Mounting Styles

FIG1-FIG6 foot/mounting styles accommodate a wide range of installation conditions.
