Accumulator is usually a vertical vessel with inlet and outlet connections at top. Due to density difference during cycle operation, liquid refrigerant is accumulated at the bottom of the Accumulator and remaining volume is occupied by the vapor refrigerant.

It has a free-flowing inlet for refrigerant to enter from the Suction line. The outlet is through a ‘U’ Tube. The ‘U’ tube inlet is at the top, with the bend going upto the bottom and connected to the outlet tube.

This U-tube design helps to draw gaseous refrigerant off the top of the vessel. At the bottom of the U-tube, an orifice picks up a small amount of oil and meters it back with the gaseous refrigerant. The small amount of liquid refrigerant will boil off in the suction line. The oil will be carried with the gaseous refrigerant back to the compressors.

The Suction Line Accumulators must be installed in a vertical position, after the Evaporator and as close possible to the Compressor and at the same level as compressor.

On systems with a reversing valve and on heat pump systems, the accumulator should be installed between the compressor and the reversing valve.

Dry All offers both Vertical and Horizontal type Accumulators. But Horizontal Accumulator are available only as customized model on customer request.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has...

Accumulator should be on basis of the following parameters:

• If system is using TXV, holding capacity should be minimum 50% of total refrigerant charge of the System.
• If System with Capillary tube, holding capacity should be minimum 70% of total refrigerant charge of the System.
• The inlet and outlet connection should be same as or larger than Suction line size of the system.
• Note: The volume should never be below 50% of the refrigerant charge.
• Do not choose Accumulator based on the connection sizes only.

Dry All Accumulators off-the-shelf models are available from 0.5 Litre – 35 Litre capacity.

We have Accumulators available with MWP ranging from 25 bar–31 bar. Please check with us for more information.

Yes, certain range of Dry All Accumulators are UL listed. The UL File number is SA45127-20181127

Two type of mountings are available:

• a) Bolted & Nut (Stud type)
• b) Mounting Flange

Yes, we make customized Accumulators as per customer design and specification. Please contact Dry All for more details on the process, models available, MOQ, Price, etc.

All models above 3” Diameter & UL listed has inbuilt fusible plugs.

We strongly recommend to install Suction Line Filter Drier / Suction Line Filter before the Accumulator. This prevents the oil pickup orifice in the accumulators from clogging in case the system oil is carrying wax or other debris.
