Introduction

The main function of the suction accumulator in a refrigeration or heat pump system is to protect the compressor from liquid refrigerant. Liquid refrigerant can dilute the oil, wash out the bearings, and damage valve reeds. The un-evaporated portion of refrigerant returning in the suction line is trapped in the accumulator, allowing only vapour refrigerant and oil to leave and return to the compressor.

Heldon suction accumulators comprise of a sufficiently sized vessel with an optimised ‘’U’’ shaped internal tube to minimise pressure drop and maximise flow through the vessel. Positive oil return is accomplished through a strainer protected injection orifice. The inlet to the U tube is located above and behind the vessel inlet to eliminate any possibility of high velocity liquid carryover.

Heldon suction accumulators are constructed from Steel with solid copper connections and supplied with a plugged pressure relief valve connection on larger models.
