The high-pressure receiver also called liquid receiver is generally needed in a refrigeration system when operating less than its full nominal capacity. Liquid receivers are generally installed close to the condenser outlet. High pressure liquid receivers permit also to maintain a sufficient head pressure during low ambient temperature.
The high-pressure receiver permits to hold excess refrigerant which is not in circulation due to lower capacity needs. It’s a storage pressure vessel which is generally sized for 80 % to 100 % of the full refrigeration system charge.
The Docal liquid receiver tank is designed for a huge variety of refrigerants used in industrial refrigeration systems such as R717 ammonia, R744 carbonic dioxide CO2, R290 propane, etc.
Docal custom made high pressure receivers are designed for vertical or horizontal orientation depending on your specifications. Docal liquid receivers are ASME certified (U stamp our UM stamp) and can also bear Canadian registered number (CRN) from CSA B51 for Canada or with National Board for USA. Our liquid receiver can be made of a variety of materials such as carbon steel, 304 or 316 stainless steel or other exotic materials. Post-weld Heat treatment, corrosion allowance and liquid level indicators are available as options.
