Description
💧 O&F L-Series Vertical Liquid Receivers
The L-Series is characterized by its vertical orientation and is designed to ensure a constant supply of liquid refrigerant to the expansion device, while providing a storage location for the system’s total charge during pump-down or low ambient conditions.
I. General Technical and Operational Data
| Parameter | Specification | Note |
| Max. Admissible Working Pressure | 2.9 MPa / 29 bar (Approx. 420 PSIg) | This is the standard pressure rating for HFC/HCFC systems (e.g., R22, R134a). |
| Admissible Working Temperature | -10^C to +140^C (Varies by document, typically -29^C to +121^C) | Standard range for refrigeration vessels. |
| Applicable Refrigerants | R134a, R22, R407C, R404A, R507A | Compatible with common HFC and HCFC refrigerants. |
| Connection Type | Inlet: ODS (Outer Diameter Soldering); Outlet: ODS or Cut-Off Valve Assembly | Inlet is typically at the top/side; outlet is via a dip tube at the bottom. |
| Safety Provision | Standard 1/4″ -18 NPT Port | Provision for a Pressure Relief Valve (PRV) or safety plug is standard on all models. |
| Orientation | Vertical | Allows refrigerant vapor to remain at the top and liquid to settle at the bottom via gravity. |
II. Model-Specific Data (Capacity and Dimensions)
The L-Series covers a wide range of capacities, with models generally increasing in diameter (ØD) and/or length (L) as the volume increases.
| Model Number | Internal Volume (Liters) | Inlet/Outlet Connection Size (ODS) | Shell Diameter (ØD) (mm) | Key Features |
| L-4 | 4 Liters | 3/8″ | approx 102 | Small capacity, ideal for compact units. |
| L-6 | 6 Liters | 1/2″ | approx 102 | Includes cut-off valve on the outlet. |
| L-19 | 19 Liters | 5/8″ or 7/8″ | approx 165 | Inlet and Outlet assembled with cut-off valves. |
| L-23 | 23 Liters | 7/8″ | approx 165 | Inlet and Outlet assembled with cut-off valves. |
| L-29 | 29 Liters | 7/8″ or 1-1/8″ | approx 219 | Inlet and Outlet assembled with cut-off valves. |
