Our liquid receivers are designed to stabilize refrigeration and heat-pump systems by storing liquid refrigerant, ensuring liquid-only feed to the expansion device, and providing sufficient pump-down volume during service. The vessels feature a corrosion-resistant powder-coated shell, optional sight glass and service valve, and multiple port layouts to fit vertical or horizontal installations.

How to size(rule-of-thumb)
For pump-down and stable liquid feed, select a receiver whose usable volume is at least the total system refrigerant charge at ambient conditions, typically using a fill ratio ≤ 80% to allow thermal expansion.
rule of thumb
Example:
If the system charge is 6 kg and liquid density is 1.10 kg/L, then
V ≥ 6 / (1.10 X 0.8)≈ 6.8 L
→ choose ≥7–8 L.

FAQ
It stores liquid refrigerant, ensures liquid feed to the expansion device, and provides pump-down volume during maintenance.
Make sure its usable volume can hold the entire system charge at the intended ambient, typically using ≤80% fill ratio. See the sizing note above.
