In a refrigeration system, oil accumulation in heat exchangers shall be avoided to maintain a good efficiency. Indeed, too much oil presence in evaporator or condenser affects negatively their efficiency since the oil will act as a thermal barrier in those heat.
Oil pot collects the mixture of refrigerant and oil that typically accumulate in the bottom of pressure vessels. Moreover, the oil pot allows to isolate most of the oil at a single location to easily drain it from the system during maintenance.
Docal’s custom oil pots can be designed in endless configurations and able to withstand pressures up to 2 000 psig (140 barg). Ammonia oil pot, specifically designed for use with ammonia refrigeration system, are also available. Certified according to the latest ASME standards, our oil pots are available with National Board (USA) or CRN (Canada) certifications. Post-weld Heat treatment, corrosion allowance and oil heater connections available as options.
