Components for CO2 transcritical
Components
Oil separators for transcritical
CO2 application
The ESK oil separator series BOS2-CDH-… has been especially designed for transcritical applications. The oil separators are equipped with coalescence filter elements for the efficient removal of oil. The filter elements of the flanged versions can be exchanged.
Instead of an internal float valve the separators are equipped with a connection for an oil level sensor. The standard versions have a 1/2”NPTF connection. Alternatively oil separators can also be ordered with a connection for the ESK oil level control type OSC.
Oil Reservoirs for transcritical
CO2-Application
In the oil reservoir any refrigerant trapped within the oil is boiled-off and the oil is cooled and kept available. ESK-oil reservoirs for transcritical CO2 application are equipped with three sight glasses without float ball. The selection of oil reservoirs is described in the following selection chart.
Suction Line Accumulators for transcritical
CO2 application
Manufacturer of compressors for transcritical CO2 application advices fundamentally the installation of an suction line accumulator in respect of CO2 behavior.
