Dena Line launches Oil Separators for CO₂ transcritical applications

This innovative mechanical oil filter lasts longer than the standard filtration method, therefore, the entire system does as well,” said Ing. Mauro Avanzini, President and CEO.

The oil separators are to be available in Europe and Russia, with particular interest in the product coming from northern Europe.

We already have pending orders for this product so we are ready to manufacture it; it is also patent pending,” said Avanzini. “We decided to produce oil separators due to the market request to supply a product with no filter replacement cost, especially for the transcritical CO₂ cycle,” he explained.

The oil separators are built using special steels, featuring high reliability and lengthy life-cycle. The system receives the oil through an integrated oil reserve, separates the oil from the refrigerant gas and filters impurities and dirt from the refrigeration or air conditioning installation.
