Oil regulation system

LEVOIL - Mechanical oil level regulators and adapters


Technical description
• Monitoring and automatic upholding of the optimal oil level in the crankcase of each compressor of refrigeration and air conditioning multi-compressors installations.

• The oil level regulators LEVOIL participate in the return of the oil into the compressors and to their proper functioning; they are only used in low pressure oil return systems.

• They allow the installation of compressors at unequal heights or different level of oil.

• They allow, on the same installation, the connection in parallel of compressors with different cooling capacities or operating at different regimes..

LEVOIL - Mechanical oil level regulators and adapters
CARLY advantages
  • Maximum working pressure 46 bar.
  • Optimized range of oil level regulators equipped with two 7 holes universal flanges in order to be mounted on most of compressors available on the market.
  • Resistance to higher pressure and limited foaming phenomenon inside the regulator due to the spherical design.
  • Internal valve/needle/float oil return system, efficient and reliable. Minimizes the bad effect of foaming and ensures a good stability of the oil level.
  • The density and viscosity of oils have nearly no effect on the regulator LEVOIL®.
  • Due to the large pressure differential (1bar to 4,5bar), the basic model LEVOIL 23 is suitable for mounting on 2 levels cascade packs (supermarket application).
  • Model LEVOIL 33 RE with adjustable ΔP from 1 to 6,5 bar and a pressure equalization connection.
  • For the regulators with 7 holes flanges, the visualization of the oil level is facilitated, due to left or right mounting possibilities.
  • Installation possible on the right or left side of the compressor, thanks to the centered inlet oil connection.
  • Oil inlet connection inclined backwards, in order to avoid the cylinder heads of the compressor.
  • Small volume of oil retention in the lower part of the LEVOIL®.
  • Wide range of adapters allowing connection of the LEVOIL® on most of the compressors available on the market.
