TK3 100 bar CO2 Oil Level Controller

The TK3 100 bar oil level controller is designed to control the oil level in the CO2 compressor crankcase in order to avoid the compressor to run without oil and so improve its lifetime. TK3 100 bar oil level controller monitors the oil level with the embedded electro-optic sensor and comprises a solenoid valve for oil filling and a relay output contact to give an alarm or directly stop the compressor (through a separate power relay).

230 VAC / 2A alarm relay output is suitable for direct connection in the security chain of the system

Its very compact dual-pitch fl ange-like design let the mounting more easy: the TK3 can be mounted as sight glass replacement directly onto 3 bolts or 4 bolts compressors giving the possibility to rack manufacturers to build more compact units.

If the compressor has a threaded instead of a flaged sight glass, adapter kits are available.

The sightglass is still available and it is on the same side of the LEDs in order to give the complete situation about the oil status in one eye-shot.

Supply voltage 24 VAC

Key features of TK3 oil level controller

Reduced size
High reliability control
Replaceable electronic without depressurizing the system
No need for external pressure adapters
LEDs and sightglass give immediate reading of system status
The TK3 is suitable to work with all the ΔP of the system so there is no need to use pressure reduction components
Reduction of the number of junctions in the circuit with less possibility of having leakages
Usage of less components (simplified circuit and easier warehouse management)
Simplified Installation (cost savings in terms of installation time)
No need for calibrations on the field.
