TK3⁺ Oil level regulator

Main features

• High reliability ensured by absence of mechanical moving parts.
• Sight glass and electronic LEDs can be checked on the same side where is more comfortable to do inspections.
• Well consolidated steel with fused glass technology and the absence of seals ensures no leakage and good chemical compatibility.
• Direct mounting onto 3/4/6 bolts compressors 
• Left/Right mounting possibilities with the same TK3+.
• Easy maintenance of the coil of the valve and of the Electro-Opticsensor that can be easily replaced without emptying or depressurizing the plant.
• No need to use external pressure reduction devices
• Maximum compatibility with particular media due to the possibility of mounting of different/custom valves
• 230 VAC /2A alarm relay output suitable for direct connection in the security chain of the system
• Adapters suitable for various types of compressors

Application Description

The TK3+ is designed to control the oil level in the compressor crankcase in order to avoid the compressor to run without oil and so improve its lifetime. TK3+ 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).
The output contact (normally open) is closed when the oil level is enough and open if after a determined number of filling cycles the oil level is not restored. Alarm state is represented by the red LED.
The LEDs on the Electronic module give immediately info on the status of the system and act as follows:
Power Light (green colour): always on when power is applied.
Oil Good (green colour): steady on while oil level is good, blinking for a first period of oil missing (even due to turbulence, undulations, etc.) before start filling and is off when filling.
Oil Filling (yellow colour): Off while oil level is good, steady on while injecting oil, blinking while (after filling) TK3+ check if the oil level is restored.
Alarm (red colour): Off while oil level is enough, steady on if after a determined number of filling cycles the oil level is not restored.
Filling cycles continue also in alarm condition and in each phase, if the correct oil level is restored, the oil feeding is stopped and the alarm is deactivated (auto restore from alarm).
