TK3+ 80 bar Version
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.
Key features of TK3+ oil level controller
- 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 with absence of seals ensures no leakage and good chemical compatibility
- 24 VAC / 230 VAC power supply options
- Easy maintenance of the coil of the valve and of the Electro-Optic sensor that can be easily replaced without emptying or depressurizing the plant
- 230 VAC /2A alarm relay output suitable for direct connection in the security chain of the system
- Adapters suitable for various types of compressors
- Unit conform to directives 2014/30/UE and 2014/35/UE
- Extremely compact dimensions
- Left/Right mounting possibility with the same TK3+
- 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)
