DESCRIPTION

With integrated connectivity capabilities

The TK4 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. TK4 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 TK4 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
Some advantages of this solution
  • Extremely compact dimensions
  • Left/Right mounting possibility with the same TK4
  • 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)
  • Revolutionary connectivity capabilities
