01 Overview

TK4 monitors the oil level with the embedded electro-optic sensor. It comprises a solenoid valve for oil filling and an alarm relay output. It also integrates wireless connectivity capabilities for enhance the control possibilities. The communication with TK4 can be established very easily even when the electronic module is not powered for maximum flexibility.

Key features of the TEKLAB TK4 oil level regulator

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.
Wireless connectivity for enhanced control possibilities and system optimization.

Some advantages of TK4 Oil Level Regulator

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).
Powerful but easy to use wireless connectivity for maximum flexibility.
