The TL-4 circulation thermostat from the TL Primelab family is a reliable and effective solution for maintaining the set temperature of objects in the bath and in the external circuit. This model is designed to work with water as well as non-aqueous fluids, making it a versatile tool for laboratory and industrial processes. Design Features: The intelligent control system adapts the parameters of the PID controller to the type of working fluid, ensuring stable operation of the system even when the network voltage is unstable or the air temperature changes. The circulation pump effectively mixes the coolant in the bath and ensures high accuracy in maintaining the temperature of the external system, both closed and open. A reliable heating element guarantees safety and stable heating of the coolant. The display shows the current and set temperatures, setting values and service parameters, and the multifunctional control knob ensures ease of use. A safety device with sound and light warning automatically turns off the heating in the event of a break in the temperature sensor circuit or the coolant level drops below the permissible level. The working bath is made of stainless steel, has a long service life and is easy to clean. The outer body of the steel bath is thermally insulated and powder coated for safe operation even at high temperatures of the working fluid. The circulation thermostat TL-4 from Primelab is quality, reliability and convenience in one device. Rest assured that your process temperature control is accurate and stable.
