three-phase screw heating unit TJ 6/4“ – 6kW

Description of the heating unit:

The screw-in electric heating unit is intended exclusively for heating water. It is designed as an additional source of heating for storage tanks connected in a system without solar collectors but also with solar collectors. It must not be used in stainless steel tanks. Types with an extended cooling part can only be used in steel storage tanks.

The water is heated by a tubular heating element. The safety and operating thermostat sensors are located in the sump (both devices are in one block). The operating thermostat controls the set water temperature. In the event of its failure, the safety thermostat switches off the electrical power supply in all poles in the temperature range of 0 - 90 °C.

Photovoltaics and heating units with storage tanks:

Heating units can be effectively used in conjunction with photovoltaic power plants (PVP). Thanks to the possibility of powering from surplus electricity from PVP, it represents a suitable solution for maximizing energy.

The heating units are AC, they cannot be connected to DC directly from the panels!

The composition of the heating unit and the diagram with the size table:

The heating unit consists of an electric heating element with a connection thread G 6/4“

The heating elements are insulated from the metal head with a connection thread. A leakage/grounding current resistor is installed, which is part of the cathodic protection of the tank against its corrosion.

The design of the heating element partially compensates for the potential difference created by the electrochemical reaction in the tank filled with water and the heating element.

The service life of the anode is extended, and the resistance of the heating element/element is increased. Under the electrical installation cover, there is an operating thermostat, a safety thermostat, a control lamp for the body operation and a connection terminal block.

Operating the heating unit:

The simple operation of the TJ 6/4" consists only in setting the desired temperature on the thermostat control knob. Setting range 5 - 74 °C. The recommended set temperature is approximately 60 °C. Symbol * anti-freeze protection 5-8 °C. The illuminated indicator light signals that the unit is in operation.

The product is not intended for use by:

• persons (including children) with reduced physical, sensory or mental capabilities 
• with insufficient knowledge and experience, unless they are supervised by a responsible person or have been properly trained by them.
