RG RANGE

Immersion heaters for aggressive baths in the RG range are used for heating the different types of
substances and solutions of a chemical or electrolytic, surface-coating process

General characteristics

• Heating element manufactured with high-quality ceramic support and Ni-Cr alloy resistive wire

• Head in EPDM for all models with sheath Ø25, Ø30 and Ø33 mm and also for models with lead sheath in Ø52 mm.

• Bakelite head with IP65 protection degree for the porcelain models of Ø40 mm and all models with sheath Ø52 mm except for models with lead sheath.

• 2 or 3 wire silicone hose lead + Earth of 1500 mm long (for different lengths of lead, indicate on the order)

• Class I electric heater

• Standardised voltages: ~230 V; 2~400 V; 3~400 V

Method of use:

The immersion heater is supplied without any control elements, the user having to connect the different electrical circuits and drives to start the immersion heater
running.

• Periodically check the air-tightness of the head to make sure there is no deterioratio of the internal connections due to corrosive actions of vapours or liquids.

• The immersion heater has a mark which signals the heated zone. To ensure correct functioning, it is vital that this mark is always completely submerged

• For its electrical connection, it must be submerged in the bath.

• To remove it from the bath, it must be disconnected electrically and left for 15 minutes or until the heating element has cooled down.

• Before installing the immersion heater, check that the sheath material is suitable for the type of bath in which it is to be submerged. To do so, and only as a guideline, we show below a table with the recommended sheath materials per type of bath. The final choice may be based on working conditions, recommendations by the corrosive material manufacturer, or else, on a preliminary test. Heattec cannot be held responsible for potential problems caused by corrosion, as different working conditions and other factors, often unknown, can modify the efficiency of the sheath.

NOTE: The special characteristics of Teflon make it able to work in a wide range of corrosive liquids, and would therefore be suitable for any of the baths indicated in the table included. The exception is to be found in baths with hydrofluoric acid or solutions with fluoride base. In these cases, Teflon is NOT appropriate.
