Norske Backer have introduced an additional option for the Popular range of heaters. This consists of a 2 part lead, the first immersed section is still manufactured as an integral part of the heater using Norske Backer special fluoropolymer cable. The second non immersed part consists of standard electrical cable joined to the heater lead with a secure waterproof splice. This construction maintains the corrosion proof properties of the heater whilst allowing for easier termination for the electrician saving both time and money.
The chemical lead section should be long enough to reach above the surface of the liquid. The splice must not be immersed. The high liquid level is clearly marked on the lead with a red ring. The splice is rated to IP64 (splash proof) however, it has been fully tested in our own laboratory under full immersion at elevated temperature with no adverse effect for a sustained length of time.
