Water Freeze Prevention Device NF Auto Heater GSL Type

A water freeze prevention device that has a temperature control function for the entire heating element.

The NF auto heater GSL type has a small diameter heating element and a structure with excellent lubricity, making it ideal for installation in pipes using the sheath header method.
This is a method in which the positive resistance change of the heating element causes the resistance to decrease (increase in heat generation) as the surrounding temperature decreases, and as it rises, the resistance increases (decreases in the amount of heat generation), causing the heating element to continuously change the current flow.

Features

This is a self-temperature control type in which the entire heating element detects the ambient temperature and automatically controls the amount of heat generated. (common)
Since the initial resistance value when electricity starts is low, the temperature rises quickly even when it suddenly gets cold. (common)
Easy installation by laying the heating element vertically along the piping. (common)
Since it does not use a thermostat, no space is required to install a thermostat. (common)
The smaller diameter of the heating element and the adoption of a fluorine outermost layer provide excellent lubricity and improved passage through the heater guide tube. (GSL type)
The connection mold is equipped with a power indicator lamp that displays the power status. (GSL type)
Excellent durability and weather resistance. (GSL type)
