RAYCHEM FROSTGUARD-8M - Self-regulating heating cable for pipe heating, terminated with 230 V plug, length 8 m - (493074-000)
RAYCHEM FrostGuard self-regulating heating cable for heating steel and PVC pipes in which water flows is installed as frost protection. Terminated with a two-meter power cable with a plug for contact.
- Designed for pipes: PVC, metal, stainless steel and copper.
- It protects against frost, and thus against freezing.
- Despite its small size, the heating cable is very durable.
- It adjusts its heating power to the ambient temperature, so it automatically delivers more power on colder days and less on warmer days, saving energy.
- FrostGuard heating cables can also be used inside drinking water pipelines. They have Swedish approval for use with drinking water.
- FrostGuard is a self-regulating cable that can cross and contact each other without burning out.
State-of-the-art self-regulating technology in FrostGuard pipe heating cable
Self-regulating heating cables deliver the right amount of heat exactly where it is needed. When the ambient temperature drops, the cable generates more heat. When the temperature rises, the amount of heat generated decreases.
- Safety - wires can be crossed without risk of overheating.
- Optimum energy consumption.
- Can be installed on PVC pipes.
- Heating power at 5°C on metal pipe 10 W/m.
- Heating power at 0°C in water 20 W/m.
- A - Low ambient temp. = high heating power.
- B - Moderate ambient temp. = low heating power
- C - High ambient temp = almost zero heating power

Installation of the cable on the outside or inside the pipe?
External mounting is much simpler but possible only for pipes to which we have access. Suitable power heating cable is enough to install in the amount of one strand along the pipe and insulate.
The case is different when the pipe freezes in the wall or floor and we do not have access to it to fix the cable. There is also a solution for this. The heating cable is installed inside the pipe, it is introduced with the help of a special pressure gland RAYCHEM ETL-GLAND-01 (to be purchased separately). It is absolutely necessary for this purpose to use heating cables approved for installation inside pipes and for contact with drinking water, such as RAYCHEM FrostGuard.

Is an additional thermostat needed for the self-regulating cable?
RAYCHEM FrostGuard self-regulating heating sets do not require thermostats, nevertheless, to minimize electricity costs completely, a RYCHEM FrostGuard-ECO socket thermostat can be used (to be purchased separately). The socket thermostat is designed for plug-ended heating cables mounted on and inside pipes.
FrostGuard-ECO is compatible with the cables we offer. Why should you opt for it? Because it guarantees you that the system will work only when needed to protect the pipeline. This solution will allow you to save up to 80% of energy. Add this product to your cart, install it in your home and see for yourself!
