FLEXDRAIN drain-line heaters include a heating part and a cold power cable at one end. These drain-line heaters are used in the refrigeration industry for freeze protection of drain pipes and for condensate in the drain pan. Extremely flexible, these drain heating cables are quick, safe and easy to use. Standard sizes or designs as requested these heater cables solve many of the problems in the installation you may be faced with.

CSC2 heaters cables are designed to be laid inside pipes for draining water from thawing refrigeration equipment installed in cold rooms. They operate only during thawing cycles. To ensure that these heating elements enjoy a long service life, we recommend using a control device. Note: The most commonly used power rating is 50 W/m. However, for plastic pipes, we strongly recommend using the 40W/m range.
