Applications
These waterproof control boxes designed for vertical mounting on pipes allow to control the surface temperature of pipes on site.
The connection to the heating elements and the temperature sensor is made by a pipe mounting foot incorporating the seal.
The use this model is simple. The use of a wired temperature measurement sensor, which can be disconnected, overcomes the wall crossing problems of bulb thermostats, the capillary of which cannot be cut. Then proceeding to installation of the temperature control unit after mounting the heating cables and the temperature sensor is possible, as well as after installation of the pipe insulation and its protective sheath if they exist.
Main features
Enclosure: IP69K, reinforced PA66, with polycarbonate window access. Sealable cover and window.
Assembly: Pipe mounting by PPS foot with heating cables crossing watertight seal. Two passages are provided in the foot for tightening it on the pipe by two nylon ties or metal hose clamps.
Cable gland and foot: Mounted on a removable board, facilitating assembly. This board has an M25 cable gland for the power supply cable. The heating cables exit through the foot. (The PPS foot is shipped unassembled on the box)
Foot gasket: Is mounted inside the foot as standard, a silicone seal designed for two heating cables and one hole for temperature sensor cable dia. 2 to 3mm. (For more information about these seals, see the catalogue page on 6YTPP pipe mounting legs)
Accessories: Are included two flexible boots in silicone with two bus wire funnels, length 100mm, intended to shield the conductors of the self-regulating cables after cutting off the heating zone. (For more information about these boots, se the accessories pages 6YTNB in this catalogue).
Electrical connection: On internal terminal block with screw terminals
Cable gland: One M25 cable gland for the power supply cable.
Miscellaneous devices: Main illuminated switch and safety fuse.
