About
The electric heater is specifically designed to maintain the surface temperature of the manned spacecraft body and the fastening elements of devices and assemblies within a given temperature range. It was first released in 2015 and has a guaranteed service life of 15 years. The estimated production and delivery time is 4 months. The product is not flight qualified but can be adapted to customer requirements. The heater itself is a flexible single-sided printed circuit board built on a thin, dielectric base made of fiberglass. It features a resistive printed conductor made of manganin foil, deposited in a specific configuration. A protective electrical insulating coating is applied over this conductor.
