Duct heaters are designed to heat fresh air supplied through the ventilation system. The device is an integral part of the system and is not intended for standalone operation.
The heater is designed for prolonged continuous operation without disconnection from the power supply.
The supplied air must not contain flammable or explosive mixtures, chemical vapors, sticky substances, fibrous materials, coarse dust, soot, or oily particles, as well as environments that contribute to the formation of hazardous substances (toxins, dust, pathogenic microorganisms).
The device is intended for indoor use at ambient temperatures from -30 °C to +50 °C and relative humidity up to 80%.
The heater is classified as an electrical device of class I. The level of protection against access to hazardous parts and water ingress complies with the standard IP40.
The design of the heater is constantly being improved, so some models may differ slightly from those depicted in this document.


PTC heater is a modern electric heating device that uses ceramic materials with a positive temperature coefficient. These materials increase electrical resistance during heating, allowing the heater to self-regulate its temperature. This makes PTC heaters safe, energy-efficient, and maintenance-free.
Easy to install. Perfect compatibility with Mycond ventilation systems.
