What is PTC in room heater?
Positive temperature coefficient (PTC) heaters consist of specialized heating discs built from advanced ceramic materials. These safe, powerful, and energy-efficient heaters allow for exceptional heat production and transfer within even the smallest spaces.
Is PTC heater good for health?
When you rely on a single-point sensor to assume the temperature of an entire surface, this poses more than a functionality issue. It also creates a significant safety risk. Enter, Positive Temperature Coefficient (PTC) heaters. A PTC heater is safer, more reliable, and more consistent than a traditional heater.
Does PTC heater burn oxygen?
Typical heating elements that use a resistance wire to generate heat, PTC heating elements are made as ceramic stones, doped with barium titanate. PTC devices do not burn oxygen making them safer to use in controlled environments.
Does PTC heater reduce humidity?
Anti-Condensation As moisture problems take on increasing importance in plant environments and USDA and federal requirements grow stricter, processors are looking to PTC heating technology to reduce humidity and resulting bacteria growth on food machinery and equipment.
How does a PTC heater work?
Operation. When a voltage is applied to a PTC heater electrical current flows through the material and the resistivity of the material causes it to heat up (P(T)=U∧2÷R(T)). As it heats up the resistivity increases rapidly and the power (heat) produced decreases.
How efficient are PTC heaters?
The heating element inside a PTC heater has a positive temperature coefficient and its resistance increases with temperature. This makes a PTC heater inherently both safe and efficient; the PTC heater will stop drawing current if it overheats and it only draws the current it needs to maintain temperature.
How hot does a PTC get?
This high-performance capability allows manufacturers to set target temperature zones between which the PTC heater functions. While all PTC ceramic heating materials function best between -40°F and 158°F, skilled manufacturers can set a specific zone in which the heating product operates.
