KERMI PTC preheater Ø 180 - 1400W (DX5 DX6 X500) Y340418000201K

Pre-heater KERMI PTC Ø 180 - 1400W

This advanced heating device is dedicated to Kermi recuperation systems and is also compatible with DX5 and X500 models. The anti-freeze pre-heater utilizes PTC (Positive Temperature Coefficient) technology – a semiconductor heating element that automatically regulates its power depending on current needs. This ensures efficient air heating from the intake, while minimizing energy consumption.

Application and installation

The heater is designed for mounting on an intake duct with a diameter of 180 mm or directly at the inlet to the recuperator. It has two connection cables: a power cable with a plug and a control cable, which is connected to the recuperator's control board. This connection method enables integration with the control system and optimizes device operation.

PTC technology – savings and efficiency

The key to the operation of this heater is the use of a PTC element. This material is characterized by self-regulation – as the temperature rises, its resistance increases, which leads to a decrease in power consumption. This means that the heater only draws as much energy as is necessary to maintain the set temperature, which translates into real savings. In addition, this technology extends the life of the device and ensures stable operation.

Benefits for the installer and user:

• Self-regulation: Eliminates the risk of overheating and ensures optimal air temperature supplied to the recuperator.
• Energy saving: Variable power consumption adapted to needs minimizes operating costs.
• Simple installation: Two connection cables facilitate installation and integration with the recuperator control system.
• Long service life: The use of high-quality materials and PTC technology guarantees device reliability.
• Lower defrost threshold: Allows for efficient operation of the ventilation system even at low outdoor temperatures.
• Protection: Equipped with an automatic switch for added safety.

The KERMI PTC pre-heater is an investment in the comfort and efficiency of a mechanical ventilation system with heat recovery, which brings benefits to both installers and end-users. The rated power of 1400 W allows for maintaining a balanced ventilation even in difficult weather conditions, and the voltage of 230 V ensures easy connection to a standard electrical installation.
