Description

The Metal Bracket PTC Heater is a purpose-built, high-efficiency heating unit designed specifically for preheating cold fresh air in ventilation ducts. Operating at 3500W with robust PTC (Positive Temperature Coefficient) ceramic technology, this heater effectively raises the temperature of incoming outdoor air before it enters a building's HVAC system or occupied spaces. Its defining feature is an integrated, sturdy metal mounting bracket, ensuring secure, stable, and simplified installation directly within air ducts or plenums. This design is ideal for improving indoor air quality and comfort while protecting HVAC equipment from extreme cold air intake.

Features

• Integrated Metal Mounting Bracket: The heater comes pre-equipped with a durable, corrosion-resistant metal bracket. This allows for easy, tool-free, or minimal-effort installation, providing a rigid and reliable hold within the ductwork without the need for additional fabrication or supports.

• Optimized for Fresh Air Preheating: Specifically engineered to handle the challenge of heating cold, dense outdoor air. The 3500W power rating provides substantial heat output to efficiently raise air temperature, preventing drafts and reducing the load on primary heating systems.

• Safe & Self-Regulating PTC Core: Utilizes advanced PTC ceramic heating elements that automatically regulate their temperature. As the target temperature is reached, electrical resistance increases, preventing overheating and ensuring inherent operational safety and energy efficiency.

• High Airflow Compatibility: Designed with an open, finned structure that minimizes airflow resistance (pressure drop), allowing ventilation systems to maintain required air exchange rates without overworking the fan.

• Durable Construction: Built with high-grade aluminum fins for optimal heat transfer and a rugged metal casing that withstands continuous operation in varying temperature and humidity conditions found in fresh air streams.

• Easy Electrical Integration: Features standard, clearly marked terminals for straightforward connection to a 3500W-rated 220V circuit, often compatible with external thermostats or HVAC controllers for automated operation.

Application

This heater is a dedicated solution for systems that introduce and condition outdoor air:

• Fresh Air Intake Ducts in HVAC Systems: Installed in the fresh air intake duct of central heating systems, Heat Recovery Ventilators (HRVs), or Energy Recovery Ventilators (ERVs) to preheat incoming cold air, preventing coil freezing and improving overall system efficiency.

• Dedicated Outdoor Air Systems (DOAS): A core component in DOAS units that provide preconditioned (preheated) fresh air directly to spaces or to other HVAC equipment.

• Commercial & Industrial Ventilation: Used in factories, workshops, or agricultural buildings where large volumes of fresh air are required but must be tempered to avoid thermal shock, condensation, or discomfort.

• Parking Garage Ventilation: Helps temper cold outdoor air introduced for air quality control in enclosed parking structures, improving safety and comfort.

• Preheating for Heat Pumps & Air Handlers: Protects the evaporator coils of air-source heat pumps and air handling units from frost buildup when using cold outdoor air for ventilation or economizer cycles.
