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

• Fully Integrated & Protected Design: The module pre-integrates the PTC heater, a safety fuse, and a regulating thermostat into one assembly. This eliminates the need for sourcing and wiring separate components, reducing installation time and potential points of failure.

• Built-in Safety Fuse: Incorporates a dedicated fuse that acts as a fail-safe, automatically cutting power in the event of a current overload or short circuit, thereby protecting the heater module and the wider HVAC system from electrical damage.

• Integrated Control Thermostat: Features an embedded thermostat that accurately monitors and regulates the heater's surface or output air temperature. It automatically cycles the power to maintain a set temperature range, preventing energy waste and ensuring consistent, comfortable heat output.

• Self-Regulating PTC Core: At its heart, the PTC ceramic elements provide inherent safety by sharply increasing resistance as temperature rises. This natural property prevents overheating and allows for stable, efficient operation even if the airflow is partially blocked.

• Plug-and-Play Installation: Designed for straightforward integration into existing AC or heat pump units. It typically comes with standardized connectors or terminal blocks, allowing for direct replacement of older heating elements or easy addition to auxiliary heat circuits.

• Robust & Compact Housing: Encased in a durable, often flame-retardant housing that withstands the temperature fluctuations and vibrations inside HVAC equipment, ensuring long-term performance.

Application

This intelligent module is designed for seamless integration into systems requiring reliable supplemental heat:

• Air Conditioner & Heat Pump Auxiliary Heating Kits: The primary application is as an add-on or built-in heater for split-system air conditioners, ducted mini-splits, and packaged heat pumps to provide instant backup heat during defrost cycles or in extreme cold when the heat pump's efficiency drops.

• Fan Coil Unit (FCU) Enhancement: Installed within commercial or residential fan coil units to provide zonal electric heating, improving comfort in individual rooms or spaces served by a chilled water system.

• HVAC System Retrofit & Repair: Serves as a modern, safe replacement for old, inefficient, or failed resistive heating elements in air handlers and rooftop units.

• Ducted Electric Furnace Components: Can be used as a heating block in small electric furnaces or dedicated makeup air units where controlled, safe electric heat is required.
