Introduction
Electric heaters in HVAC systems are used as either a primary or secondary source of heating.
At Clima Plus, we deal in open element and finned tubular heaters mainly. Open element electric heaters utilize high resistance Nichrome wire (80% nickel, 20% chromium) to provide heat to the airstream.
Nichrome wire has a high maximum operating temperature, long-life and a high resistance to corrosion.
Our finned heaters are constructed using robust tubular element as the basis of construction. Fin material is continuously spiral wound tightly onto the element surface to increase the convective surface area for air and non-corrosive gas heating. Fin spacing and size have been designed to optimize performance. Steel finned units are then furnace brazed, bonding the fins to the sheath to increase conductive efficiency. This allows higher wattage levels to be achieved in the same flow area and produces lower sheath temperatures prolonging heater life.
For higher temperature or more corrosive applications, stainless steel fins securely wound on alloy sheath are available. Protective coatings are also available for use on steel finned heaters for mildly corrosive or high humidity applications.
