DHE offers Tubular heaters are renowned for their adaptability, durability and reliability. They can be virtually factory-fitted to meet a wide range of industrial heating requirements. The fundamental principle of the design is to enclose a resistive wire or coil in a precisely centered metal sheath, surrounded by magnesium oxide, in order to facilitate the efficient transfer of heat from the coil to the heating medium. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials. Tubular heating elements are capable of conveying heat through all three of these modes: Conduction, Convection and Radiation. Tubular heating elements are available in single-ended and double-ended configurations. Tubular Heaters with a single-ended design have both terminals located at one end of the heater. The other end is sealed. Lead wires that are flexible and are crimped to the terminal pin are equipped with sleeves made of silicone-enriched fiberglass.
The double-ended is highly flexible in terms of bending, particularly when bending in the field. Both single-and double-ended structures have a lot of built-in features that help them last a long time.
DHE offers efficient electric duct heaters for all heating applications. Duct heaters used in forced air applications provide dedicated space heat or supplement existing heating systems. These heaters are equipped with the capacity to heat a large volume of air. They are equipped with the unique capability to both heat and cool the air simultaneously. A duct heater is a device that transfers heat from one source to another. It consists of a set of heating elements that are connected together in a framework or duct. The heating elements are detachable through the housing of this assembly. This eliminates the need to drag the entire heater out of the duct. As a result, downtime costs are reduced as each heating element can be replaced on its own. This type of industrial heater has been developed in a highly adaptable manner, providing the necessary features to be utilized in a variety of commercial and industrial applications.
DHE offers an Industrial air heaters are designed to withstand the toughest conditions of the industrial air processing environment. They are designed to withstand dirt, vibration, and contamination. An industrial air heater utilizes an open coil of the heating element, which is inserted into the metal sheath, to directly heat the air. The design of the system and the direct heating process lead to the most efficient heating and the shortest heating times. Air heaters work by radiating heat into the passing air or fluid. There are various types of air heaters, including finned air heaters, tubular air heaters, and open coil air heaters. These industrial air heaters are available in standard and custom models.

DHE Offer ceramic band heaters are designed to meet industrial needs for high temperature, durable heaters. These heaters are well-suited to meet the demands of today’s new resins, where process temperatures are constantly increasing. This ceramic band heater has spirally wound internal resistance coils that are threaded through interlocking ceramic "tiles". The ceramic core or "mat" of the tiles is hidden under a stainless steel sheet that has serrated edges. The combination of the two makes this heating system flexible and efficient. The heat in the ceramic band comes from the inner coils, which conduct heat at the highest temperatures. They evenly distribute heat through the tiles, which then radiate energy into the barrel. We have a bunch of different ceramic band styles with different configurations.
Ceramic Band Heater Power Saver
DHE also offers ceramic band heaters that are specially developed for injection molding machines and where higher temperatures are required. These heaters can save up to 30% of power. Outer shell temperature will be 70°C at a time of 250°C Temperature measured on the barrel. The element winding is designed to heat the ceramic blocks to the point at which they radiate energy into the barrel as well as conduct energy by being in contact with the barrel.
Perforated Ceramic Band Heater
We also offer perforated ceramic band heaters, which are widely used for PVC injection molding, cooling on extrusion, and blow molding machines. The heater band is 60% open by perforated metal sheet, which ensures maximum surface exposure for better cooling. The heater band is covered with a blower cover for mounting the blower. Advantages of air-cooled over liquid-cooled operations include lower cost, easy replacement, low maintenance, no leakage problems, and uniform temperature control.
