Tubular heater product image

Hasteco offers custom designed tubular heaters in a wide range of sheath material, Diameters, lengths, terminations,wattage. and These heaters can be applied straight or formed into a variety of shapes, Since that, Tubular heaters are the most versatile heating elements and have been widely used in many industries.

Our engineers can assist in specifying the proper configuration to satisfie application requirements based on factors such as cost, maximum temperature, corrosive nature of the material to be heated.

tubular heater for hot runner manifold

There are cartridge and tubular heaters that are most commonly used for manifold heating,Particularly Tubular heaters have proven successful,These tubular heaters are able to be bent and adapted to the shape of the manifold, and have a long service life and linear temperature characteristics.

Finned tubular heater

A series of finned aluminum casting could be attached to the sheath of the tubular heaters, the effective heat radiating surface is increased several hundred times then, and the possiblity of accidental burns is reduced.

Screw plug tubular heater

The screw plug makes tubular heaters are composed of several hairpin tubular heating elements welded or brazed into a threaded screw plug to be plumbed into a fluid flow system for fluid heating. A terminal enclosure usually on the screw plug. The screw plug immersion heaters are used in application requiring the heating of fluids or highly viscous materials, The recommended temperature range is up to 260℃(500℉) as dictated by the physical characteristics of the various fluids and gases.

Teflon coated tubular heater

Teflon(PTFE) coated immersion heaters are used for chemistries or solutions. Teflon immersion heaters immersion heaters consists of tubular heating elements coated with Teflon(PTFE).

Teflon(PTFE), also called Polytetrafluoroethylene, which is a kind of chemical resistant plastic and can Can operate at a maximum temperature of 220°C.  Teflon(PTFE) coated immersion heaters  are resisting pH solutions from 0 to 13, and can be used for Hydrofluoric acids of less than 9% concentration.

Air Duct Heaters

Air duct heaters, essentially assemblies of heating elements in a casing, are designed to warm non-pressurized air. These elements, which can be an open coil, tubular, or finned tubular, are placed inside a duct or insulated body, where passing air is warmed to the desired temperature. For applications demanding high heat output, multiple smaller air tubular heater units can be arranged in series. This approach not only fulfills diverse process temperature requirements but also simplifies maintenance and spare cost.

Circulation Heater

Circulation heaters are efficient electric heating systems that require minimal time and labor to install. They combine heating elements, vessel, insulation, terminal enclosure, mounting brackets, and inlet/outlet connections into a complete assembly. These heaters are designed to heat forced-circulation air, gases, or liquids, making them suitable for in-line or side-arm operations.

Frequently Asked Questions

Tubular heaters are generally energy-efficient and use a moderate amount of electricity. Their consumption depends on wattage and usage duration.

Actually, the tubular heater is a good option for small spaces or supplementary heating, but we don’t suggest using it in the larger space.

Tubular heaters can reach varying temperatures depending on their design and application. Typically, they can operate within a range of 200°F (93°C) to 1200°F (649°C) or even higher.

Yes, tubular heaters can generally be mounted vertically, but it’s essential to follow the manufacturer’s guidelines for proper installation and safety.

Here is a step-by-step guide on how to link tubular heaters:
1) Turn off the power: Before you begin, ensure that the power supply to the area where you will be working is switched off.
2) Mount the tubular heaters: Install the tubular heaters using the provided mounting brackets and clips.
3) On each tubular heater, locate the wiring terminals, and remove any covering or insulation to expose the wiring connections.
4) Prepare the electrical wire.
5) Link the tubular heaters.
6) Secure the wiring.
7) Test the connections.
8) Once you have verified that the wiring connections are correct, turn the power supply back on.

Space heating, industrial processes, frost protection, food industry, greenhouses, horticulture, laboratory, and scientific applications. These are just a few examples of the many uses for tubular heaters. Their adaptability and efficiency make them a popular choice for a wide range of heating applications.

It is difficult to provide a specific time range for the runtime of tubular heaters, as it depends on many factors. However, based on general situations, we can provide a piece of rough information:

In indoor residential and commercial applications, tubular heaters may run intermittently as needed, for instance. In this case, the heater might run for a few minutes to several hours. In industrial and greenhouse applications, the heater might run for several hours or even longer until the desired temperature is reached.

Please note that these time ranges are only references, and the actual runtime may vary depending on the specific situation.
