Tubular heaters
Tubular heaters are used to heat air, gases, liquids and solids. Tubular heaters are widely used in various industries. La possibilità di qualsiasi forma di caldamento, consente di essere adaptati per i requisiti specifiche, che rendono una soluzione ideale per molti sistemi di riscaldamento. They can be found in countless everyday electronic equipment, where they play the role of the main components.
They are extremely durable and often used as components of high-power heating units. They can work even in very demanding environments, resistant to chemicals, temperature and pressure.
Their construction allows for easy adjustment of length, diameter and shape to a specific application.

Tubular heaters for operation in air
Heaters operating in air are made of stainless steel in degrees min. AISI321. The shape of the bending depends on the needs of the customer. Thanks to the radiator made of stainless steel, the surface area and heat transfer efficiency are increased. Heaters can be mounted using stuffing boxes, heads, brackets, fixing plates, blind flanges etc.
Available variants:
- diameter of the heater Fi 8,5, radiator Fi 25
- diameter of the heater Fi 10, radiator Fi 29
- diameter of the heater Fi 13, radiator Fi 34

Tubular heaters for liquid operation
Tubular heaters designed for operation in liquids are made of 316L or INCOLOY 800 stainless steel. Elaborate parameters (power, tension, bending and type of fastening) depending on the wishes of the clients. Tubular heaters are usually mounted in heads: 1”, 1 ¼”, 1 ½”, 2”, 2.5”, made of brass or stainless steel.
At the request of the customer, it is possible to create a stainless steel head with any type of thread. The heating element can be fixed in M14x1.5 or 3/8” chokes. Heaters in heads and chokes are connected by brazing (silver) or in the case of aggressive liquids — TIG welding. The current output of this type of heaters is standard (screw M5, pin, threaded terminal M4). In the case of 1 ½”, 2” and 2.5” heads, the entire connection can be covered with a protective box. On request, we produce heaters with a built-in thermostat or with the sheath itself under the temperature sensor.

Tubular heaters for work in mold channels
A tube heater designed for injection molds can be of different shapes, so we manufacture them according to the specifications provided by the customer. A heater made in this way is doginized, and then fixed in the distributor.
Tubular heater for defrosting
Tubular heaters for defrosting cold counters have additional, hermetic insulation at the current connection of the heater to the cable. As with the other types of heaters, they are made according to the individual needs of the customer.
