Alvian Heating

Thermocouple A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming electrical junctions at differing temperatures. A thermocouple produces a temperature-dependent voltage as a result of the thermoelectric effect, and this voltage can be interpreted to measure temperature. Thermocouples are a widely used type of temperature sensor. Commercial thermocouples are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self-powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degree Celsius (°C) can be difficult to achieve. Thermocouples are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. Thermoc...

Leister & Bobbin 1. Leister Heater     Leister hot-air systems are deployed in countless industrial production processes. There is hardly an industry which does not profit from the diverse advantages – whether through cost-effectiveness or because many processes simply become more efficient with hot-air.   2. Bobbin Heater Features Variety of diameter option from 25mm to 65mm Can be designed in single phase, two phase or three phase option Length from 50mm to 2000mm Faster heating due to larger heating area Temp range for up to 600 deg C Application Industrial washing machines Furnaces Baking Ovens Scientific and lab equipment

In-Line Heater    In-Line Circulation heaters are powerful, electric inline circulation heaters constructed of a screw plug or flange-mounted tubular heater assembly installed into a mating tank or vessel. Inlet and outlet nozzles in the vessel permit liquid or gas flow into and out of the circulation vessel. Standard design circulation heaters use standard screw plug and flange immersion heaters in order to allow for easy replacement and retrofit. Custom units can be designed to suit your request.

Immersion Heater 1. Flanged Immersion Heater    Flanged heaters are commonly used in many chemical, petroleum, and water-based applications. Consisting normally of an ANSI rated flange with several hairpin elements or bugle tubular elements extending from the face of the flange, this electric heater uses direct heat application to the liquid medium. A thermowell is often used within the bundle of elements to allow for a probe (either a thermocouple, RTD or basic mechanical thermostat) to relay temperature readings to a digital control panel that cycles and maintains the desired target temperature. Often a high limit sensor is also used to help protect liquid mediums from overheating and, offers protection to the flange heater as well.    2. Screw Plug Heater    Screw plug heaters are an easy way to heat up solutions in smaller containers that also require controls. Mechanical thermostats or Digital control panels can ...

Finned Heater    Finned Tubular Heater is a pipe-finned heater element and the most suitable solution for air heater. It is often used in the assembly of a blower so that the heat generates more leverage and can be evenly distributed inside or outside a room that has been prepared.    You can order a custom shaped finned heater by contacting us, and also the power, voltages, and current can also be adjusted to fit your needs. W Shaped Finned Heater U Shaped Finned Heater Straight Shaped Finned Heater

 Electric Furnace    An electric furnace is similar to a conventional gas forced-air furnace except that it produces heat with electric heating elements instead of gas burners. Circuit breakers that control the heating elements may be either inside or outside the cabinet.    One advantage of electric heating over gas and other combustion fuels is that electric heating doesn’t give off carbon monoxide. This is good for the environment and makes the unit easier to install because it doesn’t require a flue to carry combustion gases outside. But again, the big downside is the high cost of electricity in most regions. For this reason, heat pumps make more sense if you want to use electricity as a fuel.

Cartridge Heater    Cartridge Heater is an efficient and excellent heater for heating processes using Dies or molds. It is usually applied in the heating process of packaging machinery. The dimension and power can be adjusted according to customer’s demand. The cartridge heater can reach temperatures up to 1,400ºF (760ºC) It is widely used for plastic packaging machinery (horizontal and vertical types), ceramic press/press machine, and etc. Standard Cartridge Heater L Shaped Cartridge Heater Finned Cartridge Heater

Cast In Heater Cast-In Heater is a heating element designed from a tubular heater to a single unit-shaped band or strip through a casting process (iron, brass, or aluminum). This heater is also a form of heating element development, which applications and installations are the same as on Bands and Strip Heater. However, this heater has several advantages that are not owned by the Band and Strip Heater. The advantages of Cast In Heater, among others: More Heavy Duty Maximum operating temperature 500º C Available materials: Iron Brass Aluminum Maximum operating temperature tailored to the type of metal used in Cast-In Heater, among others: Cast In Iron: 500º C Cast In Brass: 400º C Cast In Aluminum: 350º C Applications: Extruder Barrels, Die Heating, Metal Block Heating. The dimension and power can be adjusted according to customer’s demand Aluminum Cast In Steel Cast In Brass (Kuningan) Cast In

Band Heater    Band Heater is a heater that is usually used for plastic processing applications in the form of cylinders. The dimension and power can be adjusted to customer’s demand or based on sample goods. In general, the dimensions are often used in industries ranging from Ø 25 to 500 mm. Mica band heater is one of the cheaper products that certainly has limitations when compared with ceramic band heater. The generated power from 50 – 10,000 Watt can be applied to injection/extruder machines. 1.
