How Portable Battery Heaters are Beneficial for Demanding Applications

portable battery heatersPortable battery heaters are among the important supporting heating products that are used in demanding applications in industries such as aviation, military, naval, and aerospace, to name a few. They are designed to keep battery or battery packs at optimal operating temperatures in sub-zero climates.

Battery heaters are typically heated using flexible heaters manufactured with silicone rubber. Silicone rubber can be waterproof and is chemical resistant. Silicone rubber can also be cured to fit 3D shapes making it the ideal material for portable battery heaters. Many models available are self-regulating, eliminating the need for active thermal management helping to reduce cost and complexity.

When producing portable batter heaters, Birk Manufacturing ensure that their design and manufacturing techniques all adhere to industrial, commercial, and military standards including:

All About Silicone Rubber Heaters: Industrial Applications and Operations

Certain applications need to undergo heating processes up to a particular temperature and silicone rubber heaters perform diligently in these cases. These can be defined as lightweight and flexible heaters that are capable of heating up to 450°F. Being a flexible heater, it can be integrated with the surface that requires heating and can be easily affixed or connected with other parts of the system.

The major benefit that lies with silicone flexible heaters is that they transfer heat with uniformity and rapidity. This is mainly because of 3 obvious aspects – 1) the thin construction of the heater 2) the uniformity of its heating pattern and heating circuit and 3) its closeness to the surface of the application.

Distinguishable features of silicone rubber heaters and their types

Although thin and flexible, silicone rubber heaters are known to be rugged and capable of maintaining dimensional stability. This is because the fiberglass grid of these heaters firmly supports the silicone sheets, which in turn encompass the heating elements of this device.

Being resistant to moisture and chemicals, silicone flexible heaters are considered to be convenient to work with. These are compatible with both flat and curved surfaces and can be factory vulcanized for being used in metallic surfaces. Capable of accommodating cut-outs and holes, silicone heaters can be constructed with thermostats, RTDs, thermocouples or thermal fuses. When it comes to fastening the heaters to a surface, a pressure sensitive adhesive (PSA) vulcanization or RTV can do the job.

Temperature Sensors: Compare and Contrast Between Thermocouples and RTDs

In simple words, temperature sensors are devices that collect data temperature from a specific source. These devices transform the information to data that can be easily deciphered by another device. Temperature sensors come in a variety of types and are used for a wide range of medical, industrial, defense, and Aerospace applications. These sensors are needed in applications where a specific temperature is required for a range of reasons from avoiding ice buildup to ensuring chemical and blood tests are run at optimal temperatures.

Variations in temperatures during certain processing applications, such as medical testing and industrial reactions, bring about significant changes in profits, quality, and safety. Several applications in industries like oil and gas, refining, petrochemical, power, pharmaceutical, etc. are affected by changes in temperature. Hence, it is important to keep a check on the temperature and monitor its changes to support smooth operations. Choosing the right temperature sensor depends upon the specific application. Please call Birk to discuss your application with one of our experienced engineers so we can guide you to the perfect sensor for your application.

RTD Vs Thermocouple Temperature Sensor

Before calling RTD (Resistance Temperature Detector) a better temperature sensor than thermocouple temperature sensor (TCs) or vice versa, it is important to first understand their respective field of features and applications. For a layman, TCs typically offer a faster response than RTD. This faster response can help keep tighter control of the process temperature.

Choose Mica Heaters for Economical Heating Solutions

Gone are the days when cumbersome heating system used to take up space in any application. Nowadays, a lot of industrial appliances make use of flexible heating systems like mica heaters for better operational efficiency. These heaters are ideal when you are looking for substrate stability and even distribution of temperature. Mica heaters must be securely clamped in place during operation.

General Features of Mica Insulated Heating Elements:

As the name suggests, these space heaters consist of elements that are covered in thin sheet of mica for insulation. Some of the characteristic features of mica heating devices are:

  • These heaters are capable of withstanding very high range of temperature (up to 600°C)
  • These heaters are very reasonable because of the low material costs
  • They can be efficiently configured in a wide range of watt densities (over 150 W/in2)
  • They are available in a large variety of sizes and shapes
  • These heaters show extremely low electrical leakage
  • They are known for fast thermal recovery
  • These heaters can be used for curved surfaces as well
  • They can be manufactured with integrated sensors and thermal switches
  • These heaters can be easily clamped on a flat surface that needs to be heated evenly
  • They are ideal for surfaces which can come in direct contact of the heater (more…)
