Gas Cylinder Heaters – Premium Heating Jackets for Industrial and Laboratory Use

At MEILLER, we offer a premium range of gas cylinder heaters designed to meet the highest safety and performance standards in industrial and laboratory environments. These electric heating jackets are engineered for precision temperature control of pressurized gas cylinders and are available in variants certified for use in hazardous areas (ATEX zones). They ensure reliable gas flow even under high-demand conditions, making them essential in various professional applications.

Why Use a Gas Cylinder Heater?

In industrial processes or laboratories where a constant supply of gas is required, maintaining temperature stability within the gas cylinder is a critical factor. When gas is extracted from a cylinder, the internal pressure drops. As a result, the gas cools down rapidly. This can cause condensation or even freezing of moisture from the surrounding air, forming ice on the exterior of the cylinder. In more extreme cases, the gas inside can liquefy due to excessive cooling, leading to a further drop in pressure and a significantly reduced gas flow.

Gas cylinder heaters solve this problem by evenly warming the cylinder and stabilizing the gas temperature. This prevents icing, maintains consistent pressure, and ensures smooth gas delivery regardless of the withdrawal rate. Particularly with liquefied gases stored under pressure—such as carbon dioxide (CO₂), nitrogen (N₂), or propane—heating jackets are a reliable method to avoid performance loss and operational issues.

Improve Workplace Safety and Process Reliability

Using a gas cylinder heater contributes directly to workplace safety. Cold cylinders can be difficult and hazardous to handle, and a sudden drop in gas pressure due to icing may compromise the operation of equipment or lead to unexpected gas releases. By maintaining a steady temperature, gas heaters reduce these risks. Moreover, they help prevent unplanned downtime caused by inconsistent gas supply, making industrial and lab processes more efficient and reliable.

MEILLER’s heaters are designed with robust insulation and advanced safety features. Our ATEX-certified models can be safely used in explosion-hazardous environments—zones 1 and 2 (gas) as well as 21 and 22 (dust). These models include temperature sensors (PT100 Ex-i, Ex-e) for precise control and compliance with European Directive 2014/34/EU and national safety standards.

What Types of Gas Cylinder Heaters Does MEILLER Offer?

We currently offer a variety of models tailored to different cylinder sizes and operational needs. These include:

• Standard gas cylinder heaters for 230–270 mm diameter cylinders, with power outputs such as 435 W, adjustable from 0 °C to +40 °C, and equipped with digital thermostats.
• ATEX-certified heating jackets for hazardous areas, suitable for cylinder sizes:
  • Ø140 × 800 mm (approx. 10 litres)
  • Ø230 × 1400 mm (approx. 50 litres)
  • Ø318 × 1000 mm (approx. 79 litres)

Depending on the size and model, our ATEX heaters provide between 380 W and 850 W of heating power. The heating jackets can raise the gas temperature inside the cylinder up to +90 °C, while the surface temperature of the jacket itself can reach up to 200 °C. They are powered via 230 V mains voltage and can be used both indoors and outdoors, thanks to their durable and weather-resistant construction.

Application Areas of Gas Cylinder Heaters

Gas cylinder heaters from MEILLER are suitable for a broad range of industries where the temperature stability of compressed or liquefied gases is vital. These include:

• Chemical industry: For temperature-sensitive gases used in reactions or process flows.
• Food and beverage industry: Particularly for CO₂ dosing in carbonated drinks or gas-controlled packaging processes.
• Oil and gas sector: During transportation, extraction, or processing of gases.
• Welding and metal fabrication: To enhance gas flow and stability in cold working environments.
• Laboratories and research institutions: For experiments requiring precise gas temperatures.
• Environmental technology: For gas treatment in air or water purification systems.
• Agriculture: For regulated CO₂ dosing in greenhouses to stimulate plant growth.

Suitable Gases for Heating Jackets

Our gas cylinder heaters are compatible with a wide range of industrial gases, including but not limited to:

• Propane
• Butane
• Nitrogen (N₂)
• Oxygen (O₂)
• Carbon dioxide (CO₂)
• Argon

Always ensure that the selected heating jacket matches the specific gas type and meets all safety and material compatibility requirements.

How Do Gas Cylinder Heaters Work?

A gas cylinder heater functions as an electric resistance heating element. Once connected to the power supply, the jacket generates and distributes heat evenly around the cylinder wall. The design ensures that the gas inside the bottle is warmed consistently, which helps stabilize pressure and gas flow. Fastening is simple, often using hook-and-loop or buckle closures for easy installation and removal. Most models include an integrated thermostat or temperature sensor system for accurate regulation.

Are Gas Cylinder Heaters Safe?

Yes, MEILLER’s gas cylinder heaters are designed for safe and straightforward operation. When used in accordance with the user manual and installation instructions, they offer reliable temperature control without compromising safety. Our ATEX-certified models meet strict regulatory requirements and are tested for safe use in potentially explosive atmospheres. Each model includes comprehensive safety documentation, including explosion protection certificates and conformity declarations.
