Gas Heater for Carbon Dioxide

When CO2 decompresses a cooling effect occurs resulting the gas output to stop operating consistently. A CO2 gas heater is required for some high flow applications to prevent the regulator from failing due to freezing. One of the major causes of a regulator freezing is gas flow in excess of its capacity in addition to other environmental factors described below.

Conditions which many effect the gas temperature include;

  1. Speed of gas flow
  2. Ambient temperature
  3. Type of carbon dioxide or CO2 Mixture
  4. Initial temperature of carbon dioxide

This issue is may occur in high flow environments such as breweries and stadiums. By appropriately preheating the carbon dioxide gas prior to the regulator, freezing can be prevented.


High Pressure
Medium Flow CO2 Gas Heater

The medium flow carbon dioxide preheaters are suitable for pressures up to 200 bar (20,000 kPa).

The CO2 flowing through the system are evenly warmed through an automatic temperature control, so that an uninterrupted flow – even when in constant use – is provided. There are two mounting options available.

One has type 30 connections and can be mounted between the cylinder and the regulator, or on a wall mounted manifold arrangement, between the manifold and regulator. The second type has female to male threaded connections and can be installed as part of a manifold “system”. Gas warmers should be situated under cover as the units are weather proof but not waterproof. It is recommended that the power is disconnected when the system is out of use for long periods as the gas heater can overheat the gas. When the system is not being used the cylinder valve should be shut and the gas pressure released from the system.

High Pressure
High Flow CO2 Gas Preheater

The high flow carbon dioxide preheaters are suitable for pressures up to 300 bar (30,000 kPa).

Our gas heaters are manufactured to the latest VDE-CE regulations and DIN/EN 60335-1. The CO2 flowing through the system is evenly warmed through an automatic temperature control, so that an uninterrupted flow – even when in constant use – is provided.

The CO2 heater should be mounted between the cylinder and the regulator, ideally on a wall mounted manifold arrangement. It should be situated under cover as the units are weather proof but not waterproof. It is recommended that the power is disconnected when the system is out of use for long periods as the gas heater can overheat the gas. When the system is not being used the cylinder valve should be shut and the gas pressure released from the system.
