Halon-replacement fire-extinguishing gases — FM200 (HFC-227ea) and NOVEC 1230 — are modern alternatives to banned halon systems: they are extremely effective as gaseous fire extinguishing agents, whilst having a significantly lower environmental impact. PWENT offers a complete range of transfer equipment: for the maintenance, charging, recovery and recycling of FM200 and NOVEC fire suppression systems. Note: 400-030 covers the focus on fire protection maintenance. Industrial-scale FM200/Novec charging systems are a separate category (500-030).

Halon-substitute fire-extinguishing gases — background
The Montreal Protocol has phased out the use of halon fire-extinguishing gases due to their ozone-depleting effects. The halon substitutes FM200 and NOVEC fire-suppression gases match the effectiveness of halon, but do not damage the ozone layer (ODP = 0) and have a much lower GWP. Their maintenance requires specialised equipment: the gases must be handled in a closed system, and release into the atmosphere is prohibited.

Product THB/523
The PWENT THB/523 transfer unit is a professional system designed for the charging, recovery and recycling of halon-replacement fire-suppression gases (FM200, NOVEC). Operating pressure: 70 bar. Closed system: the gas does not enter the atmosphere during maintenance. Filtration and separation: contaminants can be removed from the used gas, making it suitable for reuse. This is not only critical from an environmental perspective, but also economically — FM200 and NOVEC extinguishing gases are expensive, and recycling results in significant cost savings.

Inert shielding gases
Mixtures of inert fire-extinguishing gases (IG-541, IG-100, IG-55) (nitrogen, argon, CO₂). Their maintenance is covered in category 400-035 (shared physical URL). Some equipment is suitable for handling both halon substitutes and inert gases.

Our staff will help you choose the right transfer machine based on the type and capacity of your existing vaccination system.
