Choose safety, choose cost saving, choose time saving

To help you be compliant with IMO SOLAS FSS Code & ISO14520 for fixed gaseous fire extinguishing systems and NFPA 12 codes, look no further. (Scroll down for details.) Our unique place in the monitoring of liquefied gaseous extinguishing systems is that we cross-verify liquid level contents with agent mass calculations in a unique Portalevel™ MAX –Portasteele™ Calculator combination which has never been done before. We are launching a new remote constant monitoring system too – Permalevel™.



ISO 14520-1:2015 (Gaseous fire-extinguishing systems – Physical properties and system design – Part 1: General requirements)

Chapter 9.2 Inspection, 9.2.1 General The storage container contents shall be checked every 6 months as follows: Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5% or a loss of pressure (adjusted for temperature) of more than 10%, it shall be refilled or replaced

Annex F – System Performance Verification Every 6 months: perform the following checks and inspections: for liquefied gases, check weight or use a liquid level indicator to verify correct content of containers; replacer or refill any showing a loss of more than 5%


NFPA 2001:2018 (Standard on Clean Agent Fire Extinguishing Systems)

Chapter 8 Inspection, Servicing, Testing, Maintenance, and Training – Clause 8.3 Semiannual Service and Inspection. At least semi-annually, the agent quantity and pressure of refillable containers shall be checked – Clause 8.3.2 and 8.3.3 For halocarbon agent containers with / without a means of pressure indication, if a container shows a loss in agent quantity of more than 5%, it shall be refilled or replaced
