As local authorities continue to award longer-term contracts, road-lining companies are facing increased pressure to reduce their costs and are therefore seeking new equipment solutions that can enable greater efficiencies. The Calor refillable gas system will save you money, reduce health and safety risks, and significantly speed up refilling. It’s so good, it even has the seal of approval from the RSMA.

Calor's refillable gas system

Selecting a suitable system

Our refillable LPG systems comprise typically of a four-pack cylinder arrangement, which remains on the vehicle.

The vapour off-take cylinders are fitted with a valve arrangement that enables operatives to refill them safely, in situ, via a high-speed electric pump attached to a bulk LPG tank located at the depot.

Reducing manual handling

A refillable system removes any manual handling concerns as cylinders can be topped up easily and conveniently on the vehicle at the bulk filling station, achieving significant efficiency improvements in the speed and ease of refilling.


To help raise safety standards in the industry further and to help operators demonstrate the competency of their operators using LPG systems, Calor provides comprehensive on-site training ensuring personnel are familiar with the properties of LPG and can understand and demonstrate the correct process for safe refilling.

Requirements for easy refueling

A refillable LPG cylinder system is purpose-designed to make refueling as quick and simple as possible. To ensure the process is carried out safely, efficiently and in accordance with relevant legislation, there are a few basic rules to bear in mind.

  • First, the LPG bulk tank, its associated equipment and the cylinders must be sited correctly to keep them safe from potential hazards such as excessive heat or their proximity to hot surfaces.
  • Second, and as a requirement of the Dangerous Substances and Explosive Atmosphere Regulations (DSEAR), it is important that the area around the bulk tanks and any equipment in the vicinity is free from ignition risks during LPG transfer.
  • Specifically, the vehicle should be parked with the engine switched off, at least three metres from the LPG bulk vessels, with all burners and pilots turned off.
  • Signage should be unobstructed and clearly visible within the area of the bulk tanks, forbidding smoking and the use of mobile phones or reminding of the dangers of other ignition sources.
  • All persons filling should be trained and appropriate PPE including overalls, safety footwear, goggles/visor and LPG resistant gloves/gauntlets worn at all times during the refilling process
