The challenge

Leading Supplier of Liquified Petroleum Gas (LPG) in both UK and Ireland

Calor is a leading supplier and distributor liquefied petroleum gas (LPG) throughout both Ireland and the UK. The company began in 1935 and sold cylinders of butane to many rural homes.

The company expanded and grew both nationally and internationally as many industries the potential and opportunities offered by gas. In 1996, Calor was acquired by the multinational SHV Energy who today serves over 30 million customers over three continents

Protection of the Pressure Release Valve

The hood design was produced using compression moulding and was required to protect one of the most important safety features on a gas storage tank, which is the pressure release valve(s). These are used to safely discharge any excess pressures which may be caused in the event of a fire, abnormally hot weather or in case of accidental overfilling of the unit, etc.

Limit Public Access to the Valve

For safety reasons, this protective hood must be in place at all times to limit public access to these valves. It was essential for the end product to be highly durable, strong, heat and weather resistant. To ensure this level of safety, it was required to produce all hoods in a manner that could accommodate a specialised locking system which is supplied by Calor.

Tricel Solution

Tamper and Weatherproof SMC Gas Tank Hood

To protect these valves against tampering or any accidental damage, Tricel produced a custom moulded hood cap using compression moulding. These hoods are produced using sheet moulding compound (SMC) material. This is an extremely strong, durable and lightweight compound which offers excellent heat-resistant, ultraviolet (UV) and general weathering protection.

To align with fire safety precautions, SMC has low smoke and toxicity properties as well as a high chemical resistance quality. Furthermore, the material can also be colour pigmented prior to compression moulding, meaning units can be produced to any required colouring in order to match any branding requirements.

In regard to post-production painting, the compound has a low profile and low shrink characteristics which results in perfect surface appearance and ideal for painting. In this instance, Calor had requested the required hoods to be moulded and delivered in the Calor corporate green.
