Barbecuing with LPG is becoming increasingly popular. Like many other media, the propane-butane mixture carries risks. However, all barbecue enthusiasts place great importance on operating their gas BBQ safely. That\u2019s exactly what safety devices are for, such as the excess flow device. A new pressure regulator from GOK bears the label HPU, making the use of gas appliances even safer.
\n<\/p>\n

<\/span>What is the new low pressure regulator with HPU?<\/span><\/h2>\n

Unlike conventional pressure regulators for gas barbecuing, the new low pressure regulator type EN61<\/a> offers a major difference: the HPU. HPU stands for Hose Protection Unit and is a safety device that protects against unintentional gas leaks \u2013 for example, in the event of significant hose damage.<\/p>\n

The special feature of this regulator is that both pressure regulation and safety monitoring take place within a single fitting. Until now, barbecue users, campers, etc., usually had to purchase a pressure regulator and a separate excess flow device. With the new low pressure regulator type EN61 with HPU, this Hose Protection Unit takes over the function of the excess flow device.<\/p>\n

<\/span>What does HPU mean and how does it work?<\/span><\/h2>\n

As mentioned, HPU stands for Hose Protection Unit and is a different type of excess flow device. The HPU continuously monitors the connected hose line, protects against the release of unburned LPG in the event of hose damage, and automatically shuts off the gas flow if the hose is torn off or suffers a major leak.<\/p>\n

In the HPU regulator, the \u201cexcess flow device\u201d is integrated into the regulator. When correctly installed and under normal operation, the safety device (HPU) remains in a neutral position (1), which means: a ball stays in its designated position inside the regulator. This keeps the gas supply open.<\/p>\n

\"The<\/a>
The operating principle of the Hose Protection Unit is quite simple, yet highly effective!<\/figcaption><\/figure>\n

If the hose line becomes damaged, a higher flow rate is generated, triggering the safety device \u2013 in other words, the ball moves from its original position. The ball blocks the regulator\u2019s outlet (2). This interrupts the gas flow and prevents any further gas from escaping.<\/p>\n

<\/span>When is an excess flow device mandatory?<\/span><\/h2>\n

In private use, an excess flow device must be used if the hose length exceeds 150 centimetres. This requirement is specified in the DVGW worksheet G 612 (A). For commercial users, the use of an excess flow device is mandatory when the hose length exceeds 40 cm.<\/p>\n

<\/span>Is the HPU something entirely new?<\/span><\/h2>\n

No, the HPU itself is not entirely new in GOK\u2019s range of pressure regulators. There are already regulators with the same safety technology, although these have not previously been labelled with the \u201cHPU\u201d designation.<\/p>\n

Essentially, the HPU fulfils the same function as a conventional excess flow device. This is known to most as a retrofit single component, but it has also existed for quite some time as an integral part of established pressure regulators.<\/p>\n

For example, the pressure regulator designated type EN-61 DS<\/a> for outdoor use is available both with and without an integrated excess flow device. It also features an overpressure shut-off device S2SR (OPSO) to protect the gas appliances from excessive pressure. This combination represents the highest level of safety for pressure regulators used in small cylinder systems (such as 5 or 11 kilogram cylinders) outdoors.<\/p>\n

<\/span>Why do I need a pressure regulator for a gas barbecue?<\/span><\/h2>\n
\"Basic<\/a>
Basic requirements for a functioning gas barbecue: gas cylinder, pressure regulator, and hose line!<\/figcaption><\/figure>\n

A regulator ensures that the pressure from the gas cylinder reaches the barbecue at a consistent and usable level. If the gas appliance does not receive a constant pressure, this can lead to malfunctions and, as a result, poor grilling performance. In addition, some pressure regulators are equipped with special safety devices such as an excess flow device or overpressure shut-off. These protect the connected appliances and nearby individuals in the event of an incident.<\/p>\n

<\/span>How should I store gas cylinders for the barbecue?<\/span><\/h2>\n

Gas cylinders are not permitted to be stored or used just anywhere. Outdoor use is generally always unproblematic, and for gas barbecues, the cylinder may remain permanently in the cabinet beneath the unit.<\/p>\n

However, under no circumstances should the cylinder be stored in places like a cellar or a bedroom. More information about proper storage can be found in this video:<\/p>\n
