LPG Camper Tanks for Campers, Caravans and Food Trucks

This article provides a comprehensive guide on the use, installation, and safety aspects of LPG Camper Tanks in recreational vehicles, in accordance with European standard EN 1949 and the Dutch NPR-2577 guideline.

Introduction: LPG/Gas in Your Vehicle

For LPG applications in your camper, caravan, or food truck - for example for cooking, heating, or other purposes - an LPG Camper Tank offers a professional solution. As an alternative, you might consider using refillable gas bottles.

Operation of LPG Gas Storage in Camper Tanks

Basic Principle

LPG is stored in liquid form in the LPG Camper Tank. A small portion continuously evaporates and collects in the upper space of the tank. The gas is withdrawn from this vapor phase, leaving the tank in gaseous form.

Evaporation Process and Temperature Dependence

The evaporation process requires heat extraction from the environment. Propane evaporates better at low temperatures than butane. Therefore:

1. Pressure in the tank is highly temperature dependent
2. Pressure may drop during high consumption in cold conditions
3. Consider an additional gas bottle for more evaporation capacity with high demand

Tank Outlet Connection Types

Connection Specifications

Type Approvals and Inspection Requirements

LPG Camper Tanks are equipped with 67R-01 EU approval, a strict standard for automotive LPG applications. These tanks are not subject to a 10-year recertification but do require annual visual inspection for:

1. Rust formation
2. Damage
3. Deformations

Mounting of LPG Camper Tanks According to NPR-2577

Safety Requirements

The mounting must resist forces during normal use and in collisions. The NPR-2577 guideline specifies:

Available Mounting Systems

1. Tank Frame with Tension Straps - For universal application
2. Mounting Rings - For welding to angle iron constructions
3. Mounting Brackets - With foot mounting to the vehicle

Positioning and Orientation

Note the marking on the tank indicating the horizontal center plane and the top. The appendages should be slightly downward facing.

Essential Safety Guidelines for Installation

Filling Systems and Connections

External Fill Connections

Various types available:

1. Recessed fill connections with fill pot
2. Flat fillers with bayonet nipple
3. Mini fillers for compact spaces

Electrical Safety Systems

Electric Tank Valves

Provide easy operation from the cabin but consume approximately 11W (1A) at 12V.

Safety Circuits

1. Relay circuit that closes when ignition is switched off
2. Impact switch (Fuel Cut Off Switch) for collisions
