Emco Wheaton E2632 Parallel Loading Arm

Loading arms with vapor return lines are used for hydrocarbons (e.g. gasoline), toxic and aggressive media. Two boom loaders are connected together to form a new loader type. All movements are performed in parallel - hence the name: Parallel Arm.

Its advantages:

It can be operated like a single arm, i. e. it is highly maneuverable. Both the product and vapor recovery lines are free from pockets. By loading with the vapor return line, the product vapor will be recovered through the loading arm. This improves the profitability of the terminal because vaporized product can be recovered and vapor does not pollute the environment. By loading with a sealed manhole, a high level of protection is achieved for both the operator and the environment.

Emco Wheaton E2630 Top Loading with Vapor Return Hose

The E2630 consists of our reliable long reach loading arm combined with a hose for vapor return. By loading with a vapor return hose, the product vapor will be recovered through the loading arm. This improves the profitability of the terminal because vaporized product can be recovered and vapor does not pollute the environment. By loading with a sealed manhole, a high level of protection is achieved for both the operator and the environment.

The E2630 is the most economical solution for the loading process with vapor return. Reliable and easy handling is provided by the small weight and little offset. An E2630 may also be used where the available space is limited, e. g. existing loading stations with low roof heights.

Emco Wheaton WE2852 World Bottom Hose Loading Arm<

Our WE2852 World Bottom Hose Loader is especially designed for the bottom loading and unloading of road or rail tankers with all type of fuels. Tanker side connection is achieved with a 4“ API coupler. The loading arm dimensions are designed to cover the complete API connection area.

A bottom loading station can consist out of up to 5 product arms. The design allows unrestricted crossover of all arms. A separate loading arm for vapor recovery completes the installation. Our carbon steel swivel joint has a flame hardened ball race way to provide a long service life.

A heating cable is attached along the tubes and elbows.

The swivel joints are bridged by electric cables.

Emco Wheaton Overfill Safety Device

Our Overfill Prevention Device is a secondary safety system which prevents a product overflow, for example in the case of an incorrect pre-selected loading amount.

The electrical signal of the overfill prevention device is processed in the control system and can be used to shut off the loading process.
