DGC Dry Gas Couplings
The Dry Gas Coupling has been developed for a safe and quick connection and disconnection of hoses and loading arms to tank trucks, rail tankers and tank containers. During connection and after disconnection there is no spillage.
This increases safety in the loading process of hazardous fluids.
Suitable for handling a range of LPG applications - Propane and Butane but also for other applications with similar requirements the Dry Gas Coupling is useful.
The robust design, easy servicing and high level of security assures safe and frequent use on a long term basis. This protects the environment and the media handled, reduces the risk of accidents and saves money.
A modular design with several optional features makes it possible to find individual solutions for your special application.
APPLICATION | COUPLING SIZE |
Heavy vehicle filling | 1" |
Loading/unloading of bobtails | 2" |
Loading/unloading of tank trucks | 2"-3" |
Loading/unloading of rail cars | 3" |
Loading/unloading ship to shore | 3"-4" |
Dry Gas Couplings are used to prevent excess spillage. They protect people and property from dangerous and costly exposure by keeping hazardous liquids and vapors in-line and out of the environment.
Dry Gas Couplings are used at liquid or vapor transfer points where you do not want product loss. Using Dry Gas couplings will reduce the hazards typically found when handling/processing LPG.
The liquid release and the cost loss for 1.000.000 connections and disconnections in LPG logistics per year when 1 T LPG = 1000 $ could be :
