Parallel Loading Arm – E2632
Overview
Unlike conventional vapor recovery systems that rely on flexible hoses, the E2632 utilizes a dedicated vapor return line equipped with swivel joints. This design eliminates pockets and flow traps, preventing the accumulation of condensed vapors and reducing the risk of emissions when the loading arm is not in operation.
By loading through a sealed manhole, the E2632 helps protect operators and the environment while supporting compliance with environmental regulations and air-quality standards. The vapor recovery system also improves terminal profitability by capturing and returning product vapors that would otherwise be lost during loading operations.
Key Features
- Parallel arm design enables simultaneous product transfer and vapor recovery.
- Ideal for hydrocarbons, gasoline, chemicals, and aggressive media.
- Vapor return system captures product vapors and reduces emissions.
- Sealed loading operation enhances operator and environmental safety.
- Product and vapor lines remain free from pockets and condensate traps.
- Highly maneuverable design operates similarly to a single loading arm.
- Swivel-joint vapor line eliminates the limitations of flexible hose systems.
- Supports compliance with environmental regulations and air-quality standards.
- Optional heating capability available for both product and vapor lines.
- Piggable design available for easier cleaning and maintenance.
