Liquid Control & Tanker Loading Specialists

Tank Truck Systems

Emco Wheaton are world leaders in the design and manufacture of tank truck equipment. All components are designed to operate reliably in hazardous conditions, ensuring that your product is delivered without spillage or contamination, at all times protecting the driver and the environment. The systems are tailored to fit into many operations, vehicles and bulk plant requirements. Their equipment complies with many industry standards and recommended practices, including ISO 9000/2000 approval, ensuring that methods and manufacturing procedures are monitored consistently, resulting in quality approved equipment time after time.

Air Control Systems

We specialize in providing standard and customized Air Control Systems for remote operation of tank truck equipment such as air operated Emergency Valves, Vapor Vents etc.

Sequenced air systems provide a clean, safe, reliable and easy to use system for the delivery of petroleum products. They are specifically designed to cope with today's harsh environment in hazardous transportation.

Benefits include:

  • Minimizes operator error during loading and unloading
  • Maximizes system flow rates to increase fleet efficiency and profitability
  • Replaces cable operated equipment which reduces maintenance costs
  • Ensures that valves are open and closed fully every time for high flow and increased safety
  • Reliable operation in cold weather applications
  • Reduces costly tank repairs to reversed bulkheads

Bottom Loading and Vapor Recovery System (BLVR)

The advantages of bottom loading are well proven, with most oil companies having standardized on the practice internationally.

The benefits of a Vapor Recovery System are that it is safer, faster, cleaner and provides the ability for vapor return, vapor reduction, cost reduction, and closed filling.

Our Bottom Loading Systems usually include Vapor Return facilities at little extra cost.

Vapor recovery is achieved by including a hood on the compartment vent valve and a Vapor Recovery Adaptor at the end of the vapor return pipe. The facility can be utilized for both stage 1A vapor recovery (recovery of vapors whilst loading) and stage 1B (whilst off-loading).

Particular attention has been given to low pressure drop in the design of this equipment. When installed correctly, zero vapor emission can be achieved..

Data Plus Electronic Pump Metering System (EPMS)

Our latest generation Data Plus Electronic Pump Metering System (EPMS) utilizes sophisticated electronic control technology together with proven engineered components creating an integrated pump metering solution which delivers intuitive, user-friendly operation.

The new modular system incorporates an intuitive, easy to use large screen display enabling the operator to easily control the metering system through the Display Key Pad.

Features include:

  • Intuitive Operation - large display with text prompts to guide the operator through the metering process
  • Multi-Fuel Calibration - can be calibrated from the keyboard to meter for up to five fuels with different viscosities
  • Simple Installation - The gas separator is integral to the manifold reducing both weight and installation time
  • Modular Design - the system is modular, allowing for future upgrades:
    • Data transfer module
    • Compartment volume monitoring module
    • Temperature compensation module
    • GPS coordinates module
    • Remote control module

Manifold Valve System

Our Manifold Assemblies are supplied in fully assembled form for easy installation, allowing any compartment to be pumped or metered for bulk or hose reel delivery in a clean, safe and simple manner.

Each assembly comprises, for each compartment; our API adaptors and pneumatic manifold valves, a lightweight manifold, fabricated from extruded aluminum, and a guard bar that is interlocked to the vehicle brake system.

Product return system for safe and clean return of product to an appropriate compartment can be included as an optional extra. This feature is used when a multi-compartment tanker, carrying different products, is changing the type of product being delivered through a hose reel and the hose and manifold need clearing to avoid contamination.

Benefits of manifold systems:

  • Improves driver productivity
  • Eliminates the use of dry-break connectors and heavy jumper hoses
  • Reduces cross-over errors
  • Lower weight and envelope size compared to other piping systems
  • Product Return facility for 100% product retention

Sealed Cargo System (SCS)

As energy prices continue to increase and product loss problems continue to grow, active monitoring of bulk petroleum transport is becoming a necessary requirement.

Utilizing proven Radio Frequency Identification (RFID) technology, our wireless Sealed Cargo System (SCS) for fuel road tankers provides operators a unique and accurate way to monitor individual compartment valves and hatches, give instant alerts and real time tracking from loading terminal to delivery point to a host computer or mobile phone.

The system is upgradeable to include wet leg (liquid presence) sensing and geo-fencing i.e. a complete sealed delivery system (SDS) that can replace and add much more than our successful hard wired, onboard SDS which, has been the preferred solution for many years.

Sealed Delivery System (SDS)

Our hard wired, ATEX certified, electronic Sealed Delivery System (SDS) provides electronic load sealing integrity. It also makes available the means to reduce vapor loss and eliminate tank top dipping.

SDS utilizes electronic sensing technology together with proven engineered components to create an integrated, on-board electronic sealing solution.

The SDS API Adapter working in union with the pneumatic Emergency Valve, Manifold Valves and optionally with Manhole Cover sensors provides an electronic seal for individual tanker compartments, recording any movement and wet/dry status between loading and discharge.

A combination of wet leg (liquid presence) and valve sensing are digitally processed and recorded to provide a complete Sealed Delivery System with clear individual tanker compartment status.
