Additive Injection System | Additive System

Additives are designed to increase the efficiency of home heating oil. They also protect heating oil boilers and prolong the working life of an oil storage tank. Our additive system can be retrofitted in both the DataPlus MKII 400 pumping system and the DataPlus MKII 800 pumping system as well as competitor systems or a non-metering system.

• Fewer build-ups of carbon and sludge
• Improved system performance
• Stabilises fuel
• Keeps fuel fresher for longer
• Fewer servicing issues

The system consists of a dosing chamber and bracket, two or more capacity chambers, bottle adapter, an additive injection valve, chemical-resistant hydraulic hose and hose unit, and a control system depending on the application.

Unlike competing systems that opt for injection on the vacuum side, EMCO Wheaton’s design adds 100ml of solution per system cycle through a valve that’s located after the meter. This is done to guarantee accurate fuel delivery and avoid discrepancies that can add up over time. Delivery is initiated and controlled by either an electronic litre counter display or a manual pneumatic control unit.

The valve is based on the Venturi effect. When deliveries do not require additive, the system remains in an ‘open’ state with no restriction to flow. Flow rate will only drop temporarily at the point when an operator adds solution to the mix – this last roughly six seconds. Once complete the valve opens again so flow can continue unimpeded.

In line with health and safety recommendations from COSHH, EMCO Wheaton’s additive system can also incorporate an adapter unit to limit operator contact with the solution. For larger bulk deliveries, the additive system offers a 20-litre storage tank option. Smaller jobs can be completed with our capacity chambers in 1.2-litre and 3-litre containers.

The system is designed to operate between -20°C to +50°C and has a total kit weight of 18kg. EMCO Wheaton supplies all the necessary bracketry for installation.

The dosing chamber will introduce 100ml of additive for every 500 litres of fuel. This is done at the beginning to ensure a good mix of solution throughout, even when delivering larger quantities.

This product is designed to be durable and has few moving parts.

However, fuel delivery is an intensive process and equipment occasionally requires maintenance to remain in optimal condition.

That’s why EMCO Wheaton has a team of expert service engineers on hand to troubleshoot any problems you may have. Simply call the support line to speak with a member of the team.
