Preheat Introduces a New Concept in Keeping AdBlue Working in Cold Conditions

Preheat has developed and manufactured a new concept heated hose system designed specifically to keep AdBlue operational during cold weather, without the need to heat the entire storage tank.

Targeted Heating Rather Than Whole Tank Heating

This new approach focuses on maintaining flow where it matters most.

Instead of installing a full tank heater, Preheat’s solution applies controlled trace heating directly to the hose assembly. By maintaining temperature along the transfer route, AdBlue remains fluid as it moves from tank to engine, even when ambient temperatures drop.

Targeted Heating Rather Than Whole Tank Heating

Instead of installing a full tank heater, Preheat’s solution applies controlled trace heating directly to the hose assembly. By maintaining temperature along the transfer route, AdBlue remains fluid as it moves from tank to engine, even when ambient temperatures drop.

As long as the bulk volume of AdBlue is not exposed to temperatures below minus 11 degrees Celsius, there is no requirement to heat the entire tank. This targeted method significantly reduces unnecessary energy consumption.

Technical Specification

The heated hose assembly has been designed for durability and reliable winter performance and includes:

• Weather resistant outer construction
• Integrated trace heating cable
• 20 watts per metre output
• 110 volt supply
• Stainless steel reinforcement wires for added strength
• Supplied in a protective wooden crate for secure transit

This ensures the hose is robust enough for commercial and industrial environments while remaining straightforward to integrate into existing AdBlue and DEF systems.

A More Economical Alternative to Tank Heaters

Full fuel or AdBlue tank heaters involve higher initial purchasing costs and increased ongoing energy usage. In comparison, this heated hose concept provides a significantly cheaper option when measured against the cost of purchasing and installing a dedicated tank heater.

By concentrating heat only along the transfer line, operators benefit from:

• Lower capital outlay
• Reduced energy consumption
• Lower running costs
• Reliable AdBlue delivery in fluctuating winter temperatures
• Improved operational efficiency

This offers a practical and energy efficient AdBlue freeze protection solution.

Supporting DEF System Reliability

Maintaining uninterrupted DEF flow is essential for vehicles operating with Selective Catalytic Reduction systems to meet emissions standards. Preventing crystallisation within the hose assembly helps protect system integrity, reduce downtime and maintain compliance during colder months.
