Written by: Proformance Supply


When it comes to DEF transfer tanks for Diesel Exhaust Fluid, choosing the right equipment is crucial for efficient and reliable operations.

Blue1 Energy Equipment offers portable heated and unheated DEF Dispensing Units. We will delve into their product specifications, including dimensions, capacities, and features, while also highlighting the advantages of steel DEF tanks over alternative DEF tanks manufactured from polyethylene, specifically focusing on the TPDU-M model. Additionally, we will shed light on why Blue1 is a renowned manufacturer in the industry.

Blue1 is a trusted manufacturer of DEF transfer tanks and equipment, known for their exceptional features and benefits. The TPDU-M model from Blue1 is designed to streamline DEF handling, ensuring accurate and safe dispensing. These versatile units incorporate elements such as integrated heating systems and digital flow meters to optimize DEF handling, making the steel DEF tanks a popular choice across various industries. These units are built to last, ensuring long-term reliability and performance.

Heated Blue1 Portable DEF Dispensing Units

The heated TPDU-M model by Blue1 is specifically designed for cold weather conditions. It features an integrated heating system that prevents DEF from freezing during frigid temperatures. 

The integrated heating and insulated system features a 120 vac 475 watt heating system that is designed to prevent the diesel exhaust fluid from freezing in minimum ambient conditions down to -40⁰F (-40⁰C). The heated DEF units are available in 60 and 100 gallons.

The heating system consists of two low watt density, low profile, waterproof, pressure laminated heater pads. One heater pad is attached directly to the exterior of the polyethylene DEF Tank and the second heater pad is attached directly to the underside of the PDU Equipment Tray. The heaters are connected to an Electronic Temperature Controller that is also located on the underside of the PDU Tray. This Temperature Controller will automatically energize and de-energize both heaters based upon the ambient air temperature being monitored and measured inside of the PDU Enclosure. The entire heating system becomes functional when a 120vac power supply is plugged into the Power Receptacle on the side of the PDU enclosure. A 20 foot industrial grade extension cord is included with the system. The heating system will automatically switch on and remain switched on when the Temperature Controller is registering an ambient air temperature below 30⁰F (-1.1⁰C) inside of the PDU Enclosure. The heating system will automatically switch off and remain switched off during all time periods when the Temperature Controller is registering ambient air temperatures above 30⁰F (-1.1⁰F) inside the PDU Enclosure.

Unheated Blue1 Portable DEF Dispensing Units

The unheated DEF Transfer Tanks offer all the standard features of the TPDU-M models without the integrated heating system. It is ideal for regions with milder climates or controlled indoor environments. The dimensions of the TPDU-M model remain the same as the heated variant, ensuring easy maneuverability and convenience.
