Digital Control

Our system provides industry-leading digital control designed to manage all aspects of the machine to deliver smart operation. Integrated thermostat control and the ability to automatically modulate heat output and airflow based on ambient conditions provide real-world fuel and wear and tear reduction.

Portable Operation

Our highly portable configuration allows simple and easy transportation.  We use a large integrated fuel tank to provide a reliable solution for continuously rated heating requirements. Our unit has 150% fluid containment and is designed to US DOT and Transport Canada compliance. 

Green Operation 

We utilize a high-efficiency tier 4 final solution to provide reliable, low emissions operation.  Full US EPA and Environment Canada approved emissions system.   We integrate for long-term operation with oversized DEF tanks for continuous operations. 

State of the art product development program

Our design, engineering, and development team provide a diverse set of product development skills that can be put to work to meet your particular needs and requirements.   Strong mechanical design skills combine with modern electrical control systems to create equipment that provides value to all stakeholders in the path to end-use application. 

Flameless Glycol Heating

High Efficiency Operation

Our designs use proven components to provide high thermal efficiency heating solutions.  We put the heat to work and minimize waste.

  • Low heat hoarding temperature goal to reduce heat loss conditions, while always maintaining optimal temperatures in temporary hoardings

  • Utilize telematics to monitor and alarm, provide machine control as required

Bottom Line Benefit
  • Fuel consumption reductions, each ST-550 unit can burn over 2380 gal or 9000 liters of diesel per month.  Even with our high thermal efficiency design, it has a cost and emissions impact.  Using a remote thermostat lets us lean operations by matching the heat to actual heat loss requirements, that change often


Combined heat and power is a clean and efficient approach to generating electric power and useful thermal energy from the same fuel source.

Superior reliability, high efficiency, and improved air quality are some of the attributing features that have allowed an upswing in the product demand.

Great application flexibility to allow end multiple applications across several market segments
