UNIFLUX® Cabin Heaters

The UNIFLUX Cabin-style heater design provides the same superior heat transfer uniformity to thermally sensitive process fluids as that of the UNIFLUX Helical Coil heaters.  However it offers higher heat duty capability with the use of a multi-burner arrangement. 

The UNIFLUX Cabin heaters also are designed with finned process tubes to greatly increase tube surface and heat transfer per tube length.  The same spaced coil design is utilized in the UNIFLUX Cabin-style heater in conjunction with high velocity short flame burners.  This allows for the same flue gas flow around the process tube barrier with completely combusted flue gases as the Helical Coil design.  The spaced tube arrangement provides entrainment of cooler flue gases back into the hot flue gas jet stream for a lower overall bulk temperature, just as the Helical Coil heater design offers.  No external recirculation blower is required, as the recirculation is a forced internal recirculation by design. 

The UNIFLUX Cabin heater design is ideal for heating heat transfer fluids and specialty chemicals that may be sensitive to over temperature or fluid degradation.  Synthetic heat transfer fluids such as Therminol and Dowtherm are common application for the UNIFLUX Cabin-style heater, as well volatile gases such and Natural Gas, Hydrogen, and various chemical mixtures.  

The UNIFLUX Cabin heater can be designed with basic carbon steel process coil material up to exotic high alloy coil materials to meet the specific process requirements.  The low flux rate convection heat transfer extends the life of the heat transfer coil to provide a durable heater that will operate for decades with minimal maintenance.  All UNIFLUX heaters are completely assembled and factory tested.  Our factory tests include all control sequencing and interlock verification.  The factory testing also includes a complete burner light off and transition to main flame firing for ease of installation and minimal start-up/commissioning time.
