Heat Transfer Fluid Heaters

Heat Transfer Fluid Heaters

The unique convective heat transfer design of the Uniflux ® fluid heater eliminates the possibility of flame impingement on the process tubes and provides a completely uniform flux density around the periphery of each tube. This uniform heat flux reduces fluid degradation and prolongs the life of the heat transfer fluid. Shop assembled with all controls and instrumentation for automatic, safe and reliable operation.
