Hot Tube Features

Industrial duty panel with NEMA 4 rated enclosure. Operational controls include PLC controller, touch panel dsplay and operator interface, heat exchanger temperature monitor, high/low level controls, tank fluid temperature sensor. Panel also utilizes a standard safety disconnect and red flashing warning beacon. Optional features may include-- digital read out and controls for overspray foam control, other NEMA ratings, remote panels, PLC automation.

Polished, large diameter, tubular 10 gauge, 316L stainless steel standard construction (other alloys available), reducing diameter over tube length to maintain scrubbing velocity for high efficiency. Tig welded, tuned for high heat transfer efficiency and designed for ease of cleaning and tank bottom access. Exiting tube section is shrouded to prevent fluid surface fouling.

Extended length burner tube to provide a greater square feet of heat transfer surface. This results in lower stack temperature, more efficient utilization of energy and increased evaporation capacity, as much as 50% higher than normally advertised rates within the same footprint. Energy consumption per gallon evaporated is reduced by up to 20% with the addition of this option. Wastewater analysis must be performed to qualify application. Available on E-300 and larger models.

The entire unit, both interior and exterior, including all wetted internal parts are constructed of polished stainless steel. Polished stainless steel outer skin, when propely maintained, looks like new indefinitely. Standard construction for all units - - 10 gauge (.140”) grade 316L stainless steel - offers excellent resistance to a wide range of corrosives and atmospheric exposures, high temperature strength. All sides are insulated with 2” fiberglass, 800°F rated. Tank bottom is sloped to 4” flange clean out port for easy solids evacuation. Alloy recommendation does not express or imply any warranties offered against material corrosion.

• AL6XN - 6% molybdenum super austenitic alloy for better chloride resistance without the expense of high nickel alloys. • High nickel alloys - such as B-2, C-22, G-30, 20Cb-3 for a wide range of specific corrosive applications. • Hastelloy C-276 - one of the more universally corrosion resistant alloys with excellent high chloride resistance and high temperature properties.

Two-in-one double wall stack connection to evaporate effluents (see stack description).

A safety cage surrounds the blower, blower motor, drive belt, and stack. This protects personnel from heated and moving parts.

Designed specifically for evaporated vapor exhaust. This blower features an all stainless steel impeller with 5 year warranty. The impeller is self- cleaning backward inclined radial blade design that is electronically balanced for long continuous duty. It is belt driven with self-adjusting belt tensioner and speed variable depending on model application. Two heavy duty, greasable pillow block bearings are utilized. The blower housing is all heavy gauge, tig welded, stainless steel construction for long life.

With exhaust air inlet - keeps lid cool to the touch. Lid is counter- weighted for operator safety.

Located at the inlet to the water vapor exhaust blower to capture droplets that might be drawn up the stack. This is to minimize carry over of oils or particulate to the atmosphere. It is easily removed for cleaning or replacement when dirty. High density mist eliminator pads are also available for capturing 10 micro particulate.

The oil skimming weir drains through a 2” port located at the right height for a barrel, or piping can be easily installed to direct the oil to a destination. The flat sloped bottom is designed for easy cleaning. No complicated bottom geometry to create cleaning problems.

The 4” NPT clean out port is located at the low point of the flat, sloped bottom for easy clean out. Both the oil skimming weir and clean out port may be connected to the skimmer sludge pump option with the 2” NPT reducer provided.

Redundancy level control is achieved by the use of a stainless steel lever-arm float valve assembly and a high/low level float switch assembly. The float valve assembly provides stable continuous feed into the evaporator, while the high/low level float switch monitors fluid level extremes and will shut down the burner, feed pump and indicate an alarm fault condition. Surface operating floats ignore foam and are not affected by fouling fluid concentrations or temperatures. The level switch also allows for fill control upon start up and auto restart.
