BLOWER GUARD
A safety cage surrounds the blower, blower motor, drive belt, and stack. This protects personnel from heated and moving parts.
CONTROL PANEL
Industrial duty panel with with NEMA 4 rating. Standard safety disconnect, red flashing warning beacon, all controls and indicators for operation, manual reset button, digital temperature controllers monitor fluid and heat exchanger. Optional features may include-- digital read out and controls for over-spray foam control, other NEMA ratings, remote panels, PLC automation.
SIDE MOUNTED HEATING ELEMENTS
Heating elements mounted externally to the tank for safety and long life. Heating elements never contact wastewater solution. Heating elements are rigid clamp mounted to the sides of the tank to preclude insulating effect of settled particulate. This location maintains high efficiency and prevents overheating and failure of heating elements. High density, foil back insulation prevents heat loss to surrounding environment. Thermo- couple protected elements to monitor and report on operation and incorporating system shut down if tempera- ture limits are exceeded.
TANK
The entire unit, both interior and exterior, including all wetted internal parts are con- structed of polished stainless steel. Standard construction for all units -- 10 gauge (.140”) grade 316L stainless steel - best corrosion resistance of the standard stainless steels, high temperature strength. All sides are insulated with 2” fiberglass, 850°F rated. Construction options include -- AL6XN, Hastelloy C-276, and other high nickel alloys for almost any application. Alloy recommendation does not express or imply any warranties offered against material corrosion.
TANK CONSTRUCTION OPTIONS
  • AL6XN - 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 temperature properties.
ACCESS LID
With exhaust air inlet - keeps lid cool to the touch. Lid is counter- weighted for operator safety.
EXHAUST BLOWER
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.
OIL SKIMMING WEIR
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.
CLEAN OUT PORT
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.
COALESCING FILTER
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.
TRANSFER PUMP SYSTEM
Fluid level control is maintained by a float operated ball valve. The air operated transfer pump pumps fluid from a storage tank to the evaporator. When the fluid level is low in the evaporator, the pump forces fluid through the valve, as the fluid level rises the float ball rises on the surface of the fluid closing the valve. When the tank is full, the air pump stalls against the closed valve. Fluid level, by this method, is maintained at a constant level without larger volumes of wastewater introduced to the evaporator to cool and upset the fluid already in the tank. This results in efficient steady state operation. (Optional on E-100)
LEVEL CONTROLS
Redundancy level control is achieved by the use of a stainless steel lever-arm float valve assembly and a high/low level (low level only on E-100 without transfer pump) float switch assem- bly. 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.

EXHAUST STACK
(recommended) Single walled stack used to exhaust water vapor to the atmosphere. Stainless steel stacks bolt together in five (5) foot sections with die cut gaskets.

OVERSPRAY FOAM CONTROL SYSTEM
(optional) Electric operated centrifugal pump that recirculates fluid from the evaporator and sprays it over the surface of the liquid waste. This helps to break up surface tension and allows the water to evaporate through any surface film. It also exposes more surface area to the air being pulled across the surface of the fluid assisting in the evaporation rate. Foam sensor operates in the area above the normal operating fluid level and detects foaming conditions as they occur in the tank. This sensor then activates the overspray system. All components, pump, strainers, nozzles, valves, piping, and controls are included. 316 stainless steel for all wetted parts.

HOLDING TANK
HDPE, polypropylene, steel, or stainless steel. Many standard and custom engineered designs and sizes available. Connections, sight glass, manways, control interface, stainers, skimmers, and valves to suit requirements.

ANTI-FOAM DISPENSER
The chemical feed pump will automatically add the anit-foam agent to the waste solution in the evaporator. It operates in conjunction with a foam sensor that detects the presence of foam in the space above the normal operating fluid level in the evaporator tank.

ODOR CONTROL
A pneumatic dispenser releases an atomized chemical adsorbent from a strategic location into the evaporator air stream. Calibrated metering and available electric timer controls allow for tailoring to specific requirements.

SPECIAL APPLICATION, PLC CONTROLS
Remote operating controls or remote telemetry. Consult factory for special automation and monitoring requirements or specific types.

REMOTE TANK SENSING SYSTEM
The feed tank that supplies the evaporator also works as a settling tank and an oil separator tank. Pumping separated sludge or oil to the evaporator will reduce overall efficiencies and require more operator and maintenance time. 1) The feed tank can be set up with sensors to determine oil and sludge layers and permit pumping only aqueous wastes to the evaporator. 2) The feed tank can be set up with level controls to determine presence of fluid and shut down or restart the evaporator according to demand.

PUMP DIAPHRAGMS
Standard transfer pump diaphragm is Santoprene. Other available pumps include Neoprene, Buna N, Viton, T.F.E. (Teflon) with urethane, E.P.R., and Polyurethane.

SKIMMER SLUDGE PUMP SYSTEM
(optional) Transfer and removal of skimmed oils and evaporator residue. Air operated diaphragm pump, 2” NPT, plumbed into clean out and oil skimming weir, all piping and valves for easy operation. Available as 1) aluminum housing, black iron pipe and bronze ball valves; 2) cast iron housing, black iron pipe and stainless ball valves; or 3) stainless steel housing, pipe and ball valves. 1” NPT pumps available for light duty applications. Manual and automated systems available.

REMOTE FLUID LEVEL SENSOR AND CONTROLS
(optional) Adjustable remote level float switch can be tether mounted in any type of waste-water storage vessel and connects to the evaporator control circuit to shut down the evaporator when wastewater supply is depleted and then restart the evaporator when the wastewater supply is replenished. This option requires that the transfer pump and controls are opera- tional.

WATER VAPOR RECOVERY CONDENSER
Condenser will recover the water vapor coming off the evaporator. Each applica- tion is individually assessed to determine correct type of condenser based upon flow rate off the evaporator and the availability of cooling medium for the condenser. The water may then be recycled within your facility. Requires cooling medium and may increase your operational costs. We will help you closely assess your needs for this option.

REDUNDANT (BACK-UP) LEVEL CONTROLS
Secondary high and low level control assembly, to be installed as a back-up to the primary high/low level controls. Back-up assembly may be either the same type as the primary (float actuated microswitches) conductivity type or frequency shift sensors.

INSTALLATION
Installation by factory service technicians or local authorized contractors.

MISCELLANEOUS
Modification of standard equipment for special processes.
