Hot Tube Optional Equipment

(recommended) Stack within a stack that exhausts water vapor through the inner stack and the burner exhaust through the outer stack, venting to the outside atmosphere. This prevents water vapor from condensing and drifting. Stacks bolt together in five (5) foot sections with die cut high temperature gaskets. Double wall stacks also help minimize odors that may be created when exhaust gases are combined with water vapor.

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. Assembly is stainless steel for all wetted parts.

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 available to suit specific requirements.

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.

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.

Remote operating controls or remote telemetry. Consult factory for special automation and monitoring requirements or specific types.

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.

Burner controls and gas train set up to comply with F.M. requirements. Standard on larger models.

Burner controls and gas train set up to comply with I.R.I. requirements.

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.

(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.

(optional) Adjustable remote level float switch can be tether mounted in any type of wastewater 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 operational.

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.

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.

Combination gas/oil air atomizing burner and modifications to combustion chamber to accomodate the burning of various oils in the evaporator as fuel. Offers versatility in erergy sources. Waste oils must meet certain qualification require- ments. This option available only on E-600 and larger models.

Installed in the gas line to control the volume of fuel entering the burner. This controls the heat input, the boiling, and the rate of evaporation within the unit. It can also be connected to the foam sensor to control foaming. This option available only on XLT and E-900 and larger models.

Installation by factory service technicians or local authorized contractors.

Modification of standard equipment for special processes.
