The three models of the HBG-HBE conventional evaporators process wastewater at rates of 8, 15, and 30 gallons per hour. The natural gas-heated HBG systems have two models. The all-electric HBE, featuring eight 2600W coil-type elements, has one model with either 230V 3ph or 460V 3ph configurations. All of the units are made of heavyduty steel, insulated and double lined for energy efficiency and safety. The HBG models feature our unique combustion chamber design, which uses advanced heat reflective material to reflect the heat directly onto the underside of the evaporation tank floor for super-efficient energy usage.

A variety of redundant systems insure the safety of the operator. For instance:

• A high-limit thermo-couple turns off the unit before the tank can be damaged by scorching;

• Two stainless steel floats provide high-low water level protection by shutting off the unit when the wastewater level rises or lowers excessively;

• A third float provides redundant or backup protection.

• With the motor and bearings set off from the heat and steam path, the Built-in Exhaust Fan minimizes exposure to moisture for increased bearing life.

• High quality, energy-efficient Burner uses natural gas or propane fuel in a custom-designed, highefficiency combustion chamber.

• Made of high-density ceramic refractory fiber, the Combustion Chamber features a unique energy-efficient design for reflecting the heat directly onto the floor of the evaporation tank for energy savings. A key element of the unique design is the use of Combustion Chamber Baffles, which reflect the heat upward.

• Adjustable Feet for convenient leveling of equipment.

• A High-Temperature Safety Shutoff turns unit off before the tank can be damaged by scorching.

• A 3-inch Recessed Drain Port is positioned below the tank floor for easy disposal of sludge.

• Dual, insulated, double-walled Locking Lids have easy-grip, insulated handles and provide quick and thorough access to tank while protecting the operator.

• Optional Wastewater auto fill uses a heavy-duty, poly airdiaphragm pump to automatically refill the tank upon demand for continuous operation.

• Nema 4 fiberglass enclosure makes a water-tight Control Box featuring conveniently positioned Hour Meter, Operational Indicator Lights, manual reset high temperature Cutout Switch, and Other Switches for exhaust fan, burner, auto fill pump, and foam suppression system. The side panel includes Troubleshooting Indicator Lights and a Batch Counter, which monitors the wastewater concentration level and automatically shuts down the system when full concentration level is achieved.

• All Models Certified to the UL-795 SAFETY STANDARDS OSHA Compliant

• Heavy-duty Evaporation Tank is made of carbon steel with optional alloy upgrades to 316L or AL-6XN stainless steel for added corrosion resistance.

• The top cover and exhaust stack are made of Corrosion-Resistant Stainless Steel for extra-long life in harsh environments.

• Two stainless steel float switches with magnetic controls provide reliable Low- and High-Water Shut Off preventing the unit from overflowing or scorching the tank floor, as well as accommodating the optional automatic refill feature for continuous operation; a third Float Switch backs up the high level as redundant overflow protection.
