Cooling towers are heat removal devices used to transfer processed waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove processed heat and cool the working fluid to near the wet-bulb air temperature or may rely solely on air. Common applications include cooling the circulating water used in oil refineries, chemical plants, power stations, and building cooling.

Commercial grade air purifiers are manufactured as both a small stand-alone unit and as larger units that can be affixed to an air handler unit (AHU) or to an HVAC unit found in the medical, industrial, and commercial industries.

Carbon Absorbers come in models designed for both physical and chemical adsorption of gas-phase pollutants. Adsorption involves the adhesion of pollutant gas molecules to porous solid surfaces that the contaminated air stream passes through. Physical adsorption relies on intermolecular forces while chemical adsorption involves the formation of chemical bonds. Activated Carbon Absorbers are highly efficient for removal of oil vapors, H2S and other odors, VOCs and gas phase hydrocarbons.

Air terminal units are small air handlers designed for local use and may only include an air filter, coil, and blower. These simple terminal units are called “blower coils” or “fan-coil units.” Makeup air units are larger air terminals that condition 100 percent outside air (and no re-circulated air). Air handlers designed for outdoor use, typically mounted on rooftops, is known as a “packaged unit” (PU) or “rooftop unit” (RTU).

Ionization units generate clean, healthy, fresh air by the inactivation of germs and odor molecules through oxidation or “activated oxygen.” Outdoors, activated oxygen primarily occurs in the form of positive and negative air ions and ozone. Indoors, on the other hand, air ions rarely occur. Air ionization systems “copy” the natural process of air regeneration improving indoor air quality.

Monroe custom oil/water separators are designed per American Petroleum Institute standards (API) for above and below ground installations. The basic components include an inlet section with diffusion wall, separator channel, an oil retention baffle and an outlet section. Depending on requirements, additional options can include trash screens, a slotted pipe skimmer, surface conveyors and a bottom drag or screw conveyor for solid handling.

Cartridge style dust collectors are designed to provide continuous dust collection and removal of airborne dust produced by manufacturing and processing operations at 99+% efficiency on many installations. The modular design incorporates high efficiency, pleated cartridge filters to achieve maximum filter surface area in a relatively small housing. Cartridge cleaning is accomplished by reverse compressed air pulses through a few cartridges at a time, allowing continuous operation without shut-down.

Circular Clarifiers are used for water treatment by removing undesirable chemicals, materials, and biological contaminants from contaminated water. Circular clarifiers can incorporate center or peripheral feeds. Center column supported clarifiers are available in diameters to 200 feet or more. Bridge supported clarifiers of 100 feet or more require a specially-engineered truss bridge. Circular clarifiers are available as primary, secondary, thickeners and solid-contact clarifiers.

Mounted inline in an HVAC system. These heat air as it passes over an electrically heated coil. Can be actuated remotely via BMS or locally via temperature sensor.

Direct Exhaust Extraction Systems are used by automotive repair shops to remove harmful carbon monoxide exhaust from the building while working on running vehicles. The systems utilize a hose, either spring loaded or motorized that attaches to the vehicles exhaust pipe and send the exhaust to a filtering unit to remove harmful emissions.

Waste air purification systems combine photo-oxidation and catalytic oxidation for removal of pollutants, odors and solvents. The waste air purification process is based on a technology that induces photo-oxidizing reactions to remove organic solvents and odorous substances using UVC light as the driving force in this process. A catalytic converter further increases the effectiveness of the oxidation reactions.

Dampers are designed to prevent fire and smoke from spreading from a fire source through the ventilation system and into other parts of the building. Depending on their application, fire dampers have different fire-resistance classes (called “fire-duration ratings”) and can be installed in concrete or masonry walls and in lightweight partition walls.

Analog and digital monitoring equipment for use in many applications from HVAC to water movement and control.

Industrial blowers are primarily used to exhaust foul air and replace it with fresh outside air. They are typically used for high volume, high static pressure applications to provide general ventilation in heavy-duty commercial and industrial applications including factories, warehouses, gymnasiums, underground parking garages, etc.

 Grilles, registers, diffusers and louvers are the esthetically-functional face of an HVAC system. They are available in an unlimited array of sizes, colors, controls, and configurations and can be custom-designed to suit any project. Along with standard units, specialized units are available for security and fire prevention applications, and designed with special filters for use in hospitals and laboratories.

Range vent hoods are mounted to the ceiling or wall above a stovetop cooking surface. They are typically big enough to encompass the perimeter of the stovetop surface. A hood will be made of metal, and may either be hammered, painted, enameled or otherwise finished to match the design of the kitchen.

Nuclear, biological, and chemical air filters.

Oil mist collectors are designed to collect and remove airborne oil mist, smoke and sub-micron vapors generated by operations such as high production machining and cold forming. It is a multiple stage collector that has proven capabilities exceeding 99% efficiency on many installations.

Parallel plate clarifiers have a small footprint and low space requirements and are often favored for certain applications such as dissolved metals removal. Vertical or horizontal models are available and can be incorporated with sludge thickening or oil skimming capability. Particulate settles onto the plates and slides down to the clarifier bottom. The liquid then flows into effluent channels and out of the clarifier.

Parallel plate and tube settlers are for use with clarifiers and sedimentation basins in rectangular or circular configurations. The flow in the settling zone is directed through inclined tubes or inclined parallel plates. This virtually eliminates unstable flow patterns and mixing currents which greatly inhibit the settling of solids. The inclined surfaces of the tubes or plates reduce the distance that particles need to travel before settling.

Storage tanks accumulate and store collected matter. The size of an expansion tank depends on the system pressure, collector area, system volume, and static height of the system

This safety valve releases water (thus relieving pressure) if either the temperature or pressure in a tank gets too high.

Pumps are used to move gases, liquids, or slurries. A pump displaces a volume by physical or mechanical action. Pumps fall into two major groups: positive displacement and rot dynamic.

Sand trap louvers aid in the operation of dampers manually or motor operated from the back of the louver. STLs are designed to separate debris from the air stream. STLs are generally used for ventilation applications and at the inlet duct of air handling units.

Venturi Scrubbers are designed to remove both heavy and light airborne particulate matter from industrial exhaust systems, as well as flue and process gasses. Monroe units are completely self contained and need only be connected to normal plant electrical, water and air systems. Units can be equipped with drag conveyors to remove heavy, settled particulate and oil recovery units to remove accumulated oil.
