Bag Filters. A sediment filter that is frequently used for dust removal. They are surface filters that block particles on the filter’s surface. Air flow can be from outside to inside the filter or visa versa, depending on the application. Bag filters are usually not designed for replacement when clogged, but can be cleaned by mechanical shaking or by backwashing with compressed ai

Automated Ball Valve: The same as a manual ball valve (see above), except the valve mechanism is moved by an electric, pneumatic, or hydraulic motor which is controlled by a remote switch or remotely generated electronic signal.

  • SPEC #: 17900


Manual Ball Valve: A valve that is opened and closed by turning a handle attached to a ball inside the valve. The ball has a hole through the middle. Flow occurs when the hole is in line with both ends of the valve and stops when it is perpendicular to the ends of the valve. The handle is in line with the hole through the ball. Because the motion of the handle between the OFF and ON position is 90 degrees, the valve is classified as a quarter turn valve.

Batch Agitated Pan

Batch Agitated Pan Dryers. Pan dryers consists of a circular, pressure-rated vessel with a flat or conical-shaped bottom. An agitator, often heated, can be bottom mounted or top mounted. Top mounting is preferred for most pharmaceutical applications because it eliminates dead spots where product can accumulate. The vessel top head, sidewall, and base are provided with a heated jacket to reducing the likelihood of solvent condensing on these surfaces during the drying operation. The top-mounted agitator is provided with both rotational and up and down movement. The agitator for a pan dryer provides good mixing and efficient contact between the product and the heated vessel surfaces, including the agitator itself. The agitator also helps discharge dried solids. A large nozzle, mounted on the sidewall, is opened, and the agitator arms push product through the opening whenever they pass by it.

Biopharmaceutical Biokill, Liquid Waste Decontamination System. Biokill is effectively sterilization used to destroy all microorganisms including large numbers of bacterial spores. Heat treatment is most effective for sterilizing wastewater that contains high levels of solids. These systems usually have tanks where wastewater is treated at temperatures and pressures typical of autoclaves. Autoclaves may be used for treating small quantities of liquid wastes in laboratories. Large animal facilities and those with high numbers of small animals may require large centralized wastewater treatment systems. Heat treatment systems can also include grinders, storage tanks, and heat recovery systems. Chemical treatment systems can be used successfully in some applications, although they are not as effective in treating wastewater from animal facilities because of potential interference with chemical disinfection by solids in the wastewater.

Biological Safety Cabinets

Biological Safety Cabinets. These cabinets, also called Laminar Flow Biological Safety Cabinets, combine product, operator and environmental protection. They were developed to provide protection from diverse types of biohazardous material. They are similar to conventional fume hoods in providing protection for the operator, but they also offer protection for the work in progress and for the environment. In most types of these cabinets, the work area is continuously bathed with positive pressure HEPA filtered air to protect product from contamination while an inward airflow protects the user. Some units re-filter a percentage of the air for re-use while venting the remainder to the outside, while others vent all air to the outside.

Bioreactor: A bioreactor is any device or system that supports a biologically active environment. Most commonly, it is a vessel in which is carried out a chemical process which involves organisms or biochemically active substances derived from such organisms. They are commonly cylindrical, ranging in size from liters to cubic meters, and are often made of stainless steel. Depending upon its normal mode of operation, bioreactors are classified as batch, fed-batch, or continuous.

Vessel Specialties, Pad-Depad Blanketing. The term PAD (tank blanketing) is the process of replacing the vapor of a storage tank with an inert gas. The term DEPAD (vapor recovery) is the process of relieving or venting the vapor space in the event of a pressure rise. A pad-depad valve is a self-contained, pilot-operated valve that maintains a blanket of inert gas on top of a stored product to protect it from atmospheric contamination. This reduces combustibility, decreases vaporization, controls vapor space pressure during in and out pumping operations, and helps to prevent the tank from entering a vacuum condition causing it to collapse.

Blending Mixers. These mixers consistently blend a wide variety of materials in powder, slurry, or liquid form. They can mix powder with powder, powder with a liquid, or several liquids together, and create a homogeneous product free of agglomerates or lumps. These mixers are available with direct heating jackets or cooling jackets.

Blower Vacuum Pumps: These are positive displacement pumps that operate by pulling air through a pair of meshing lobes not unlike a set of stretched gears. Air is trapped in pockets surrounding the lobes and carried from the intake side to the exhaust. The most commonly used type is called the Roots Blower Pump.

Boiler: A pressurized system in which water is vaporized to steam by heat transferred from a source of higher temperature. It consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam.

Bubble Tube

Bubble Tube Level Transmitters. These devices use a constant volumetric rate of gas flow, usually air, fed through a bubble tube submerged in a liquid. The pressure required to force the bubble gas out of the bottom of the bubble tube is equal to the hydrostatic pressure at that point. These transmitters have no moving parts, making them suitable for measuring the level of sewage, drainage water, sewage sludge, night soil, or water with large quantities of suspended solids. The only part of the sensor that contacts the liquid is a bubble tube which is chemically compatible with the material whose level is to be measured. The device generates an electrical signal that can be used to control a readout or other device. These sensors are designed to provide continuous monitoring.

Automated Butterfly Valve: The same as a manual butterfly valve (see above), except the valve mechanism is moved by an electric, pneumatic, or hydraulic motor which is controlled by a remote switch or remotely generated electronic signal.

  • SPEC #: 17960


Manual Butterfly Valve: A valve used to regulate fluid flow. It is similar in operation to a ball valve. A flat circular plate is positioned in the center of a pipe. The plate is attached to a rod that connects to an actuator outside the valve. The actuator turns the plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow causing a pressure drop.
