        Fluid Metering Inc.

        Dispensing and Metering

        Fluid Metering’s Smooth-flo PDS100 System is a valve-less dispensing and metering system that uses dual pumps to eliminate pulsation. Pump heads are mounted to the control unit, which includes stepper motors, drivers and programmable electronics housed in an anodized aluminum enclosure. The product is menu-driven and uses front-panel membrane switches and a large LCD display for programming. The system features pulse-free fluid delivery down to 15 uL per minute continuous flow.


          Drum Skimmer

          Elastec drum skimmers are designed to handle multiple types of petroleum spills, from jet fuel to crude oil. The skimmers recover oil by rotating a drum through the oil-water interface. Oil sticks to the drum surface and is recovered inside the floating head. These drum skimmers respond to vegetable oil and bio-fuel spills as well, and are effective in recovering pollutants in marine environments and industrial pits.

            EXAIR Co.

            Air Knife

            EXAIR’s Type 316 Stainless Steel Super Air Knife is designed for blocking harmful vapors and fumes on plating operations, blowing corrosive chemicals off parts, drying pharmaceutical products, and cooling hot materials such as molten glass, castings and molded parts. The uniform sheet of high-velocity air pulls in surrounding room air and amplifies it at a ratio of 40:1. The product can withstand temperatures up to 800 degrees Fahrenheit and contains no moving parts.

              Pressure Pipe Inspection Company

              Pipeline Condition Assessment

              PPIC’s PipeDiver™ is a pipeline condition assessment tool that provides information about the condition of pre-stressed concrete cylinder pipelines. The free-swimming tool collects data about the integrity of the pipeline. Dewatering is not required, so pipelines can remain in service during inspection. The system uses remote field transformer coupling technology, and detects pre-stressed wire breaks that could lead to pipe ruptures.

                Casella USA

                Portable Monitoring Station

                The Nomad portable data-logging weather station by Casella USA monitors wind speed and direction, barometric pressure, temperature, humidity, dew point and rainfall. A built-in solar panel supplies power and allows the device to run continuously in remote environments. The system’s data-logger has 512 K of internal memory and on-board data display. Users can communicate with the station via laptop, telephone or radio modem. The aluminum-based Nomad system weighs less than 30 lbs. and is supplied in three customized carrying bags.

                  United Electric Controls

                  Electronic Pressure and Temperature Switches

                  One Series explosion-proof electronic pressure and temperature switches by United Electric Controls are designed for plant safety alarm and shutdown applications that require a switch. The switches provide programmable adjustments, 0.1-percent repeatability, and do not require calibration. The units can be integrated into a safety instrumented system and are suitable for SIL1 applications. The series offers on-board diagnostics for each unit.

                    Farr Air Pollution Control

                    Dust Collector

                    Farr’s Gold Series GS4M Mini dust collector controls emissions from small airflow applications up to 2,000 cfm. The collector is a pre-wired unit with a low-noise fan (less than 70 dB), controls, motor starter, filters and cleaning system. It contains four HemiPleat® flame-retardant filter cartridges with 788 square feet of media. The automatic, reverse-pulse cleaning system is activated by an on-demand control panel. A safety monitoring filter is included to allow recirculation of the filtered air downstream for energy savings.

                      Modular SFC

                      Recirculating Evaporator

                      Modular SFC’s Centrifan Recirculating Evaporator works without a vacuum pump. The standalone device uses gas flow created by a spinning rotor and heater to accelerate the evaporation of aqueous and organic solvents. The blow drying continuously sheers off the top layer of liquid, while the centrifugal force holds non-volatile compounds in place. The unit is designed to save energy and laboratory space, and eliminate oil cleanups, heat, noise and vacuum tubing.

                        Breeze Software
