              Paragon Software Systems

              Carbon Minimizer

              Paragon’s Carbon Minimizer software is designed to reduce truck emissions and gas costs. The software monitors a truck’s fuel use and carbon emissions, then estimates and reports the total carbon dioxide and fuel content of the routes and schedules by measuring distance, speed, weight and fuel efficiency. The product configures its monitoring for slower urban journeys that use more fuel and carbon dioxide per mile than highway journeys.



                SafeRack’s G4 Series single-hatch truck-loading gangway is a self-contained system constructed with metal-stamping technology and a tool-and-die process. The product features spring-loaded gangway and platform operation, slip-resistant tread on the stairs, powder-coated handrails and mid-rails, heavy-duty bumpers and a four-rail design for fall protection.

                  Thermo Fisher Scientific Inc.

                  Emission Spectrometer

                  Thermo Fisher’s iCAP 6200 spectrometer is a dual-view ICP instrument designed for environmental and WEEE/RoHS analytical testing environments. The product features a purge gas distribution system, an RF generator, a charge injection device, and an enhanced matrix tolerance torch design that reduces plasma gas consumption.

                    Badger Meter

                    Flow Sensors

                    Badger Meter’s Series 380 and 735 Flow Sensors are designed to provide an all-in-one energy measurement solution. The Series 380 is made for HVAC contractors and energy engineer specifiers. The 380 comes with a pulse output, tee, two temperature probes, Btu calculator and RS-485. The 735 features a plastic tee-type, non-magnetic impeller flow sensor, and is made for small pipe size applications. The 735 has an internal preamplifier that allows a pulse signal to travel up to 2,000 feet without further amplification.

                      Thrush Co. Inc.

                      Air and Dirt Separator

                      Thrush’s Aar-O-Vent air and dirt separator is designed for corrosion protection in hydronic piping systems. The device uses a stainless-steel coalescing filter medium to separate air and dirt from water in systems that can cause damage to pumps, seals and valves. Features include a gauge tap on the inlet and outlet connections, a removable bottom cover for cleaning the coalescing medium, and a blow down valve for flushing collected sediment. Available sizes for the separator range from 1.5- to 24-inches.

                        Control Microsystems

                        Pump Station Controller

                        The FlowStation 110 from Control Microsystems is an out-of-the-box pump station controller package designed for use in storm and wastewater lift stations and common pump-up applications. The components consist of a pump controller, a color touch screen local operator interface, GPRS modem, SMS and e-mail alarming. An integrated BlackBerry interface is designed for central viewing and alarm acknowledgement. For larger water control systems, the package provides interface tools that exploit the product’s integrated Web server and Ethernet capabilities.

                          Red Valve Co.

                          Slurry Knife Gate Valve

                          Red Valve’s Series DX slurry knife gate valve is designed for heavy slurry applications. When the valve opens, reinforced elastomer sleeves seal against each other and provide a complete full-port opening, which minimizes turbulence and wear. When the valve is closed, the sleeves provide a drop tight seal. Each time the valve strokes, it is designed to discharge a small amount of slurry, keeping the gate path and seat area clear of entrapped particulates.
