Mechanical Joints Resist Corrosion
The re-designed Fuseal mechanical joint allows for easier assembly, eliminates leaks and increases temperature range. The new joint features an EPDM O-Ring seal that accommodates system expansion and/or contraction as well as intermittent temperatures up to 210°F. It resists the corrosive action of alkalis, alcohols, acids, solvents and salt solutions. The joint will not rust, pit, scale, corrode or be affected by electrolysis. It provides for up to 1 in. of expansion or contraction during temperature cycling without losing the seal, allowing it to be placed in continuous temperature services as high as 180°F. The 3 in. and 4 in. fittings also have been streamlined for shorter lay lengths allowing the fittings to be installed in tighter spaces.

Metal-Seated Valve Employs Removable Cartridge
The Cartridge Valve is claimed to have a revolutionary mechanical-seal design for critical service applications. The valve uses aspects of ball valves, gate valves, and even triple-offset butterfly valves to protect the sealing surface during valve operation. A tapered hemispherical closure member (the hemi) rotates around a fixed core and wedges into a fixed seat to affect a mechanical seal. The closure member is rotated a quarter-turn by a valve stem that may be operated manually with a wrench or gear operator or automatically with a pneumatic, hydraulic, or electric actuator. It features a constant fixed core within the body to provide protection of the seating surfaces when the valve is opened, as well as minimizing turbulence as the valve is either opened or closed. The cartridge design affixes all the valve’s internal parts (core, hemi, seat, stem, bushings) to the bonnet and may be removed by unbolting the bonnet fasteners and lifting the cartridge from the valve body.

Thermal Treatment Tuns Biosolids into Gas
The Pyrobustor is a two-stage process, utilizing pyrolysis in a proprietary rotary drum followed by a post combustion system. Biosolids, sludge and other organic waste is pyrolytically transformed into an energy-rich gas. The residual non-volatile ash encapsulates minerals and metals, if present, into a stable inert form that permits disposal in landfills as a non-hazardous material. Depending on local market needs, the ash can also be used as filler for road construction, concrete products or similar applications. The unit is designed to treat biosolids streams up to one dry ton per hour. The space and energy efficient system works in conjunction with a dryer system to provide a 10:1 volume or mass reduction of dewatered biosolids. Waste heat from the system can be recovered for use by the dryer system or utilized to generate steam or “renewable” electrical power. Carbon credits may be generated from the reduction in emissions from transportation of the biosolids, and from generation of electrical power.
Thermocouple Data Logger Plugs Into USB Port
The OM-EL-USB-TC data logger measures and stores more than 32,000 temperature readings from either type J, type K or type T thermocouples which plug into a miniature female thermocouple receptacle at the base of the unit. The user can easily set up the initial data logging parameters including thermocouple type, logging rate, start time, high/low alarm settings, logging mode and desired temperature units (Celsius or Fahrenheit) and also download the stored data by plugging the module straight into a PC’s USB port and running the easy-to-use Windows software. Downloaded data can then be graphed, printed and exported to other applications such as Excel. The data logger is supplied complete with a long-life lithium battery. Data logger status is indicated by flashing red, green, and orange LEDs. This product suits the chemical, water, and pharmaceutical industries.
