![]() These CataStak systems are available with rental and new boilers, as well as for sale for retrofitting on user-owned boilers.įield installation is easy, the firm says. Portable selective catalytic reduction unit Click here to enlarge imageĪ newly designed portable selective catalytic reduction (SCR) system is immediately available for use with virtually any package watertube boiler in a range of 50,000-150,000 lb/hr.

The TML is capable of performing these operations offshore as well as inshore: lift from transport vessel onto substructure move an object to a higher or lower elevation lift off from substructure, transport, and reinstall in new location lift off from substructure, transport to storage area onshore lift from heavy-lift transport vessel or barge to suitable pier and lift off from pier onto barge or heavy-lift transport vessel. The basic idea of the concept is to create the lift by deballasting of the buoyancy tanks and at the same time ballasting the ballasting tanks. One barge with lifting arms is positioned and moored on each side of the platform. Each lifting arm is equipped with a buoyancy tank on the inside (between the barge and the platform) and a ballast tank on the outside. Each lifting arm is hinged to the skid structure at the center of the barge. The lift arms are supported by a saddle on a skid structure on board the barges. ![]() The size of each barge is 120 by 43 by 8 m. It consists of 2 customized barges, 6-12 lift arm systems, and 1 heavy transport vessel or barge for transport to port or a new site. The twin marine lifter (TML) system is based on buoyancy and ballast tanks and lifting arms located on barges. Offshore heavy-lift systemĪ new offshore heavy-lift system promises to provide safe, cost effective, and environmentally friendly solutions Source: ControlAir Inc., 8 Columbia Drive, Amherst, NH 03031. The unit is suited for valve actuation applications on gas transmission and distribution pipe lines, SCADA operated systems, and DCS operations. Flow capacity is 5 scfm, and relief capacity is 1.4 scfm. Its temperature range is -40° to +150° F. The converter is available with a 12 v dc or 24 v dc motor and four motor speeds. the stainless in-line filter protects against potential contamination in the supply line. The stainless steel construction of the main regulating valve helps prevent corrosion and ensures long, uninterrupted operation. The explosionproof, NENMA7X enclosure and stainless steel regulator construction allow the unit to not only operate in remote, hazardous area applications but also withstand the forces of hostile environments. Another set of switches provides feedback, which informs the operator (remote or on-site) whether the valve being controlled is in an open or closed state. The converter comes with limit switches that help prevent motor burnout by automatically stopping the motor when the high or low set point is reached. If there is a power failure at the site, the regulated output pressure and valve position remain the same. The rest of the time the 1200 simply acts as a spring-operated regulator.Īnother feature is fail-safe operation. This unit has no power consumption except when the motor is being operated to change the pressure setting. diaphragm controlled pressure-regulating valve and converts the dc signal to a variable pneumatic output. It uses an electronically operated reversible 24 v dc motor, which accurately positions the stainless steel. The Type 1200 Eltop electric to pneumatic converter is a rugged, low power consumption pressure regulator designed for remote locations.
