Uninterruptible power supply

A three-phase, general-purpose uninterruptible power supply (UPS), the MGE Galaxy 3500 is suitable for 10- to 30-kva applications, such as small data centers and industrial environments. Relying on hot-swappable batteries, the UPS results in reduced downtime and increased runtime scalability. Its double-conversion online topology, critical for process-control, industrial, electrical-room, and automation-control applications, delivers zero transfer time and perfect regulation.

Spring-return actuators

AFB, AFX, NFB, and NFX spring-return actuators feature smaller housing for tight spaces and easier handling. AFB and AFX actuators have a minimum torque of 180 in.-lb, while NFB and NFX actuators have a minimum torque of 90 in.-lb. A universal power supply (in on/off models only) can accept from 24 to 240 vac. Manual override is standard on all models.

Heat pumps

Incorporated into a traditional heating loop, Invictus gas-absorption heat pumps are piped into hydronic heating systems along condensing or non-condensing hydronic boilers. The units have both heating and cooling capabilities. Fulton designs optimized heating systems by combining Invictus units with hydronic-boiler products and an intelligent control system. The heating systems have heating seasonal thermal efficiencies of approximately 146 percent. — The Fulton Cos.

Differential-pressure gauges

Available with bidirectional ranges, DM-1000 Digimag differential-pressure gauges have a full-scale accuracy of 1 percent on ranges of 2 in. wc and 2 percent on ranges of 1 to 0.25 in. wc. A menu key can be used to enter four simplified menus that provide access to security levels, digital damping for smoothing erratic process applications, updates to conserve battery life, and zero and span for field calibration.

Boiler-room controls

Firemaster programmable-logic-controller-based boiler-room controls feature color touchscreens with human-machine interface and are preconfigured for each boiler-room application. Communications are possible via Ethernet. Advantages include the ability to monitor remotely key boiler-room operations, such as boiler-water level, limits, alarms, or faults; pump operation; e-mail or paging of boiler-room alarms; day/night setback control; efficiency monitoring and calculation; and building-management-system interface.

Dry coolers

Dry coolers are designed for use in the industrial refrigeration, HVAC, gas-compression, petrochemical, and power-generation markets. The units provide cooling of water, ethylene-glycol/water, and propylene-glycol/water mixtures in a variety of closed-loop applications. Closed-loop cooling eliminates the cost of makeup water and water treatment associated with the use of cooling towers.

Hybrid fans

A hybrid fan composed of an aluminum supporting structure and a cladding/sleeve made of fiberglass-reinforced plastic, the HyBlade can be adapted to specific operational requirements for heating, ventilation, refrigeration, and climate control. The fan's optimized aerodynamic shape results in noise reduction and a significant increase in efficiency.
