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.

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.

Combustion analyzers

Useful for field technicians, ECOM EN2 portable combustion analyzers measure oxygen, carbon monoxide, carbon dioxide, nitric oxide, and nitrogen dioxide as well as temperature, stack draft/pressure, efficiency, and excess air. An internal pump and Peltier gas cooler with automatic condensate drain ensure accuracy and longer sensor life. Standard features include an on-board printer, secure digital memory card, and wireless Bluetooth.

Kitchen hoods

An auto-cleaning kitchen hood that handles grease extraction and filter cleaning, Grease Grabber H2O incorporates a dual-stage filtration system that combines Grease-X-Tractor and the Grease Grabber filter to remove 100 percent of grease that is 5 microns or larger from air streams. This works in conjunction with a solenoid-powered system in the hood that sends hot water mixed with detergent to spray nozzles aligned along the filter banks and plenum area. The mix is recaptured, and a high-efficiency pump recirculates it to conserve water. The system purges and rinses with fresh hot water, eliminating the need to remove and clean filters by hand. — Greenheck

Torque wrenches

Torqtite adjustable open-end torque wrenches allow all tube and hose ends to be tightened to their correct torque requirements. Developed to compliment Flaretite's flared seals for 30-, 37-, and 45-degree flared fittings, the wrenches have a low profile and reversible spanner design. The wrenches also are supplied with torque rating tables for common fittings.

Inline draft inducers

Able to be installed in a vertical or horizontal stack section, IPVB Power Venter inline draft inducers are available in four sizes with capacities of up to almost 6,000 cfm. Made with Type 316 stainless steel, the inducers are designed to provide proper draft for condensing and non-condensing commercial boilers and water heaters. They integrate easily with most chimney and stack systems using flanged or slip fittings.

Dehumidification systems

Liquid-desiccant dehumidification systems deliver precise, energy-efficient temperature and humidity control to a range of industrial, commercial, and institutional applications regardless of air-inlet conditions. The dehumidifiers also provide critical bacterial control by capturing most airborne bacteria, viruses, and mold. The equipment can use waste heat efficiently and support on-site power generation and cogeneration. Able to handle airflows from 750 to 84,000 cfm, the equipment is made of fiber-reinforced plastic.
