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.

Filtration products

Used on cooling systems worldwide, Orival offers individual automatic filters, manifolded multifilters, and skid-mounted water-treatment systems to remove organic and inorganic suspended solids from cooling water, decreasing deposition on heat-transfer surfaces, reducing sites for microorganisms to colonize, and preventing the clogging of nozzles, orifices, and valve actuators.

Globe valves

Flowrite 599 Series two-way flanged iron-body globe valves are designed to work with pneumatic or electronic actuators with a ¾- or 1½-in. stroke. Features include a high-pressure, 200-psi close-off for all line sizes, giving these valves the ability to close against high differential pressures and meet specifications for more applications. A stainless-steel trim reinforces the durability of the metal-to-metal seats and plug.

Condensing boilers

The Triple-Flex series of high-efficiency condensing boilers includes four models that offer inputs from 1,500 to 3,000 mbh with less than 30 ppm of nitrogen oxide while utilizing a hybrid metal-fiber burner. The boilers deliver a minimum operating efficiency of 90 percent with 160°F return, 180°F supply, and a 100-percent firing load.

Low-pressure transducers

CXLdp low-pressure transducers now are available with jumper-selectable 0- to 5- or 0- to 10-vdc outputs, as well as the original 4-20 mA output configuration. Engineered to provide stable differential-pressure measurement in HVAC building-control systems, the transducers have 20 standard pressure ranges capable of withstanding 15 psi without damage or calibration change. A small housing and multiple installation options allow the transducers to be attached to a DIN rail, conduit, or wall.

Commercial fans

For commercial spaces with ceilings as low as 12 ft, Isis fans are 8 to 10 ft in diameter and feature a proprietary prime mover that allows the fans to operate silently and without electrical interference. The fans work in conjunction with HVAC systems to distribute conditioned air and reduce energy use. — Big Ass Fans

Alternating-current drives

The E7S slim-configured alternating-current drive package (1 to 40 hp at 208 v and 1 to 100 hp at 480 v) includes as a standard feature an input disconnect, with space for several commonly used options, such as reactors, input filters, and circuit breakers. The slim package meets the space requirements of end users, yet has the flexibility to meet the varying requirements of specifying engineers and HVAC designers.

Fabric ducts

For commercial retrofits and new construction, UnderFloorSox fabric air-dispersion ducts are designed to reduce thermal decay and improve temperature consistency within an underfloor-air-distribution (UFAD) plenum. Twelve to 18 in. in diameter, the ducts are routed through a UFAD plenum to distribute even air dispersion and temperature to perimeter, remote, and other high-heat-load zones that typically suffer thermal decays of 6°F or more.
