DriSteem has developed a new wetted media system with five patent-pending technologies. The DriSteem Wetted Media System provides evaporative cooling and humidification for a wide variety of applications while taking advantage of the free cooling and energy savings.
The YORK brand of Johnson Controls has launched the YORK YK-EP “Efficiency Plus” water-cooled centrifugal chiller. The chiller achieves 5% capacity and efficiency improvements over the previous model. It utilizes a patent-pending mechanical compression economizer cycle to boost performance over conventional chiller platforms.
Rittal Corporation has introduced a new refrigerant-based rack and row cooling solution, known as LCP DX, for heat removal of critical IT components. The DX line is available in two models, as a Rack or In-line solution, and is ideal for small- to medium-sized data centers or computer rooms that need an efficient and cost-effective way to remove heat from IT equipment without the use of water or glycol.
Reliable Controls has launched a new internet data service (IDS) for RC-Toolkit which the company says enables users to configure MACH-Pro(Web)™ controllers to poll weather services over the internet and map retrieved values to BACnet objects. These objects can then be trended, employed in operational sequences, and displayed in graphics and energy dashboards.
Schaffner EMC introduced the ECOsine® Active 200/250/300A, a harmonic filter providing harmonic compensation in real-time for industrial and commercial environments. With a capacity of 300A, operating at 480VAC (+/- 10%), the connection-ready 200/250/300A (three-wire) cabinet models include forced air cooling and internal liquid cooling for the power electronics. The company said filters are capable of supporting large production facilities.
Pentair has now increased the protection level of its Hoffman PROAIR air conditioners NEMA 4 and NEMA 4X to IP66, especially for use in harsh and corrosive environments. In the food and beverage industry, as well as in highly corrosive environments, equipment is exposed to higher requirements. In cooling such facilities, the company says its Hoffman PROAIR air conditioners offer ideal protection.
Uponor North America is extending its current pre-insulated crosslinked polyethylene (PEX) pipe offering to include insulation thicknesses up to 2 in to comply with the ASHRAE 90.1-2013 Energy Code and the 2012 International Energy Conservation Code (IECC). The new offering includes both Uponor AquaPEX® pipe for potable plumbing applications as well as Wirsbo hePEX™ oxygen-barrier pipe for hydronic heating and cooling applications.
Greenheck has expanded its packaged rooftop ventilation line with the addition of Model RV(E)-120, a pre-engineered system featuring increased performance capabilities for larger dedicated outdoor air systems, multi-zone VAV systems, and single-zone VAV systems.
Continental Fan has introduced the new DXG & DXP AC Motorized Axials. The coupling of the motor and impeller minimizes space requirements and provides for vibration free operation. Both motor and impeller are located directly in the air stream, providing excellent heat dissipation and efficient motor cooling, according to the company.
