According to ClimateCraft, its new ACCESS™ knockdown air handling unit is a time- and cost-saving solution. ACCESS aims to provide a unique solution in custom-engineered and manufactured knockdown AHUs, addressing challenging retrofit projects by examining the typical challenges associated with air handling equipment replacement — including limited access to installation spaces (such as facilities originally built around mechanical equipment), zoning and code requirements, original equipment demolition, project timeline constraints, and budgetary limitations.
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.
Honeywell has introduced its Silent Knight® low frequency sounders and sounder bases, plus an amplifier to provide code-mandated backup power capabilities for emergency communication systems.
