Danfoss has introduced the ICV (H)A4A control valve with flanges, the full replacement for all common flanged control valves on the market. Inspired by the ICV Flexline™ platform, the company said the ICV (H)A4A control valve’s modular design extends the lifetime of existing refrigeration installation while delivering a significant reduction in cost, energy, and servicing and maintenance times.
The UV Resources RLM Xtreme fixtureless UV-C lamp system delivers high-output ultraviolet energy to irradiate coils and destroy mold, bacteria, and microbes in high-volume HVAC environments. This modern UV-C system aims to help improve air quality, while creating a more energy-efficient HVAC system that does not need to waste energy to distribute properly conditioned air to the space.
NORD Gear Corp. has introduced the SK135E/SK175E soft start drive family, which the company says eliminates uncontrolled starting and mechanical strain on drive components. The starters are designed to be used in a distributed control system and can be mounted directly on the motor or near the motor
The Grundfos PACOpaQ® is a fully-integrated and compact HVAC packaged pumping system designed for chilled and hot water distribution, condenser water, geothermal loop, district heating and cooling, and many other water-based systems. The system pairs centrifugal pumps with the intelligence and efficiency of a dedicated HVAC control, which automatically determines the most efficient speed and optimum number of pumps needed to meet desired flow and pressure.
KMC Controls has announced the upcoming release of its new KMC Conquest™ BACnet® Router. The router is a key component of KMC's new Conquest line of BACnet direct digital controllers and appliances designed to connect building automation systems to the Internet of Things (IoT). The new suite of products provide system integrators and building owners with open, scalable, secure building automation solutions from a single building to enterprise-level installations.
The Atlas Operating Room Ceiling System (AORCS) from Titus HVAC has been designed for flexibility in critical environments like operating and imaging rooms. The new AORCS offers the ability customize piece by piece.
FS-Elliott Co. recently launched their Polaris+ series. Building on the design of FS-Elliott’s original industrial compressors, the Polaris+ line incorporates several new product advancements aimed to increase reliability and efficiency while maintaining low cost of ownership. The new Polaris+ series consists of five models with flows ranging from 900 to 11,500 icfm, 250 to 3000 hp, and pressures up to 150 psig.
The new Greenheck model EVH-501 is a wind-driven rain louver designed to protect air intake and exhaust openings in building exterior walls from direct water penetration even in the most extreme weather conditions.
Armstrong Fluid Technology has launched a new control product developed to improve the energy efficiency of chiller plants. Interfacing with an existing building or chiller plant automation system, the Armstrong OPTI-VISOR™ controls the key components of a chiller plant, providing the optimal operating settings for equipment such as water-cooled variable speed chillers, variable flow cooling towers, and variable speed pumps on the chilled water and tower water circuits.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
