GF Piping Systems has introduced the Type 514-519 High Flow Diaphragm Valve Series. The valves are designed to provide a true break-through for weir style valves. The valve features an optimized, turbulence-free flow geometry that offers significantly increased flow rate performance and lower energy consumption, according to the company. These features expand the valve’s suitability for applications where diaphragm valves were previously not considered due to flow restriction.
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.
Daikin Applied has expanded its Rebel™ commercial packaged rooftop systems from 3 to 15 tons to include 16- to 28-ton sizes, enabling owners of larger buildings to decrease the number of units required, reducing overall installation costs.
The Filterscan® WiFi Air Filter Monitor and Notification System from CleanAlert issues text/e-mail alerts when an air filter needs servicing –—ideal for operations or property managers responsible for servicing large or multiple facilities.
Spirax Sarco has released the CSM-C 600 compact clean steam generator. This unit is a skid mounted system that is designed to provide dry saturated steam that meets the requirements of HTM2031, HTM2010, and EN285 standards. The CMS-C 600 generator can produce up to a maximum of 1,275 lb/h of clean steam at 45psig — dependent on plant steam pressure and feedwater temperature. The generator can be used across a wide range of industries and in any application that relies on sterilization or humidification as part of its process.
AirMotion Sciences, Inc. has introduced its new line of 16-ft through 24-ft HVLS Fans known as their Big Simple Fans™. The company says both lines of AirMotion’s HVLS fans have small, highly energy efficient motors, and are used for cooling, heat de-stratification, ventilation, and as alternatives to air conditioning in large facilities. These industrial ceiling fans aim to offer improved performance over traditional HVLS fans, but with much greater versatility to reduce energy costs and environmental stress while enhancing comfort and productivity.
The new Valbia® VB008 Mini quarter-turn direct-mount electric actuator measures 4.75-in long by 2.75-in wide. Used with .25- to 1.25-in full-port direct mount ball valves, the company says it provides the compact and reliable automatic flow control for a wide range of HVAC, light industrial, and OEM applications.
The model 14359 UL/C-UL Listed Class 2 Transformer from Foster Transformer accepts line voltages of 120, 208, 240, and 480 V, 50/60 Hz, allowing near universal application. Its 24V, 75 VA rating provides ample capacity for most low voltage control applications, and its integral wiring compartment simplifies field installations, according to the company.
The WSG30™ system from Sensaphone® provides 24/7 remote monitoring of HVAC units, refrigerators, and freezers. It is ideal for locations where hard-wiring sensors are difficult or cost prohibitive. The WSG30 system is a web-based monitoring system that uses wireless sensors to detect problems such as temperature changes (from -109°F to 115°F), humidity fluctuations, water leaks, and power outages. A single WSG30 unit can support up to 30 wireless sensors.
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.
