The problem of unwanted moisture in HVACR systems has been an industry evil for years. How to deal with it is resulting in a widening range of solutions. To the familiar approaches of using filter driers, nitrogen purges, and multiple evacuations, manufacturers are adding use of sealants as well as dehydrating and activating agents.
Now that you are basking in what hopefully has been several profitable months, I’m here to give a reality check. We don’t want to give away in the last three or four months of the year all that we worked so hard to earn.
Featuring high EER — up to 22.2 at full load and 29.8 in part load — SmartSource™ water-source heat pump products offer low noise operation and a wide range of features and options. The electrically commutated motor (ECM) is a standard feature across the entire product line.
Four fans connected in parallel provide built-in redundancy in the PowerAire® Quad fan assist module. Designed for data center installations, the module manages the cooling requirements for dense server racks and blades. It provides a blast of cooling through the DirectAire® airflow panel.
Redesigned and featuring 15:1 turndown for energy efficiency and low NOx emissions, the Benchmark 6000 (BMK6000) is a 6 million-Btuh condensing hydronic boiler. It has an operating efficiency of 92.5 percent. The unit measures 79 (h) by 34 (w) by 109 (d) inches.
If your company is experiencing personnel issues, productivity challenges, dysfunctional work teams or all of the above, it could be caused by the generational clash between two age groups that make up the largest segments of the workforce. How do you deal with it?
Each owner who has spent millions of dollars on a new or refurbished building has every right to expect that the mechanical systems will keep tenants comfortable, while delivering every Btu and saving every kilowatt-hour possible. Commissioning agents make sure it really does happen that way.
There is a unique community development program underway in Phoenix that is bringing together manufacturers, architects, engineers, general contractors, sub-contractors, and the community to erect LEED platinum designed school structures built entirely by volunteers.

A line of PVC and CPVC duct dampers offered in butterfly, gravity, and blast gate types for fume removal applications is available. The backdraft dampers come in three flow control types: butterfly for balancing airflow, a gravity backflow preventer which closes when the air pressure stops, and a blast gate for on-off.
