Modular Boiler Plants: How To Make Them Deliver

Modular Boiler Plants: How To Make Them Deliver

A boiler plant that is constructed off-site and shipped offers some unique advantages for the design and construction process — and sometimes for the longer life of the facility, too. As you might imagine, the strategy also involves some unique engineering obligations and responsibilities along the way. Learn the essential components for getting high quality performance from a modular project.

ECM Motors For Large Central AHU Designs

Historically used in smaller-load residential settings, electronically commutated mo-tor (ECM) technology is making the leap thanks to recent improvements and in-creased awareness among engineers. Start with the basics, proceed to advantages and caveats, and consider the ways ECM designs can streamline the economics of air movement.

Look at not only some nearly automatic benefits-in-waiting for your average hospital boiler retrofit, but also at some ideas for what to do if there isn’t budget for a full replacement. Meanwhile, a short laundry list of hospital-specific boiler considerations actually includes the laundry (but not how you might expect).

ASHRAE 170 is just the baseline for the fight against hospital acquired infections (HAIs). The ongoing human and financial tolls taken by these infections point to the need for engineers and facilities to raise their IAQ game wherever possible. Move beyond the minimum and get into the what, where, and how of HEPA filtration, ultraviolet technology, and catalytic air cleaners.

Chiller Retrofits In Health Care Facilities

One of the worst things you can do is note the capacity and replace the chiller. Have the building loads and usage changed? What about motors and cooling towers? Consider these and your part-load realities to create real long-term improvements.

Motor Selection HVAC Design

Who actually specified that motor? Did they keep the entire system in mind or were they simply specifying one component at a time? And will that spec require over-speeding the motor?

Calculated With Care: Ventilation in Health Care Systems

A Mississippi clinic needed above-average design on a budget. The equipment was nothing unusual. However, creativity and attention to detail uncovered opportunities to fine-tune the design and exceed ventilation benchmarks for less.
