Stainless heat exchanger endures extremes

AlfaNova claims to be the world’s first 100% stainless steel fusion heat exchanger. It can handle pressures to 650 psi, temperatures up to 1020 F, and pressure fatigue cycling that would destroy conventional brazed units. The totally stainless steel construction offers corrosion resistance to media that would attack copper. This construction also provides greater mechanical strength and improved levels of hygiene.

UVC fan kit cleans air

Fan Coil UVC Kit provides mold and indoor air quality (IAQ) control, energy savings, and reduced maintenance. Each kit contains a UVC (ultraviolet C) emitter and power supply plus all necessary hardware to retrofit a fan coil. The kit makes it possible to install UVC lights in some of the most difficult to maintain yet widely used air conditioning systems and is designed for easy snap-in installation. Emitter tubes come in six lengths from 16 to 42 in.

Fan improves energy efficiency

Powerfoil fan provides cooling in summer and energy-saving destratification in winter. The fan increases energy efficiency by almost 400% and costs nearly 50% less to operate in the winter compared to other fans. In addition, cold weather heating costs are reduced more than 25%. Winglets can be added to increase airflow by 4 to 7% and energy efficiency by 16 to 22%. Fans are available in diameters of 6 to 24 ft — the latter moving up to 334,000 cfm.

Diffuser improves IAQ

Comfort 1stFiltered Diffuser addresses the two biggest complaints in an office, drafts from overhead diffusers and illness and allergic reactions from polluted ductwork. It combines four-way adjustable airflow along a horizontal plane. Four antimicrobial filters cover the discharge points inside each louver. The multidensity, two-ply filters remove pollutants as small as one micron and destroys most microorganisms.
