“Free cooling,” the process of allowing the building load to bypass mechanical cooling and exchange its heat with lower temperature outdoor air, is an environmentally favorable approach that helps reduce operating costs.
This technology harnesses the power of evaporation to lower ambient air temperatures entering Carrier’s 30XV chiller – helping to reduce chiller power consumption, increase reliability and extend the life of the chiller.
These National Sanitation Foundation (NSF)-certified valves offer lead-free brass bodies (ball valves), ductile iron ASTM A536 (butterfly valves) for on/off or floating point control with operating ranges up to 230 psi, depending on the series.
Enhancements stem from more than two years of additional input from engineers, contractors and building owners – resulting in a substantially upgraded, interactive Building Efficiency System Tool™ (BEST).
