What You Will Learn

David Lee will share his expertise in the design of parallel pumping systems for HVAC to reduce energy consumption and installation costs. He will also investigate why Armstrong’s Parallel Sensorless Pumps could be beneficial for your HVAC system and improve efficiency. The webinar will also compare Armstrong Tango pumps and DualARM solutions.
This presentation will be of interest to facility managers, operations managers, and HVAC design engineers.

Key topics include:

Background on HVAC systems
Why use parallel pumping systems?
Design considerations
The Tango and DualARM Solution
How to specify

Key questions answered during the webinar:

Do you have to enable each pump for a parallel pump operation?
If losing one of two pumps causes the other pump to ramp up, can we not factor that into our sizing for two pumps?
Where are some of the backgrounds on the heat transfer capacity when the flow is at less than 100%?
If you have two motors sharing one casing, doesn’t that cause a pressure loss in the piping immediately down the system and isn’t it better to use two separate pumps with separate piping?
For 50% capacity, you get 70% redundancy – is that standard selection on ADEPT?
Will pump vibration cause a problem for the VFDs?
If you don’t use remote pressure sensors, do you lose accuracy in measuring flow?
Do you have integral chiller or boiler packages with an intelligent pumping system?
Can you compare variable speed pumps with tango pumps?
