LIRR Wyandanch Station

Uponor Snow Melt, Riello Array Boilers, Taco Pumps & Wessels


For this new construction project the engineers intent was to reduce the liability and potential hazardous conditions of snow/ice build up on the platforms for travelers along the LIRR.


In this one example (of multiple stations installed along the line), Riello AR2000 boilers were implemented to provide unmatched boiler plant redundancy and simplicity of equipment service. This helps ensure that any potential system down time as a result of routine maintenance, etc. is kept to an absolute minimum without drastically affecting the performance of the critical path snow melt areas for the general public. As each of these snow melt platforms are raised and exposed below, there is a higher potential for ice and snow accumulation to occur which can quickly become hazardous to the general public. In addition to the modular concept boilers implemented, Taco SKV vertical inline self-sensing pumps were implemented which are programmed to maintain the specific designed system flow rate. The internal logic of the pump VFD’s allow them to automatically compensate for any system fouling over time to maintain proper flow rate while also providing a lead lag function without the need for additional controllers or PLC’s. A Taco iWorx controls platform was implemented for automatic snow melt system operation and control using precipitation and slab sensors with the potential for off-site access by LIRR facility personnel.
