RFI QUESTIONS -Solicitation # 36C10D23R0004 Replace Dehumidification units
• Dehumidification units were designed specialty for the VBA, the company is no longer in business and no one makes anything close to the weight & size & power of the old units.
All new units, are longer, wider and heavier with a higher power requirements. Does VBA have any architectural, engineering drawings for load calculation on the existing roof to handle a larger unit?
We do not have any architectural drawings or engineered drawings for load calculation.
• The new RTU’s power requirement is more than the existing RTU, can the breakers be upgraded to meet the power required?
We could upgrade breakers, if necessary.
• Existing units are about 5000 pounds new units are about 10,000, this would require engineering and new roof penetrations for the larger units is the VA good with roof penetrations?
No new roof penetrations
• With existing cabinets being surprisingly very good shape, Will the VA be opposed to value engineering/refurbish the existing units with new parts?
1. Compressors
2. Coils
3. Controls
4. Relocate dx evaporator to be in first in the airstream. We will not get quite as low a dew point as the original design, but be a far more reliable system.
5. leave existing blower and replace blower motor.
We would not be opposed to refurbishing/using the old cabinets as long as everything is removed and replaced with NEW Motors, coils, compressors, UV lighting, controls, door handles, seals for doors and limit switches that control lighting etc.
