SUMMARY OF CHANGES

Solicitation/Contract Form Continuation

The following changes have been made:

Miscellaneous text in this section has been modified to:

Amendment #1 question

Question: What is the required CFM?

Required CFM @ 145 psi should range from 32-36 Answer:

Amendment #2 questions (clarifications)

Question:

1. What is the minimum CFM needed__ __32

2. What is the maximum CFM needed__ __36

3. What is the minimum working PSI needed __ __150

4 What is the maximum working PSI needed __ __175

Answer: The minimum working pressure is 145 psi that needs to always be present, so the pneumatic systems work properly. The absolute minimum needs to be 150 psi in the tank, so we don't start cutting critical systems short of pressure.

Question: Could you please confirm whether they're looking for a desiccant dryer post receiver tank?

At this size, horizontal air receivers aren't an option, so we can quote a vertical design. Also, note that for this horsepower rating, we use a direct drive instead of a belt-driven VSD.

Answer: Yes, we're looking for an external dryer. It doesn't need to mount to the tank, just piped into from the exit side of the screw compressor, orientation doesn't matter.

Question: What is the flow in CFM demanded by this application?

The demanded flow at 100 psi is right around 350 CFM.Answer:

Question: pressure is needed at the point of use? What minimum

The minimum needs to be 145 psi.Answer:

W912ES25QA0130003

Question: What ISO class of air quality is required?

No ISO air quality is required.Answer:

Question: Is there room for additional receiver volume?

Not much, I'd say 5-10 gallons at most.Answer:

Amendment # 3 Questions:

Question: spec stated a 30-40 HP unit which would be roughly 150-180 CFM; but in the The original updated answers you reference both an approximated 40 CFM need as well as300 CFM requirement.

1. What is the minimum CFM needed____ 32

2. What is the maximum CFM needed____ 36

The demanded flow at 100 psi is right around 350 CFM.

Answer: There needs to be a zero behind those two numbers.

1. What is the minimum CFM needed____ 320

2. What is the maximum CFM needed____ 360

Question: In the original quote they requested an integrated dryer on the unit or what we reference as a full feature unit. Are they requesting two dryers? Or just one external paired with a pack unit? If a second dryer is requested on top of the integrated unit dryer, do they need a desiccant dryer or refrig?

Answer: The compressor has an internal dryer, and the Goetz crew requested an additional dryer. The additional dryer will not be physically attached to the compressor but mounted somewhere close to the exit line. The external dryer shall be a Non-Cycling Refrigerated Air Dryer.

Question: dew point is required by the external dryer? What pressure

Answer: 39 degrees Fahrenheit
