Description

 

THIS NOTICE CONSTITUTES AMENDMENT NO. ONE (1) TO THE COMBINED SYNOPSIS/RFQ FOR HEAVY DUTY CHILLER HEATER. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued.

The purpose of this amendment is to answer additional questions regarding the requirement.

Question # 1:

What is the actual lowest temperature needed to reach for this application? Is it actually -70 Degrees C or another value such as -50 Degrees C?

Answer # 1:

The no-load temperature should be -70C or less and the unit should be capable of lifting 250W load at -70C. This includes all loads external to the chiller (parasitic loads as well as dissipation in the object being cooled).

Question # 2:

How has the Pump Capacity, 4.0GPM at 30 PSI and 2.0GPM at 60 PSI, been determined? This capacity is extremely high and not feasible with most products in this class.

Perhaps there are factors that we could account for that would allow us to revisit that specification requirement. We would be happy to assist with calculating those specifications.

Answer # 2:

This is a minimum capacity that is believed to be sufficient based on lab testing with the chiller being replaced.

Question # 3:

What is the delivery time-frame required by NASA for this unit?

Answer # 3:

1 month

The due date for receipt of offers is not extended.
