About this file
This is a Questions & Clarification document for RFQ AA-2026-07 regarding heater procurement for Lawrence Berkeley National Laboratory (LBNL). The document does not address specific products, services, pricing, or award information, but rather provides clarification on technical specification deviations requested by a vendor.
The vendor sought clarification on four technical specification items. For Item 1 (tolerance specification), the procuring activity clarified that the tolerance is based on available installation space but vendors may propose alternative achievable tolerances. For Item 4 (316L stainless steel requirement), Items 3, 4, and 8 are designed to ensure magnetic permeability does not exceed 1.04, and vendors may propose alternative materials meeting this requirement instead of 316L stainless steel. For Item 8 (22AWG stranded NPC lead wire), vendors may propose alternative gauge wiring provided it satisfies the minimum requirements for maximum current. Item 9 was dependent on clarification of Item 8. All other terms and conditions of the RFQ remain unchanged, with submissions due by May 29, 2026.

Questions & Clarification
RFQ AA-2026-07
Question: There are some items in the technical specifications section that we need to deviate or come to some agreement on.
Answer: Please provide the list of specifications you propose to deviate from. We will evaluate each item and provide our feedback.
Question: In particular items 1, 4, 8, and 9.
• Item 1 – where did this tolerance come from? We haven’t used this on any of the heaters supplied to LBNL in the past.
Answer: The specified tolerance is based on the available space to install the heaters. If meeting this tolerance is a concern, the vendor may propose an achievable tolerance.
• Item 4 – we use a 300 Series SS but we don’t specify that’s it’s 316L SS. Is 316L SS absolutely required for the design?
Answer: Requirements 3, 4 and 8 are aimed at ensuring the magnetic permeability of the heater assembly does not exceed 1.04. The vendor may propose alternative material that meets this requirement.
• Item 8 – Please confirm that 22AWG stranded NPC is absolutely required Answer: See response to item4. Additionally, an alternative gauge of the lead wire may be proposed so long as it satisfy the mininum needed for the max current.
• Item 9 – We need to make sure we’re on the same page with Item 8 before we can comment on Item 9.
Answer: See response to item8
All other terms and conditions of this RFQ remain the same.
Submissions are due by May 29, 2026
