Invitation to Bid (ITB) for the supply of medical liquid oxygen and maintenance of the VIE system at Limbe Teaching Hospital, Douala, Cameroon

The Clinton Health Access Initiative with funding from Unitaid is preparing to implement a liquid oxygen (LOX) supply chain model in order to explore the effectiveness of an alternative supply chain in Douala to supplement existing oxygen sources. This supply chain comprises sourcing LOX from a cost-effective source, trucking/shipping it to Limbe Teaching Hospital, transfilling it into a bulk liquid storage tank, and then using the LOX in a newly procured VIE system (bulk liquid storage tank, vaporizer and pressure regulation devices).

CHAI invites interested and capable vendors to submit bids for the supply of one or more of the following products required for the supply scheme proposed above: medical LOX delivered to a selected facility, and maintenance of the VIE system as detailed in specification package (Annex B) of this ITB. When preparing your submission, please use the form attached as Annex A, and CHAI code of conduct and ethics for suppliers in Annex C for guidance.

All request for clarifications should be sent to  by the June 8, 2023 quoting ITB/CHAI/LOxM/CA/0223 in the subject line. Quotations must be submitted on or before 12 midnight WAT on June 15, 2023 via the email quoting ITB/CHAI/LOxM/CA/0223 in the subject line.
