A contract manufacturer (CMO) of active pharmaceutical ingredients (APIs) and intermediates required a low-temp chiller system to support their process expansions. One of their new manufacturing processes required Syltherm to be kept at -15 ºC and then further chilled to -19 ºC for the molecular stabilization phase in the reactor. Their existing chiller had been left idle and was unrepairable, so they needed a solution to get production up and running as soon as possible. As this process was only required for specific contracts, they wanted to avoid a large capital outlay and use a temporary solution that would allow them to take immediate advantage of the economic conditions.
