Please do not combine different enquires in the same UNIVEX subject – use a fresh email if this is a new enquiry even though this is from the same customer. Finally, you change it last Friday.
Answering to your questions:
1. I am unable to recommend the scroll pump because I need the chamber size and required pump down time. The best recommendation is to check what is the specs (pumping speed) of the current scroll pump.
2. I will check with factory on the cool head. Just to confirm that the customer has a compressor which is needed for this cool head.
