-HT supercooler coldhead, optimized for service at 100K and up, for 102 & 132 models only

Option Description Details   

Custom Windings (-CW option)  
-enables non-standard voltage/current combinations or special insulation ratings on standard motor/alternator stator sizes
-replaces standard windings with different turns count and wire size or specification.  
-Order must specify, # turns, coil connections, wire size and insulation grade.  
-CW stators will be permanently marked (etched) with turns, size, & grade info of winding. 

Split Leads (-SL option)
-enables multi-tap operation of motor/alternators in various parallel/series combinations.  
-comprises disconnected coils with individual leads, or fractional sets of coils with separate pairs of leads.  
-Order must specify number of lead pairs and associated coil connections.

Buyer Custom (-XX option)
-special modifications specified by buyer with Qdrive agreement 
-examples include custom mounting features, additional services (e.g., special testing) or auxiliaries (e.g., storage dewar or custom skid base).

Seal Verification (-SV option, w/ verified seal fit):
This option provides verification of seal clearance by measured flow in assembly before shipment.  
Qdrive has validated these measures against full machine performance in many configurations.
