Introduction:

The Model 75 is an intermediate capacity water chiller offered by SPI Supplies. It is perfect for larger size diffusion pumps on laboratory size vacuum evaporators and some scanning electron and some transmission electron microscopes. It is also the optimum size for many older GC/Mass Spec systems.

Applications:

In addition to vacuum evaporator applications, a number of SEMs and TEMs would operate with this size chiller. Some representative examples:

Hitachi® S-520 and certain other models

Cambridge® S-150, S-188, S-250 and other models

Philips SEM 500, 501, 505 plus others
