LPT Pulse-tube coolers

For applications where life time and vibrations are key requirements, the LPT series is the preferred choice. These coolers combine a flexure bearing moving magnet compressor (as in the LSF series) with a pulse-tube cold finger. This results in a design that is intrinsically balanced and therefore low on vibration, while eliminating the need for a moving mass in the cold finger, thus improving reliability by removing a potential wear mechanism.

Three different LPT cooler types are currently available, with maximum cooling powers ranging from 1.4 W up to 15 W at 80 K tip temperature.
