Expanders are a common piece of electrical equipment that plays a vital role in frozen cryogenic use environments. However, due to the special nature of the cryogenic environment, the maintenance of expanders becomes particularly important.
In low temperature environments, the performance of the expander can be affected and therefore frozen components need to be replaced on a regular basis. Before replacing parts, it is necessary to ensure that the expander has been completely removed to avoid damaging other parts.

When using the retractor in a low temperature environment, attention also needs to be paid to the energy consumption. The load of the retractor needs to be checked regularly and the operation of the retractor needs to be adjusted according to the load.
