The LAUDA-Noah POU has one moving part: a magnetically-coupled pump. This seal-less pump minimizes the risk of leaks, and is designed for continuous operation for the service life of the POU module, which is more than 4 years.
POU also incorporates solid-state Peltier devices, which provide both heating and cooling capacity to the system. These devices have no moving parts and temperature control is achieved electrically without the use of greenhouse gases. Consequently, LAUDA-Noah POU products are highly reliable, environmentally desirable, costing the end-user less to own and operate.
Compressor-based systems have large internal volumes, frequent leaks and oversized unreliable pumps, all of which require substantial routine maintenance.
