Refrigerated Dryers

The RPC Series with Standard Energy Saving System

The ESS (Energy Saving System) is capable of transferring heat energy
through a change of state. During the thermal change process, the media’s
temperature remains constant—known as latent heat transfer. Latent heat
transfer occurs when the media changes from a solid to liquid or a liquid
to solid. The state of the media is monitored by a temperature probe that
automatically engages the refrigeration compressor to power on or off
according to varying inlet load profiles. Because the ESS is capable of
storing and releasing heat energy without a change in temperature, the
refrigerant compressor cycles less frequently and saves energy.

The dryer requires fewer components than conventional cycling designs
and does not require a cooling media circulation pump, storage tank and
glycol to refrigerant heat exchanger. All cooling is accomplished in the 3-in-1
heat exchanger.

The media within the ESS is non-toxic, does not require replacement and
maintains its thermal properties regardless of age. In the frozen state the
media will not thermally expand, maintaining the long-term integrity of the
heat exchanger assembly.

RPC Energy Saving Series 75–2000 scfm

The RPC Series is the ideal solution to reliably and
economically dry compressed air. The innovative
technology does not require a recirculating pump and
associated piping. This results in a simpler, more energy
efficient design.
