Indirect Refrigerated Air Dryer (SH)
SH Series Indirect Cooling Refrigerated Air Dryer
Removes moisture through indirect heat exchange between the compressed air and chilled water (or brine). A stainless steel shell-and-tube heat exchanger keeps dew point variation gentle, with manufacturing and delivery references above 30,000 Nm³/h. Built in-house by a KGS-registered refrigeration unit manufacturer.
Cooled indirectly by chilled water: the SH series
The SH series is an indirect dryer that removes moisture from compressed air through indirect heat exchange with chilled water (or brine).
It is advantageous at sites that already have chilled water infrastructure, and its gentle dew point variation gives stable operation.
We have manufacturing and delivery references above 30,000 Nm³/h.

KGS Registration — Refrigeration Unit and Specified Equipment Manufacturing under the High-Pressure Gas Safety Control Act
SH series indirect refrigerated air dryers are built at the GENEQ Gimhae plant, which holds manufacturing registrations for refrigeration units (packaged water-cooled and air-cooled) and refrigeration specified equipment (condensers, evaporators and pressure vessels) under Korea's High-Pressure Gas Safety Control Act (registered 17 February 2025). This is what the Korean market commonly calls "KGS certification": equipment subject to inspection by the Korea Gas Safety Corporation (KGS), designed and built by a registered manufacturer.
Because we build the refrigeration unit and the pressure vessels in-house rather than outsourcing them, KGS inspection, delivery and after-sales service and parts are handled by one company. The original certificates are on our Certifications page.
