In an aspect, a system includes, but is not limited to, a storage tank configured to hold a cooling medium in a fluid state; first and second circulation pumps fluidically coupled to the storage tank; a single cooling medium header fluidically coupled with each of the circulation pumps; a first dryer module configured to direct a first portion of cooling medium from the single cooling medium header past a first stream of compressed air and to direct the first portion of cooling medium back to the storage tank; and a second dryer module fluidically configured to direct a second portion of cooling medium from the single cooling medium header past a second stream of compressed air.

A gas cooler effectively prevents or suppresses an outflow of drain water to the outside. The gas cooler includes a casing, a cooling unit, a seal plate, a lead-in port, a lead-out port, and a drain scattering prevention member. The cooling unit is accommodated within the casing and cools gas. The seal plate is provided in the cooling unit and partitions an inside of the casing into an upper space thorough which the gas before passing through the cooling unit flows and a bottom space through which the gas after passing through the cooling unit flows. The gas is led from the lead-in port into the upper space, and the gas is led out of the bottom space via the lead-out port. The drain scattering prevention member is disposed in the bottom space, and collects the drain water, while allowing the gas to pass therethrough.

A heat exchanger with a housing (3) that contains a set of channels (12); an inlet collector (4) having an inlet collector chamber (9) with an inlet (5), wherein the inlet collector chamber (9) includes first flow distribution means (10) configured to distribute a flow originating from the inlet (5) evenly over the set of channels (12); and an outlet collector (6). The first flow-rate distribution means (10) consist of a single body (15) that comprises two flow-conducting surfaces (16), which are symmetrical with respect to each other according to the first plane of symmetry and the second plane of symmetry, and which two flow-conducting surfaces (16), as seen from the inlet (5), are inclined downward in a first direction perpendicular to the first plane of symmetry and/or in a second direction perpendicular to the second plane of symmetry.

A counterflow heat exchanger includes a first fluid inlet, a first fluid outlet fluidly coupled to the first fluid inlet via a core section, a second fluid inlet, and a second fluid outlet fluidly coupled to the second fluid inlet via the core section. The core section includes a plurality of first fluid passages configured to convey the first fluid flow from the first fluid inlet toward the first fluid outlet, and a plurality of second fluid passages configured to convey the second fluid flow from the second fluid inlet toward the second fluid outlet such that the first fluid flow exchanges thermal energy with the second fluid flow at the core section. One or more drains are operably connected to the plurality of first fluid passages configured to remove condensation from an interior of the first fluid passages prior to the condensation reaching the first fluid outlet.

A heat exchanger having a fins and tubes heat exchanger coupled to a plates heat exchanger and an open sided bypass compartment facing one of the edges of the fin and tubes heat exchanger. The plates heat exchanger has an inlet zone and an outlet zone. The heat exchanger is configured to guide a fluid to flow from the inlet zone, through inlet pathways between plates of the plates heat exchanger, and fins of the fins and tubes heat exchanger then toward the bypass compartment, then in between the fins facing outlet pathways, toward in between the surfaces of the plates facing the outlet pathways, and then toward the outlet zone.

A dry air generation apparatus includes a first heat exchanger, a second heat exchanger, a switching valve, and a controller. The first heat exchanger and the second heat exchanger are provided in the air flow path, and the moisture contained in the air is removed by cooling the air which flows through the flow path to 0° C. or lower. The switching valve switches the direction of the air flowing through the first heat exchanger and the second heat exchanger. The controller controls the first heat exchanger, the second heat exchanger, and the switching valve. The first heat exchanger and the second heat exchanger are connected in series in the air flow path.

A scraped heat exchanger apparatus, including a vessel and a plurality of internally cooled plates disposed parallel to each other within the vessel. A rotating shaft is disposed at a central axis of the vessel. A rotating scraper arm, connected to the rotating shaft, moves between adjacent plates. The rotating scraper arm includes a scraper positioned to scrape solids from the outer surfaces of adjacent plates. A cooling fluid flows through an interior of each plate. The cooling fluid cools a gaseous process fluid flowing between adjacent plates. An opening in each of the plates permits the process fluid, and solids removed from the process fluid and scraped by the rotating scraper arm, to pass through the plates.
