15 models in the catalogue, flow 17 - 400 m³/min, pressure 6 - 10 bar.
How it works ↓
What is a water-cooled high-temperature dryer?
A refrigerated dryer that accepts inlet air up to 80 °C and rejects its heat into a water circuit: for large flows, where the air of an overheated room could no longer cool the condenser.

High-temperature refrigerated dryer, water-cooled, from 17 to 400 m³/min: large flows, on a site with a cooling water circuit and hot inlet air. Water carries the heat away where the air of an overheated room no longer could.
Without a water circuit, the air-cooled version covers the same flows up to 65 m³/min.
The combination of both constraints: air that enters hot, up to 80 °C, and water cooling.
It is the configuration of large air stations whose air comes straight from the compressor, without a sufficient aftercooler, in a room that cannot absorb the dryer's heat. Neither of the two simpler versions can handle this situation: the air-cooled high-temperature version would heat the room, and the standard water-cooled version would not withstand the incoming air.
The dew point remains that of a refrigerated dryer, +2 to +10 °C: these machines deal with an installation constraint, not an air quality requirement. To go lower, it is adsorption.
Fifteen models from 17 to 400 m³/min, inlet up to 80 °C, water-cooled. Industrial sites with a water network, a hot compressor room and uncooled air upstream.
80 °C inlet and water
Both constraints handled by the same machine, without adding an intermediate cooler to the network.
From 17 to 400 m³/min
The range of air stations, up to 400 m³/min, with the same family of connections as the standard water-cooled version.
Room protected
The heat of the incoming air and that of the refrigeration unit both go into the water circuit.
It is not an air class
The dew point remains +2 to +10 °C. A lower requirement is dealt with by adsorption, not by this machine.

Refrigerant dryer vs adsorption dryer: when should you switch to adsorption?
A refrigerant dryer covers most industrial applications with a +3 °C pressure dew point. Adsorption goes down to −40 or −70 °C but consumes compressed air. When should you switch?

ISO 8573-1 grades compressed air quality against three criteria, particles, water and oil, each on its own scale starting at Class 0. Which class suits which application? Full table and examples.
