AXHP Series Ultra-High Pressure Refrigerated Air Dryers

Stainless steel from inlet to outlet

A tube-in-tube exchanger rated for the pressure class

The AXHP Series is the refrigerated dryer for compressed air and gas at pressures no ordinary dryer can touch: four pressure ratings of 1,200, 3,625, 5,000 and 6,000 psig, each offered in eight flow sizes from 20 to 275 SCFM, a matrix of 32 models. The high-pressure stainless steel tube-in-tube exchanger and all-stainless air-side components carry the pressure; the refrigeration side is a standard air-cooled R134a circuit on 115 V, 230 V or 460 V depending on flow. Every model connects with 1/2 in NPT and has a general-arrangement drawing behind it. It serves breathing-air fill stations, high-pressure test benches, gas transfer and process systems that need a 38°F dew point at line pressure.

Eight flows in each pressure class. AXHP-60-3625 is the 60 SCFM dryer rated 3,625 psig; AXHP-275-6000 is the 275 SCFM dryer rated 6,000 psig; Power draw depends only on flow: 0.29 kW at 20 SCFM, 1.05 kW at 100, 2.53 kW at 275, whatever the pressure class; 115 V single phase through 100 SCFM, 230 V at 125 SCFM, 460 V three phase at 200 and 275 SCFM; General arrangement drawings are published for every model.

Which pressure class. A 4,500 psig breathing-air cascade with a 5,000 psig relief valve takes the 5,000 psig class; a 3,000 psig system takes the 3,625 class; Flow is the free-air delivery of the high-pressure compressor: a fill-station compressor rated 45 SCFM lands on the AXHP-60; Where the pressure is under 725 psig the APET and HHPR Series are the lower-cost answer.
