Refrigeration hours 99,000+ Refrigerant: R23/R404A Power requirement: 480V/24A three phase Other facilities requirements: water for humidity system. Drain. There's no air purge on this chamber. Cooling: Water cooled; 1" NPT connections are provided. This chamber requires a fair amount of water at room temp in order to run at full capacity. Interior dimensions: 23.5" wide, 36.5" deep, 32" high Compressors: Two Copeland 5hp, bolted construction. Chamber heat: 4.5kW Steam generator: 4.5kW Humidity sensor: wet wick Controller: Thermotron 4800 it achieved -25C from 20C in five minutes; a further seven minutes resulted in -50C. Nine minutes were required to reach -60C from -50C. The heater works; it draws 6A at 480V three-phase. The steam generator shows good continuity. The humidity sensor does not work and the humidity coil did not energize when we enabled humidity in the control. The humidity water fill does work. A tag by the data plate states a refrigerant conversion was performed in 1995 from R13/R502 to R23/R404A. At this time a refrigerant expansion tank was added at the top of the chamber. Apparently, the 4800 control is original to this unit; it has several option cards including GPIB. The chart recorder is a Truline by Honeywell; it seems to work but we did not have a paper to test it with. A Destaco latch was installed to remedy a door leak. No manual or shelves are included.配置
