We have two 500 ton Absorber units in this facility, currently temperatures are cool outside (66 F*). We have been experiencing a 20 - 25 degree difference in Generator temperatures on the units. Our #2 unit consistantly is
20 - 25 degrees higher than the #1 unit. Average generator temperature on the #1 unit is 240 to 250 degrees, where as the #2 unit constantly runs 260 - 270 degrees. The #2 unit on startup runs right up to the edge before a generator pressure alarm happens, we run the unit on half fire then ease it back to full fire after the unit hits it's set point on chilled water. Any ideas?
