 | Energy Miser™ works with evaporator controllers to raise suction pressure, saving energy when loads
are light. |
| Automatically sequences compressors to their most efficient combination to
save energy. |
| Settings allow the compressors to always operate near the top of their
capacity to save energy. |
| Controls up to 15 compressors with common suction pressure. |
| Controls screw, recip, or rotary compressors in any combination. |
| Controls up to 2 different suction control set points per controller at different times of the day. |
| Starts, stops, loads, and unloads compressors provided compressor safety circuits are
OK. |
| Suction pressure set point controls within 1PSIG of the set point. |
| Unloads compressors as high discharge safety pressure is approached. |
| Shuts down on high discharge pressure. |
| Alarms on safety control set point violations. |
| Alarms on high suction trap liquid levels and shuts down compressors. |
| Monitors ammonia sniffer, shuts down compressors if leak in engine room. |
| Adjusts for non-linear slide valve capacity. |
| Logs compressor run time hours and alerts for planned maintenance. |
| Simple change of compressor control parameters (set points, deadbands,
time delays, etc.). |
| Works as Booster or High Stage, coordinates both stages when used in two-stage control. |
| The 1S10 controls 10 compressors in one stage; the 2S10 controls 10
compressors two stages; The 1S15 controls 15 compressors in one stage; the
2S15 controls 15 compressors two stages; the Omni controls 5 compressors in
two stages. |
| Monitors system kWh usage. |
| Allows special suction set points when special processes occur, such as
blast freezing. |
