Features
Control Features:
- Compressor Protection Technology: Our compressor protection technology uses start-to-start anti-recycle control logic to limit cycling under low-load operating conditions to extend compressor life.
- Compressor and Pump Run Hour Displays: The ability to monitor compressor and pump running hours is an important tool to assist with scheduling maintenance.
- Power Monitor: The main power monitoring system protects the chiller from extensive damage to the compressor and pump due to loss of phase or phase reversal in the main supply.
- Reservoir Low Level Alarm: Indicates a low process fluid condition and protects the process pump and chiller from expensive damage caused by a critically low operating level in the reservoir.
- Temperature Warnings and Alarms: A warning alerts the operator of a potential problem before a fault occurs and if the condition gets worse, an alarm stops the chiller to prevent damage.
- Adjustable Alarm Time Delays: Allows for programing a start-up alarm time delay to deactivate the alarms long enough for the process loop to stabilize before activating the alarms.
- High-Quality 24 VDC Power Supply: The 24-volt DC power supply ensures dependable control circuit power and isolates the control circuit from static interference to ensure stable and precise operation.
- Trending Charts: All control systems include the ability to chart key operating parameters, such as process fluid supply and return temperatures, for a quick display of operating trends.
- Stepper motor driven hot gas bypass
