1. Introduction
2. Important Safety Instructions
Tripp Lite’s SRCOOL33K/SRXCOOL33K is a self-contained air conditioning unit housed in a standard 42U enclosure. The SRCOOL33K/
SRXCOOL33K is optimized for general computer room cooling or supplemental cooling in a large server room. It features an inverter-driven
DC (direct current) variable-speed compressor that delivers high-efficiency precision cooling. This helps maintain set temperature without the
traditional method of wasteful On/Off cycling.
A menu-driven, multi-line LCD screen provides on-site monitoring and control of various operating conditions. These operational conditions
can also be monitored and controlled remotely via SNMP, Web, telnet or Modbus.
