System Information
The Rack Mount Chiller (RMC-800, RMC-1100) is a turn key 2U (3.5 in. tall) chiller system. The RMC
provides a user interface to control the coolant setpoint, pump speed and alarm settings. The system
maintains coolant supply temperature with a PID loop that varies the compressor speed. Details on the
system interface and performance are included below.

Safety
The RMC contains
Tetrafluoroethane (R-134a)
as a refrigerant. R-134a is an approved long-term
replacement for CFC-based refrigerants and an approved ozone depleting substance (ODS) alternative.
In the event that the RMC is damaged, general work clothing, leather gloves, and eye protection should
be worn to prevent exposure to refrigerants. The RMC also contains Polyolester (POE) oil, which is used
by the compressor. Contact Aspen for the MSDS for either of these internal fluids.
Precautions relating to the personnel hazards regarding contact with this substance should be outlined
in training and technical manuals.
Disposal of R-134a must comply with federal, state, and local disposal or discharge laws.
WARNING! R-134A is subject to U.S. Environmental Protection Agency Clean Air Act
Regulations Section 608 in 40 CFR Part 82 regarding refrigerant recycling, therefore the
refrigerant must be evacuated from the RMC prior to disposal of the assembly.
CAUTION! Skin contact with refrigerant may cause frostbite.
