8 MR Suite Temperature and Humidity
CAUTION
Equipment Failure
Failure to maintain the required temperature or humidity at all times (i.e., both
working and non-working hours) may result in equipment failure, scanning failure,
or warranty void.
Ensure the HVAC system has the correct capacity for the room size, equipment
heat output, and environmental conditions to maintain proper temperature and
humidity.
This section provides temperature and humidity requirements for the MR suite. Specific
construction requirements for each room can be found in the following sections:
•
Magnet Room
•
Equipment Room
•
Operator Room

2.
Operating humidity gradient limits shall be between -5% RH/hour and 5% RH/hour, when averaged over 1 hour
3.
Maximum ambient temperature is derated by 1 degree C per 300 m above 2000 m (not to exceed 2600 m)
1. The customer is responsible for HVAC system design, purchase, and installation
2.
The temperature requirements must not be exceeded at any point during the day (both
