HRR Series 3.2 Installation
3-3

Thermo-chiller installation in high altitude of 1000 meters or mor e
Because of lower air density, the heat radiation efficiencies of the devices in
the product will be lower in the location at altitude of 1000m or higher. For
this reason, the maximum ambient temperature for the thermo-chiller
operation and the cooling capacity will be reduced.
For product installation at a place of high altitude of 1000 meters or more,
select a thermo-chiller of the applicable capacity referring to the table below.
1. Max. ambient temp.: Use the product in lower ambient temperature than
the described value at each altitude.
2. Cooling capacity correction coefficient: Coefficient to calculate the cooling
capacity at each altitude

At an altitude of 1800 meters = Cooling capacity 8.4 x 0.8.

Installation/Operation in accordance with the UL standard
The product cannot be used in the environment shown below:
●
Environment at an altitude of 2000 meters or more
●
Environment at a pollution degree of 3 or more
