Overview
The press uses a water chiller to regulate ink and press temperature. Both the ink tanks
and the blanket emit heat. The chilled water runs continuously through the press and ink
tanks to keep these parts at their nominal predefined temperatures.
The cold water comes in from the water chiller. The water chiller connects to the press
with a hose. The hose length should not exceed 20 m (65 ft). When there are height
differences between the chiller location and the press location. The differences should not
exceed 10 m (32 ft).
Monitor water chillers that are not connected permanently to a water source for water
replenishing. You may need to replace the water and water filter, according to
maintenance instructions.
