Technical data
Data for TXI configuration (cover and 5 HPPR modules), an X-BB module is in-
cluded by default:
Dimensions (w × d × h in mm) 260 × 350 × 420
Weight 25 kg
Water chiller (optional) 3.4

The He Compressor generates about 7.5 kW of heat. If water-cooling has been
chosen but no cooling water is available, a water chiller should be used. Fresh
water is not recommended because of cost, purity, and environment protection.
Technical data
The following example is valid for the water chiller available from B
RUKER in Eu-
rope. It is of the ‘split type’, i.e. it consists of two units: a main unit indoors with
pumps for a primary and a secondary cycle linked by a heat exchanger, and a ra-
diator outdoors that disposes the heat from the secondary cycle to the atmo-
sphere. Local suppliers in other parts of the world are likely to offer similar
devices.
