= Not allowed as standard but the coolant temperature must be 0 °C (32 °F) or above.
At an air temperature of 45 °C and relative humidity of 65% the coolant temperature may
not be below +36.8 °C
Example:
Maximum temperature rise:
Depends on heat losses and mass flow. Typically 10 °C (18
°F) with nominal losses and flow.
■
Pressure limits
Base pressure:
250 kPa (recommended); 300 kPa (maximum). “Base pressure” denotes
the pressure of the system compared with the atmospheric pressure when the cooling circuit
is filled with coolant.
Air counterpressure in expansion vessel (with ACS880-1007LC cooling unit):
80 kPa
Design pressure (PS):
600 kPa
Nominal pressure difference:
120 kPa with Antifrogen® L 25% coolant solution, 140 kPa
with Antifrogen® L 50% coolant solution. This has to be taken into account when
dimensioning the liquid cooling circuit.
Maximum pressure difference:
160 kPa
■
Coolant flow rate limits
The maximum coolant flow rate for all drive equipment is 1.3 × nominal. See the technical
data chapter for nominal values.
■
Cooling circuit materials
Materials used in the internal cooling circuit are listed below. These are also the only materials
that can be used in the external cooling circuit.
• stainless steel AISI 316L (UNS 31603)
• heavy gauge aluminum
