Ambient Temperature; Start Up Of The Chiller - Pfannenberg EB 30 Anleitung Zur Erstinstallation

OIL CHILLER w/o pump
Usually, the pumpless CHILLERS are inserted in a circuit already provided with pump. Refer to instructions provided by
the system manufacturer and check that the flow rate and pressure entering the REFRIGERATOR are compatible with
the values set down in the chapter of technical data
OIL CHILLER with pump
Usually, the CHILLERS with pump are utilized to cool an hydraulic system provided with reservoir; therefore, the filling is
directly carried out on the machine. Refer to the instructions provided by the system manufacturer
OIL Chiller Start-up
For Oil chiller is stricltly recommended:
Contamination level of system fluid should not exceed class 18/15 ( ISO 4406 )
-
- to follow stricktly the operating range of pressure and temperature recomended

10. Ambient temperature

When ambient temperatures are above +40 °C (+45°C / 50°C, depending on the model) or below +15 °C,
PFANNENBERG should be consulted. High ambient temperatures reduce Chiller capacity. Low ambient temperatures
require special controls. Special conditions apply when temperatures drop below 0 °C (32 °F). Fluid heaters may be
required to prevent freezing and to hold the fluid in the Chiller reservoir at a constant temperature in order to reduce
start-up delays while the fluid warms up to operating temperature.

11. Start up of the chiller

CAUTION:
PERFORMED BY QUALIFIED PERSONEL.!!!!!!!
NOTE: The following instruction will guide you through the start up procedure in detailed steps. For
a quick commissioning instruction please see appendix A1 or A2.
NOTE: For PWW unit start up please follow the Appendix A2 (except verification for phase check
of 3-phase models, which is described in this paragraph).
Please consider that secondary circuit is a close loop system which has the pump installed inside
to the unit. Primary circuit is an open loop circuit, and the pump has to be installed from customer
outside to the unit
