Position of valve housing of BV2 with wheel V1
ER label
Attention: It is only allowed to turn the wheel completely in or out. No in-between position is
allowed!
The oil cooler bypass valve (BV1) starts closing the bypass over the oil cooler (Co) at the lower
limit of its temperature range. At the upper limit of its temperature range, the bypass is completely
closed and all the oil flows through the oil cooler (Co).
BV1 must have a higher opening temperature (set point) than BV2 in order to prevent the heat
from being dissipated in the compressor oil cooler (Co) rather than in the oil/water heat
exchanger (HE) when using the compression heat as source for energy recovery.
Thermostat BV1 starts to open at 75 ˚C (167 ˚F) and is completely open at 90 ˚C (194 ˚F).
Energy recovery system in use (see drawing)
The wheel (V1) of BV2 (bypass valve of the HE) is totally turned in clockwise.
