BV2 starts closing the bypass line over the heat exchanger (HE) at the lower limit of its temperature range.
At the upper limit of its temperature range, the bypass line is completely closed and all the oil flows
through the ER heat exchanger.

On compressors versions with a maximum pressure lower than 13 bar (175 psi), BV2 starts opening at 40
˚C (104 ˚F) and is completely open at 55 ˚C (131 ˚F).

On compressors with a maximal pressure of 13 bar (175 psi), BV2 starts opening at 60 ˚C (140 ˚F) and is
completely open at 75 ˚C (167 ˚F).

The oil cooler bypass valve (BV1) starts closing the bypass over the oil cooler (C0) 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 (C0).

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 (C0) 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).
