Pump | Vacuum | Heat Exchanger Technologies | ESI

Vacuum Technologies: In recent years industry has seen a large focus on controlling waste or emissions. The Liquid Ring Vacuum pump is still considered the workhorse in the vacuum industry, however it does use water (or other liquid to form the vacuum seal liquid) and any liquid .

Vacuum Systems with Pump – Equirepsa

In the case of total recovery, there is a total recirculation of the sealing fluid.In this case, a heat exchanger (plates or shell and tubes) is added to the system in order to dissipate the heat of compression and condensation from the sealing liquid before being reintroduced into the pump.

Waste heat becomes a source of energy - Efficiency element .

The operating fluid (oil) heats up during compression. Its heat is transferred to a water circuit in the heat exchanger. Water-water heat exchangers are suitable for liquid ring vacuum pumps, among others. In this case, the heat from the operating fluid (water) is transferred to the heat .
