Heat recovery

Process cooling is an unavoidable process in which all generated heat must be cooled down to keep the process stable. Depending on the process, these are a few kilowatts to megawatts or more. Harvesting this energy and doing something useful with it will be the challenge.

Very low pressure drop due to special designs

All heat recovery systems are calculated in-house by Oversluizen. With the practical approach that our company has for the development of specialized cooling systems comes in handy. We distinguish 2 different processes:

  • Recovery from gases (exhaust gases from engines, processes or turbines).
  • Recovery from liquids (water, glycol, hydraulic oil).

Gas/air warmteterugwinning

One of the more important requirements in heat recovery, from both existing and new processes, is resistance or pressure loss that this entails. The advantage becomes smaller if the process starts to perform worse due to the extra heat exchanger.

In our portfolio we have systems that are suitable from -160 degrees Celsius to 600 degrees Celsius. Even ‘running dry’ is no problem with certain types.

Liquid Heat Recovery Backup Engines

In the maritime world, backup and redundancy are essential for keeping shipping safe. For this, Oversluizen has a compact heat exchanger that, despite its small size, has a very low pressure drop and can therefore be placed in the cooling water system as an ‘extra’ cooler without a reduction of the cooling water pump as a result.

Fluid Heat Recovery Hydraulic Oil

Due to the high maximum working pressure of 16+ bar, it is difficult to recover heat from hydraulic oil without the need for large coolers. Volume flows from 10 l/min to 1800 l/min or more are no problem at all, with resistances that must remain below 0.1 bar.

Electrification – Heating

Commonly used in electrification projects, we use the heat of the hydraulics to heat the cabin. The entire volume flow is allowed to pass through the cooler, whereby Oversluizen takes into account the required pressure drop and heat recovery.
