TVR replacements may make sense in many facilities, especially those seeing lower efficiency or those whose production processes have changed over time.

Thermal vapor recompression (TVR) units (aka thermocompressors) have steam nozzles that wear over time, resulting in lost efficiency. In addition, most evaporator duties are no longer the same as original design. This means that a TVR re-design for the current duties can realize significant performance benefits.

The first case is easy to evaluate and address. Steam nozzles should be assessed every annually and/or when you notice decreased efficiency from your TVR unit. Replacements nozzles can be purchased and kept on-hand for when they are needed.

In the case of changing evaporator duties over time, Caloris recommends an assessment of your current operations and goals contrasted against the original design of your evaporator.

Have your product runs changed in terms of volume or constituents since the evaporator was installed? Even minor changes to flow rates and/or stream characteristics can create issues in an existing process system, reducing evaporator efficiency.

This doesn’t mean that the evaporator, including the TVR Unit, cannot be re-configured to handle your current production more efficiently. Contact Caloris to have one of our engineers perform a process assessment, taking into account your current production goals. The process assessment will include recommendations for changes to the system to help accommodate your current needs.
