I. 10 Core Parameters You Must Check When Purchasing Low-Temperature Evaporation Equipment

1. Daily evaporation capacity (processing capacity) t/d

Determines whether it can meet your water volume requirements.


Key points to check: Rated evaporation capacity, actual stable evaporation capacity (many manufacturers falsely mark this).


2. Power consumption per ton of water kWh/ton of water

Directly determines the operating cost.


Heat pump type normally: 90 - 150 kWh/ton


MVR type: 20 - 45 kWh/ton


False marking of power consumption = doubled cost in the later stage.


3. Distilled water recovery rate %

Normal: 90% - 95%


A rate lower than 90% indicates poor design, easy foaming, and unreasonable concentrated discharge.


4. Evaporation temperature / vacuum degree

Temperature: 40 - 60℃


Vacuum degree: Absolute pressure 0.08 - 0.095 MPa


Excessively high temperature = high corrosion and high energy consumption; unstable temperature = poor efficiency.


5. Equipment material

Ordinary wastewater: 304 stainless steel


Electroplating / high-salt / acidic: 316L


Strongly corrosive: Titanium / Teflon


Cutting corners on materials = corrosion and water leakage within 1 - 2 years.


6. Heat exchange form (determines whether it is easy to block and its efficiency)
