What’s the Difference Between Water-cooled and Air-cooled Condenser?

What’s the Difference Between Water-cooled and Air-cooled Condenser-KOMEG

When purchasing an environmental chamber, there are usually two cooling options to choose from: air-cooled and water-cooled. Do you know the difference between these two methods and how to choose the cooling method?

Introduction of Condenser

1.What is refrigeration?

The process of cooling an object to a desired temperature using mechanical equipment.

2.The function of the condenser:

The condenser uses air-cooled or water-cooled method to cool the high-temperature and high-pressure gaseous refrigerant formed by the compressor into a liquid refrigerant to achieve the effect of cooling the refrigerant. More at Wikipedia

Compare with Water-cooled and Air-cooled Methods

  Water-cooled Air-cooled


  • Relatively low requirements on ambient temperature, especially in summer.
  • The thermal conductivity of water is higher and the cooling effect is better.
  • Quiet operation, low noise.
  • High power, stable performance.
  • Cheap price
  • Easy to move


  • Higher cost.
  • Inconvenient to move.
  • The requirements for ambient temperature are high, 5~28°C is the best, if the temperature is too high, it will affect the normal operation of the equipment.

Note: The main reason why the cost of water-cooling method is higher is that the water-cooled condenser needs to be equipped with a cooling water device. There are two cooling water devices to choose from. One is water-cooled unit: the cooling water can be recycled for one year, which is more environmentally friendly. The other is a water tower: cheap to build, but needs to be cleaned once a week.

How to Choose a Suitable Cooling Method?

1.Small environmental chambers usually choose air-cooled.

2.For areas with colder climates in winter, considering the possibility of freezing, it is generally recommended to choose air-cooled.

3.Consult with professionals in the environmental chamber industry.

4.KOMEG customizes solutions for you:

  • Customers put forward requirements.
  • KOMEG further inquires customers: environmental conditions, test products, etc.
  • Check whether existing products and previous product solutions meet customer needs.
  • Provide customers with proposals based on their budget.


All in all, air-cooled and water-cooled methods have similar functions. Whether you choose air-cooled or water-cooled methods, you should choose according to the actual use environment of the environmental chamber and the testing requirements of the product.
