The Air-Cooled Condenser
It is very important to keep the air-cooled condenser clean. This is where high-
pressure vapor from the compressor is converted to liquid refrigerant by rejecting the
heat gained from the vapor condenser into the ambient air. Reduced airflow over the
condenser can result in severely reduced performance and may shorten the life of the
compressor.
To maintain the air-cooled condenser and compressor:
Do not allow any paper products or cloth to slip underneath the unit (
e.g.,
1.
paper towels, Kimwipes®). These items will obstruct the airflow.
Always maintain at least four (4) inches of clearance on all sides of the unit.
2.
Maintain the room temperature at approximately 20 °C. Higher temperatures
3.
may result in reduced performance and shortened compressor life.
Clean the fins on the bottom of the unit. Dust buildup may cause the unit to
4.
malfunction.
Condenser Chamber
The condenser is fabricated from stainless steel. Under normal use, it can be rinsed
and kept clean with mild detergent. If corrosive materials are being freeze-dried,
thoroughly clean and rinse all parts of the freeze dryer that come in contact with
product vapor. Add baking soda or a mild buffering agent to the rinse water to help
neutralize acidic residue. A siphon-type squeeze bottle can be used to direct the rinse
spray into difficult to reach areas.

Keep these fins clean.
