Economical for small cooling demands

Cooling using air is the most economical method of cooling. 

Because of physical limitations, the cool water temperature cannot be brought any lower than the ambient temperature, because this kind of chiller cools with help of a fan and heat exchanger directly against air. 

These 500 watt (at 35°C) chiller are particularly but not exclusively suited to water distillation units or certain AAS.  The optional cooling capacities available with this kind of chiller can be up to 100 kW. 

The airflow is from left to right.

This type of unit is also available in a 3000 watts Version and with increased temperature stability.

The illustration opposite shows the model COOL-AIR on the back with option tank emptying.
