The gas consumption of the absorption chiller for commercial facilities has been maintained at about 20% lower than during peak times.
It is a large commercial facility that opened in 2002, using a gas absorption chiller for its air conditioning heat source. Although the condenser and absorber were regularly cleaned with brushes every year, the consumption significantly increased each year until 2005. In the spring of 2006, a chemical cleaning was conducted, resulting in an approximately 20% reduction in annual gas consumption. In response to this, a ball cleaning device was introduced to prevent efficiency decline due to dirt in the heat exchangers.

Absorption chiller for commercial facilities Absorption chiller for hospital and building air conditioning Absorption chiller for production lines Even with the introduction of high-performance chillers, if the condenser and absorber are dirty, their capabilities cannot be fully realized. Please consider upgrading to a chiller that does not get dirty through ball cleaning for your heat exchangers.

Company information
The costs of electricity and gas for air conditioning have become a significant issue that cannot be ignored. No matter how efficient a refrigeration unit is, if the heat exchanger is dirty, its performance can be halved. Even with regular brush cleaning, it may remain dirty for most of the operating period, leading to increased maintenance costs. For those who have not encountered a method to "keep the heat exchanger clean," I hope to introduce a way to maintain the heat exchanger in a clean state without incurring high costs for water treatment, without needing to perform brush cleaning once a year, or chemical cleaning every few years.
