AK Flush Press Release
AK Flush is the latest innovative product from A-Gas that provides a complete environmental solution when replacing refrigerants.
With an increase in systems being retrofitted following the virgin HCFC use ban at the end of 2009. It is essential to remove any unwanted contaminants inside the system including oils to reduce the risk of poor performance or system failure. As a result engineers at A-Gas have developed a non-toxic, non ozone depleting easy-to-use solution for flushing refrigerant and air conditioning systems.
AK Flush, has been designed with a range of polar solvents that dissolve and remove oil along with other particulates, sludge, acids, carbon residues and moisture to prevent compressor damage.
When carrying out a full retrofit including oil change particularly when an HCFC refrigerant is being replaced with an HFC, it is important to remove all traces of previous residues to prevent the new refrigerant becoming contaminated or bringing older contaminants back into the compressor. AK Flush is ideal for flushing through the system to remove contaminants and can also be used after a compressor ‘burnout’.
“AK Flush can be used on its own or as part of a comprehensive maintenance plan and provides an additional safety measure when retrofitting,” says Ken Logan, Managing Director of A-Gas.
A carbon dioxide propellant pushes the solvent into the system and the dissolved CO2 boils out of the solvent causing a ‘fizzing’ effect to aid cleaning. The non aqueous solvent blend has a low boiling point so is easy to remove after cleaning using a nitrogen purge and subsequent system evacuation. One 5kg pack is sufficient for systems up to 50Kw although systems with long pipe runs and wide diameter pipes may require a larger pack size which can be specified and priced on request.
Environmental considerations feature heavily in the design. AK Flush is delivered in a pressurised cylinder complete with an empty waste receptacle; both need to be returned to A-Gas via their nationwide wholesale distribution chain, once the job is complete. This will be handled as hazardous waste and reported through the correct EA Haz waste management scheme.
“We have factored waste destruction of the residue into the pricing, and made it as easy as possible for customers to have a one stop solution for dealing with system flushing issues, ” adds Ken.
