It is just on 5 months since I gassed up my custom AC unit with HyChill-30 It is a 32000 BTU unit with fairly long hoses and took 300 g of HyChill-30 The pressures were 25/175 psi and the temp off the evaporator 6.1 c The pressure in 123rover50 s system being slightly higher may be due to the extra gas ?My system works very well with temps in the thirties the passenger window fully down the dog acting as a turning vane:( the 110 still comfortable:BigThumb:Hychill-30
