Kia Ora Hi Folks
Has anyone worked on one of these units. I have a situation where I was having difficulties in getting low temperatures on an off cooling coil. Temperature on 25c 23 off. freezing icing at 79.4Kw TX Valve. I have since replace the valve I now have 9c accross coil difference. BUT my back pressures120psi are extremely High with low hp.120psi.I have shut back on TX but then I loose my tempersture difference accross the coil.

Suction valves in Question or loaders perhaps.
Thank you.
