What would the justifiable gains be of having a single pass HE120.3 over it's current form?? (I'm not being sarcastic, just wondered if you could explain your particular need for it... from what we've seen of other single pass rads on the market, they appear not to be selling particularly well and bearing in mind minimum quantities for manufacture to keep the price as it stands for current HE120.3, it's a risk making up a batch that may sit and stagnate over a year... If there's a justifiable reason and necessity for a HE120.3 being made in single-pass form then it's easier for me to get it approved by the powers that be...)
Sidenote: for those interested I added production photos onto the ThermoChill site showing their fabrication in progress... see
