I should have explained further. If this condenser were to be used for air conditioning it would be rate @ 48,000 BTU's.
It is much larger than a power steering cooler.

my slush has always been a mixture of saltwater and freshwater (ice) ending with a saline solution. Can dressed fish be held in pure saltwater ?

That water pump looks like a TAMD 41 series or maybe AQAD 41 series with an outdrive?

Wait, what if you took a tote of ice with you and then when you got near the tender, you just put a bunch of ice in your RSW chilled hold, then it looks like you slushed the fish. I have heard the SPC won't buy RSW, maybe this might mask the situation and they would just assume they were slushed since they saw them in ice?

Would this system work on a smaller boat? Space and storage is highly limited and I use a full tote to store my fish, is there a way to adapt a rsw system to a full tote? I love the idea of getting away from ice, it's time consuming, labor intensive, and the cost and availability is also a headache.

Thanks Johnny, I'll look into it for the next season if we can manage to get one, hopefully there are some fish around to even need the chilling.

An interesting thread. Standard pros and cons. Fact remains ice, when available and packed correctly, consistently yields a better quality product. Before the proponents of refrigeration attack me look closely at the word consistently. I fill the boat up with ice, (I actually slush a tank and have four bonners on deck), and don't worry about it for a week maybe 10 days.
On the other hand, I have acquaintances, friends, running partners, and other assorted contacts that "refrigerate". Without exception, they rebuild, replace, or re-do something at least once a year and usually several times a season at considerable cost. What really cost them is when the system goes down with fish on board in the middle of a bite. Now they've lost fishing (production) time plus fix the problem. That's the consistent part. I've yet to see a consistently reliable refrigeration system, which delivers a consistently quality product, that doesn't cost +$20K. You get what you pay for. I can buy a lot of ice for $20K, or even $3K for that matter.

We have a IMS 7.5 ton RSW system, when testing the system, it builds 98 psi and then the high pressure light kicks on and stops building pressure. I have tried to reset the system via the black reset button on the control panel to no avail. the manual says there is a reset button on the back of the control panel but i am not finding it. any help would be appreciated.
