Nu Calgon 4050-08 EasySeal Direct Inject (Packaging may vary)

Q: Does this come with the injector or does it need something else?

This product does not come with a injector. Service hvac handset is needed. To inject product into system.

Q: can i use this product for 3 Tons unit?

Yes you can this package is good for units from 2Tons up to a 10Ton unit.

Q: Does this have dye in it?

The manufacturer states that "And now the industry’s leading refrigeration sealant has been combined with UV leak detection dye to give you EasySeal Direct Inject-UV. This product is designed to seal leaks and also show where larger leaks are with the use of the UV Leak Detection Kit (4050-15)." I used it over a year ago and do not remember whether or not it had a visible dye in it. Sure did the job and I can recommend it. I used it on a Water Source heat pump and the leak had to be in one of the two water to refrigerant heat exchangers. I still do not know which one.

Q: Can this product be used on a refrigerator? if so what tons do I purchase. Can too much be a bad ting?

Hi! The first thing I would do is call the refrigerator manufacturer and discuss this with it's Tech department to see what they say and if they have any recommendations (besides buying a new 'fridge!).
