T-Drill and REMS Curvo saves big $$s

hr

Express Lube job I am doing. Three- 350K waste oil boilers are stacked and tied into a floating free standing 2-1/2" primary loop. Thanks to Bob Warner for that idea!

The primary loop allows 8 hydronic unit heaters and a largwe Ergomax indirect a place to join in the party.

The T-drill saved me 20- 2-1/2" tees at about $25.00 each! The Curvo saves a dozen or more ells of various sizes from 3/4" to 1-1/4"

Also to be considered is the flux, solder, actylene, and labor that 20 sweat tees would have added to the job. With the T-drill only one solder joint is needed per connection.

Add it all up and probably a grand ($1000.00) worth of parts and labor savings. Fairly quick payoff on these tools when you start working large diameter copper.

Little if any pressure drop between T drilled branched. The fluid merely sees an open window as it passes by :)

B&G sweat iso check flanges were also used on every branch.

I did have to use 4 ells as I mis calced a few dimensions for the Curvo, and needed to keep thing tight in a very limited mechanical room space. Hense the 3 stacked Clean Burns.

A tekmar 264 will be the brains behind the brawn.

Awesome work HR

Great looking work!

I have quoted so many clean burns over the years. Are you pursuing a yearly service contract for these units?

very nice work

hot rod did you solder the tee connections or were they brazed. I was always taught to braze tee connections to strengthen the joint.
Aa usual your work is nice to look at

PL130??

Is that a PL-130 primary circulator? Those PL series are excellent. I just received pricing and availability on the new Taco 1400 series which will be their equal to the B&G PL's.

Gorgeous HR!

I have the T-drill, but I gotta tell ya that REMS Curvo is really tempting me. The bad thing is, I know that I couldn't just immediately start cranking out the kind of work I see you doing. That tool has a learning CURVE.
(pun intended, aint I awful)

Yearly???

It has been my experience that under some conditons these units need to be serviced MONTHLY. Make sure the owners are aware of it. They think all heating systems are a set it and forget it proposition.

Treat the fly ash as a toxic material. It contains babbit which is a close relative of lead and suspected carcinogen.

Good idea, but very maintenance intensive, and very few knowledgable people to work on them...

Great job as usual HR. Keep raising the bar and thinking outside of the normal pipe, valve and fitting box.

yes you could be a bend artist quickly. I used some scrap PAP to practice Bending software is very inexpensive if you want to get real fancy. Do a web search for tube bending to find tips and tools.

PL power! brazed joints, etcx

a very good pump for the money. This has 36's on the boilers, 40 on the Ergomax, and a 130 primary.

Armstrong also has some open frame, affordable, circs on the market.

The Clean Burn dealer/ distributor for this area handles the cleaning. They have the knowledge and equipment, and desire, to do it! They built a clever cart to hang the burner on and circulate a cleaner through. Then they replace seals and o- rings. These waste oil burners are a bit of maintenance issue!

I braze everything above 2" copper. Lots of thermal stress in a large loop that may go from room temperature to 180 in a few minutes! The braze give additional joint strength and allows some movement at the branches due to the softening of the pipe when it is heated and brazed.

It allows some "plumbness" adjustment also when you T drill. You can tweak the branches a bit to get perfect alignment. Fun to silver braze, ocassionally Be sure you have a torch that is up to the task. We used an oxy/ actylene rig with a small rosebud tip.

Very professional Hot Rod

did you use the Powered Tee Drill for around $2500 Or the less drill version by M&S Valves? I'v been wanting a Tee Drill for about a year know but the price has been scaring me a little.How much did the Curvo set you back and how big of a pipe will it handle?

so the most complex bend i made so far is...

two 45'son the run with aswooparound the corner at a different off set to two refridgeration 90's in a "uie"designed to let two completely different sets of closely spaced "T's" to go "by" i just love this gizmo *~/:)

Really Nice HR

Great looking work.

Have you ever had a problems with the t-drill ? Every time I look at it it seems like such a small joint. What type of brazing did you do, I mean what type of rod ?

Ilove the job.
